Legacy Technology RAM Boards - A Question for UK Modders.

Is that an S100 format card Pete?

Looks very similar to one I used in my first 'proper' home made PC based on an S100 bus and a Z80 running CP/M - I  think it was a 'Tinker Toys' card that I had to import from the US.

Hi there, Andrew,

An eBay seller in the USA sold a Motorola prototyping board - here is his reply to a question similar to yours:

Here is a prototyping board that fits the bus used on the Motorola MEK6800D1 and MEK6800D2 Microprocessor development boards.  I received this board in an S-100 purchase but was unsure of what it was as it definitely was not an S-100 board.  I came upon an eBay listing for a Motorola MEK6800D1 kit and I recognized the bus layout immediately as I had been trying to find the system it belong to for a while.

I have some more information courtesy of a kind eBay member:
 
This fit all of the MEK series the MEK6800D1&2, MEK6802D3, MEK6802D5, the Micro Chroma 68, The 68000 series MEK68KDM, etc. They were all made to be able to plug into the Motorola Exorciser systems. All with the same 43 edge connector pins (and basic pin out) on each side.

Thanks for looking at my auction!

I'll try to post a page giving the pin assignments tomorrow.

Here, I hope, is a link:
