Artisan Systems DP-09 6809 Single Board Computer
The powerful DP-09 single board computer was developed by Artisan Systems Corp.
in Winchester MA.
- dual 2 MHz 68B09E processors (one used for disk control subsystem)
- memory management supporting a 1 MB address space (but only 256KB DRAM on-board)
- eight 28-pin sockets for EPROM or SRAM
- 6 serial ports (6551 ACIA)
- parallel ports (6522 VIA)
- SASI interface for hard disk drives
- supports 5.25" and 8" floppy disk drives
- 50-pin expansion connector
- 8 auto-vectored interrupts for high-speed I/O
- 4-layer PCB, approx. 11.9" x 9.0"
- FLEX and OS-9 (only Level 1?) available
- U$895 assembled and tested (populated with only 64KB DRAM and 4 serial ports)
It looks like the serial ports had no on-board RS-232 drivers or receivers, so probably
used separate adapter boards. Also, there is no mention of a battery-backed-up time-of-day
clock, which would be a major omission for a board with so many other features. It seemed
to be a very powerful system, although a bit expensive.
The only information on the DP-09 I have found so far is from ads in '68' Micro Journal,
and a press release for the INOS operating system for the DP-09 on pages 49-51 in the
issue. (INOS was a multi-user multi-tasking operating system similar to UNIX, and
was developed by Introl, the makers of the Introl C compiler.)
