Autopsy:

They are completely applicable to IBM PC/XT/AT/386/486 compatible computers and need no any special interface cards.

This is a Commodore CBM 8296-D Motherboard repaired for a Friend.

Gallery of the repair:

Defect:

• Black screen of death without startup beep and after replacing U5 and U6 black screen of death with startup beep.

Replaced parts:

• Replaced PLA U5 with a original PLA MOS 324745-01.
• Replaced PLA U6 with a OTP EPROM 27C512R 70ns + Adapter
• Replaced a dual FlipFlop 74LS74 UD4.

* The replacement of the two PLA has already been made earlier by my friend.

The conditions of this Commodore 8032-SK (Gold Label) are really bad. The CBM 8032-SK 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 8032-SK was completely dead (Black screen of death).
• Little problems of CRT geometry.

Repair:

• Replaced the CPU 6502.
• Yoke calibration of the CRT

The aim of this project is to replace the floppy disk drive by an electronic device emulating the floppy disk drive (list of supported Computer/Hardware).

There are two differents emulators:

• A USB version which allows to connect the floppy disk drive interface of the computer to a PC via a USB cable.
