jens-eike Posted July 22, 2020 Share Posted July 22, 2020 I used the board to make a GRAM-device (like GRAM-Kracker) with battery backup and logic for bank switching the >6000 ROM XB-style. The two stacked NEC D43256 are the GRAM, two 6264 (below the leaked battery) are the ROM (when write protected). 8 1 Quote Link to comment Share on other sites More sharing options...
Hans23 Posted March 13, 2021 Share Posted March 13, 2021 (edited) Hey, I was given a collection of homebrew TI hardware that smells 1980ies DIY all over and that I don't really want to keep. If anyone's interested in these things, they're free if you pay postage. Here's what I have: Some EPROM card - The EPROM contains unknown-ti-rom.BIN. Some I/O interface? Looks like an EPROM programmer for the cartridge port. A H.Martin module with 32K SRAM fitted - There is a stack of the 8K RAMs to the right.

+Ksarul Posted March 13, 2021 Share Posted March 13, 2021 That weird I/O interface thing looks like it might be a RAM tester of some kind, based on the horde of LEDs at the top of the card. . . The EPROM programmer looks like it might be one from either the TI Revue or 99-Journal. ISTR that both of them published plans for Eprommers. . .with layouts. I think there might have been one in CK too. 1 Quote Link to comment Share on other sites More sharing options...
