The CP 500 range is compatible in terms of software and hardware with the American
TRS-80 Model III, using the
BASIC Level II language. All models, as well as virtually all of Prologica's computers, have their enclosures made of polyurethane resin, designed by Luciano Deviá.[4]
Models
CP 500
Early model, released in April 1982. Sold in configuration without or with one or two full-height 5" 1/4, 178 KiB disc drives.[5][3][6] There was also a graphite variation of this model released shortly before the release of the CP 500/M80.
CP 500/M80
Released in 1985, the cabinet color was changed from beige to graphite.[7] Besides this aesthetic change, the machine could operate under SO-08, a clone of
Digital Research's
CP/M, being able to access up to 64 KiB of
RAM and use the vast software library of existing CP/M software.[8] With an
RS-232 port (via an adapter connected to the proprietary CP532C port), it was also able to access the incipient
videotext systems of the time.
CP 500/M80C
Released in 1986 in white, it was 30% more compact than its predecessor (hence the "C" in the name), thanks to the use of 5" 1/4 slim height drives, now placed in a vertical position in the cabinet.[9][10] This model no longer had the cassette recorder port, although there was the corresponding hole in the metal back panel and the appropriate spaces for the cassette circuit components on the main board. It remained in production until September 1988, even after the release of the CP 500/Turbo.
CP 500/Turbo
Last release of the range in 1987.[11] Similar to the CP 500/M80C, but in graphite color and with a faster 4 MHz
CPU clock.
