A few goodies

I purchased a full set of Einstein manuals from eBay recently, and took delivery of them today.

We have;

An introduction to ..
DOS/MOS Introduction
Einstein Primer
Basic Reference Manual

Within the shipment was some additional material!

A vintage Sharward Service flyer/PD price list – 8 A5 pages of prices and hardware/software – I have not seen one of these scanned anywhere!

Sharward Services are still operating as a company, and I have contacted them via eMail and received a reply from Sharon, who is an original employee from way back ..

A hand written page on using MOS to program Z80 Assembler and save as executable files. Who ever had these before me, seemed to know what they were doing.

Additionally I purchased

Einstein Compendium – This is the official U.K.E.U.G (UK Einstein User Group) book with tricks, tips and listings – Released in the mid 1980s

Infrared Photography. Pictures in a whole new light!

This is a copy of a post from my old Blogger site – Circa 2010. Brought back to life here now that Google + and associated data is being closed on April 28th 2019!

Not so much Retro as oldish Tech Hack

One of our old digital camera’s got scared and leaked its battery juice all over its insides and stopped working … so

Easy project to convert it to an IR camera whilst cleaning the acidy goo from its innards;

Vivitar 5188 – 5MP CMOS camera – Dead cheap and came with a wicked underwater housing;

Step 1, remove all the screws;

Step 2, remove the front and back case. Be carefull of any wires that are still connected.;

Step 3, carefully unscrew and remove the lens assembly;

Notice how the lens is red in colour, this is the filter that blocks IR light in normal operation. This has to be removed (carefully of course).

I did try to scrape away the red coating, but scratched the lens 🙁 – removing it seemed the sensible option as its not a focusing lens and not really needed!

Step 4, get yourself down to the local photo processing place and ask for some film that has been developed but has no image (It should be almost completely black when looking through it) – There may also be some on your own negatives. I was lucky and had 1 frame of completely exposed and developed film with no image on it.

Cut out 2 disks the same size as the lens and place them back to back so no visible light can be seen.

Secure them in to the lens housing with 2 spots of superglue (1 on each side) making sure you do not cover the screw thread on the lens.

Step 5, re-assemble the lens in the camera holder and tighten as far as it will go, but do not over tighten as you will touch and then destroy the CMOS sensor and this mod will be useless!

Step 6, start taking surreal alien like pictures with your new IR wavelength camera!

What do you think then eh?

Google+ is closing!

I had an eMail from Google to say that Google + is closing on 2nd April 2019 because its hard to maintain and no one uses it! – Well we all can’t be Facebook can we?

Because of this, I have scoured my old Blogger posts and saved some here as well as backing up all my google + data (What use that will be I have no idea)

Over the course of the last 10 years I have only had 3,746 views in total! – Not worth the effort? Well, that is why I have not updated that blog in 6 years!!!!

Here are some of the highlights!

Posted in June 2011:

Found this underneath a load of books in the office!

Taken I think in 1980-1981 at Duke Street Primary School in Denton.

Soooo many faces I have not seen for many years!

That is me circled in red! Haw haw!

I think Mr Hinds who was the head teacher (At the back in the brown suit) passed away a few years back. 🙁 he would have been in his 90s I bet?

We are all nearly 50 now – Some closer than others!

Also Posted in June 2011:

Dum dum dum, dum de dum, dum de dum!
Dum dum dum dum de duddle dum, dum dum, dum de duddle dum dum dum, dum de dum, dum de dem!

Here is my newest acquisition in all its glory! A genuine 1981 All Terrain Armoured Transport.

The only thing it is missing is the chin lasers. 🙁

I have not tried the lights or sounds yet, so once I have some large batteries I will be firing her up! 🙂

Update: This is fully functional with replacement chin laser cannons and is now complete with original 1980s pilot and commander figures.

Posted August 2010:  (Links updated Feb 2019)

So my 2 Philips SPC880NC’s turned up at weekend; Bog standard CCD web cam. Unfortunately these do not work under Windows 7! 🙁

Fear not. There is a way to hack them to into SPC900NC’s which are recognised by Windows 7.

So … Both have been patched as per this web site; and are both seen in Windows 7.

