Today I Received...

These arrived today - a good way to support the Centre for Computing History (https://www.computinghistory.org.uk/) and get a little extra something for your retro collection.

Top Trumps ?

OK, ordered Expensive shipping, but my young one is driving me insane with horse-based card games, it's worth a try...

How would you decide which trumped which: Z80A, 6502... Holy wars have been fought over less.

Didn't realise that the Altair 8080 shipped with a mere 256bytes of RAM!

A nice little find on Ebay

What's it?

[Pr0f]

Its a self contained board, the large chip is a philips 90c100 - which is 68K code compatible, it is mostly hardware compatable too, but has on board serial and I2C driver too

The board has 32 I/O lines - 16 can be used to drive an 8x8 keyboard matrix, the other 16 are places on the 50 pin connector. It has on board clock chip and 4 channel ADC and 1 channel DAC - for analogue signals. Also supports a standard 2 line LCD and RS422 output. It came with some documentation, and images for the 2 missing ROM chips - so tempted to fire it up and see it working.

I did wonder if Tony Tebby's Stella might run on it, but never seen the software anywhere. It runs a Real Time OS called MINOS and can run programs written in Modula-2 or 68K assembler.

I will try porting EHBasic to it as that runs on a 68K

Looks like a professional made board (PSY Systems...as printed on the top of the board?) Never heard about it.

I think it was designed for industrial control type applications - but packs quite a punch in a small board.
