There's another guy who bids on virtually everything I want...
I "know" him, in that I've personally dealt with him from
time to time... I don't think he's a subscriber here, but
at any rate, I usually let him have the items, and just
shrug it off (like a large removable disk drive subsystem
that I honestly would have had trouble with shipping).
But I always get a big, big wide grin when AEK bids against
the guy, and generally wins...
BTW, the guy in question is a decent guy, didn't want to
make it seem otherwise, it's just the his collection has
no public face of any kind, and so it's like this stuff
is just being sucked into a black hole...

It just depends in the item. There will be no bargain Altairs or
IMSAIs on E-Bay. But I'm picking up 9-track magtapes for reasonable
prices, albeit slightly more expensive than Mark Tapley has been
selling them for (I'm sampling the waters, so to speak). Ditto
the more obscure stuff...
As to the view that E-Bay *should* produce the lowest prices? No
logic involved there, Dick, that's faith on the part of some
people in the open hand of Adam Smith- a view I don't share.
Comments about the failure of lassie-faire capitalism should
be directed to me personally, please...

"Private auctions?" If you mean selling at a price of "best offer,"
that's probably perfectly reasonable for something of which you can't
decide the value.
As for posting an add for an ebay auction, I won't say they can't do it,
but it annoys me. If I wanted to go to ebay to find the stuff, I would.

Perhaps it's a "right place, right time" thing. My Aviion was free.
Needs something done to repair the clamps in the SIMM socket -- I
haven't really got the equipment to solder a SIMM socket, or I'd rip one
out of a peesee mainboard for this thing.
Of course, it's difficult to find DG/UX for one, once you _have_ this
Aviion. :)
I've seen VAXStation 4000 systems for very reasonable (sub $100) prices,
which is fine, considering how many of them are still in use.
You can likely pick up free CISC AS/400s.

Well, it's kind of conceited to think that everyone wants to be a
"computer collector" these days ;) I think the other points -- especially
the recycling bit -- are right on. The solution, of course, is to find
out where is your local recycling center, and to establish a relationship
with somebody there. Many have no problems about selling computer-related
trash, especially when they can get more for it than the could by recycling
it. If you'll pay them $20 for that VAXStation 4000, you'd probably get it.

...but this is what I was talking about.
Didn't they have "diagnostic" programs available in some cases (to
field service) that would cause some of these systems to format their
own disks, anyway? I'm certain there was something to get a Qbus VAX
to format hard disks -- I mean, aside from a controller that would do
it in firmware -- but that's probably a little different.

True but where are you going to find the really clean metal
to rub on the glass? Most surfaces of metals have oxides and other
material on them. I was making the point that under real world
conditions, one can scratch glass with metal objects. One should
not assume it is safe to rub metals on glass. If the pressure is
high enough, most hardened metals can scribe glass, even though
the glass is harder. This is more related to brittleness.

This is not true. Try running your windshield wipers

All generalisations have exeptions, however it's usually the road
grit and oxides on the end of the blades that do the scratching.
And lastly, the quartz windows of the EPROMs
are harder than glass.
As can be ceramic chip packages and the PCB itself (glass

Normally I wouldn't do post here about an auction I spotted on eBay,
however, this would make a really killer starter system for someone wanting
to try out OpenVMS. I've no idea who the seller is.
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2025206674
It's an AlphaStation 200 4/233 with 256MB RAM, a 2GB & 9GB HD, and 24-Bit
graphics card, as well as the OpenVMS 7.1-2 distro, and the December 2000
layered products and doc library CD's.
BTW, it's been my experience that one of these systems with 256MB RAM rocks
(I've got one setup almost like this one).

Well, I looked at them, and the card cages are empty :(, so I grabbed one
for an endtable and a couple boxes of 'accessories' for them, including a
keyboard, twiddle box, digitizer tablets, cables, and manuals.
Let me know if anyone wants some of these things, I'm asking $10/ea or
less if you want >1 thing (all the cables together will probably count as
'one thing'. Even if I haven't listed it, ask me and I'll see if it was
included in the three boxes of crap.
There's even some VAX software I got with them on 9-track open-reel tape..

You'll need to check to see if the address is getting

It may just be a bad LED or driver on the panel,
it may be a bad switch or some other part of the cicuit.

When the code is running, they blink faster than your eye

You can't depend on boot up data in either. Most DRAMs
will boot with alternating 00/FF data. Sometimes these
are in blocks. Most statics tend to be more ramdom but
sometimes look similar in patterns to the DRAM. If you
don't know if there is RAM at a location, use the
front panel controls to change values. If there is RAM
there, it will hold the new value you wrote.

I have a IMSAI but I suspect the sequence would be similar.
STOP-RESET-EXAMINE-RUN, w/ address switches set to the
boot address. If you do have a panel problem and can't
get the address loaded properly, you could put a simple
JMP into some RAM that you can access. Toggle in
the JMP XXXX and then set the address switches to the
JMP instruction and do the EXAMINE-RUN sequence.

