The Tandy Model 4 runs an excellent, totally compatible version of
CP/M 2.2 from a company called Monezeuma Micro. The specifications
are as follows: TPA on 64k system 56,070 bytes; 55046 bytes with
a hard disk driver installed. CP/M IOBYTE: fully implemented.
Device drivers: 35, 40, 77 & 80 track, single/double density,
single/double sided, 3.5, 5.25, or 8 inch, more than 85 formats
supported. Maximum disk capacity: 40TK SSDD = 220k; 40TK DSDD = 440k;
80TK DSDD = 880k. RS-232: All word lenghts, parity & baud rates.
Parallel Printer: With/without line and/or form feeds. Video: 24x80
with reverse video. Keyboard: full ASCII with 9 function keys.
RAM disk: 64k, *AUTOMATIC* on 128k systems.
Montezeuma Micro's numbers are (214)-631-7900 for information,
(800)-527-0347 for ORDERS ONLY. If you want more info, pick up
any issue of 80 Micro magazine.
Note that the Model 4 comes with an excellent OS called TRSDOS 6.
There is a lot of excellent software available, and even if CP/M is
your primary interest, don't ignore this capacity of the machine.
Pro-MRAS is *the* best Z-80 assembler I've seen, and with a utility
like HyperCross, you could develop CP/M software under TRSDOS, if
you wanted to. If you want more info, don't hesitate to ask me
directly.
An Eminently Satisfied Model 4 User,
