GW-48Z02-1 Module Repair Board

For sale are new Glitch Works GW-48Z02-1 NVRAM repair modules. These modules are used to replace the entire CAPHAT assembly on a dead Mostek/ST MK48Z02 NVRAM. This listing is for the assembled repair board and CR1225 battery, as seen in the first picture. The second picture illustrates the module installed on a recycled MK48Z02 NVRAM, but the NVRAM IC is not included in the listing.

These modules will work on a number of Mostek/ST 24-pin clock/NVRAM ICs, but were designed for MK48Z02s. You can find installation instructions and read about their development on our site. (the link is for the GW-48T02-1, which is very similar to the GW-48Z02-1)