I have EPROMs that are over 20 years old that are still
holding data. The boot sequence is quite small and it is
unlikely to be bad. From what you said earlier, I would
suspect that the main problems may be incorrect switch
settings or problems with the fron panel.

It may be that the bit rate isn't compatable with the

Hi,
I'm quite behind on reading classiccmp postings. Has the classiccmp list been
moved to this new cctalk list?
I was subscribed to classiccmp in digest mode, and have now been automatically
subscribed to cctalk in digest mode. So far so good, except there are about 5
cctalk digests per day. Can the list admin/maintainer set things so one
digest message is sent per day, instead of several smaller ones? That kind of
defeats the object of having a digest version.

After my most recent round of Sol emulator enhancements, I'm finally
getting down to adding emulation for the Helios disk system.
Part of that effort is going to require me to get some binary disk images
in order to make the emulator do something useful.
Luckily, I happen to have a Sol stashed away along with a Helios disk
system. It was kindly donated to me last summer, but it has been in
storage waiting for me to have the time to rehabilitate it.
I bought a used varactor and ramped up the power on the Sol itself. No
caps blew, and it is now working just fine. At least, it plays TARG
OK. I've also replaced the key pads and it is now much a happier than it
was. I haven't tried messing with the helios system yet as it is going to
require a lot more work (dusting it out, cleaning things, sanity checking
it, praying like hell it doesn't need calibration after 20 years of idleness).
The system has two "Econoram by Godbout" boards, specifically "Econoram
X". Doing some probing of memory locations, it appears that only 48KB of
the available 64 KB of SRAM is enabled (each card has 64 4Kx1 SRAM
chips). 0x0000 to 0xBFFF is enabled, and the rest is disabled. Of course,
part of it must be disabled because 0xC000-0xCFFF is taken up by the
monitor ROM, display RAM, and scratch RAM. However, the higher parts
should be OK to use.
The dip switches on the boards have suggestive labels, but are too terse
for me to be confident what is going on.
Does anybody have docs on this or similar boards, or perhaps is better at
guessing what is going on than I am? I think I understand most of it, but
I'm sure I don't understand all of it.
First board's dip switch settings:
S1:
1: WE A = on
2: WE B = on
3: WE CL = on
4: WE CH = on
5: DIS A = off
6: DIS B = off
7: DIS C = off
8: WS = off
S2:
1,2,3 = A = off, off, off
4,5,6 = B = off, off, on
7,8 = C = on, off
Second board's dip switch settings:
S1:
1: WE A = on
2: WE B = on
3: WE CL = on
4: WE CH = on
5: DIS A = on
6: DIS B = on
7: DIS C = off
8: WS = off
S2:
1,2,3 = A = on, on, on
4,5,6 = B = on, on, off
7,8 = C = off, on
So it looks like the 32 KB on each board is broken up into three
banks. I'm guessing banks A and B control 8 KB blocks, and bank C is a 16
KB block (since S2 has three switches for A and B but bank C has only two
switches). WE A/B/C is write enable for each bank, and DIS A/B/C is
read&write enable/disable for each of the three banks. Perhaps WS is to
enable a wait state.
Sounds good so far, so let's collect the bank settings:
0 0 0 A1 = 0- 7, enabled
0 0 1 B1 = 8-15, enabled
1 0 C1 = 32-47, enabled
1 1 1 A2 = 56-63, disabled
1 1 0 B2 = 48-55, disabled
0 1 C2 = 16-31, enabled
Does this sound reasonable? At least it is consistent with my interpretation.
Does anybody know for sure what WS stands for?
One disturbing thing is that the I would have expected one board to
implement 0-31KB, and the other board to be used to map 32-47KB. Instead,
one board does 0-15 and 32-47, while the other board does 16-31. Any idea
why this might be?
Finally, does anybody know if this board respects phantom disable (some
other resource can claim a block of addresses and the board will silently
just map out that RAM location)?
Thanks.

I have finally got round to setting up my AS/400 and would appreciate
some advice. It came with one terminal and lots of twinax cable. The
terminal has a piece of twinax attached with a T piece on the end of it.
There are 2 twinax ports on the back of the AS/400.
How do I wire the AS/400 to the terminal? Should I just use 1 port or
does it loop through the T piece and back to the other port? Should
there be some sort of terminator which I don't have?
TIA

At one point, years ago, I acquired a set of the tools for
doing WCS microprogramming. I may still have them somewhere
in my collection, but I have not seen them for awhile.
What I do still have is a copy of the WCS user's guide, with
explanations of the microprogramming instructions and how
to use the micro assembler/loader/debugger. I attempted to
make a copy for another member of this list, but the copier
damaged several pages (not badly, but I am gun-shy about
trying it again, at least with auto-feed).
