P > POLYMORPHIC  > POLY 88   


Polymorphic
POLY 88

The POLY 88 was a S-100 bus based computer sold in kit or assembled versions. The small case could receive the 8080 CPU board and three additional S-100 cards. Daughter boards were provided by Polymorphic to expand system capacities: video, keyboard, serial and cassette interfaces.

The system was also compatible with Altair peripherals. Originally, the computer was sold with the name "Micro-Altair", but MITS (the Altair manufacturer) required to change it quickly. So the company name became Polymorphic and its first computer, the POLY 88.

In 1976, five versions were proposed:
System 1 Kit version including 512 bytes RAM, 1 Kb. ROM monitor, 16 lines x 32 chars. video interface, keyboard input port and power supply. ($595)
System 2 System 1 plus 64 chars. per line option and cassette interface kit. ($690)
System 3 System 2 plus 8 Kb. of RAM, Basic and Assembler programs on cassette tape. ($990)
System 4 Complete kit including System 3 plus TV monitor, keyboard and cassette recorder ($1350)
System 7 System 4 assembled and ready to use. ($1350)

Thanks to Leon H. Schindel for his invaluable help
