I have a machine that hasn't been powered in years. Powered up first time yesterday. Fully bots up floppy works.
With the 16k card plugged into the memory socket the display is garbled. You can see where characters are supposed to be but unreadable. Disk boots still.. Without the 16k it boots cleanly 95% of the time but still gives me that messed display once in a while. So i don't think it is 100% the 16k card but noise or something. I have a tested card coming from ebay next month. I pulled the ram chips out of the 16k card same result. I have swapped most of the 74ls chips on it same result.
Also the keyboard seems to need a good cleaning. Some keys repeat, others need to be hit 5x to get it to register. Any good suggestion on how not to mess it up more?
