I've had this minty-fresh pristine machine in my closet for a few years. Had a garbage character screen when I found it.
I have it booting to a 'Ready' prompt after a Z80 replacement. I can type in a basic program and it will run. Mostly. it sometimes a acts flaky and will reset the screen when I hit return. Seems to reset after a period and loses whatever basic I had typed in.
I'm pretty sure one of the RAM chips is bad, as it is FIRE HOT.
I want to keep this machine as stock as possible at 4k/L1.
Questions:
1. the RAM is Motorola 3108003. I'm assuming the 8x of these is 4k? ?MEM just gives a WHAT? reply. Level 1 didn't have a ?MEM function?
2. What is a replacement part number/source for these DRAM chip?
3. what are the shunt setting options for Z3? can't find a reference on this. it works as-is, just curious.
Thank you
