Hi All,
Digging through some more stuff. I found a DSD 4120 (NOT 4140) qbus floppy
controller connected to two half-height 5 1/4 mitsubishi 4853-1112U
flopppy drives. One of the floppy drives had a diskette that read:
Scotch 3M
744-0 Diskette
Single Head, Single side
soft sector, single density
A quick google didn't land any hits for the DSD 4120, but a few, including
bitsavers had info on the 4140, They appear to be very similiar, but with a
few differences. The 4140 is a RX02 controller.
Is this another RX02 clone?? It's a 5 1/4 " not 8" and the floppy drive itself
is capable of over 700MB.
Could this be a RX50 clone??
Anybody senn one of these, any info??
Thanks
Cheers
Tom

Its funny that you bring that up.
I recently started with a new client, who sells Medical software (patient
charting or something to that effect, don't know exactly, just started
and I don't have anything to do with the actual software).
They are pushing wireless... I just got of a 45 minute phone call trying
to get one of the wireless tablets to reconnect to the network. WLAN was
up just fine, but it wouldn't allow any IP traffic. And of course this is
real fun to debug over the phone, trying to tell a Dr how to check and
change the settings on a tablet that has only an onscreen tappable
keyboard.
I'm dreading my next phone call to him (he had to hang up and deal with
patients), as I'm having a bad feeling the WPA key got screwed up... he
will go NUTS trying to tap in the 61 character phrase I used as the key!
(I couldn't even get it right twice, I had to tap it into wordpad and cut
and paste into the WPA key fields).

Hi, Joe
I just stumbled across the EV-831 thread while looking for a solution to
my Tape problem here at Nassau County School Board. We have a number of
old EV-831 boards wih old Sankyo 1/4 inch tape drives and are trying to
set up the boards/tapes in machines with CD burners so that we can xfer
all the old archive tapes to CD's for back-up/disaster recovery. Trouble
is we have no SW or drivers that work with the EV-831.
Could you send me Zips of the disks/programs that you mentioned in the
thread.
My email is [ mailto:john.pitts@nassau.k12.fl.us
]john.pitts(a)nassau.k12.fl.us. This would be a tremendous help. We've been
struggling with this for a couple of weeks and are at the point that we
were going to use the old (1993-94) Xenix machines that originally had the
EV-831's in them and kermit the extracted files over to a new machine with
burner HW/SW.
Anyway, TIA.

So, now that I discover I had a TU80, not TU81 controller in my 11/750,
I'm looking for a KLESI Unibus card, aka M8739. If anyone has one, I'd
be willing to offer some money or a trade of some sort.

It's possible to build one using standard parts. I'm nearly done with a schematic.
To complete it, I need to borrow a module for a very short time. Does anyone
have one they'd be willing to loan (or willing to ring out a few paths)?

I thought someone here might have an interest in these:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2254407061
I certainly have to wonder about the history behind these cases...
Based on the description, the seller has more of them too.

I have 8 UTP (RJ45) to Fiber (ST connectors) Token ring media converters
I'm looking to either trade for 8 10Base-T to 10Base-FL (ST connectors) or
sell for what I've got in them. I bought them for $10.00/ea late last year
>from someone who claimed they were Ethernet media converters. I picked
them up for a local non-profit school, but all the gear I've set up there
is Ethernet, so they certainly won't work for the intended application ;)
These came without power supplies, but need 9VDC @ 1000ma to 1500ma. I
tested one on a 1000ma supply, but I know some media converters used to
use 1500ma supplies. I also have 8 9VDC 1000ma power supplies and the
correct input connectors available for these units, but if there isn't any
interest I'm going to see if I can get credit for them, as they cost me
almost as much as the media converters.
I put up a photo that I got from the original seller of these units here:

I've been in contact with someone who is looking to get rid of a large

approximately 1900 folder sets in 11 file cabinet drawers. If anyone is

they were just a little closer, I'd certainly take them, but shipping from
Ohio would be expensive ;)

I found about 5 Lisa's doing the clean-out of the two local warehouses here
in Houston. All had some type of problem but one and it's running SCO Xenix

read the mfg. date of 4304 ?
Hi
Beside the limeaway, also put the board in a bath of
vinegar ( white distilled ) and water ( 50-50 ) for about
20 minutes. The potassium hydroxide soaks into the fiberglass
boards and will pop out again. Vinegar is one of those
acids that forms a vapor and can get inside of things.
This is also good because it will eventually evaporate.
When mounting new NiCads, put them in a plastic bag and
run single strand insulated wires from the battery to the
board ( you noticed how it went right through multi-strand
wire ).
We have this same problem in pinball machines. Also
replace any sockets that might be suspect and any dip
switches that are near.

This is my latest project. I have an Emulex TC02 that I want to use with a
pertec formatted Qualstar tape drive, model 1260.
The TC02 is plugged into a Vax 4000/400, hobbyist openvms version 7.2. It
is curious but when I start the Vax it does not see the TC02, this is at
the console prompt stage, >>>> show dev does not list the tape controller,
but >>>> show qbus lists it as a tsv05. Is this correct?
Anyway when I boot the Vax VMS does list an MSA0: drive but it is not
online or available, just what does this mean?
I also have a Dilog DQ3153, but no cables to attach the drive.
Anyone have success with hooking a Qualstar to a Vax or PDP?

