If your apple monitor is the same as used on the B&W G3 series (CRT monitor),
there are several at my school and they are plugged into the Macs using what
looks like a VGA-Mac (DB15 multisync) adaptor, but the graphics output is
definitely standard Mac DB-15
Fishing through the mental archives I think I recall hearing the "dark
clicks" from a monitor before and it had to do with the resolution/sync being
something the monitor couldn't lock into. Try standard VGA 640x480, as Mac
resolutions classically were slightly different at higher levels (832x634 instead of
800x600 etc.)

I cut it down to one rack. Only one tape drive, but I don't think
this thing will be doing any large sorts in it's future.
The Dasher LP2 powers up, but gets angry when it fails to detect
the carriage has in fact reached the left-most position; FAULT.
Probably the optical sensor isn't, anymore. Pressing TEST makes
BEEP and carriage motion right, same angry beeping and FAULT.
Got all the manuals inventoried, they're listed on the website.

I'm going to power it up relatively soon. Piecemeal and carefully
of course, but without a lot of fanfare.
Bruce Ray will have right-of-first-refusal on anything, but I will
shortly have a bunch of things available for free or trade:
* two racks, one with sides
* big analog I/O system with docs and software
* DG expansion chassis
* 6023 tape drive with complete docs
I'm just trying to get the internal bus working at this point, using the (DEC
supplied?) cable that came with the machine (I don't have another cable with
the Honda connector to fit the KA43. I figure I'll try to install (NetBSD)
with the cover off & drives hanging all over the place, and then stub on a
standard connector to the outside if I need it. Unfortunately, VAXen don't seem to
have been very popular in Washington State, and my work (school library)
doesn't plug me in to classic/alternative computing people, so I'm not sure where to
go from here (toss it or try -?- )

Hi Jay
I found a connector with the correct sex and pin spacing
at HSC ( in Sunnyvale ). It doesn't have the correct external
latching so it needs slight modification with an exacto.
It seems to be staying on with just the friction of the
pin connections but one could always add some tape or something
to make sure it stayed on.

Some proprietary changes seemed to have a purpose: early SCSI vs DSSI,
others just seem in hindsight arbitrary and annoying: MMJ and goofy SCSI
connectors.
As others have mentioned, the 68 pin connector was pinned out funny.
However, the machine has two scsi busses, how about a 50 pin internal
cable attached to SCSI A and to your drive...does this cause errors, too?

I saw the collection a few months ago. It is mainly VAXen. At the time,
there were a few pdp11's and
an 8/e but most of that corner was too tightly packed to look at
easlily.
I don't know how much he was able to sell since then.
One thing he didn't mention was he had a pretty serious water break
which left several inches of water
on the side of the building with the shelving. All of the boxes with
paper on that side of the building
are water damaged.
As a longtime lurker and past member, I just couldn't not get this info out.
The Dallas - Fort Worth (mostly DEC) Historical preservation society is offering up
it's collection. Not sure of the terms, but they have a lot of good stuff.

So, now that I've got a pair of HP 21MX machines sitting here (thanks
Jay!), I could use something to toggle into them to test out the memory,
or do "nifty things" with the frontpanel lights.
I guess I could try spend some time learning HP assembly and coming up
with things myself, but it'd be nice to have some examples to look at
first. :)

The good news is that I recently acquired a VAX 8350 in good condition
along with a back plane full of cards. The bad news is that, despite all
the cards in there, the previous owner had removed the CPU cards (both of
'em, this being a dual processor machine!).
Does anybody have a KA825, T1001-YA cpu card that they'd be willing to
give away, sell, or trade for other VAXBI cards? One CPU's enough (I'll
settle for an 8250!).
And does anybody have a boot diskette (BOOT58) for an 8250/8350 that I
could copy?
Thanks much

It looks like the KA43 is bad-the internal SCSI cable worked when I connected
it to another SCSI card (via one of the drive connectors), it recognized and
mounted a disk under Linux. If anyone has another KA-43 or similar, I might be

Hello, cctech!
I recently recieved a call from a friend of a friend regarding a laptop
that has come into her posession after a coworker of her died. She was
doing some sort of environmental research, and all her work is stored on
this computer.
I tried taking the path of turning it on and just doing a copy that way.
No such luck - the plasma display has a garbled and not stable display -
text is garbled to the point that I can't read it, and it basically
looks like it's about to go straight to hell. It does boot from harddisk
- I feared that the plasma might be sensitive to power variations or
something like that, and thus tried getting the machine apart.
After struggling to get the harddrive in sight (the braindead (%(/%
&(/?/&%# engineers at Toshiba made the screen cable plug
non-detatchable!!) it has a strange plug and from what I can tell has
about 26 pins (I was counting on the ribbon, and I'm quite tired, so
that may be wrong) and the disk seems to be of JVC manufacture.
What does the plasma shakiness/garbledness mean?
What type is the disk? Can I get it out and use it on another machine,
or do i have to put the POS back together?
Is the floppy drive 1.44M?
Has anyone heard of an Ashton-Tate program called FrameWorks? If and
when I get the data off, I will need to convert this to a newer format -
what is it? Text processing? Database?
If I get the data off this machine, very cool things will come my way -
at least an LSI-11, and maybe a lot more!! *giggle like schoolgirl* So
any help is greatly appreciated!

Any X11 R3 fanatics on the list? :-)
I'm trying to get xearth to compile on this 'ere Tek XD88, which only
has X11 release 3 - xearth uses a few odds and ends which only showed up
in R4.
Question - is there an equivalent of XListPixmapFormats in release 3 or
is it something I'm going to have to bodge myself?
The other two functions for which I haven't found an R3 equivalent are
XSetWMNormalHints and XAllocSizeHints - either there isn't one or
they're lurking under different names...
I *think* there might be a R4 upgrade for the XD88 floating around on
the 'net, at least I've seen reference to one. How involved (or
complete) it is I don't know though.

More on the saga of getting the DS/DD drive working in this machine...
I borrowed a tape demagnetizer (Radio Shack doesn't carry them anymore) and
picked up some anhydrous isopropyl alcohol ($3.55 US for a pint).
Demagnetizing and cleaning the heads has done the trick. I now have two
genuine IBM (Qumetrak 142) disk drives running nicely. On the plus side, I
now also have a 30MHz scope. A fellow ham has given me one that he was not
using, with the understanding that if he needs it back he can have it.
The big question is what am I going to do with a full pint of alcohol? I
have some 8" drives to finish refurbing, but then I'll still have 99.5% of a
pint left.
Thanks for all the help.

Thanks for everyone's help in the past- adamg helped me get my Apollo running
and Dwight Elvey gave me more info on the Polymorphic Card (don't have a kbd
yet- nor any firmware so that project is on hold for a while). The S-100
manpage is great-the only manuals I couldn't find were the IDS modem and the
Digital Systems 8" floppy.
Now I'm trying to get my first VAX up, and it's having SCSI issues.
(VS3100/76, 32MB, no GFX option, no kbd/mouse, no drives,10bT tranceiver
With the cable plugged in (no devices), bus A fails with FFFFFFFF FFFFFFFF
FFFFFFFF FFFFFFFF FFFFFFFF FFFFFF03 FFFFFFFF FFFFFFFF.
If you take off the cable from the KA43, it passes the test. Presence or
absence of the terminator on the bus makes no difference.
If it were not for the fact that it works without the cable, I would assume
that the system board was dead, and probably toss it (it doesn't look easy to
replace the 5380s) but I don't want a VAX to die unnecessarily, and I'm not
sure where to go from here as far as troubleshooting.
When I got it, the SCSI cable was unplugged so it might have been yanked on
before someone realized there were clips, but it doesn't appear obviously
damaged.
Does anybody know how Digital marketing explained the 68-pin SCSI and MMJ as
improvements, or did they even try?

