They may have acquired Topspeed / JPI M2, but those were for the Intel PC
environment. The product I'm referring to was specific for Z80 CP/M and
never appeared in a PC flavor. It compiled to "M-Code" and linked in the
runtime engine. Programs may have run somewhat slower than the output
from a true native compiler but the intermediate code was very compact
and, I believe, relocatable. My application had a lot of hardware
interface requirements and TM2 supported modules written in Z80 assembler
for bit-tickling. There was even a special version written to take
advantage of Zilog Z180 / Hitachi 64180 memory mapping. That variant
supported an extended address space (up to almost 1 MB) for executable
code (though not data).
Turbo Modula-2 was marketed through a third party, but had Borland's name
on it. Odd arrangement, but it was definitely their product.
