Repair Luxor ABC 80 *updated*
Defects:
- Some keyboard keys are totally dead.
- Missing +17v and obviously the +12v
- Short-circuit on the psu side, inside the monitor.
- Tape Recorder with the mechanism stucked.
Repairing:
- Replaced most of the Tantalum Capacitors* on the main pcb and on the tape recorder pcb, some are in short-circuit.
- Replaced 1 x Fuse on the CRT Monitor pcb side.
- Repair Tape Recorder, i had to disassemble most parts of the tape recorder mechanism. The lubricant grease was dry and has totally blocked the mechanism of the tape recorder.
- Replaced all pads (Foam Mylar Pad) of the Keytronics Keyboard, the same Keyboard used in SOL-20.
* For this repair i have used only tantalum capacitors, although i usually prefer to use electrolytic capacitors, i used to keep the same aesthetic.

Hi!
Is it possible to get a dump of the keyboard controller MCU (30293B-01E @ Z6) ? It should be dumpable as an Intel 8048.
