Does anyone here have any low-capacity compact flash cards to get rid of?
I'm talking around 256 megs or less.

Just spotted this on comp.sys.dec:

Looks like an amazing item for some lucky soul. Just wish I wasn't in
the UK, bit of a long drive to pick up.

Hello,
Some of you may recall this post I sent way back in November. I received a couple of responses to the original offer, but I failed to follow through (life intervened). I have been in communication with Guy Sotomayer, who was the original first offer. He is still willing to "rescue" these things, but already has copies of them. So, we decided to see if anyone else is interested in them. If you are interested in them, I will send them off for the cost of shipping. Otherwise I will let Guy rescue them from my evil lair. :)
In addition to the list below, I have found the field maintenance print set for the RP07 drive. This pile of paper will increase the weight by about 13lbs.
Point of origin is still Madison, WI 53714 USA
I would really like to clear this stuff out as soon as I can.
Thanks for listening,
Jon

S-100 backplane board spacing
Hi, here is a rough draft of the PCB layout for a low cost S-100 prototyping
PCB I am considering.? The primary goal is to make this PCB affordable yet
still useful to S-100 hobbyists.? It is not intended to be a full blown
S-100 system or a permanent backplane but rather a bench tool.? Keeping the
costs low means a small number of connectors and?avoiding features such as
termination, etc.???Having a small number of connectors minimizes the bus
length and reduces the need for termination.? A benefit of this backplane is
a hobbyist could use it to develop new boards and/or repair older ones
without risking damage to a costly or rare vintage S-100 chassis.
?
The builder would have to supply the necessary S-100 voltages from their own
power supply.? The power supply interface is just PCB pads that could have a
connector or just direct wired to the supply.? Possible power supply
solutions would be off the shelf SMPSUs to supply +15VDC, -15VDC, and 9VDC
to the rails or alternatively surplus laptop adapters could be modified to
supply the necessary power.? A small number of boards reduces the need for
large power supply capacity.
?
The 13x2 dual row header connectors are optional for use as a stand alone
S-100 backplane.? However, they are necessary for my own project which will
use?this PCB.? PCB construction will be the usual double thickness PCB for
rigidity and double weight traces for current capacity.
?

?
If you would be interested in a PCB, please contact me off list.? My intent
is to keep this consistent with the other N8VEM PCBs so the target price is
$20 each for the PCB only plus shipping.? There is no estimate for arrival
for the PCB as of now.? I am only trying to gauge what, if any, interest
there might be in the S-100 hobbyist community.
?
Constructive comments, suggestions, and questions appreciated.? Thanks and
have a nice day!

I was just browsing around on UP and found
http://up.update.uu.se/DSK%3AHUMOR1%3BUNIX%20TEST
I took the test and got 0x72, "operator", not bad for being born after
half the things mentioned were retired :)

Hi,
I have two spare DEC 877-F power controllers (the type used in the 11/84 and 11/94). These are configured for 240V, single phase. I'm happy to post them anywhere at cost, but would prefer them to be collected. They are free, but I'm always interested in DEC stuff - any one got any covers for a BA 23 box?
Regards
Jim.
Hi!
Don' forget about the edge punched cards of "McBee Keysort Cards" so
popular in the 1960's, at least in the USA!
I still have a box of them in our basement waiting for the dumpster. Sure
brings back memories of how things have changed so much in managing data on a
personal basis.
They really helped me with my Ph.D. thesis in organic chemistry with respect
to all the references for doing the research and also for writing the thesis.
I think I saw someplace on the internet a few months ago that someone was
interested in them. If I recall correctly, they were possibly thinking about
some sort of automated system of accessing them so that the info could be put
into a computer. The cards were from sort of past big project.
So you may want to do a Google search and see what you come up with.

Thining of edge-punched cards...
The original membership cards for the Cambridge University Computer
Preservation Society had 8-level paper-tape punchings along the bottom
edge giving (IIRC) 'CUCPS' (im ASCII),. the member's computer userid
(ditto) and the membership number (3 bytes, binary).
I don;t think anyone ever tried to machine-read them though.

Hi Andrew,
Before you commit you may want to consider bus termination
for the data/address/control lines. One area a troubles can
s100 to host bridge grounding and signals. You really want
the N8VEM and you S100 to ahve excellent grounds between them.
Also since your using Z80 S100 spec is that a8-15 are an echo
of A0-A7 during IO operations. Not all S100 Z80's did that but
many did and some fo the older IO boards expected that as it
allowed easier routing for the board. You may have to have bus
timing issues as ALL Z80 baords had to bend the Z80 timing to
S100 timing. I assume the bridge baord will do that.
Beware, no matter how well you design due the variables and
ages of some boards you will have boards that refuse to
behave. It's a side effect of early 8080 S100 and later
Z80 S100 and then finally IEEE696 and the subtle differnces
that evolved.

FW: Glen Slick,
Am looking for the IA's that went with the hp 10342b preprocessor. Noticed that you had it at one time. Any chance could zip me a copy and email it? Or do you know of a ftp site, web link, etc...

Rick Garza
I was always under the impression that when Intel moved to a CMOS
manufacturing process for the 8088/8086, they fixed a bug regarding a
repeated LODSB with a segment override -- that the REP prefix was
ignored (bug) in the old 8088s, and was honored (correctly) in the newer
chips. So a simple routine to try to identify the 8088 vs. the 80c88
would look something like:
mov cx,2 ; test if following instruction will be
; repeated twice.
db 0F3h,26h,0ACh ; rep es: lodsb
jcxz Yes ; intel non-CMOS chips do not care of rep
jmp Nope ; before segment prefix override, NEC and
; CMOS-tech ones does.
If I run this on my 5150 with (C)1978 8088, I see the bug (cx does not
update). If I run this on my 5160 with "80c88" printed on the chip, I
do not see the bug (cx goes to 0). So all is well, right?
Well, I use this routine in a detection library for a project I recently
completed(*) and someone is claiming that the code is broken. It
reports an 80c88 when the chip is *not* marked 80c88, but rather "8088
(C) 1983 Intel". So what's going on? Is the chip from 1983 actually an
80c88, since it doesn't have the bug? Or did Intel fix the bug before
moving to a CMOS manufacturing process?
