Locally bought rusted Displaywriter set without keyboard (unit / monitor / floppy drive). As no signs of life then decided to find another working unit and do inspections.
Found nice set in germany with keyboard and printer. Also got extra set but based on 110V.
Then having 3 sets I could do some tests...
Here is log, maybe someone more experienced will share with his thoughts, before will do assembling back:
Set1: bought locally. Unit + Monitor + Floppy drive. 220V
- motherboard: NOT WORK
- video card: once booted with solid background, later anymore
- memory card: 224KB. OK
- extended memory card: 64KB. OK
- floppy. 2x double sided. Noisy but works
- monitor: ok
- PSU: `A` LED
Set2: Unit + Monitor + Keyboard + Floppy drive. 220v
- memory card: 256KB. OK
- comm card (long), extra purpose? difference between short/half version?
- video card: ok
- motherboard: ok
- monitor: ok
- floppy: single sided + double sided. Silently works
Set3: Unit + Monitor + Floppy drive. 110v
- memory card: 256KB
- comm card (short) ?
- video card: ok
- monitor: ok
- motherboard: ok
- floppy. 2x single sided. Silently NOT WORK. No reaction after inserting disk
Printer. I pushed Print Test then caret moved to the left and center. After that something cracked and smoked...
Extended memory card I upgraded from 64KB (2x32) to 160KB (5x32) and setting (removing) jumpers. Then DW boots and reports 416KB memory.
So from local rusty unit I found valuable? extender memory card and had donor memories from main card.