Does anyone have any info on the Cyber 808 Disk drive
Any specs or general info ? I think it was really made by Bryant
It was about 3 feet wide , 7 feet high, and 8 feet long.
It was hydraulic driven, and you used alcohol on a wand to clean the platters . It was a Control Data Cyber 808 disk drive. I worked on them in 1975 when they were still used at large computer centers.
In fact I made a table/lamp out of one of platters which I am trying to sell. One of a kind art. Thanks

Hello,
Does anyone in Europe, preferably Netherlands, want to get together 20 to 30
motherboards 486DX2-66, Intel ( or possibly AMD ) with at least 2 VLB slots for
Amplicon Benelux in the Netherlands. They preferred they all be the same mfg
and model and new or NOS to boot. I think they will have to settle for used and
mixed variety. I see plenty in Germany, but it seems almost no one in Germany
uses PayPal, and it seems like it just couldn't be cost effective to have them
shipped to the US and then back to Europe again. I think they should be
ones that
use a replaceable lithium coin cell in a holder because any NiCads from
that era
probably wouldn't hold a charge very well any more, and Dallas type devices
would
be at the end of their service life, and if soldered on, too much trouble
and significantly
expensive to change out. I'm pretty sure they would want them tested and
with some
kind of guarantee, though that may have to be accomplished by buying some
extras
beyond the quantity they are asking for. I don't know what their budget is
for this, but
I did think that they needed to make it enough to motivate anyone to get
involved with
it, else it looked like a "do it yourself" type project. If anyone in the
Netherlands or
Germany, that can accept Paypal, can do this, let me know. Respond to ...

I'm boycotting UPS. I walked out of there about foaming at the mouth.
I went there to ship a vintage cpu, and the gentleman behind the counter
took one look at my box and said "that box is in bad condition", followed by
"At UPS, we don't want to deliver any packages that don't look good", and
finally "we can't have the box falling apart and it's contents coming out".
I asked him to please take a closer look at the box I was shipping. True,
the outside had many shipping labels that had been pulled off. But I
explained to him it was a custom made US military shipping carton. The walls
are almost 1/2 thick cardboard with 6 inches of foam form fitting around the
cpu. There were no creases in the cardboard anywhere, and no sunken
surfaces. This box was far sturdier than any box in the place. He told me my
only choice was to take the package to The UPS Store and have them rebox it.
I think they are just trying to push business to their UPS Store fronts.
This box was extremely sturdy.
So... I'm boycotting UPS and just needed to vent :)

>Sorry, the mac mini doesn't serve my needs (I work with video and audio
>production, the stock mac mini isn't powerful or expandable enough).
Odd that you would say it isn't powerful enough... it is more powerful
then all but one model of the G4 that was released. It is equal to the
single processor Mirror Drive Door G4 Tower, and the Dual processor
version of that machine is the only G4 released that is more powerful.
And you can get a bumped up version that is faster then the single
processor MDD PowerMac G4 (but would still likely be beated by the dual
proc if you use an app that can use both procs)
Granted, if you are doing video work, I can see that even the fastest of
the G4's may just not be fast enough. But if that is the case, I assume
you are either after a dual processor G5 Tower, or you just aren't
serious about your video work (considering there is no match to it in the
Windows world.) :-)
Now... expandability... no doubt there, the mac mini is a Steve Jobs wet
dream in that respect.
(I'm not being a troll, really, I don't care what machine you use or your
reasons to or not to use it... I'm just poking fun at your claim that it
isn't powerful enough)

I may have a favor to ask. :) I may have found an ASR-33 Teletype in
Maryland that I can actually afford. Problem is, I'm in Seattle and it's a
"come pick it up" situation. (It's in or near Laurel, Maryland.)
If I end up buy it, is there someone in that area who'd be willing - for,
say, $100 plus the expenses of packing and shipping - to pick this up,
make it safe for shipping, pack it up and ship it off to Seattle?
(Conversely, is there someone in Seattle who wants to sell me a nice
ASR-33 for about $275? It'd certainly be easier for me to pick up. <g>)

<sigh> See my reply to Roger.
Me thinks one too many people has posted on this list taking their stance
too seriously... now everyone just assumes that any strange far fetched
claims like I made are done for religious zealot reasons and not for pure
silliness. (come on, you don't REALLY think that I believe that there is
no machine that can run windows that can do better then a Dual Proc G5?!?
That would be an absurd claim... even IF it was true right now, of which
not only do I have no idea, but I seriously doubt that it is... by the
time this thread dies, some company like AlienWare will have released
something that makes it false)
Sometimes, when something seems absurd, it is just that, absurd, and
needs to be taken a little less seriously (I mean come on... I DID put a
smiley face after it! Jeepers, do I really have to put
<sarcasm></sarcasm> around my comments too?)

