- ANY SIGNS OF LIFE?
-
- How healthy is CP/M? If you look at the major magazines or listen to
- people like Adam Osborne, the answer is simple. CP/M is dead. Embalmed.
- Headstone overthrown, graveyard choked with weeds.
-
- And hearing that, you can be forgiven for thinking of turning to IBM.
- We all want to get the most out of our computers, to keep doing more and
- more with them, but how much time and money is it worth pouring into a
- machine that has been written off? Shouldn't you switch your efforts to a
- computer that has a future?
-
- Rather than organizing a wake, or, alternatively, jumping up and down
- screaming "CP/M is _not_ dead" ("Is too." "Is not."), let's see if we can
- figure out what's really going on.
-
-
- [HOW MANY USERS?]
-
- Everyone assumes, without getting specific, that CP/M machines hold an
- insignificant share of the "installed base" of computers compared to that
- held by IBM and IBM-compatible machines. But InfoCorp quoted in _Profiles_
- magazine (September 1985) estimates that at the end of 1984, 1.7 million
- CP/M computers had been sold versus 2.85 million IBM and IBM-compatibles.
- What's more, the CP/M numbers don't include Apple computers running CP/M,
- generally acknowledged to be a larger share of the CP/M market than any
- other single machine.
-
- These figures are now almost a year out of date, so considering all
- the CP/M Apples and the CP/M computers sold in the last year, it's not out
- of hand to suggest that the CP/M user base may be 2.25 million. The IBM
- and IBM-compatible computers have outstripped this, of course, and will do
- so at an increasing rate (until they're run over by something newer). All
- the same, at a time when hardware and software companies are searching for
- "niche markets" in order to survive, a base of 2.25 million CP/M users is a
- substantial niche.
-
-
- [HOW MUCH PERFORMANCE?]
-
- The IBM and its clones have two major advantages over CP/M in
- performance. The first is graphics--I don't expect to see much in the way
- of graphics on CP/M computers because they have no standard hardware. The
- second advantage is memory space. IBMs can use up to 640K of RAM (random
- access memory), or even more with the new Lotus/Intel memory management
- scheme, for running massive programs like Framework or building monster
- spreadsheets. CP/M computers can only use 64K (except through bank-
- switching, which has never caught on).
-
- In basic, workaday computing, however, CP/M not only holds its own
- against IBM but often comes out ahead. Consider the Kaypro--not the
- fastest CP/M computer by any means. If you use WordStar on a Kaypro and
- then on an IBM, you'll find that it runs much better on the CP/M machine.
- On the IBM, it feels sluggish, especially when rewriting or scrolling the
- screen.
-
- And don't let anyone tell you that it's because the IBM WordStar is a
- dog. In their August 20 issue, _PC_ magazine ran all the major IBM word
- processors through nine word-processing tasks. They remarked, "On the nine
- benchmark tasks, WordStar Professional gave perhaps the smoothest
- performance of any program except XyWrite II-Plus and Textra, consistently
- taking less time and fewer keystrokes than most of the other programs."
-
- Or try comparing dBase II on a Kaypro and an IBM. In his _Advanced
- dBase II User's guide_, Adam Green ran four dBase II tests involving
- sorting, indexing, and displaying mailing lists of various sizes. On the
- average, the Kaypro completed these tests in half the time it took the IBM.
- (Yes, I was a bit taken aback, too, but go look it up yourself. Better
- yet, try it yourself.)
-
-
- [HOW MUCH ACTION?]
-
- Along with user base and performance, a third measure of health is the
- number hardware and software products available. It's hard to judge this
- activity in the case of CP/M, because CP/M products get little (if any)
- editorial or ad space outside of a few magazines like _Profiles_ or _Micro
- Cornucopia_. How many CP/M reviews have there been in _InfoWorld_ in the
- last year? And how many CP/M-oriented ads in _Byte_?
-
- Without such ads and reviews, it's almost impossible for the average
- CP/M user to know what's available or even what _might_ be available. All
- the same, there's some interesting stuff going on. Though the industry
- heavyweights have abandoned CP/M, their places are being taken by small but
- active companies like Spectre Technologies, Westwind Computer, and Xpert
- Software. More than anything, it reminds me of the mini-industry that
- developed around the VW bug after Volkswagen stopped manufacturing it.
-
- [HARDWARE] One of the biggest pieces of news is the release of a new
- high performance 8-bit CPU chip, the Hitachi HD64180. This chip is "upward
- compatible" with the Z80 chip usually used in CP/M machines, meaning it can
- run all Z80 instructions plus some of its own. The HD64180 runs at 6MHz
- (9MHz before long, they say), contains a memory-management unit to handle
- 512K of address space instead of CP/M's usual 64K, and includes other on-
- chip functions such as DMA and serial communication.
-
- The HD64180 superchip has already made some waves. _Byte_ magazine
- has featured it in Steve Ciarcia's SB180 project, a powerful single-board
- computer (_Byte_, September and October, 1985). Ciarcia will also be using
- the HD64180/SB180 combination in his TurnKey Bulletin Board System project,
- scheduled for the December _Byte_.
-
- In addition, Southern Pacific Computer Products U.S.A. is advertising
- a single board computer using the HD64180. This company is even offering a
- version (the LAT1-K) that completely replaces the main board in a Kaypro
- and comes with a hard disk interface and CP/M Plus. (See their ad in
- _Byte_, October 1985.)
-
- Another interesting hardware note is the presence of three laptop
- computers running CP/M. The Epson Geneva, NEC Starlet, and Bondwell 2 all
- run standard CP/M 2.2 and come with a good set of CP/M software (WordStar
- and friends). While most laptop makers are going after the IBM-compatible
- market (and not making much headway at $2000-3000), these three are
- offering full-featured CP/M machines for $1000. A laptop, if you've never
- used one, is the ultimate peripheral for your desktop computer.
-
- [SOFTWARE] There are also some interesting things going on in CP/M
- software. An increasing number of "pop-up" or desk accessory programs are
- available for CP/M machines. I reviewed one of these, Write Hand Man,
- several issues ago, and now there are several others being advertised also:
- Presto, for Kaypro and Osborne (Spectre Technologies); Extra Desk, for
- Kaypro (Point Data Products); Handyman, a hardware board for Kaypro (Flo
- Systems); SKEYS, for Osborne Executive (INOVA); and others.
-
- And WestWind Computer now bundles a special version of SuperCalc2 with
- their RAM disk and RAM disk/hard disk combinations. They claim that their
- SuperSize SuperCalc2, in conjunction with their hardware, can handle truly
- immense spreadsheets (up to the 2 megabyte limit of SuperCalc2) and that it
- includes several new features such as local recalculation (to keep from
- having to recalculate all of a massive spreadsheet). And they are now
- making this combination available on various computers, including Osborne,
- Kaypro, and Morrow.
-
- Other interesting new software includes ModemMail (AutoSoft), a
- programmable electronic mail and bulletin board system that includes
- automatic routing and forwarding of messages to other systems (similar to
- FIDO), and an auto-install version of ZCPR3 and the Z-System (a high
- performance operating system that replaces CP/M) that should help make the
- wonders of the Z-System available to everyone. Due out soon from the Z-
- System people (Echelon, Inc.) is Term3, a programmable communications
- package.
-
- That's not all, but it's enough for now. I plan to be taking a look
- at this and other interesting new software in coming issues, starting next
- time with SmartBrain, another CP/M idea processor. In the meantime, I'd
- say things look pretty lively.
