No, not in this case...I'm designing what one could call a
"hybrid" of old and new bus techniques. It carries the standard Z80
address, data, and control buses, but it has such things as out-of-
band board identification capability. The system will have a
"motherboard" on which the CPU, memory, and console ports reside, and
the bus slots will be for expansion cards.
Even
two-row 0.1" header pins would probably work well. That's
what I'll most likely use for a backplane-based Z80 system I've been
working on for a while.
Would the STD bus not fulfill that requirement/definition? (I recently received a SQUID detector data collection
instrument,
must have
been a one-off production from some physics lab. It was built
around a little
10-slot STD bus backplane and some MOSTEK STD cards (Z80 card,mem
cards,etc.)
ca 1981. Except for the RTC clock board with corroded traces from
leaking
NiCads it all looks to be re-usable.)
Wow, that sounds like a fun machine! Why don't I ever find cool
stuff like that anymore?!