-Commodore 128, good shape cosmetically, all cords, power supply etc,
original box, but doesn't work. It would freeze up on me, and I lost

-Zip100 for PC's (parallel port), new---I opened it, but I can't get it
to work on either of my machines. It may very well be fine, since I
can't get a Micro Solutions to work on my machines either.
-a box full of PC leftovers, a pair of earlier Pentium class chips, slot
covers, bay covers, centronics scsi cables, internal 50 pin scsi cables,
floppy cables, several fans, a small scsi drive, a small ide drive,
Hayes Accura 336 modem, drive rails, blah blah blah.....
-IBM AT motherboard, serial card, 8/16 bit VGA card, Adaptec 1542B scsi
card, 8-bit ISA MFM ST11R HD controller, Unisys Personal Workstation 2
Multiple Port Board with splitter cable drivers and instructions.
-USR Courier V Everything (older one), doesn't seem to work, but has
instructions, power supply, and good shape cosmetically..... maybe you
need a PS to fix one, or make it look better?

Firstly, I can tell you that you have a Revision C board. That's good,
as it supports 22-bit addressing in ODT (Rev.A does 18-bit. Both will
support 22-bit bus addressing under program control if the MMU is
fitted -- it's a 40-pin chip type 21-15542 in the socket nearest the
left of the board as you've drawn it).
Secondly, you've miscounted the jumpers; there are 11 in that block,
not 10. They're jumpers W5 (nearest the card edge fingers) to W15.
Just to the right of W7 is W4. W3 and W2 are resistors nearest the
right-hand edge of the board; W2 is nearer the fingers and is a real
resistor (usually) and W3 is usually a zero-ohm resistor. The one
you've shown "upright" near the top is W18, and the other one you've
shown, near the right-hand side is W1. The last two are W16 and W17,
just above the fingers at the left.
W1, W2, W3 are things like the clock and must not be removed.
W4 is the BEVENT line; when fitted, it disables BEVENT. It's normally
not fitted, unless you have a programmable clock board.
W5 and W6 select the power-up mode (0,1,2,3).
W7 is the HALT/TRAP option; when fitted, HALT traps to location 000010;
when not fitted, HALT enters ODT. Normally not fitted.
W8 selects bootstrap address for mode 2; when fitted, the processor
jumps to 173000 on power-up; when not fitted, it jumps to an address
selected by W9-W15.
W9-W15 select bootstrap address for power-up mode 2.
W16-17 are reserved and must be fitted.
W18 is the wake-up control and is almost always fitted unless you have
some external circuitry.
Power-up modes:
0: W5 out, W6 out: loads PC from 000024 and status from 00026
1: W5 in, W6 out: enters console ODT
2: W5 out, W6 in: starts bootstrap at 173000 or address from W9-W15
3: W5 in, W6 in: runs extended microcode (custom microcode ROM
option)
If BHALT is asserted when the processor is booted and W5/W6 are set to
mode 2, the processor enters console ODT instead of booting.
W9-W15 correspond to bits 9-15 (the upper byte) of the bootstrap
address for mode 2 if W8 is not fitted. Jumper inserted makes the
corresponding bit a '1'; removed makes a '0'. The lowest byte is
always 000.
You've got W18 fitted, W1 fitted (so the processor should run!) and we
don't know about the rest. However, I'd guess from your description
it's W6 that's fitted in that block, and no others.
Looks like your CPU is several jumpers short of a full set; it would
seem to be set to bootstrap from address 000000.
I'd suggest you use wire-wrap wire and a wrapping tool to jumper some
of the missing ones, or at least move the jumper off W6 and onto W5 (so
it boots into console ODT), and check that W16/W17 are fitted.
Factory default settings are W1, W2/W3, W6, W8-W18 fitted; W4, W5, W7
not fitted. That enables all the clocks and things, and sets the
processor to try to boot from 173000, and to enter ODT on HALT.
> Is the backplane termination required ?
Yes! But you could put a BDV11 or another terminator board in the last
slot, instead. You might get away without it if you only have a couple
of cards in the machine because there are terminators on the CPU.
I've not taken the SIP resistor packs out of any of my H9278s to
measure them, becasue they're a b****r to get at. However, I have some
spare DIL packs from other devices, and I can tell you that each signal
has 180 ohms to +5V and 390 ohms to GND, giving standard 120 ohm
termination. I expect those SIPs have 5V on one end and GND on the
other.