Why not just print them out in a small font and then stick them to the
cable with some kind of temporary glue and then put clear heatshrink over
the label and shrink it in place? (Avery self stick labels and Avery's
label software might be good to use for this.) FWIW a lot of the new cables
that I'm seeing simply print the label on a piece of plastic then then wrap
it on the cable and tie around the ends of it with lacing cord or plastic
tie wraps.

I have a large multi-tier printer stand on casters that I use for my HP
logic analyzer setup. 1631D analyzer, 9122 dual floppy drive, 2225 printer,
probe hangers, etc. It's nice to have on that stand because I can roll it
around the work area from system to system easily.
I would like to put a computer on that stand too, that has HP-IB interface
(all the gear above is HP-IB). The primary purpose of the computer is to
interface to the logic analyzer, but I will also use it for interfacing to
my Data I/O programmer, various DOS programs like IC stat lookup, etc.
My problem is I'm not that familiar with HP DOS machines. I have particular
requirements for this and I'm not sure what model to look for. Perhaps those
familiar with HP's DOS machine lineage can suggest a machine I should look
for. Here's the criteria:
1) It has to be an HP. My TI3100 would look out of place with all the HP
gear on the rack :)
2) It has to allow putting an 8 bit ISA HP-IB card in it (or dare I say
already support HP-IB)
3) It really needs 1mb of RAM for some of the programs I want to run on it.
4) DOS version needs to be 5.0 or better, would be nice if I could use the
free DR-DOS
5) It would have to have an external serial port
6) I would like to get it on the wireless network. I was thinking of using
the zircom parallel port adapter I have, and then getting an ethernet to
wireless bridge. Of course, I have to find DOS TCP/IP drivers for the
zircom, if such a thing exists. I'm open to options here.
7) Vertical space is a premium on the rack, so I would prefer something
without a full-size monitor, preferrably an all-in-one unit rather than
separate cpu, keyboard, monitor, etc.
8) Would need at least 40mb hard disk.
9) Need a somewhat standard size keyboard (this rules out my 200LX).
So far from my looking around, the HP 110 seems very close to what I'd want.
The small vertical height of the screen is a big plus, but, I really have to
have 80x24. Plus the 110 seems to be stuck with 256k ram and only DOS 2.11.
I would LOVE to use my HP-85 for this, but alas, it isn't going to be
running promlink anytime soon. Can anyone suggest a vintage PC machine for
this purpose?
Thanks!

Hiya all
I've a number of boards (old PC motherboards, VAXen bulkhead panels /
planars) where the NiCds have 'leaked', covering areas of PCB and
metalwork / screws with a greyish 'corrosion'. What is this, and how
does one clear the boards / metalwork to get rid of it and return to
nice & clean? On the VAX TOY batteries, the corrosion seems to have
followed one battery wire (black, -ve) to the molex connector,
corroding / coating that, and then spreading across the boards...

Stumbled across a few free printing terminals today, if anyone is in
the right place and interested. Michigan State University's Salvage
yard had a few serial interface units of some sort, assorted cables,
three DEC Letterprinters and two Decwriter III's in their free pile
as of about 1:20 this afternoon. I grabbed one of each terminal,
a couple of serial line driver units, and a nice cart. I would have
taken all of them, but the truck was full. No guarantees they're
still there of course.
De
I have an ASR33 that exhibits the following symptoms in local
mode (I have not attempted to test online):
1) Paper will not advance (roller seems to move OK when turned
by hand)
2) Bell will not ring
3) When at the start of a line (carriage to the left) it will
over print several characters before it starts moving to
the right
4) Carriage returns very slowly and sometimes does not make it
all the way back
5) Filthy inside (although not as bad as when I got it... I've
vacuumed and blown a lot of crud out of it)
6) Smells a little funky... not the clean warm oil smell that
I remember from high school days
As well as being dirty, I suspect that it was improperly
lubricated by the previous owner as it seems to be particularly
sticky inside.
I also have a nearly new KSR33 from the same source that was
improperly handled to the extent that its plastic shell was
shattered (it was in a cardboard box with some newspaper, none
of the shipping bolts in place, and apparently roughly moved
around his ham shack). I have made no attempt to power up the
KSR (in case stuff got bent) but I think that it could be used
as a source of replacements if some of the parts of the ASR are
badly worn.
I would like to recruit 3 or 4 knowledgeable and highly motivated
classiccmpers (motivated by the prospect of DINNER and BEER on me)
at VCF East to completely tear down, clean, adjust, lubricate and
reassemble the ASR. I will supply all of the tools and materials
(unless you have special purpose tools that will help). I picture
a marathon operation, with the experts doing the disassembly,
assembly and adjustment work and me with a toothbrush and a pan of
Simple Green (or alcohol or kerosene or whatever solvent the experts
suggest) busily scrubbing parts as they are handed to me. With four
guys and one scrubber, could this be accomplished in a couple of
hours?
Why don't I do this myself?
1) I don't really have the space. Having the entire interior of a
hotel room to myself will be something of a luxury to me (I have
two kids). Or maybe I can ask Sellam for some space at the
festival and we can make it a spectator sport. It could even
become sort of a challenge...
"The crew at VCF East was able to rebuild an ASR33 in two hours,
how fast can the West or Europe do it?"
2) I don't have the unbroken periods of time. I have the fear that I
would get it all apart, have one of my all too frequent family
"emergencies" and then have to pack it up, resulting in lost parts
when I finally get back to it.
3) I'm a gutless wimp. If I get it apart, I'm not sure I could get
it all back together, even with the docs. I have original prints
of some of the docs and the rest in electronic form.
Email me if interested,
Thanks,
Bill

Never. You shouldn't need to clean the heads, in normal use. If you
do, you have a damaged diskette (or possibly a damaged head, which is
scraping oxide off your floppies) which you should track down, cut up,
burn, and discard.
Of course, sometimes oxide from a damaged floppy will stick to the
head, and that will then damage any other disks you put in that drive.
(or what do you use to clean them when they don't read disks
correctly)?
Cotton bud and iso-propyl alcohol. Head-cleaning disks don't do a very
good job, especially if the head is really dirty.

