REX2 - custom REX for CP/M support
REX2 is now available. In addition to the 1MB of flash, it also provides 128 kbytes of SRAM. This SRAM is included to allow for an all-RAM mode of operation, for CP/M support. This activity is being done in conjuction with the development of Model T CP/M, via the MTCPM mailing list.
Please see the MTCPM page in the wiki for information on REX2, since it is planned for use in MTCPM only.
