- WE LOOKED INTO THE FUTURE...AND IT WAS MURKY
- by John Goldie, BOSKUG, June/July 1987
-
- (A conference discussion on CP/M.)
-
- There is an opinion that suggests the Kaypro 2, 4, 10, 1, or 2X
- you've grown to know so well might be the end of the line for
- CP/M machines. On the other hand another opinion holds that,
- with a little tweaking here, and a new board there, you may be
- able to upgrade your old computer into a 80286-80386 class
- machine, addressing 16 megabytes of memory, and rampaging along
- at 12 MHz.
-
- A panel discussion of CP/M aficionados discussed the past,
- present, and future of the venerable operating system at June's
- BOSKUG meeting. The discussion, held in conjunction with the
- BCS's CP/M, Commodore, and Osborne groups, really didn't resolve
- anything definitive about the future of CP/M, but it did suggest
- that there are widely divergent views on the future viability of
- eight bit computers.
-
- The participants were Karl Radov of the Osborne group; Bob Freed
- of BOSKUG; Gerry Buzzell of the Commodore group and Jim Byram and
- Jay Sage, past and present directors of the CP/M group.
-
- THE HISTORY
-
- The way Jim Byram tells it, Gary Kildall, the author of CP/M,
- left Intel because the company did not want to develop an
- operating system. In 1976 Kidall's new company Digital Research
- developed CP/M, version 1.3. The operating system was extremely
- buggy and it was followed by versions 2.0 and 2.1. Byram says
- 2.0 "was a minefield," and that "2.1 came and went in a matter of
- weeks." Version 2.2, the version most of us are familiar with,
- arrived in 1979.
-
- The limitations of CP/M were manifold and public domain programs
- developed rapidly to extend the utility of the operating system.
- As the microcomputer community grew, public domain programs were
- widely distributed along with the original source code and a
- standing invitation to tinker with the programs and make them
- better. The cooperative spirit that characterized the eight bit
- world was a natural survival technique in microcomputing's
- pioneering era; it is rare in the more competitive MS-DOS arena.
- Two things were reiterated throughout the evening. One was the
- cooperative nature of CP/M public domain programmers. The other
- was the fun and approachability of the CP/M operating system.
-
- THE FUTURE
-
- Karl Radov was pessimistic. He feels that CP/M will eventually
- wither because computer users are less often hobbyists and more
- frequently business users. These new users employ complex
- application programs and depend on seamless interfaces that
- insulate them from the operating system, in which they have no
- interest. In addition, marketing forces, by concentrating on MS-
- DOS and Macintosh environments, have inexorably elbowed CP/M
- computers out of the mainstream.
-
- Jay Sage, on the other hand, was less inclined to concede the
- passing of CP/M. Citing figures of 5000 CP/M computers per month
- for Ampro's Little Board computers, Sage suggests CP/M sales are
- holding their own, especially for industrial applications. New
- and innovative microprocessors like the Hitachi 64180 and the
- recently released (but four years late) Zilog Z280 loom
- tantalizingly on the horizon. These microprocessors are capable
- of propelling CP/M computers far beyond their current
- limitations.
-
- For example, High Tech Research (1135 Pine Street #107, Redding,
- CA 96001, 800-446-3220) has announced their Ultraboard, a Z280
- replacement of the Kaypro's Z80 chip. The company claims that it
- will run anything that can run on the Z80, but at 12 MHz (and
- will sell for under $500). In software, Sage reports that ZCPR
- is evolving toward a Z Operating System (ZOS), capable of taking
- advantage of such hardware.
-
- Still, some aspects are undeniably discouraging. Most panelists
- agreed that few new commercial programs, with the exception of
- WordStar 4, are being written for CP/M based computers. Despite
- their technological advances, the new eight bit microprocessors
- may have arrived too late, and acceptance of them may depend more
- upon marketplace forces than upon their computing excellence.
- The more fervent panelists stressed, however, that the hacker
- intensity is still alive. Figuring that this intensity was a
- main factor in building the CP/M world, they suggest a similar
- commitment might be sufficient to keep it afloat long enough to
- begin taking advantage of the new chips. After that, who knows--
- stay tuned.