Since I'm going to be exhibiting, I'm interested in having a
lot of people show up for VCF East... general (or at least
technically inclined) public as well as the "usual suspects".
I noted that last fall's VCF West didn't show up on Slashdot
until Saturday at 2 PM. A number of people complained that
they would have attended with a little more notice. It did
show up on Wired on Thursday. Should we try to talk it up?
Is there a reason not to?

Hello list,
I'm trying to figure out the boot sequence on both the RK05 and RL02 drive from a PDP. Here's how I understand it so far:
1. Get the bootstrap in core either via the FP or PTR.
2. Execute bootstrap and pull in the absolute loader from 1st. sector of
512 bytes or 256 words;
i.e. copy 1st. sector of drive to core starting from 0
3. Execute absolute loader by a JMP 0.
4. ??? What happens next ???
Because of not (yet) having a RL02 nor a RK05, I'm using simh and trying to trace what's going on when I "attach rk0 rt11.dsk" and then a "boot rk0", but it's pretty difficult going..
Thanks.

So I got the VAX 4000/300, R400X, and TU-81+ that was offered a week ago
on the list... it's in excellent shape, I think there was only one
scratch among all three pieces.
Now, I got the machines, but no cables with them. I need the cables
that go from a KLESI card to the TU-81 (DD50M->DD50F), and the DSSI
cables to go from the CPU cabinet to the R400X (female HD50 to female
HD50.. aka SCSI-2 connector). I'm considering the possibility of
making my own cable for the TU-81 (no one seems to sell cheap M->F DD50
cables), but it looks like it'll either be hard or quite expensive to
get the DSSI cables new.
So does anyone have some DSSI & LESI cables (with the proper connectors
for my use) available for trade or sale at a reasonable price?

Hi, got a nice DEC 7000 with 4 CPUs 1GB of memory. AFAIK it is
the first Alpha model made. Same chassis as the VAX 7000.
This one works beautifully and sounds really nice. I had
OSF installed on it once (have the OSF CD with it, just
no license key.) I can't keep it though, because now I have
my VAX 6660 together and my last spot is gone.
I would like to trade this one for a VAX 40000 in a pedestal.
Don't you think that is a fair trade?
Pictures:
http://www.gusw.net/~schadow/dec7000.jpghttp://www.gusw.net/~schadow/dec7000open.jpg
This box is in Indianapolis, IN. If you come here you get to see
my collection of VAX6460 with vector processors and an 11/780.
You may even get a VAX6400 for free and another smaller alpha
(DEC3000 system) as a thank you gift.
This one is heavy. However, there are at least two ways to load
it: either liftgate truck, or a u-haul low-floor truck or
trailer. The low-floor trucks are really nice: cheap to rent
and easy to load (we just lay the machine on its side.)

Hello,
I have read some of your pstings at classiccmp.org.
I got a HP 7958B drive of the trash (still working) and would like to get
it running on an IEEE488 Interface.
You wrote you got it so far to read/write sector this would help me alot.
Also an interesting command would be to park the head before switching off.
Maybe you know where to get some resources or you have something yourself.
Thanks in advance,
Michael

It was once common practice to keep /usr on a separate partition,
particularly if you had small (200MB) drives, in which case most of the
root drive would be root and swap, with /usr mounted later. If you
want to prevent a user filling his space so that there's no room left
in /tmp or /var/tmp either, it might still be a good idea but otherwise
multiple partitions usually just mean that at some future date there's
enough space on the physical drive for <what_you_want>, except it's
split betwwen several partitions and therefore unusable[1] :-)

I think I've just found the one I booted it off. It's an EFS CD I
burned a long time ago; if you're still stuck I can upload the 28MB
volume header tomorrow[2] and you can burn that onto a CD-R. You can
boot a CD that only has a vh. I discovered that the first time I
burned an EFS CD, which is normally built in two files -- the volume
header (which includes the sgilabel, partition table, and things in mr
or sa), and "the rest". Unfortunately instead of cat'ing the two files
to cdrecord, I told cdrecord to write the two files on its command
line, and ended up with two data tracks instead of one.
[1] As I discovered last time I built a complete inst-able perl
under IRIX 5.3.
[2] 28MB is a bit much for my ISDN line this evening.

dksc(0,1,1) is normally the swap partition, and that's where the
installation tools put the miniroot during installation. Assuming
you've done the right things with fx, you should have a small(ish) EFS
root partition as partition 0, 1 is swap, IIRC 7 is the usr partition,
8 is the volume header, and 10 is the whole disk. My guess is that
when you booted the CD, you used one of the few that has no Indigo
(IP12) standalone unix on it. The first release of 5.3 did have it,
the next one didn't (by mistake), and AFAIK all the subsequent ones
did.
I guess the number on your CD is 812-0336-001. The first 5.3 CD was
812-0119-006 and that does work, and so do (IIRC, though it's a long
time since I did a clean install on an Indigo) 812-0336-002 et seq.
Last Indigo install I did, I used 812-0336-004, but I might have
booted it off something older. Don't try it with an XFS-capable one,
though.

