Sorry, no REX# does not include the function to replace the main ROM. How I would tackle a custom ROM in the M100 * develop in inside Virtual T * get a socket adapter PCB for a 27C256 EPROM, or better still use an EEPROM * once you have a prototype in VT, burn it and install in the M100
Maybe FlexROM helps? is it a better way to get the ROM swapped? I don't know much about it. ...Steve On Sun, Nov 12, 2023 at 5:10 PM runrin <run....@rin.run> wrote: > Hi all, > > I've got a REX# in my m100 and was wondering if it was compatible with > the FlexROM, which I see uses some jumper cables to interface with the > original REX.
