What is this ?

[ukl]

hello,

after selling a eurocom 1 (a single board old computer), i found some more (i think) for this system, maybe someone is out there can tell me, what i found ?

The first board has an 6802 on it and a dip-switch with titeld with ACIA/PIA/RAM/ROM

The second board might be a Ram-Card ?

The thrid mihgt be a complet computer ?
There is a tag on it with "6809 CPU 96K V2.2"

The fourth could be a Tape-interface ?

thank you for your help

That fourth one has a lot on it to be just a tape interface. Looks more like a CPU board, since it has a 6809, RAM, and the ROM Assist OS.

Looks like the first one is also only selected to act as ROM and PIA.

The second one is definitely a RAM board from the notes on it. It will get turned off if DESEL (NOT) or I/O (NOT) are set to zero.

Just some thoughts, as I am unfamiliar with this specific machine.