Probably the drive responds correctly to the command to set the
blocksize. The Indy and later machines, and most not-too-old Suns can
do that from the boot PROM, but an Indigo can't (nor can my
Sparcstation 1).

I recently came into possession of a relatively large pile of on-topic
stuff, and have some of my own that I want to get rid of. I haven't
completed inventorying it all yet - there are a half-dozen boxes I've
yet to look through - but it's slow enough going that I'm sending
around a list of what I have inventoried in case anyone is interested.
When I get the rest gone through I'll post another list.
This stuff is all "cover shipping from Montreal and it's yours". That
includes free if picked up - drop me a line to arrange such.
Feel free to ask questions if you want more information about anything.
Except as noted, everything is untested; some items I can test if
desired - again, drop me a line.

/ \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
The list, mostly in no particular order:
TI Programmable 57 pocket calculator, including wall-wart, carrying
case, and "Making Tracks Into Programming" manual. Battery pack
included but will not charge enough to power the calculator even for
seconds. Red filter over display has come loose but is present.
Worked as of a month or two ago, when powered with wall-wart. Some
keys occasionally act a little flaky. I bought this new on 1981-01-26
and still have the receipt.
Numerous (ca. 20-30) cables, 25-pair POTS-quality wire. One end has
Centronics-50 connector; the other is loose wire ends. Length is some
small numbers of metres - about right for cross-connect within a wiring
closet.
A rackmount panel with 64 eight-conductor RJ45-style jacks on the
front; on the back, each four jacks are wired to a Centronics-50
connector. A C-50 gender-bender is attached to each. Note these are
NOT Cat-V, probably not even Cat-III - they look intended for POTS use,
or perhaps serial lines, to my eye.
A rackmount power switch/filter of some kind. It has a mains cable
(which is cut off near the box), a space where a switch has been
removed, and five outlets (two "filtered" and three "unfiltered") of
the sort you find on some computers to feed switched power to another
box - the same connector you find on the computer end of most computer
mains cords. The metal box has a corner twisted and torn; it either
suffered a peculiar accident or was attacked by someone who wanted to
get into it but couldn't be bothered to remove the screws.
Inkjet cartridge refilling equipment (syringe, hole-maker, small bottle
of black ink).
Old Sun-2-era external disk enclosure, ca. 1'x1'x4". Two DD50F SCSI
connectors and mains power connector. Contains power supply,
Micropolis 1325 drive, adapter board between SCSI and the drive, and
internal cabling to hook it all together.
EMP "Manual Mini Modem MM-102". Not acoustic-coupler, but almost that
old; has answer/off/originate switch, power-on and carrier-detect
lights. Includes wall-wart thought, but not tested, to go with it.
Captive telco cable ending in RJ11 plug; also has RJ11 "TELE JACK"
connector and DB25F connector for host.
Ten Cabletron TPT-2 AUI-to-UTP transceivers. These predate the current
10baseT standard for link test; they do not reliably detect link when
connected to (some) modern equipment, but at least two of them work
fine when connected to one another with a crossed cable. There
presumably exists 10baseT equipment they work with; as far as I know I
have none.
Hayes Smartmodem 2400. In original package, including styrofoam
packing, box, manuals, business-reply cards, wall-wart. Box has some
cosmetic damage - scuffs, small rips - but is basically intact; the
styrofoam has basically no damage and the modem's cosmetic condition
verges on pristine.
Packard Bell PB2400PLUS modem. Includes wall-wart, manuals, 5?" floppy
still in sealed envelope, styrofoam packing, but not surrounding box.
S-100 (I think) board from Cromemco, labeled "8K BYTESAVER" with eight
24-pin DIP sockets. It includes a switch labeled "PROGRAM POWER" and a
7812, so I assume it is a PROM reader/burner.
S-100 (I think) board. It looks like a memory board; it is marked
"S100" and "10032-B" and includes a 4x16 array of 18-pin DIP sockets,
all empty. It has 32 ceramic disc capacitors, presumably for
power-supply decoupling; two are physically damaged to the point where
I would not trust them to remain unshorted without testing.
SPARCstation 2 mainboard. The CPU has been replaced with a Weitek
POWER?P. No RAM. This board does not work; my best guess is that the
fault is in the CPU.
An ISA card from "ARCHIVE CORPORATION". Back-panel interface is a
DB25F, with a 50-pin header just behind this. Marked "ASSY 80530-151"
and "REV A"; the "151" and "REV A" are stamped, the "ASSY" and "80530-"
are silkscreened.
A MITEL SMART-1, whatever that is. It's marked "PAV Chaining" and
"Positive Account Code Verification With Chaining". The interfaces
are: a peculiar 3-pin power connector; a jack which is physically
RJ45-compatible; and a DB25F. I suspect the jack is actually for POTS,
since the device is marked with Canadian telco regulatory foo. The
matching power supply is included.
Two cables from Centronics-50 to DA15, with handwritten tags saying
things like "PBX<->NAV" "PRI #1".
An octopus cable from a DE9F to three DB25Ms. The DB25Ms have only
some pins present: 1 2 3 4 6 7 8 20 on two connectors, the third the
same except lacking pin 6.
Six DE9M-to-DE9F video cables from the Sun-3 days, when they used
monochrome monitors with DE9 connectors.
Three co-ax cables with BNC connectors on the ends; one marked with
masking tape and marker G, one B, and the third (apparently identical
otherwise) unmarked.
Eight NeXT video cables - the 19-pin D-shell kind. Seven are about a
foot and a half long, the other more like nine or ten feet.
A PC case. Contains practically nothing - internal wiring for the
front-panel switches is about it. No power supply or mobo.
Two Sun-3/60 cases, with power supplies but no machines or plastic
cosmetic covers - just the metal boxes with the power supplies.

