I ran the repair of the membrane that had a micro interruption, i have used a micro-drop of vinilic glue mixed with the graphite that i have scraped from the pencil ikea, i made a thin film on the microfracture and now it works.
There were other problems, including: graphite consumed in some keys and the keyboard connector (pcb side) don’t work very well.
I have received this motherboard of a CBM 8032 to repair from Rossano T.
The motherboard was devastated by rust, many components are short-circuited due to rust that was abundant on the pins side of the chip. Unfortunately the computer was turned on to test it, causing the total breakdown of more components.
I have installed 40 socket because some components are rusty other are dead, however some traces under the chips are eaten by rust and and i had to rebuild.
The repair and cleaning took me a very long time and a lot of patience, it took me about 10+ hours.
Components Replaced:
- 1 x 4650 (6845P) CRT Controller
- 3 x 4116 RAM
- 2 x 2114 Video RAM
- 5 x 74LS244
- 3 x 74LS74
- 1 x 74LS02
- 1 x 1uf 100v Capacitor
Phases of the repair:

Regenerator is an interactive disassembler for C64 binaries. Regenerator will load any standard C64 .PRG file (or VICE snapshot) and disassemble it for your convenience.
There are a few options you can choose to change the output and a few tools to make the output look better and more useful to programmers. Regenerator runs under M$ windows and need .net 3.5 (or 4.0) runtime.
New in version 1.3:
- Added REMOVE command to remove part of the data from dissasembly.
- Added EDIT BLOCKS window to Edit all the DATA, TEXT and REMOVED blocks manually.
- Added COPY to Clipboard functionality (insert key) with FULL or CODE only modes.
- Added possibility to add user-defined COMMENTS to the code. This can be done as a FULL line comment or as a SIDE comment!
- Added USER LABELS – you can now add a label to any address and it will be used in the disasembly. If there should be an automatic label generated for it then it will be overriden. Also added USER LABELS editor which is part of the old Label Prefixes window. You can add/edit and remove user labels within this screen and have a general overview of the user labels.
- Added high and low partial references to immediate opcodes. This means that code like LDX #$A0 STX smwhr LDX #$BB STX smwhr+1 will be disasembled as LDX #<pBBA0 STX smwhr LDX #>address STX smwhr+1. This includes loads and stores in different order and with different registers. There is also a context menu command that lets you disable this on a currently selected address (if auto creation fails). NOTE: excluded address in STA opcodes will not be generated like this!
- Fixed the Add BLANK LINE and Remove BLANK LINE so it actually works as it should.

The failure was due to a cold solder on the ram socket and a bent pin on the ic MOS 8276.
