Restoring & Repair a Commodore 8296 (TAN Case)
The conditions of this Commodore 8296 (TAN Case) are really bad. The CBM 8296 is left for over 25 years in a dovecote.
The cleaning, repairing and restoration have taken a very long time, but the result is more than acceptable.
Defects:
- The Commodore 8296 was completely dead (Black screen of death).
- Little problems of CRT geometry.
Replaced parts:
- Replaced PLA U6 with a OTP EPROM 27C512R 70ns + Adapter
- Replaced the ROM 2 x 2764 Eprom with 1 x 27C128 Eprom (spare parts from a original cbm pcb)
Note:
I have replaced the original ROM (2 x EPROM) pcb because the PLA adapter is fat. I could insert a small castle (photo) between the ROM pcb and the Main Motherboard but in this time i have prefered to replace with a single Eprom.