TI-99/4A ("TEXAS INSTRUMENTS HOME COMPUTER"). In what appears to be
the original packaging, with power supply and TV video modulator.
Commodore 64, in what appears to be the original box, with power
supply, TV video monulator, a couple of other cables, a spare

are consistent with that theory.)
A "B.I. printer interface", supposedly for the C64.
A VOLKS 6480 modem (1200/300 BPS, autodial/autoanswer, for the C64 and
C128, if the box is to be believed).
An obviously homebrew (and rather carelessly built) reset button
attachment, supposedly for the C64.
A "Forth 64" cartridge, from "handic software ab", presumably (and
supposedly) for the C64.
A C64 three-in-one card. This has three card-edge connectors and a
three-position switch, and a single card edge to plug into a C64.
Presumably it's so you can leave three things physically connected all
the time and switch which one is logically connected with the switch,
instead of constantly swapping modules. Bears the name "NAVARONE".
A C64 four-in-one card. This has four card-edge connectors and a
single card edge to plug into a C64. There is also an enable switch
next to each socket, a reset button, and a fuse. Bears the name
APROTEK. Comes with a slip of paper which is akin to a user's manual
and a piece of ribbon cable with a card edge on one end and a card-edge
connector on the other. The conductor count and inter-connector
spacing are different from those on the gadget itself.
Two cables, about five feet long, with a peculiar DIN-shell
four-conductor connector on one end and bare wire ends on the other.
Pin placement on the connector is identical on both cables.
Something in a box which is hand-marked "Pow. Sup. C64 Repairable".
The device is marked "INPUT 117VAC 60HZ" "OUTPUT 5VDC-1.8A 9VAC9VA".
Included is a sheet with something that could reasonably be a schematic
for such a power supply, though I haven't opened the device to check
whether it matches the schematic. It has two cords, one to a North
American mains plug, the other to a 7-pin DIN-shell connector.
A "PROTECTO BIG BLUE PRINTER INTERFACE", in a box hand-marked with the
Commodore name.
A good deal of paper, including such things as documentation in French
for NetNorth/BITNET and a number of pages torn from magazines
containing computer-related articles, and documentation for a number of
games. It wouldn't surprise me to find a floppy or two amid them; I
didn't go through them in detail.

The 2109 and 2113 are available immediately. The 2108 I will get rid of
eventually, just not sure if I'll get rid of it now or in about 6 months.
All are untested and dirty. The 2109 and 2113 will clean up nicely. The 2108
is a hard luck case and a major restoration job. The 2109 and 2113 have cpu
keys, but someone glued them in or they are stuck. The key works fine, you
just can't take the key out. The 2108 has no key. I will test and clean them
first if I get a chance. No I/O or memory cards included. Some memory and/or
I/O cards will probably be available from me at a later date.

[This E-mail scanned for viruses by Declude Virus]
Blah! OK, the Indigo doesn't like my old Apple SCSI CDROM drive, even
though the Indy and my Sun Ultra 1 do... luckily I had a spare
quad-speed drive which has a sector-size jumper on the back. (So it
wasn't a bad SCSI cable or a problem with the Indigo's external SCSI
connector as it turns out)
Anyway, I'm just trying to get IRIX 5.3 from CD onto a disk in the
Indigo (one which currently has a mangled copy of 5.3 on it). I've used
the same CD to install 5.3 on the Indy previously - just not tried it
with the Indigo...
If I go view the PROM monitor and select "Install System Software", then
use the CDROM as the source device, it copies the installation program
to disk, says complete, but then dies with:
"Unable to load dksc(0,1,1)unix.IP12: file not found"
I seem to recall the Indy doing the same thing, which I think was a disk
partition problem (as in that case I was installing onto a drive that
had previously been in a PC)
So, I restarted at this time went into the PROM monitor's command
monitor and did:
"boot -f dksc(0,6,8)sashARCS dksc(0,6,7)stand/fx.ARCS"
... which was what I used for the Indy to partition the drive. On the
Indigo it just blows up with:
72912
NESTED EXCEPTION at pc: bfc11d90, first exception at bfc11d90
Any ideas what I'm doing wrong? Given that the Indigo's an R3K and the
Indy is an R4K, do I need a different boot command to load the relevant
R3K software?
I know this Indigo works - but the release of 5.3 is a copied version
that came with the Indy... maybe it's missing something I need, or maybe
SGI did different 5.3 releases for R3K and R4K machines?