One is to be modified for connection to my microscope, the other is to be a spare in case my proper astro scope bites the bullet.

For £12.80 + vat for the pair, I don’t think its a bad investment?

To PAD or not to PAD?

I have an AKAI MPK mini 25 note keyboard with drum pads. Its a mini USB keyboard that works with loads of music software and DAWs.

This is a great piece of kit, but due to its portable size, does not have pitch or mod wheels;

REASON is my music software of choice, and many years ago, I found a blog post on how to re-use old PDA’s as KAOS pad replacements in Reason or any other midi composing software.

I have transferred it from my old blogger site which is being closed down on Aptil 29th 2019.

Searching the web does not produce much other than 2 ideas.

1. Sell the keyboard and buy the AKAI APK49 – larger keys and pitch and mod wheels

2. Use a Pocket PC as an X/Y pad for pitch and mod control.

This is the Retro aspect, otherwise this would be too modern for me!

Number 1 is out as I just bought the thing and love its compact size… So.

The second option it is then;

I use Reason Essentials 1.5.1 as my main DAW (Or try to as I am not very musical, ROFL)

Here is the process I used to get a vintage Windows Mobile 2003 Pocket PC (Dell Axim X30) working as an X/Y pad with Reason 10. (just like this one, but I have run it on many different versions of Pocket PC as long as it can run .Net framework!)



Using google, search for LoopBe1 midi loopback driver – LoopBE1, download it and install it to your main machine

Install Active Sync 4.5 if you are using Windows XP, or use Windows Mobile Connection centre if you have W7 – Not sure about Windows 10 as I use this on a retro specific PC,

Search on google for Theresa Pocket PC Theresa Download and download the ZIP file and extract it to your desktop to a folder called Theresa

From the Theresa folder on your desktop, copy the server folder to somewhere accessible on your main machine and create a shortcut to the .EXE file (So you can run it easy when you need it) – You can set it to auto load, but I dont like too many things loaded unless I need them

Connect the Pocket PC to your main Pc and allow it to be detected and with Active Sync or Mobile Centre, then cancel when asked to set up a partnership (This is not needed. You can set one up if you wish though)

Explore the PDA/Pocket PC device and copy the client folder from the Theresa folder on your desktop to somewhere on the PDA or a memory card

Run the server exe file from where you copied it and you will get a new T icon on the task bar – It should have a little red dot at its top right

Run the client exe on the PDA

You will be presented with the main Theresa screen on the PDA. At top right is the power button to close the app. Next to it you will find the config button. Select this and you can choose which port the software will affect.

Click on the top option (DEVICE:) and you will be presented with a list of available ports on the PC. Select the LoopBe1 Midi driver/port and click ok. You have now set up Theresa to output midi data to the correct PC input driver

You can also change the skin of the software to match one of your favourite ‘Real life’ Midi Controllers

On your main PC, fire up Reason or Essentials or any other DAW you use (They should all work about the same)

Edit preferences and add a new control surface as ‘Other’, do not do an autodetect as nothing new will be found.

Now select the Advanced tab and enable loopbe1 midi driver as another input device.

You should now have 2 green ticks for input devices (one for your main input keyboard and another for the PDA X/Y Pad)

Close the window and add an instrument to Reason – Test it with your keyboard to make sure you get sounds

On the Theresa screen you will see little numbers in the green bar above each slider/pad area. This is the MIDI number that is transmitted when Theresa is used.

Click on each number to change it to your preferred MIDI channel/note/value etc

I changed the botton left vertical slider from 105 to 110 (This is the value of the LFO rate for OSC 2 in SubTractor analogue synth module)

Play a note and move the slider up and down with the PDA stylus – your synth sound should change as you move the slider, or whizz around on the top left pad.

Voila – a cheap (if not free) X/Y Midi controller – Its not quite a Kaosscilator or a Korg Nano Pad, but its not bad.

(I will add more screen shots as and when I get chance)


Games for your?

On the back of the Cassette 50 post, I thought I would share another set of retro ephemera from back in the day.

I am trying to get a full set of these, but they appear to be like rocking horse poop! – Extremely Rare!!!!

Games for your …. ‘Personal Computer of Choice’

All the major systems of the time had a book of games dedicated to it, that you could type in and run.

