Digital Research now offers CP/M, a
low-cost advanced disk operating system designed for use with
IBM-compatible diskette-based computer systems which employ the Intel
8080 microcomputer. Previously available only to OEMs, CP/M has been
in existence for over three years in various manufacturers' products
and has undergone extensive field testing. The functions of this
software package include named dynamic files, program editing,
assembly, debugging, batch processing, and instantaneous program
loading, resulting in facilities similar to popular timesharing
services. CP/M is an "unbundled" software package, which can be easily
adapted to any 8080 or Z-80 computer system with at least 16K of main
memory and one or two IBM-compatible disk drives. Although the
standard CP/M system operates on an Intel MDS, the fieldmodification
manual provided with CP/M tells how to alter CP/M for other hardware
configurations. Price for a complete CP/M system in object form with
documentation is $70, documentation (set of 6 manuals) alone is $25.

6502 Resident Assembler,
Tiny BASIC Interpretive
Programs on ROM
Microcomputer Associates Inc.
announce their 6502 Resident Assembler Program (RAP) and Tiny BASIC
interpretive program on ROM chips. Two 2K x 8 ROMs comprise the
software ROM package housing the 1 .75 K Resident Assembler and the
2.2K Tiny BASIC program.
Formerly contained in seven
1702A PROMS, RAP is the only single pass Resident 6502 assembler
available today. Statements are entered either from paper tape or
directly from a terminal keyboard. RAP generates a listing and places
object code into RAM for immediate execution. A minimum of 4K x 8 RAM
memory is needed with the users' 6502 microcomputer. RAP allows a 6502
microcomputer to function economically as a microcomputer development
system. Following assembly the programs can be debugged using the
debugging facilities of DEMON, Microcomputer Associates' DE-bug
MONitor program housed in the 1 K ROM section of a 6530
ROM/RAM-1/0-interval timer circuit. A text editor is included.
The ROMs are totally
pin-compatible with 2708-type PROMs.
The RAP/Tiny BASIC ROM package
(SW 101) is priced at $200 and includes full documentation with
deliveries from stock to 30 days ARO.
RAP is also available on a set of seven 1702A
(SW200) for $295. Tiny BASIC is
available either in paper tape format (SW300) for $25 or on a set of
nine 1702A PROMs (SW201) for $275. All software is fully documented
with deliveries from stock to 30 days ARO.