I have come across a stash of 12920/12921/12922 mux card sets. These are the
cards that are required to run pretty much any version of HP's Time Shared
BASIC.
I know some of you are working on getting up the dual CPU versions of
HP2000/TSB, but a lot of people here have just one CPU. These people could
get HP2000/E up and running - that version works on just one cpu, and no
special microcode is needed.
I know that the 12920/21/22 mux sets are pretty difficult to find, and as I
said, they are required. If you ever want to get TSB up and running you
should get in on this deal. Most everything else needed to put together a
TSB system is still fairly available, except these mux sets which are quite
rare.
The guy who has them will want real money for them. I suspect he will want
somewhere in the ballpark of $100+ bucks per set (it's a 3 card set). I'm
going to buy a set to use for a 2nd TSB machine, plus another set for a
spare. These cards probably wont be easily found again as they've all but
disappeared (to my knowledge). I don't believe his mux sets includes the
distribution panels, but the pinouts to build your own cables are well
known.
If anyone is interested, please let me know off-list immediately as I'm
getting an order ready to snag them.

Hi Guys,
Sorry for the delay - I finally got my site update posted, and the
photos of the Homebuilt TRS-80s on S-100 cards are now available.
Please visit:
http://www.parse.com/~ddunfield/museum/index.html
The Homebuilt TRS-80s are part way down in the first section
"pre-PC/non-PC systems".
Regards,
Dave

Thanks Tony! The toroids are L1 and L2, and knowing they are 30 uH helps
out a LOT! Since they are colored yellow, I am guessing they are iron
powder. The application I have in mind is harmonic surpression on 80 M
transmitters; hate to see good parts go to waste :).

Amstrads use 3" disks, except for soe that use ordinary 3.5" disks.
I'm fairly sure my ex-boss's Canon Ion camera used 2.5" disks.

Hi everybody,
Currently, I'm trying to set up a 11/23 in a BA23 box with a H9278 backplane.
Unfortunately, no information can be found on the jumper configuration for the KDF11-A (M8186).
The most important question: Does this CPU-Board provide bus termination like the KDJ11 boards ?
I plugged in some resistor packs on the dedicated sockets of the H9278 to provide termination, but nothing can be seen on the terminal (9600, 8N1).
I'm aware of the QQ/CD configuration for the first 3 slots.
The SLU-Card is a SIGMA DLV11-J clone (SDC-DLV11J). Not knowing, which of the 4 SLUs provides the console interface lead me to check out the 4 ports on my terminal, unfortunaltey without any success.
The jumper settings on the KDF11-A look like this:
top
-----------------------------
| |
| |
| | | These two upper ones are closed
| |
| __ |
| |
|
|
| __1
| | | This is a jumper block of 10 jumpers. The 9th one is open.
| | | The other ones are all closed.
| | |
| --- 10
|
| |----| |
----------- -----------
backplane
It's a bit strange, that the jumpers do not have any numbers like W1, W2 etc.
That's the reason for this drawing.
Like the KDF11-A Board, no information on the internet for the SDC-DLV11J either.
Jumper W1,W2,W3,W4 are open.
There are 6 dip switches.
On SW1, jumper 7 is closed, the rest is open, the same for SW2,SW3.
SW4: jumper 6 is closed, SW5: 4,7,8 are closed, SW6: 1,5,8 are closed, the rest is open.
Can anybody give me any hints on this configuration ?
Is the backplane termination required ?
Thanks alot in advance !
Regards,
Pierre