I recall, many of the games had small bugs that needed to be corrected, which helped you learn how to program.

Published by Virgin books in the early 1980s, They were all edited by Tim Hartnell.

They all originally retailed at £2.95 each.

After extensive research, I have determined that the following machines had it available.

The ones in large bold type below are my own copies!


ZX Spectrum

TRS 80

Apple IIe

BBC Micro

Amstrad CPC

Atari 8Bit



In quite poor condition – The spine is ripped and missing print.

Commodore 64

Dragon 32


Atari 600 XL

Recently (April 2019) acquired via eBay

Sinclair QL

I need a better scan of this book cover! – Who has one?

Acorn Electron

I need a better scan of this book cover! – Who has one?


There was an additional series that followed on from the above called …

Wait for it …

Thats right!

MORE games for your …. ‘Personal Computer of Choice’

So far, I only have this for the BBC Micro, ZX Spectrum and ZX 81

Its’ a HARDware life

I have finally got hold of a Tatung Einstein Hardware Reference Manual. A physical copy!!

Its huge! – 12 inches tall by 8.5 inches wide and about 100 pages.

As with many books from old book shops, there is a musty smell to it, but I have to say, this looks to have been lying around for a long time. It needs a damn good airing.

I never had this in the late 80s when I originally owned an Einstein, so this is a revelation! Sure, I have read it online in PDF format, but there is nothing like having the printed matter in front of you for reference.

This should allow me to tinker properly and diagnose why my Einstein is poorly!

Tatung Einstein Emulation

While I am waiting for a fix for my poorly Tatung Einstein, I thought I would get some emulation configured so I have refreshed myself for the actual hardware.

Here is how I did it.

  • My OS of choice is Windows 10 – Your OS mileage may vary!!!
  • Go to http://www.emulator-zone.com/doc.php/misc/mess.html scroll to the bottom of the page and download the preferred flavour of MESS. I am using the 64 bit version
  • Install it. I chose c:\software\mess as the installation directory
  • Go to http://messui.1emulation.com/ find the MESSUI download section (About half way down) and find the matching version for the MESS you downloaded in step 1
  • Extract this 7Z file over the top of your mess install folder and overwrite when asked
  • Open a command prompt (I did this as administrator)
  • Navigate to the MESS install folder c:\software\mess
  • Type mess -cc then press enter/return
    1. This will create a default configuration file (mess.ini)
    2. Using your favourite text editor, edit this file and change the file paths by adding the MESS install locations in front of the folder names IE: rompath c:\software\mess\roms
    3. Save the new configuration over the existing file and exit from the text editor
  • Go to http://www.tatungeinstein.co.uk/front/messmame.htm scroll to the middle of the web page and follow the instructions for downloading and saving the 3 files needed for the emulator
  • Run MESSUI64.EXE from the installation folder and you should be presented with the GUI to launch your system
  • In the top right search bar, type Einstein and you should have 3 systems listed in the middle of the screen
  • Ignore the no entry icon – this appears to be a bogus warning and is infact working!
3 Einstein machines available, floppy image selected and preferences set
  • Highlight Einstein TC-01, right click and select properties
  • In the Audit tab you will receive an error about the rom not being found, but this is a bogus error as the emulator will run fine. Check the settings for this machine an when you are satisfied, close the properties box
  • In the 3rd column of the main screen you have the option of inserting a disk image into the virtual floppy drive on the einstein. Click on the ‘Assist Edit’ button to the right of FloppyDisk1 and select Mount File
  • Choose a zipped Einstein disk file. I chose XBAS.ZIP
  • Double click on the Einstein TC-01 entry in the machine list and you should get the emulated machine booting
  • If the window is too small, maximize it like a normal window and it will scale properly to the correct aspect/zoom level. Be warned, the original Einstein screen was 280×216 pixels so the zoom will be excessive!
Too small
Maximised to full dispay
  • Press OK to access the emulated Tatung Einstein
  • To reboot the machine, use CTRL & left ALT keys – This performs a CTRL & Break sequence from the original machine
XtalDOS and XBasic loaded from disk image archive file
Demo.XBS loaded and run
The Einstein demo runs sweet!!!

