Different Flash memory adapters for Commodore/Amiga or other classic computers/devices.
For now there are following types of the FlashROM:
- 40pin to be used in Amiga 500.
- 42 pin designed for my Amiga 1200 but also can be used in A500 rev 8 mainboard.
- 24 pin for Commodore 64 computers. Replacement for 2316/2332/2364 ROM chips.
Schematics/BOM and Gerbers located in each ones folder.

42 pin x2 in A1200
24 pin, KERNAL, CHAR, BASIC ROMs replacement in Commodore C64
An adapter for TL866 to program the flash memory. It based on the circuit: https://proghq.org/wiki/index.php/TL866_TSOP48_adapter Circuit diagram, gerbers and ATtiny firmware are in "FlashAdapter" folder.
Four wires required to be connected between the adapter and 40pin FlashROM(as shown below): A18, #BSY, #RST and #WE. For 42pin FlashROM, only needed #BSY, #RST and #WE as A18 and A19 already connected via socket's pins 1 and 2.
