CP/M-86 & MS-DOS Cross Development Environment | Discussion

Another great Retro Computer Club meet at @computinghistory.org.uk

In 1984 we bought an external hard drive for our research group's desktop computer (an NEC APC that ran a CPM86 operating system). It was the size of a shoe box and had a capacity of 10MB. This supplemented the 8" floppy disks the computer had built-in drives for, which could store about 1MB each.

A great article by Gary Kildall about CP/M in Byte Magazine Volume 06 Number 06. June 1981 (p. 217)

I think I used CPM86 on it although it did also have DRDOS.
Wrote some software to edit and programme data into eproms.

The DisplayWriter was advertised as a word processor not a computer while the DM23 was advertised as a computer that ran the BASIC language.

A customer who understood could buy the Displaywriter for less money. Get the CPM86 Operating System from Digital Research, have a much faster computer.
3/4?

The 8086 was about 4 times as powerful as the 8085. Plus you could get compilers for CPM86. The DM23 would leave you stuck with a BASIC interpreter.

So the DisplayWriter could be 16 to 20 times as fast.

See benchmarks in the Jan 1983 Byte magazine.

(4/4)

Once upon a time I worked for IBM.
The machine on the Right cost $1100 more than the one on the left. But the DisplayWriter had an 8086 CPU & the DM23 had an 8085. IBM only supplied word processing software for the Writer.
Digital Research sold CPM86 for it for $200.

Labor Value?
Low tech Marx!

... i monitor a fosfori verdi... i cavi coassiali per la rete... i connettori BNC... il CPM86... l'Honeywell con il caricamento a schede perforate... la stampante ad impatto fermata contro il muro con le staffe altrimenti andava a spasso da sola...
Nostalgia canaglia 🥲🥴

I use CPM86 and Fortran. I’m older than dirt
