Board uses full 32 bits on STD 32 Bus
Processors are upgradable from the 33-MHz 486DX to the 66-MHz 486DX2
The ZT8911 scalable processor board is the first processor board to
operate at 32 bits across the STD 32 backplane. The board has a
replaceable CPU module that accommodates many processor options, ranging
from the 33-MHz 486DX to the 66-MHz 486DX2. The module is also designed to
support the next generation of CPUs. Memory on the board comes in the
form of 64 or 128 Kbytes of cache and up to 128 Mbytes of RAM; 2 Mbytes of
on-board flash memory provide solid-state disk and boot support for MS-DOS
and other operating systems. Other features on the board include a
watchdog timer, ac power-fail detect circuitry, additional counter/timers
for real-time programming, 24 lines of digital I/O, and on-board post-code
displays for diagnostics and program use. The ZT 8911 can serve in a
single processor system or as the primary processor in a multiprocessing
system, such as Ziatech's STD 32 Star System. This allows up to seven
DOS-based processors to operate in a single backplane, sharing peripherals
and communicating through a NetBIOS-compliant interprocessor communication
standard. (4 Mbytes RAM, 2 Mbytes flash memory, and DOS 5.0 installed, $3,
350–4 weeks ARO.) Ziatech Corp., San Luis Obispo, CA Phil Nash
