Creative Micro Systems
Creative Micro Systems (CMS) was a company based in California that sold various
6800 and 6809 based computer boards and systems for the EXORbus, especially for
industrial control. They were based in Los Alamitos California, or at other times
in Westminster CA or Garden Grove CA.
CMS was started by Peter and Elaine Prossen in November 1976, and some information
I found indicated the company probably ceased operation in early 2004. Peter Prossen
told me the very interesting story of how the company got started to commercialize a
computerized control system he had developed for irrigating his avocado orchard. This
system significantly reduced water consumption at a time when the cost of water was
increasing. He also told me that Microware used several CMS computer systems to
CMS sold an extensive range of boards for the EXORbus, including:
- 9600A: SBC with 6800 microprocessor, serial and parallel ports, etc.
- 9609: SBC
with 6809 microprocessor, serial and parallel ports, etc.
- 9610: EXORbus prototyping board
- 9619A: SBC
with 2 MHz 6809, 5 28-pin RAM/ROM sockets, 3 6821/PIA, 2 6551A/ACIA, 1 6840/PTM,
RTC, onboard lithium battery; two companies that mention this board are
Bell Enterprise and
Control System Labs

- 9636: 64KB non-volatile memory with 8 sockets for 8KB SRAM or EPROM
devices, onboard lithium battery, support for extended addressing, U$270
(without any memory chips); see p.50 in
'68' Micro Journal
- 9637: 16KB non-volatile SRAM, onboard batteries for data retention,
support for extended addressing, U$595; see 4th page in
IEEE New Products
- 9639: 6809 CPU board with memory management for OS-9 Level II

host adapter (to
intelligent disk storage module)
- 9671: floppy disk controller
- 9672: DMA
If anyone has more information on any of these boards, or knows of other boards CMS sold,
please contact me.
Peter Prossen also did other interesting things:
