Not quite sure where to post this - but I will try here in Hardware.
I have just got hold of a Wyse WY120 terminal for use with my Z80 project which is under development. It is a general purpose terminal from the late 80s. The WY120 was the European version of the WY150.
Trouble is, the poor thing isn't well - I just hope it isn't terminal
Upon switch on, the terminal just emits a continuous bleep - the caps lock, scroll lock and num lock keys are all lit and do not go out (as I would expect them to do).
The service manual isn't too forth coming - all of the power on diagnostic routines assume that the terminal starts up. I have checked the clock frequency on the 8032 and all seems well. The power supply - at least the 5v for the 8032 is good and the CRT itself appears to be working correctly.
Does anybody out there have any experience of terminals? Is there anything else I should be looking at?
