REX2 - custom REX for CP/M support
REX2 exists in very limited quantities. It is an experimental device only, for development of CP/M applications.
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.
It is not currently available for sale, however this may be reviewed if CP/M use on M100 becomes real.
Please see MTCPM.