And thats your lot! – You should now be able to properly emulate a Tatung Einstein TC-01. The same instructions should work with the Einstein 256, but I do not own the rom file for this version so haven’t tried it.

An old article I wrote

Doing the google 2 step recently for Tatung Einstein related sites (There are not that many available now) I came across an article in The Centre for Computing History’s pages .. Written by ME! – I had completely forgotten I had written it .. Happy days.

There is no indication when I wrote it but it must be at least 5 years now, if not much longer ago!!!


Here is the page transcript;

Tatung Einstein

By MikeHalliday.

Ah, this brings back some memories. – I got one of these babies from an electronics outlet in Manchester in 1988. (I think they had been heavily discounted by then) – It came with XTal basic, CPM and a few games on 3″ disk 🙂 – These were a joy to use after the cassette trauma’s of the Speccy, but were riddiculously expensive at the time. Something like £15.00 for a box of 5. 🙁 – Imagine if blank DVDs were that price today, there would be an outcry!

Touted as being a BBC Micro beater for school work and business, its a shame it never caught on. By this time I think that Z80 cpus were becoming dinosaurs destined for the charity shop or car boot.

I remember the keyboard. It was the best keyboard I had ever used (Up until then, I had used the rubbery Spectrum keyboard and a data general terminal keyboard connected to a huge mainframe at college) – it had excellent travel and a re-assuring click. (I still use an original DELL 104 key UK PS2 ‘clicky’ keyboard from the early 90s connected via USB – the oldies are the best!)

Games on the Einstein were simple, but that was the era – no alpha mapping, voxels or texel engines, no realtime raytracing or internet multi player modes, just games that made you think and had you hooked for hours.

It wasn’t the fastest machine in the world either – 4mhz and I can’t remember if it had the same colour clash issues as the ZX Spectrum, but it certainly had the same tinny sound as the good ‘ole speccy.

What made it special for me was the external hardware spectrum emulator. A huge white box that dangled out the back of Einy and allowed me to load in some of my favourite spectrum games and play them. They ran at full speed because the little white box was an almost complete spectrum! 🙂

I also remember the 80 column card. An even bigger grey/off yellow box that allowed you to connect a ‘High res’ green screen monitor to the Einstein and run business apps (like a true professional). Then there was the printer!!! OH BOY. 132 column Epson parallel port DOT MATRIX monster that made such a racket that I never really used it – Ha ha.

Memories, memories! 🙂 – I’m getting old.

If you had an Einstein, you can (legally I think) re-live those memories at http://www.tatungeinstein.co.uk/ – I have tried the emulator and it is uber accurate. I was able to play all the old games from my late teens…

(Preservation of our history in any shape or form is essential for future generations to understand the stages of progress that have brought us to here and now)

Give it a go.. Re-live the late 80s, then go and see the real thing at the The Centre for Computing History, or on one of their many uk tours/exhibitions.

Thanks for all the work you do preserving our great I.T history. Without this museum British treasures would be lost for ever.

Extra Special Vintage

Finally …

I have acquired a Tatung Einstein TC-01. 🙂

I have bought one with dodgy/faulty video output off eBay for, more than I wanted to pay but still, a cheap price.

It has corrupted video output, but does power on without smoking!

It won’t be received here until second week of the new year, so I am preparing all the tools I need to get it up and running again.

There will be a teardown and refurbish/retrobrite video on my YouTube Channel very soon so you can all see what steps I took to get it up and running again.

These machines deserve to be rescued and saved for the future. They are old, rareish and excellent machines.

As you can see from the images below, the machine itself is in fairly good nick. Other than the video not working, it appears to be 90% working. I should be able to fix this very easily and at very little expense. I have also purchased a 6 pin din plug so I can make up a vga/rgb monitor cable to hopefully connect to a 15khz compatible vga screen that I have.

I have a spreadsheet to log serial numbers as I would like to compile a history of this amazing machine, as there is no indication anywhere of how many are still alive and kicking around.

If any of you have a real Tatung Einstein, please leave me a comment on this site with the following information (Serial number, condition and what extras you have [twin drive, external drives, hardware etc]) and I will update the Spreadsheet on a regular basis and may even post the results here;