I'm aware of the following up for disposal (I think they're off to
landfill at the end of next week by the sounds of it) in Cambridge, if
anyone's interested:
17 HP Xterminals
5 HP 700RX (Xterminals)
3 Vaxstation 3100
4 Large SCSI boxes
4 Medium SCSI boxes
6 BBC Bs
16 BBC type monitors
4 NCD Xterms
1 HP Entria Xterm
8 Dot matrix printers
1 DEC 3000
1 Sparc 4
1 Extremely spiky thing
1 Olivetti drive of some description
1 huge monitor box of cables
Lots of random software
I should be meeting with the chap tomorrow as I'm picking up some other
stuff from him, so hopefully I can look over everything. I *may* grab
the software and cable boxes just so I can take a proper inventory,
although I have no desire to hang onto anything other than a SCSI cable
or two.
Note 1: this is the *UK* Cambridge (I always put that in the subject,
and people always miss it :-)
Note 2: various people know about this stuff, so it's a case of first
come, first served. I can put you in touch with the chap if there is
anything you want from the list.
ps. I too am curious to know what the spiky thing is!
cheers

No, it doesn't matter. The block size is just a matter of how the data
is transferred between host and drive, and cdrecord or whatever will
write 2048-byte physical blocks no matter what. The drive that
eventually reads the CD back will de-block them as required. It's a
bit like CP/M, if you've come across CP/M's idea of 128-byte logical
sectors mapped onto whatever physical sector size (commonly 256 or 512
bytes for 5.25" floppies) the sytem uses.
But you should be making EFS CDs for IRIX ;-)

I just acquired a number of Arcnet Boot ROMs. I have no idea if these are of any value and/or interest to anyone here, but thought I'd post this information. Please let me know if you have any interest in any or all of these. Specifics are:
"Arcnet, 120A, Netware, Boot ROM, S/N: EG 0021xx - 0029xx, V3.00", I have 9 of these chips.
"Arcnet, 190ST/SBT, Netware, Boot ROM, S/N: EL 0033xx, V3.00", I have 4 of these chips.
"Netware, Arcnet, 120A, Boot PROM, V2.1x", I have only one of these chips.
If you like additional information, like the numbers on the bottom, just let me know.
Thanks for your information and interest.

Silly question, I know...
I need to create a CD with files on for access by an SGI system. Of
course, the SGI uses a CDROM drive that uses 512 byte blocks. My desktop
PC's the only thing with a CD burner in it, which is naturally set to a
block size of 2048.
>From the point of view of creating a CD, does this matter? Or is the
block size issue only to do with transferring data from the CD unit to
the host, and iso9660 is the same on both platforms?
It's one of those stupid questions that I really don't know the answer
to - I'm used to either just dealing with CDs on a PC, or using original
vendor media on systems which use 512 blocks (such as Sun and SGI)
I've only got a couple of decent branded blank CDs left in the house, or
I'd just risk trashing one and find out for myself :-)
cheers,

I have a lot of manuals I want to scan and am trying to decide upon the
best format. I'd like some opinions on the following scans of a 128-page
Franklin AceWriter manual.
On the low end is a pdf of bitmap images. It's hideous, but only 3.5 MB.
The high end is a 40 MB pdf of jpeg images. This one's easy on the eyes,
but is an awfully large download and I'm wondering if it might not print
as nicely as the bitmap.
In the middle is a pdf of compressed jpegs at 15 MB. This looks good to
my eyes, I just wonder about using compressed jpegs for archiving...
<www.applefritter.com/temp/acewriter_lo.pdf> (3.5 MB)
<www.applefritter.com/temp/acewriter_med.pdf> (15 MB)
<www.applefritter.com/temp/acewriter_hi.pdf> (40 MB)
(Disregard the incorrect ordering of the pages.)
Thoughts? Which of the three would you most want to download?

Buy, Sell and Trade at the VCF Marketplace
As always, one of the most exciting aspects of the VCF is the
Marketplace, where you can find a large and varied assortment of some
of the most fantastical old computer thingies anywhere. Find that odd
part you've been seeking out for your collection, then touch, smell,
even taste it if you like, before haggling out a deal. There is
simply no better place to buy and sell vintage computers than at the
VCF Marketplace. Vendor booths are still available. For more
information on selling at VCF East 2.0, please visit:
http://www.vintage.org/2004/east/vendor.php
Complete information about VCF East 2.0, including the speaker
schedule and exhibit roster, as well as lodging information and
driving directions, can be found on the VCF East 2.0 web pages:

