I did say I was a bit obsessive about information on a topic... I am trying to record all this in one place but, it is getting so big and interconnected I think maybe it will be enough for a book!

I only have a PIC16 kit I picked up recently - never done anything with them so it was a curio. I will probably have a go at KarenO's machine one day as a suitable project to find out about them. I have a few blank EEPROM's so that sounds like a good way to try it - thanks.

I will look forward to your insights on the Graphics modes.

If you really want to blow your mind read the Manual update letter - it is full of interesting snippets...

http://www.computinghistory.org.uk/d...Update-Letter/

> An updated PROM was available that supported a teletype terminal - that makes the EX42/44 project more interesting in relation to this - I wonder if any of the boards still in existence have that instead...

> They were planning a 2K Memory expansion card (so our intention is in keeping) and it confirms that 1,2 and 4 boards can be modified (wonder what happened to III). And that Issue 5 are already done.

>A 16 way A to D card.

>Advanced calculator interface - to use the calculator as a maths co-pro!

Really interesting:

>BASIC Language board - this seems to support my theory that the published NIBL BASIC program in PE April 1979 was perhaps done on a prototype MK14 BASIC expansion... definitely worth doing now...

They say this needs the VDU card (which they hoped to release in January - (1979 I assume) and the also announced 40 Key Keyboard which would came with another SCIOS update... - other items due March (again I would assume 1979)

I also notice that https://twitter.com/mk14man has started posting again intending to get his AVR based one finished. His latest tweet also posts the link to the Powerpoint he gave at the ParlaBytes Spanish Retro event in 2015 which I had discovered recently. There is also a video of the talk online as well (in English):

and here is the link to the Powerpoint as it is hard to see in the Video...
