A person in need of my help of which i have already repaired several devices has contacted me and asked if i could make a repair of one of his Commodore PET with two different trouble.
- The first fault was black screen on power up, meaning no image was displayed.
- The second fault that occurred after a couple of days was a raster video distortion of the CRT monitor accompanied by a smell of burning (see photo)
The first fault was solved by replacing the UD7 ROM (901465-02) with an eprom (2532), the correct functioning test could be done by connecting the LCD monitor that i use for repairs via a video adapter.
The second fault was brilliantly resolved by replacing the voltage regulator installed on the pcb monitor, a 7812 which on the pin output did not always return 12v but rather a mix between 3v, 6v, 10v.
I also removed some pieces of foam rubber (see photo) which due to the glue used has damaged the back of the monitor PCB leaving obvious traces of corrosion and a black sticky stain that i have removed.
I also rebuilt a missing pin of the ROM UF14 (901447-10) that someone had thought to fix in a very rough way (see photo)

The UnoCart is an Atari 2600 cartridge emulator at low price and open source under a GPL license. It supports cartridges with up to 64k of ROM and 32k of RAM with extensions; BIN, ROM or A26.
It comes with a 3D printed case and it works on PAL & NTSC systems! It will also run on most 7800 machines (but will not run 7800 ROMs).
Most games and demos, including Pitfall II, runs fine on 99% of systems. The firmware has been updated, we are on version 17 released in September 2020 to maker sure of maximum compatibility.
Recent homebrew releases, like Galaga, The End and some others that require DPC or DPC+ commands will not work yet.

What is DiagROM?
DiagROM is a diagnostic tool for the amiga computers.
And it is to be used on defective machines, trying to help no-boot situations etc.
You simply replace the Kickstart roms in the Amiga with the DiagROM. and when poweron. your Amiga will start a diagnostic software. It will try to dump info on the serialport (and actual menus etc aswell) while also trying on the screen.
Changelog:
WOW This is a long time since I updated this. And lets be honest. I have forgot what i have changed.
BUT one thing I just been thinking. I have bumped the versionnumber in the wrong “end”.. so as I am working on a new init-routine. I consider this is the “stable” one.
So I bump the serialnumber to 1.2.1. I have been too busy with hardware so I must confess I haven’t coded so much on DiagROM. I have made some minor bugfixes etc.
I must still warn that if a routine is experimental you cannot really trust the tests.
Anyway in hope for the best in the future. the “daily” will for a while be a little “jumpy” while I get the new init working. This should be useful meanwhile.
