Recently got a 5150 from Craigslist for a good price. -VIDEO-
Long story short, I decided to work on the keyboard first. No point in anything else unless you can type. I was hoping to just re-attach the space bar and it would work fine afterwards. Sadly that did not correct the issue. The system is acting as if there is a key being held down constantly. I had to completely tear down the keyboard to properly reconnect the space bar. Which went fine. The foam inside is acceptable in condition. The problem remains.
I felt I would pick the brains of the people here before I sank money into something that might not work.
1 - keyboard acts like a key is stuck down. The system will boot into dos/basic and constantly beep until it crashes.
2 - Using just the PCB, the errors remain.
3 - I currently do not have another keyboard compatible with the 5150.
4 - There are no visible issues with the electronics.
This would explain why the previous owner scrawled BAD over the top of the keyboard. (which I removed) I don't want to lead the witness here, but after some internet searching I've come to the conclusion there is an issue with the electronics.
Any advice on how to proceed?
Side note: I'm going to work on building a XT-PS2 adapter just to get things working. (8051 based - its what I have)