The manager of a local radio station here _years_ ago was going to sell me
2 Amiga 1200s he was no longer using, as he had an Amiga 4000T as his (and
his wife's) main computer. At that time, he'd mentioned that he'd never
give up the 4000T. For over 6 months after the initial meeting, I'd tried
to contact him to no avail, so eventually I gave up...
The other day, I was asked if I could repair a Win2K setup on a laptop
without requiring to reformat for him and was asked how much it would cost:
I said "One of your Amigas." He'd said "sure." I was rather expecting one
of the 1200's, but the bad news seems to be that they are probably no
longer around (but I don't know for sure) and it turns out the Amiga he
agreed to give me is the 4000T, but he needs to get some personal info off
of it first, and doesn't have (or cannot find) a keyboard or mouse for it.
I have a mouse for my Atari ST that's switchable to Amiga, but I cannot
locate it right now...
ePay doesn't seem to have too much, most of which is in the UK, so shipping
might get 1) expensive and 2) rather slow. I found some adapters that would
allow PS/2 mice to be used on them, would this be a good idea?
So, anyone have any idears where I could pick up a working, reasonably
priced keyboard/mouse set -- or is it 'nature of the beast' that the
peripherals are expensive? -- would an Amiga 2000 or 3000T keyboard work on
the 4000T?
Or: Can standard PS/2 keyboards be 'rewired' for use on them, or is it a
totally different protocol? I have *many* of these at my disposal, and
trashing a few for testing would be no big deal to me... ;-)
Thanks one and all,
Roger "Merch" Merchberger

My goal on the Tic Tac Toe machine was to build an exact replica of the Don Lancaster 1971 design. I have 2 of the MC789 inverters so I could build one unit.
I could change the design to use a TTL open collector inverter but it would be nice to have the exact circuit board. If I switched to TTL I could make the board or a kit available. (I figure a total market of under 10 units.)
The other item of a exact replica is the lamp color filters. The company AMP Hexseal still makes the filters (No.1813-27). I wonder how much they cost?
http://www.apmhexseal.com/lampfilters/filters.htm
After two years of looking a found exact replacement JFET transistors (TIS58) for my TV Typewriter restorations. The generic replacement JFET worked but it is nice to have the exact part.

I got these parts on eBay for $1.35 plus $2.70 shipping.

Hi,
I found a Fluke 9110FT "digital troubleshooter" with a 9132 "memory
interface pod" "configured for FT-68030".
Does the 9100 documentation (available on bitsavers for exemple)
applies to this model too ? Is it an enhanced version of the 9100 and
9105 ?
What would be a decent price for the lot described above ?
Thanks!

The good news is that I recently acquired a VAX 8350 in good condition
along with a back plane full of cards. The bad news is that, despite all
the cards in there, the previous owner had removed the CPU cards (both of
'em, this being a dual processor machine!).
Does anybody have a KA825, T1001-YA cpu card that they'd be willing
to give away, sell, or trade for other VAXBI cards? One CPU's enough
(I'll settle for an 8250!).
THanks,
Bob Armstrong
The Apple Disk II analog board has a couple of toroid cores on the
board; does anyone know what the permeability is, or better, what would
be the equivilent Amidon number would be?
Also, if anyone needs some of the boards, let me know. $5.00 including
USPS priority mail (they supply the box!) for up to 1 pound of boards in
the US :). These are untested pulls.

Hi
My first home brew digital project was to make
a digital dice using RTL jk-flops. I ran the thing
>from a 9 volt battery and a regulator to get to
3.6v. It drained the 9v battery in just a few
minutes of operation.
It used mercury switches to control the power and
the roll timing.
I remember going from Homestead Florida to Fort Lauderdale
to find the surplus place with the logic boards to
strip the RTL from.

Geoff Roberts asked me to post this to the list.
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5157158461
I assume the dweeb in the picture is not included. I doubt you'd want him
anyway...he looks like trouble.
So, Geoff thinks this is an 11/33. I've never even heard of an 11/33.
But there you have it. I've done my part.

Hi Joe
Unlike USPS, they do not have to take any kind
of intelligence test. I remember when I went down
to pick up my EC-1 ( Heathkit tube analog computer ).
The fellow brought the unit out and just dropped
it on the counter from about three feet. I
considered talking the the manager when I realized
that his badge said he was the manager.

I didn't know that. Does anyone have the DVD/CD? I would very much like
those transputer articles (and the software) associated with them...
Thanks,
