I have a recently new to me M200, and a couple M100s. The working M100s have 32K of RAM, while the M200 has 72K of RAM, in 3 banks of 24K each.
I was surprised to learn that apparently the maximum amount of usable ram at one time on an M200 is under 20KB, even though is has more than twice the memory of the M100. There are some basic programs I'm interested in running on the M200 that take up more than 20K of memory, are there any workarounds or alternate ROMs that have a larger linear ram address space? I guess maybe the REXCPM will have a contiguous 64K or RAM address space on an M200? I'm mildly surprised that Tandy would have made an "upgrade" to the M100 that even with more total memory could not run as large a program as the M100.
