One selling philosophy is that it is a lot less work to sell an item for $10.00
than 10 items for $1.00 each, or "make your money on each item" vs "make your
money on volume."
If someone is trying (or needs) to make money, it makes absolutely zero sense to
price items *hoping* for the right bidders to come along and bid the price up.
Take a look at the final bids on any item, and try to guess what the person who
won it was actually willing to pay. Unless you talk to the person, you will have
no idea how high the winning bidder was actually willing to go. My guess (now)
is that computermkt has a pretty good handle on what an item *can* bring, and
prices his stuff accordingly. There is also little doubt that unless he is
buying things for his collection (assuming he is a collector), it costs nothing
to put in a low bid on something and he will only win if he gets it at his bid
price.
I saw something simliar at an early VCF (Pleasanton?) where someone brought in
some interesting machines, and priced them (in my mind) rather high. Just goes
to show what I know since most of them sold!

I just noticed another trend with this seller...
He buys vintage computer items on ebay for a lowball price and then
marks it up sky high. Is he spotting "undervalued items" or is he
just pricing them with "wishful thinking"?

Does anyone know the jumper settings for the ClearPoint DCME Q2B memory?
I have one that needs the base address changed, and I'm not looking forward
to working out the jumpers by trial and error :-)
Bitsavers has data for the Q22B, but unfortunately an older board that's
quite a bit different.
Thanks,

Hi,
Does anyone know if its possible to have multiple CGA cards on an ISA
bus? I have a feeling the answer is no...
If the answer is no, can anyone recommend a good set of docs on the
bus interface of a CGA (memory mapped regions, relevant BIOS vectors,
ISA bus transactions, etc.)?
I have a project where I want to gang drive a group of CGA displays.
Initially my thoughts were to just have N computers with CGA cards and
gang drive the computers over a serial port.
However, lately the talk of hardware on this list has got me thinking
that it might be better to create a single FPGA implementation that
gang drove N cards directly and dropped the machines in the middle.
I'm thinking that on standard ISA bus only a single CGA card could be
present because its vectors and memory map are fixed and not
relocatable. So I'd need to gang up the cards by creating my own
motherboard with ISA card edge connectors where each card thinks it is
the only thing on the bus and then select individual cards and drive
them with the FPGA.
Things that would help me in this project are:
- detailed information about the CGA video card,
both electrically and software wise.
- detailed electrical information about ISA bus cycles
- existing FPGA designs that might have useful building blocks I could
steal: ISA bus cycles, CGA implementation, etc.

> I guess you should hold off on buying his PDP8 stuff
Between what Eric Smith, CHM and others have I don't think I need
any of his PDP-8 stuff. The Royotron stuff is much more rare since
the punch is used in DEC reader/punches but the info in them isn't
in the DEC service docs.
I normally don't say anything about getting stuff run up on me, but
paying $150+ to have the seller turn around and try selling scans for
$10 was depressing (only good thing is he claims 200dpi, which
won't be all that great).
I just found a box of about 10 DEC paper tape trays each having about 8
> diag tapes in it.
The few I glanced were PDP11, but there could be a few PDP8 tapes in there.
All are in excellent condiction. If you have any interest, please feel free
to contact me off list.
Thanks, Paul

Thanks! A very Merry Christmas, Newtonsday and Winter
Solstice/Yule/Midwinter to you and everyone else on this list!
Hopefully everyone on this list got something hackish today and no one
here got a stocking full of switches (by that I'm not referring to
those of the electical variety! ...a stocking full of those would
always be useful).

THANK YOU VERY MUCH, members of the collecting "community"
I should just run the paper into the shredder.
