I'm getting the itch to get back to Z80 stuff.
Has anyone used the STD bus, or have any parts?
I have a few card cages and cards
but never enough I/O cards!
In the least, I was planning on using the STD bus
just for expansion cards to a single board computer.

Jeffrey,
STD BUS systems are very cool toys. The open architecture and large
number of I/O options make them very attractive for the computer /
electronics hobbyist.
I have a large stash of cards and docs. Probably 500 cards and 5 linear
feet of docs in all. I also have a few custom cards, a bus analyzer
(very cool), and some breadboard cards. Sorry but, I'm not looking to
get rid of any of my treasures. Most of the docs are for Z80 CPUs and
common I/O cards. I'll be glad to look up any information on specific
cards for you.
NOTE: Several manufacturers still make STD BUS systems. They use x86
processors and run ROM basic, or various Real Time OSs. For those who
want to build their own hardware, breadboard cards are still available
from electronics suppliers.
I prefer the Z80 CPUS.
STD BUS stuff used to be very common. I've found them in all kind of
controller applications. From billboards to automated machine tools and
industrial monitoring equipment to specialized test systems. They can
still be found on ebay but are not near as common as they were. I would
expect to pay between $10 and $20 for a common card. CPU cards might be
a little higher. Many sellers on ebay do not know what a STD BUS card is
and will list them without the STD BUS designation. It makes them harder
to find but means you can get a better deal.
See ya,

I have several plastic storage bins full of mostly brand-new STD BUS cards
with software and documentation plus two or three little boxed backplanes
with power supplies.
If there's anyone interested in making an offer on the lot, please contact
me privately and I'll see about pulling together an inventory list.

There's a spot on the Bigboard II to put an STD socket, and it'll look there
for a second bank of RAM if you use the monitor's bankswitch command.
I've always wondered about the possibility of hooking a backplane in there...

I have a 9-slot STD bus backplane built into a piece of one-off lab equipment
from some physics experiment.
I made schematics
for some of the cards:
Mostek MDX-CPU-IIA - processor, system clock, CTC timer,
and static RAM or EPROM memory
Mostek MDX-MC - static RAM or EPROM memory
Mostek MDX-BCLK - TOD clock
(and some one-off IO cards)
if of any help or interest.
I was figuring on converting it into something perhaps useful sometime,
involving re-working the prototype IO cards into more general use. The
discussions of CP/M in ROM might be interesting to consider for it.
I was reminded of the STD bus while reading the other thread about minimal CP/M
or home-brew Z80 systems, the STD bus being tailored for the Z80 (and a lot
simpler than S100).

I used STD bus at work a long time ago for motion control stuff.
Memory's a bit hazy.
