Hello, I've been playing with my Atari 800 a bit, and the frustrating
thing is I can't get the disk drive to work. When the drive is on and with
a disk in it (is spins itself up alright) and turn on the computer, it
doesn't try to read the disk (my last Atari, and 800XL I think.. did). In
BASIC, any disk command (XIO, open, load, save, etc) give me an error that
I looked up and means something to the effect of 'drive not present'. I've
tried several utilities (myutil) on my PC to write the disks with mydos or
ataridos, but I don't know if they're working as I can't write or read any
disks.
Any ideas, please?
Thanks,
Kevin

Yes there are, Grainger is never cheap though.
As someone that has done considerable wood work, Pop was a carpenter, I
know how to buy materials and use basic tools to make nice looking stuff.
Anywho, for 80$ I'd build a long wall of wood racks. Why? The average
racks are way overbuilt. Using 3/8" or maybe 1/2" plywood or OSB is good
and 2x4s for uprights are adaquate but 1/2 or 1/3 pine straping is good
for the rest and very cheap. If carefully done using screws appearance and
disassembly should not be a problem.

Then I would think that portability and movability would be even more
important considerations.
The "prefab" steel-and-particle-board shelf units available out there
are excellent deals. Easy to set up, easy to knock down, easy to move,
and they don't cost any more than the raw materials would cost you if you
decided to roll it entirely yourself.
And there are a lot of brands available other than Gorilla. Take a look

Here's a thought.
If you've got classic computers you'd love to run but can't think of anything
to DO with them, (and they speak unix) go to http://setiathome.ssi.berkeley.edu
and make your computer's idle cycles part of the SETI search for
extraterrestrial life. They download you a chunk of data from the Arecebo
radio telescope and your computer spends its idle time running analysis on
that chunk, then sends the results back.
They keep track of what platforms people are using too. Wouldn't it be
cool if the machine that finally found a real ET signal turned out to be
a Vax 11/780 sitting in some collector's garage? They also have it as a
screensaver for mac and windows, too. For reference, a "work unit" - about
300k of data all told - will take about 20 hours to process on my PII/300
machine assuming I let it run continuously.

A company I do some work with just showed me their old system that they want
someone to cart off. From what I saw (and I'm not familiar at all with
somewhat recent IBM's), it appears to be a system/36.
There is a floorstanding deskside size cpu enclosure, two or three smaller
enclosures (same dimensions as cpu except about 8 inches tall), and a system
console with a really huge base on it. IIRC, the system said IBM 5655 or
something close to that on the front. They swear the system is in full
working order. I have no interest in this period of IBM so....
It's in St. Louis, MO, USA if anyone is interested just let me know via
email.

Look for appletalk cards in them?
Bring small philips screwdriver.
Lift 2 top covers .... one a narrow back strip .... then the big one
with smoked glass (or plastic)
slide carriage all the way left and remove ribbon
note 2 screws left and right in lower corner of opening
back all way out and lift up front cover whis has wire attached
Look inside on right ... board should have (front to back) 1 1/2 inch
connector or card mounted on it
Thats it... card or no card .... pretty valuable
Well... Its a day later and version 2.0 is online. New pictures, new
links. Check out the eta-3400.

Hi Everyone,
I've got my TK70 up and running on my uVAX but haven't been able to find a
lot of cartridges for it. Several TK50 carts, but no TK70. Imation stopped
producing them!
So if you know anyone who is decommissioning a large VAX installation that
might have a few dozen of these let me know. I'm interested in keeping the
media alive for a while at least!

I prefer Gorilla racks. I've bought/installed some of the plastic units
out there, and find two severe problems:
1) most have shelves that are NOT simple flat surfaces. Instead,
they're often some kind of exposed honeycomb (or other grid).
This has two drawbacks: (a) if you put small parts on the shelf,
they can drop through; (b) you can't slide units that have legs or
other protuberances.
2) the "heavy duty" plastic shelfs that I've used (Rubbermaid?)
start to bow under the weight of some computers

Well this week was pretty busy at auctions and checking thrift stores around
town. Many items were picked up with the following being of some interest.
a Epson Geneva PX-8 with built in micro cassette and rechargeable batteries
at Goodwill for $3
a Wang desktop with monitor, unit is gray in color and believe a 286.
a Kaypro repair Manual covering units up to the model 16 for 25 cents at
thrift.
Commodore items like a 1902 monitor, 128 unit with 1571 drive. $5 for all
some Mac 128 and 512 units, some were tossed as I have too many of these.
many Tandy units in the 1000 series.
That's it for now.

