This SBC was an extension/improvement of their earlier
. It too could
be used in a single user system or as a master in a multi-processor network.
The Systemaster II was the next evolutionary step in Teletek's line of S-100
master processors. The Systemaster II was an 8-bit, full function single
board computer consisting of 85 integrated circuits on a four-layer S-100
board. At the heart of Systemaster II was
the powerful Zilog Z80H microprocessor (H for high speed). High
performance, and greater memory density were achieved on a standard size
S-100 board through use of the the then latest LSI support circuitry. The
flexibility of using the board in a single-user or multi-processor was
possible because the Systemaster II contained all of the features required
for most applications.
These features include:
Two serial ports.
Two parallel ports.
A flexible disk interface.
64K or 128K bytes of dynamic RAM.
Reconfigurable EPROM pads for high density integrated circuits.
DMA capabilities, fully programmable.
Interrupt controller, 8 individual vectors.
Optional adapters for IEEE 488 or SCSI control.
With the above capabilities Systemaster II could provide high performance
computing power in: Word processing, Data base management, Dedicated
industrial control, Laboratory and instrumentation control etc. There
was an 8MHZ version of the board that ran the bus at that speed if other
boards could keep up. Otherwise it was set to 6MHZ. One problem
with this board is it required a large slice of the I/O address space (0H to
1FH). Other S-100 boards had to keep outside this range.