Vintage Computer Festival Europa 5.0 Wrap-Up
--------------------------------------------
VCF Europa 5.0 was a smashing success! We had over 300 attendees and
close to 40 exhibitors. Hans Franke served up another fine glass of
VCF, German style.
We'd hoped to have a photo gallery of VCF Europa ready by the time of
this publishing but the last two months have been rather hectic for
us here at VCF central. Read on below to find out why.
In the meantime, the dates for VCF Europa 6.0 has already been set:
April 30 through May 1, 2005. And of course, the location will be
Muenchen (Munich), Germany, though the venue may change from its
traditional location to a larger facility.
We've added another European event to the VCF line-up: VCF Italia 1.0
will be inaugurated this September 4-5. More information will be
posted shortly to the VCF website.
We'll post our VCF Europa 5.0 photo gallery by the end of July, so
stay tuned for that.
VCF Creates PDP-1 Replica for National Science Museum of Japan
--------------------------------------------------------------
The reason we've been so busy of late is because Sellam Ismail, the
main guy behind the VCF, has been busy finishing up a replica of a
PDP-1 that was commissioned for the National Science Museum of Japan.
The NSM needed a PDP-1 for an upcoming exhibit they are unveiling on
Saturday, July 16. They contacted the Computer History Museum, but
they had none to loan out, so they were forwarded to the VCF since we
have experience building quality replicas of vintage computers. The
NSM wanted a functional replica, and so the VCF delivered.
We fabricated a near exact replica of a PDP-1 CPU cabinet and CRT
desk console. It features a functional front panel and a working CRT
playing Spacewar!
http://www.vintage.org/gallery.php?grouptag=PDP1REPLICA
On the inside we have a PC running Linux with Bob Supnik's PDP-1 SIMH
simulator providing the machine emulation and Phil Budne's graphics
display extensions to allow for Spacewar! to play.
The front panel is implemented with a custom-designed front panel
controller (FPC) designed by Andre' LaMothe of Nurve Networks[1]. The
FPC has 128 outputs (lights) and 64 inputs (switches) and connects to
the PC's parallel port. Code was added to SIMH which sends the
internal PDP-1 CPU machine registers (address bus, program counter,
accumulator, etc.) to the FPC, which then populates the appropriate
lamps on the front panel. The switch values are read by additional
code which then populates internal data structures within SIMH to
allow for user input from the front panel switches.
The replica PDP-1 was crated and sent off to Tokyo on Friday, July 2.
It'll go on display for three months beginning on July 16 at the
National Science Museum in Tokyo. The website of the National Science
Museum of Japan is here:
http://www.kahaku.go.jp/english/
Want your own PDP-1 replica? The VCF will be making available for
sale the Front Panel Controller and PDP-1 front panels. Heck, we'll
even make you a complete replica. Please send inquiries to Sellam
Ismail <sellam(a)vintage.org>.
Latest Additions to the VCF Archives
------------------------------------
This edition of the Latest Additions has a moral at the end, so pay
attention.
A couple weeks ago I was searching around in thrift stores in my local
area for some classic Atari joysticks for a friend's project[1]. At
one store I happened upon a nondescript electronic desk calculator.
However, there was something subtle about it that caught my attention.
I gave it a closer look: it was a Unicom 141P calculator. The label
on the back indicated it was made in Japan. It was definitely a 1970s
vintage. "Unicom" sounded familiar to me. I was trying to remember
the name of the calculator company for which Intel initially designed
the 4004 microprocessor (Busicom) but was drawing a blank. At any
rate, the calculator had a $5 sticker on it, so I figured it was worth
buying so I could research it later, and worst case I would have a
nice 1970s desktop calculator to add to the collection.
Well, imagine my surprise when I opened it up and found a 4004 inside
along with all the Intel 4000 series support chips! Rick Bensene, one
of the most prolific calculator collectors out there, provided me with
this information:
"Unicom was a company that was started up as a spinoff of IC maker
American Microsystems (AMI). There's little out there about the
history of the company in its early days, but it's possible that
Unicom initially started out simply OEMing machines from Busicom,
until they had developed their own chips. Busicom for a time had an
exclusive on the 4004 as the result of their joint effort with Intel
to develop a reconfigurable general purpose calculator chipset, which
ended up morphing into a microprocessor.
"I do know that Busicom did OEM their machines to a number of
different marketers of early electronic calculators, and perhaps
Unicom was one of them. Busicom's machine with the 4004 was the 141PF
(they weren't shy about recycling model numbers, as the 141 was a
lower-cost version of Busicom's first machine, the 162, which was
indeed a discrete transistor machine). The 141PF was a printing only
machine. Looking at patent information, the architecture of the
design was such that it could be adapted (part of the whole idea that
spurred the development of the 4004 in the first place) to use a
display rather than a printer.
"So, my guess (and it's just that at this point) is that the machine
you have is an adaptation of the original 141PF design, done either by
Busicom either on their own, or under contract to Unicom, which was
sold under the Unicom brand name in North America. Later, AMI sold
off the Unicom division to Rockwell, and for a while, Rockwell sold
handheld calculators under this brand, then abandoned the Unicom brand
and sold their machines (using their own chips) under the Rockwell
brand, as well as through other OEMs."
So the moral of the story is, don't judge a gift horse by its mouth :)
Many 1970s era calculators have early microprocessors, so even if you
don't find one with a 4004, it may end up containing an interesting
microprocessor contemporaneous with the 4004, or even an interesting
discrete design. But please don't go trashing old calculators just to
rip the microprocessors out of them.

to be the best calculator information site on the web, Rick Bensene's

Hi Tony,
Some 20 years ago I have had to job with the WAND and
created lot of Barcode-Stickers for the Spareparts in
our company. Now I got again the Job to filter those
parts (Usable-Non usable), but somehow someone must have
trown away the software for the Wand.
At my search in the Nert I found your remarks regarding
some application for an HX-20 (long time ago, study's)
Question: Do you still pocess those software and are
you willing/able to share it with me?
Regards from Germany
Jens

First of all, it's DCOK, not "CDOK". Second, the problem may not be in
the CPU board, it may be the PSU. E.g., it's out of tolerance and does
not assert the DCOK signal. Follow Tony's advice: check the PSU voltages
and the state of the DCOK signal before randomly swapping parts (and
certainly before rushing out to eBay to buy a new KA655 board).

