REVISION HISTORY
ZT 8832
Revision 0
The ZT 8832 was originally released on 7/3/89 as Revision 0.
Revision 0.1
There were no functional changes at this revision.
Revision 0.2
A change was made to the ZT 8832 for Revision 0.2 that affects when
the STD bus control port and local control port are reset. The
Revision 0.1 board reset these control ports in response to an STD bus
SYSRESET* only. This implementation caused problems when the
ZT 8832 was used by itself because SYSRESET* was not driven.
The solution implemented in Revision 0.2 was to expand the control
port reset to include the ZT 8832 power monitor, pushbutton, and
Stage 2 watchdog timeout.
Revision 0.3
No functional changes.
Revision 0.4
The STD-80 fingers were replaced with STD 32 fingers.
A10kΩ pulldown resistor, R19, was added to the POLL* input on
the V40 processor. The POLL* input is now active low with the 8087
removed instead of floating.