LLRR definitely wouldn't work. But LRLR will still tend to stray from the
vertical because the sloping tops all slope the same way. That is why I
suggested LRRL. This zigzag reverses the sideways displacement that occurs in
each pair of layers, thus rising vertically and being therefore more stable than
LRLR.

Hi,
Thanks for all the info. Apparently there are no reliable way to bring their
youth back, I would like to have a reliable laptop with a battery that last
more than 30 min. I found a Zenith z-star 433 VLp (500 Mb hd, 12 M RAM and
color display and the Zenith J-Mouse!!!) that I'd like to use while away
>from home. The batery I got seem to work for a while. Also it has four
contacts does this means that it provide mutiple voltages or is there some
kind of charge sense signal? I haven't brought the battery to the bench yet
(no room on or near the bench:).
Also the pack seems to be sealed pretty good, any elegant way to open it up
and reclose it without too much damage?
Thanks
Francois
PS: I actually got 3 of these laptops and built two from the set of parts
and two of the batteries are totally shot: they get very hot when I try to
charge them and of course no juice is coming out. I can practice on one of
the dead ones.

The general disdain with which PC collecting is met with on this list is
understandable, however, I have been thinking there must be something here.
I recall the folks who have collected PETs and C64s that are pretty common
and "worthless" these days (I saw a new Vic20 in box at the Hamvention that
they couldn't _give_ away.)
So I've had some thoughts on what might be useful to "collect" when it came
to the PC industry and this is what I've come up with:
1) All motherboard types - collecting one each of the "standard"
sizes (AT, XT, Baby-AT, etc)
2) Collecting one each of all processor types.
3) Collecting one each of all media types.
4) Collecting all of the video standards.
5) "Famous brands", IBM, Compaq, etc.
6) "Famous peripherals", Bus mouse, XT keyboard, AT keyboard, etc
This is something that anyone could start today since, like the computers
of yore, this stuff is currently being tossed out.
Comments?

About a week ago I was exclaiming my good fortune in being able to have
my VAXStation 2000 recognize a plain-vanilla Maxtor XT-2190 as an RD54
and proceed to format it. My concern being that if it did not recognize
it, I did not know where to find the data required. I have since found
it on www.vaxarchive.com.
My intent in formating the 2190 was to install it in my MicroVAX 2000
and have a sort of 'matched set'. I am a bit sadder and wiser now that
I have discovered that the MicroVAX is missing a rather large daughter
board that resides beneath the motherboard in the VAXStation, and
apparently carries the HDC and SCSI controller hardware.
This seems to leave using the MicroVAX as a satellite unit to the
VAXStation as the only alternative. Tried this, and MicroVAX tried to
boot from ESA0 while cabled to the VAXStation, but no-joy. Is the
problem that of not having things set up for cluster operation? If so,
how do I do that?
Keep it rather basic, please. I am pretty ignorant about all this.

I beg to respectfully differ. I got my PDP-8E for free (PDP-8E cpu, box of
spare cards, TU-56 tape drive, Paper tape reader, and a lowboy rack). Not
only that, but the collector de-racked and loaded the system in his truck by
himself, and offered to drive half way to meet me. I would suspect that this
meets anyone's definition of free (ok, so I spent some gas money for me and
him and bought him lunch).
This system is one of the most treasured in my collection. I have spent many
months painstakingly refurbishing the machine to factory new condition. So,
I have to say that people *DO* value the things they get for free. Heck, the
fact that I got it free makes me value the thing more than if I'd paid real
cash for it, at the very least because if evokes fond memories of that day
of pleasant historical computing conversation with the donor.
And - that is not the only example. A truely kind soul on this list (to whom
I am eternally gratefull) sent me an HP2108A cpu and PDP-8E 8K core board
for simply shipping charges. There are many other examples. At the very
least, since I have received this treatment from others there are times I
have already sent out items for free, and there will likely be others in the
future. That doesn't mean at ALL that I don't value them.

I have just been told about a VaxStation 3800 that is being scrapped. It
also comes with a couple of cabinets of disks (RA82's and the like), one
5' high and one about 3.5' high. If interested then contact me. It is
located in central Cambridge, UK.

Not to let the moment rewt, I found an IBM AT volume with the diagnostic disk.
Also a pristine Apple ImageWriter ll printer to go with my llc and a vol of
Toshiba Portable T1600 which according to Rax' law means one is coming my way.
