STM32 (Arm Cortex MCUs) SID Player by Bakisha.
SID chip (6581 and 8580) and 6502 CPU emulator for STM32 (Arm Cortex MCUs). Compiled with Arduino IDE and uploaded with ST-LINK V2.
NOTE:
I have added to the original code of Bakisha the visualization of the 3 SID voices via 3 x Green LED.
Useless to write more about this, watch the video and the photos.
Special thanks goes to Bakisha for his work.

- 1 x BreadBoard.
- 1 x STM32F401CCU6 (STM32 Black Pill) or STM32F407VET6
- 18 x BreadBoard jumper.
- 1 x SD Card Module.
- 3 x Green LED.
- 1 x Resistor (100 Ohm)
- 1 x Capacitor (100 nF)
- 1 x Capacitor (10 uF – 16v)

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.

A new firmware update for the ARM2SiD/ARMSID has been released by Nobomi.
ARM2SID firmware 3.12:
- Digifix in MOS8580 emulation is now configurable. By the software it can be set to a several levels including inverse polarities.
- The Digifix is controlled by external pin current by default (as a real MOS6581 is). If you miss it, just set it by the configuration program as you want.
- Digifix for MOS8580 is required for example in the Ghostbusters game, but most of the games, demos and music (specially new ones) is not counting with Digifix and can produce some additional noises and hum.
- In this FW is finished the hotfix in noise generation (test bit) from previous FW, now is no sound missing for example in the TestBit_4x.sid.
- Big improvement in 6581 emulation. Fixed inner analog offsets in the MOS6581 emulation. Less distortion in some demos (for example Mahoney – Musik Run/Stop) and no more clicks in some games music (for example Bubble Bobble).
- Fix in tone counter updates during fast changes.
- Fixed setting of the lowest filter frequency for MOS6581 emulation (sometimes the simulation did not match the settings).
ARMSID firmware 2.12:
- Fixed setting of the lowest filter frequency for MOS6581 emulation (sometimes the simulation did not match the settings).
- Remember the “Digifix” update from the previous version, if something sounds different to you on the MOS8580 emulation, please check the configuration.
Previous changelog of ARMSID firmware 2.11:
- Digifix in MOS8580 emulation is now configurable. It can be set to few levels including inverse polarities.
- Digifix is now controlled by external pin by default (as a real SID is). You can change it in config utility.
- Digifix for MOS8580 is required for example in the Ghostbusters game, but most of the games, demos and music (especially new ones) do not expect Digifix and can produce some additional noise and hum.
- Improved noise generation (test bit) from previous FW, no sound missing for example in the TestBit_4x.sid.
- Fixed inner analog offsets in the MOS6581 emulation. Less distortion and no more clicks in some music.
- A small fix in tone counters updates in the fast changes.
- Faster release of the data bus after reading cycle.

Dirty and Ruined Intellivision *Black Screen* repair.
It would not have been nice to put the intellivision in a very worn state and without a controller inside the spare parts box without even trying it :-)
Obviously the intellivision was not working, black screen.
The repair was simple, i have replaced the AM9114 (U8-B) RAM with a NEC 2114 and everything started working better than before :-)
I have also removed both labels in a pitiful conditions, now it looks better than before.

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.
