***Note***: The SST39SF010A in the tssop package is no longer in production. You can still get them aftermarket, but please consider this when ordering with assembly service...

There is a new version of this board, with a chip that is still in production. The link to the version 2 board is here:

https://www.pcbway.com/project/shareproject/Version_2_2364_2332_2316_Universal_Re_Programmable_Replacement_ROM_c2f82c1c.html

This board uses the TSOP-32 SST39SF010A 1Mbit flash ROM and can replace a 2364, 2332, or 2316 mask ROM. It uses a separate adapter PCB to allow programming/re-programming as a DIP-32 SST39SF010A. Configuring the board for different chip types and/or active high/low chip select pins is done through solder jumpers on the board.

You can also use the labeled, higher address(A13, A14, A15, A16) lines to do ROM switching.

This board has been confirmed working in the Commodore 64 Kernel, Basic, and Character ROMs. The Commodore VIC-20 Character, Kernel, and Basic ROMs. The TRS-80 Model 4 2316 "ROM C". And to replace the ROM chip in the ATARI 2600 cartridges.
