*sigh* I wish there were more collectors out in Western Canada
(I'm in Calgary at this moment...occasionally in Vancouver & Saskatoon)
Whenever I search for old stuff (even just to look at and admire
such as in a museum it's always in Ontario (or further east) which
ends up being a two-day drive for me.
There's been lots of PDP-11 stuff recently on ebay.ca, but it too
is all in Ontario
I'd LOVE to to see those Kenbak-1s...but they'r too far away.
Oh well...
Dear Bob;
I am puting together a history of low power systems and came
across the RCA 1802 as maybe the earliest single chip CMOS
processor (along with Intersil 6100). I am trying to figure out when
the RCA ICAN-7029 appnote was written and wonder if it is in
your Microsystems Manual or if you have other databooks.Thank
you.
Best Regards,
Brian
Fred, Thanks for the heads-up. I do in fact still have a couple of *brand
new* CFX-40s left for sale at $500 each. They are absolutely brand new,
unused, never worn, in the original box, with manual and hang-tag. I also
have *one* used CFX-40 in very good condition (it has a crack in the side
of the case which has been repaired with cyanoacrylate glue), which is
fully functional (everything works properly, including the light), has the
original band, and which also includes the original box, manual and
hang-tag for $300. For either new or used, add $10 S&H (incl. insurance).
Email me directly if interested, I can send pictures and references if
necessary, Scott.
The HP 5423A is a vintage piece of test equipment with an embedded HP-MX
processor. If you happen to have a master or copy of the "control" tape
(system tape) for the critter, I'd really appreciate borrowing one so I can
make a copy.
Thanks,
Lyle

I came across a decent stash of 9 track reel tapes during my clean out.
(4 cases, so maybe 50 or so of them)
A while ago, I sold or gave away (don't remember) a whole bunch of the
write protect rings for them. So I'm wondering, do those rings stop you
>from writing, or enable you to write when installed? I want to try
selling the 9 track tapes on ebay, but I want to make sure I specify the
correct status of the rings (that don't exist).
Also, are these safe to bulk erase with an electromagnet? So far none of
them have any data on them that I am worried about erasing, so I'm not
planning to bother... but I want to know if it is safe or not in case I
find one I need to.
And finally, are all 9 track tapes the same? These were used on our
General Automation Zebra machine. So will they work on any machine that
needs 9 track, or only on other Zebras?

Robbie,
>From your e-mail reply to Stan (included below), you apparently have some
knowledge of Casio CFX-400 watches. The display on my CFX-400 got wet and
isn't displaying all the numbers correctly. I would appreciate it if you
could e-mail me the contact info you have for Casio so I can get a new LCD
for my watch.
If you know anyone that has a CFX-400, I'd be willing to pay up to US$500
for a CFX-400 in good condition and up to US$200 for one that's not in
working condition.

Stan,
I've done some calling around and emailing. Casio has four distributors
that they send replacement parts to. None of them have the case in stock.
The last time a case was sold from Casio was on April 30, 1996. It was to
an individual, not a distributor.
The CFX-400 case with key pad has two part numbers. The first is 73081910.
It was later changed to 73081928, but it is the same part and description.
There are two parts still in production and available from Casio that you
may want to consider buying. They are the rubber backing seal and the LCD
(not the module, just the screen).
Good Luck.
I finally started refurb on a drive rack, a nice low-boy HP 29425 with wood
top. It's my first HP drive project that uses the 13037 subsystem, with a
7906 drive. This is so I can finally start going through all the 7905/7906
drives I have and figure out what works and what doesn't.
After going over the drive very carefully with a fine tooth comb, checking
all the power supply voltages, test point voltages, etc... the moment of
truth - hit the load switch, then turned it off just before the heads
loaded. Did this a few times to make sure the blowers sucked any stray
particles up and to the filter before letting the heads load. Finally I let
them load and got a nice clean (fortunately quiet) "drive ready". Which
leads me to my question...
In testing unknown drives and cartridges... one never knows if the heads
will come out the first time and shred against the platter. I've never been
standing around when a head crashes, but I envision horrible grinding noise
as metal shards shoot everywhere inside the drive. Is there anything I can
do other than visual inspection, before spinning up an unknown drive and
letting the heads load, to help alleviate the bad possibility of a crash on
a drive that probably hasn't been used in 25+ years?

Hi,
I was wondering if you still had that PS/1 computer for sale. Our PS/1 died
at work and we need to replace the monitor which has the power supply.
Please drop me a line and let me know

thanks!

Does anyone know what the length of the original TRS-80 model 1/3/4
printer cable was? I am considering making some (some for my own systems,
and a few to sell), but I don't know what the original length was. I'm
also curious about the length of the model 2/12/16 printer cable, though
I'd imagine it was the same length.
