falcon needs help

[danwinslow]

I have been working on re-assembling a Falcon recently. It worked at one point, but later when I went back to do some more it now seems to have trouble generating a video signal. Here's a picture of what I get. It has nothing in it but a known working 14MB Wizztronics board and the power supply. That's it. Keyboard, internal floppy and hd all disconnected. Any ideas? Tried a few different monitors, som esaid "out of range", some showed this same pic. For all I know, the VGA adapter plug has gone bad but I doubt it.

Additional info - with a CTE63 installed, the CT63 seems to operate normally. When I jumper it for 030 mode, then the results are the same as above. Could this possibly be a battery issue?

Well if it is anything like other STs it won't work without the keyboard (the IKBD chip is used by the system), so you might want to stick that back in first

 

If that doesn't work then the NVRAM battery dead issue is likely to be the cause of the issue. Try resetting it as a first port of call.
