Description
This is a simple 32KROM and 32KRAM memory card. There should be place enough, so that the ROM can be put into a ZIL-socket. The ROM socket has been designed for an EEPROM ROM Project cloned from "Marten Feldtmann" Upgrading to 4-layer board. REVISION: 2.0 Design finished 18th November 2020 Marten and everybody else, hopefully you like this upgraded version so much that you could order this from JLCPCB. Current price for 5pcs: $38 + shipping
