Digital DECmate VT278 Click image for larger view.
The DECmate VT278 is a PDP 8 on a CPU / RAM board installed in a VT-100 chassis. Pictured here is the SETUP screen one sees upon successful boot. Click image for larger view.
This image shows the CPU card (left) and Comm port card (right side). Click image for larger view.
These are the RAM modules. Note that the rear RAM module was found to be defective and removed. The system should have 32K, I guess removing one RAM module will reduce to 28K, I have not determined yet, but the system will boot without the last RAM module installed. Click image for larger view.
Here is a close up of the RAM module removed from the CPU card. Note the missing pin. Click image for larger view.
After removing the bad RAM I was able to access terminal mode by pressing "4" from the SETUP screen. Click image for larger view.
This is the dual RX02 drive pedestal that came with the DECmate. I need to get cables and software. I don't know if the drives work. Click image for larger view.
I happen to have a 37pin to 25 pin cable that was used in a DEC environment, but it was split to connect to two "somethings" so I will need to check the pinouts from the manual and compare with the cable, hack it to work as a DECmate cable.
