Who said that C64 aren’t useful anymore ? For what we know they could be still used inside nuclear silos but we just get enough knowing that they are still used in..

>Making backups of old turbo-tapes to disk and notice that the quality was very poor on some tapes. So have a LOAD-IT datasette with a signal meter. Problem with it was, that You could turn the knob (head alignment) 45 degrees and still have same two(lousy) bars on the meter. There was a need for something more accurate when adjusting the alignment to get the best signal while reading the tapes.

C64 Vic 20 Hardware Repair


Defects found on the Commodore VIC-20:

  • Error message (device not present) when trying to access the IEC devices, like a Floppy Drive.

Defects found on the Commodore 64:

  • Black screen of death after installing the missing roms.

The repair of the Commodore VIC-20 was made by replacing a HEX Inverter Buffer 7406.

The repair of the Commodore C64 was made by replacing the MOS 906114-01 (PLA – Programmable Logic Array).

Amiga Minimig


AMIGA Minimig (short for Mini Amiga) is an open source re-implementation of an Amiga 500 using a field-programmable gate array (FPGA).

Minimig started in secrecy around January 2005 as a proof of concept by Dutch electrical engineer Dennis van Weeren. He intended Minimig as the answer to the ongoing discussions within the Amiga community on implementing the Amiga custom chipset using an FPGA. The project’s source code and schematics were released under version 3 of the GNU General Public Licence on 25 July 2007.

The original Minimig prototype is based on the Xilinx Spartan-3 Starter Kit, the Original Amiga Chipset is synthesized in the FPGA. Two printed circuit boards are attached via the FPGA kit expansion ports. The first one holds a 3.3V Motorola 68000 type CPU. The second has a MultiMediaCard slot with a small PIC microcontroller acting as a disc controller that supports the FAT16 filesystem and does on-the-fly Amiga disk file (ADF) decoding.
