If you wish to use this adapter for reading 82S129s rather than replacing them, flip the adapter over and solder together pins #13 and #14 of the 16 pin socket as shown below NOTE there is an error in the newer model of this adapter and reading 82S129's is broken, it can be easily fixed. Read the chip in a EPROM programmer as a 27512. Then insert the original 82S129/82S131 in the socket.

Instead of installing a 28 pin socket, install 2 x 12 pin headers. Then instead of installing 2 x 8 pin terminal strips, instead install a 16 pin socket. (you cannot read off of a 82S126 without external electronics) Simply set the correct solder jumpers. These can also be used to read data off of existing 82S129/82S131s. However I CANNOT guarantee they will work for your specific use.ģ/4" tall (including height of a WC27512 inserted into the socket, including length of adapter legs)
The EPROMS included with the EEPROM options the (Winbond 27C512-45) are VERY fast and have worked in my limited tests (galaga, millipede, and crystal castles, food fight to date).

Whenever I needed one I needed to use a outside source and it was expensive to get. These bi-polar PROMS were made in the 70s and VERY hard to find, and VERY expensive and the most of normal in-expensive programmers will not even program them. I created this kit as I work on a lot of early 80s arcade games, every once in a while I need to replace a 82S129 or 82S131 bi-polar PROM. This kit is a very small adapter board that can take a cheap and easy to find W27C512 EEPROM and replace 82S129 or 82S131 bi-polar PROMS. The 82S129-82S131-to-27512 is a universal replacement solution to replace 82S129 or 82S131 bi-polar PROMS with newer easy to find fast EEPROMs.
