Ooops I did it again... I could not resist to pick up this Cromemco with AMD-3A+ (And another dull terminal) nearby. The owner bought it somewhere in the eighties but never used the system. So it has been stored for over 35 years in his attic. Since they have to move to another house they had to let go of a lot of stuff, and also this machine...
I've powered up the ADM-3A+ on the variac and it just works fine. This is the 74LSxx series with cursor control and it is from 1980. My other ADM-3A is the older SN74xx model without cursor control. But that terminal is from 1981. So the older model is actually newer
The Cromemco itself was completely dead. That was caused by a broken fuse holder. I've seen this more often, people put a machine on its back and something snaps off. After replacing and also slowly powering it up it came to life. Sort of... The thing is that I didn't get any software with the machine. I tried to become a member of the Cromemco group, but for some reason I can't become a member there? You have to be invited?
I think my system is a very basic system. FCD controller, ZPU board, Memory board and a printer controller... But it would be helpful to know which exact disk images work on this machine...
