Does anyone know where I can buy some of the old IBM Hollerith 80 column punch
cards? Any help would be appreciated.
Thanks.

My research reveals that the going rate is $250 - $300 from a reseller.

They have already diagnosed the problem to a transistor on the upper board
(you know, the ones that heat up enough to discolor the circuit board). I
guess they just don't want to mess with the problem.

Hopefully someone will know about this . . . I've got this really
"comfortable" 20" monitor (Hitachi CM2085) which developed a rapidly
fluctuating left and right margin, which apparently is related to its
pincushion controls in some way.
Not being in any sense expert in repairing monitors, I fooled around with
the various accessible controls, (after removing the plastic outer shell)
such as "side-pin" among others, and managed to get the horizontal line
length to remain relatively stabile, though the screen now has a huge
pincushion distortion, which I can make go away somewhat, but when it's
gone, the rapid left/right margin fluctuation comes back, though somewhat
differently than before.
Is anyone familiar enough with this monitor or with monitors of this type to
make any kind of suggestion which might help alleviate this problem?
thanx

I got a question the other day, and it was one about which I have no clue.
A friend glommed onto an IMSAI box with a North Star disk subsystem, the FDC
for which is a model MDS-A4. He wants to know about whether it is capable
of handling 8" drives. I didn't think to ask whether it had a 50-pin cable
header on it. That would have been too easy. My recollection is that
NorthStar systems had a hard-sectored 5-1/4" drive, usually from Micropolis,
attached, and that one was pretty dense, but wouldn't do CP/M-standard
(IBM-3740 SSSD) diskettes. Is that the case with this controller?

I wonder if they will make YOU *hurt* when they go to get rid of the
equipment they have. I have always dealt with people and companies in a very
reasonable manner not to gouge or hurt them as good sales to a company in
need has usually brought excellent returns. As for individuals, nothing can
yield more vintage systems than not gouging or taking advatnage of a person
in need.
I am still getting MANY offers to purchase transistors computers today
because I chose not to gouge these same factories/companies in the past.
I have put many systems in schools (never museums) even up to some recent
donations which included a Singer mini from the 50's with acoustic memory --
in return I have received 1130 stuff (which I scrapped for $$) and many
other mini parts.
Companies and people will only treat you as well as you have treated them...

I just got a call from a place I used to work (Lucent). They have a bad
RX01 drive and want to buy a replacement. I have more than one, and I can
get their bad one as part of the deal. The problem is what to charge? I
have absolutely no idea what a reasonable price is to deliver a working drive
and haul away the broken one.
Any suggestions?

Well... reasonable cuts both ways. Perhaps I should have said, "I want to
gouge them, but not so much they buy one from someone else... how bad can
I make it hurt?" Is that better? ;-)

In progress. I've sent several mails out to various places I do business
with. I don't have phone numbers handy.

Very much true. I did mention that installation would be available for
an hourly rate.

I have other brands of NICs but a 100% NetGear infrastructure... an EN108,
8-port 10BaseT hub with 10Base2/AUI port on the back (only one works at a
time); an FE104, 100BaseT hub (currently not in use); and an FS108, 10/100
switch. *That's* the one you want. It should be available for under $200.
It supports full duplex either by negotiation (for newer stuff) or by force
via configuration switches (for older stuff). All of this stuff is tiny
with external wall warts. I like their stuff a lot.
If you don't want a big 10/100 switch, there is also a FS102 and FS104, two
and four port switch, respectively. I recommend switches over autosensing
hubs. They tend to pack more buffer RAM and allow independent collision
domains, permitting better network utilization under higher loads.

OK, another networking question since while mostly off topic (the only part
about it that is on, is the computers on the network) this list seems to
have a high level of networking knowledge.
Anyone around here familiar with Netgear hardware? I've got one of thier
4-port 10BaseT hubs, and the main things I like about it are the size, and
the lack of noise. Since it doesn't have a fan it's quiet. On the other
hand my Linksys hub is noisier than anything but the StorageWorks on my VMS
cluster. I swear the hub is even noisier than my PDP-11/73 in a BA123!!!
My thoughts are to put the Linksys hub in the garage, and get a quiet hub
for in the house. I'm currently debating either a 8-port 10/100 Switch or
Hub, and leaning towards the switch which looks to be about $100 more.
I think I almost forgot my point :^) Do the Netgear 8-port 10/100 Switches
and Hubs have fans in them? I kind of doubt that the slimline ones have
one.

The adapters are a good solution for habitual scroungers, since they come
cheap, but dual speed hubs solve the problem handsomely. They use the
signaling voltage to distinguish between the standard and fast ethernet
connections and happily route to both connection types. Unfortunately that
may have some drawbacks, e.g. now your unified segment ( the dual speed hub
does that ) operates at either speed, but at an aggregate rate equivalent to
the slower.
I use separate segments for the fast and standard ethernets, though I have a
single segment consisting of standard ethernet on RG58 and twisted pair via
a hub which is attached through one of those little AUI<=>coax adapters.