I have one, but not an extra..:). External floppies are very rare, but
you can better use CF cards to transfer files.
Here you can find everything about omnibooks:
http://24.237.160.4/files/omnibook/
And there is an omnibook mailing list archive somewhere...try
googling on it.
Long time ago there was a thread about dumping the original HP card and
copying it to cf to substitute the missing original..never tryed and
no more memories on this...

The trouble with that is most non-electronic breakers need 100%
overcurrent to trip in <15 seconds, so it would take five 1500W
hair dryers to trip a 15A circuit.
This makes testing 100A three phase breakers interesting.

My favorite: (on-topic, but not computer-related)
Car starter motor is really weak, finally just won't turn
over. Lights dim and all when I turn the key. OK, $65 new battery.
Same symptom. Sigh. Well, battery was old anyway. Must be the
starter motor. $75 new starter motor, and some time under the hood.
Same symptom.
Drat! Now who knows what's broken? Start tracing power
wiring, to see what other boxes are in between....after a few minutes
of this, the positive lead from the battery *comes off in my hand*,
leaving the clamp still attached to the battery post.
Doh.
Put cable back into its little cable-side clamp, tighten down
the nuts, problem solved.
The *real* "Doh" is how I managed to change out the battery
and still not notice the loose cable!
----
Then there was the sticktiony hard drive I was trying to get
to spin up one last time by wobbling (about the spin axis) as it
tried to start up, and grabbed by some part that was live. Got maybe
a 12V shock on my finger, fried some part of the drive and that was
the end of that data.
----
Can I count grounding one of the print-head lines on an
inkjet printer with a multi-meter probe and blowing the fuse on the
power brick, or is that just SOP? Hate it when I do that.

Over the next ten days or so, I'll be dumping several bits of old
network equipment in the skip at work, and thought I'd see if anyone
here might want any of it. Before you get too excited, some of it
"needs attention", ie is faulty :-)
Firstly, there's a pile (20 or so) of Emulex Performance 4000 32-port
terminal servers. Not sure exactly which model, but I know that all
the ones I have boot over the network (we used DECnet but BOOTP/TFTP
should work just as well if set it up properly). You can get firmware
and other stuff from Emulex's FTP site (I just checked).
Each has 32 MMJ serial ports, a 10base2 BNC, 10base5 AUI, and possibly
a parallel printer port. I can provide a bundle of short MMJ-to-RJ45
cables for each, if required. Unfortunately almost all are "dead".
The common fault is a blown power supply -- they used to die regularly
-- and probably not hard to fix if you have relevant
experience/knowledge. The power supply is a 3-rail 60W circuit board,
not unlike an industry-standard 3" x 5" unit, but slightly larger, so
you might be able to persuade a standard unit to fit (spec is 5V @ 6A,
+12V @ 1.5A, -12V @ 1.0A).
The other pile I'm chucking contains a quantity of 10baseT 3Com FMS II
hubs, some with management units, some without. Most are 24-port but
some are 12-port. There should also be some 3Com PS II 40 hubs, all of
which have on-board management, and all of which are 24-port. All are
19"-rack-mountable, and have a serial port (except the ones without
management). The FMS units can accept one transceiver module in the
back; the PS II 40s can accept two, and we have some spare modules (not
sure what, but probably a few 10base5 AUI ports, one or two 10base2
with BNC connector, and some FOTs (10baseFX Fibre Optic Transceivers
with ST connectors). The older ones aren't very exciting as hubs but
are a useful source of Astec 40W (no, not 60W) 3-rail 3"x5" PSUs.
Lastly, I have an HP LaserJet 5M printer with optional 500-sheet Tray 3
and a 10base2/10baseT/Appletalk network interface, in good condition.
This is the only item I want a monetary contribution for: make me a
(small) offer.
These are PICK UP ONLY -- I haven't time or resource to ship things --
and must go within 10 days. They're "free to a good home" but without
any manuals (unless you're extremely lucky) and with absolutely no
warranty or even guarantee of electrical safety. If you want some of
this stuff, please contact me off-list.

This last weekend just gone I helped a mate sort out the dashboard
wiring in his 'new' ?400 Fiat. This wiring was mostly a mess of short
lengths of twisted together cable and melted adhesive insulting tape
due to many home modifications in its life. I did ask him to get a
service manual that included a circuit diagram but on the day we were
still without and, after the usual disclaimers about working without
docs, I went about fixing what was there.
Not only did I fix the wiring, the dashboard lighting and the clock I
installed a CD player (into the hole where most of the wires had been
hanging from) and a cigarette lighter socket so he could use his in car
charger for his phone. All went well, the dash was re-assembled, the
CD player worked, the phone charged and all the lights lit. Then my
mate got out his cigarettes and pressed the lighter home....
Eventually we realised the noise we could just hear over the somewhat
loud Metallica Black album was the rear screen wiper swishing back and
forth across a dry screen.

Someone here - not me - closed an earthing VCB on to the live 11KV board.
That made sure the power was off as it tripped the bus section and both
the remote and local incomer breakers.

Nice descriptions. It's good to know I've been doing it right for
years even though I didn't know the terminology. The last image
on the page is also how we attach silicone water pipes to the brass
fittings in the transmitters. We can't use metal clamps as they get
too hot from the RF and melt the external pipe braid.
It's also the way potato peeler blades are, or used to be, fixed to
the handles.

Hi,
I think this is covered by the 10 year rule, since it concerns pre-windows
stuff.
I am looking for the DOS_SOCK.LIB file. Its a library for developing
programs with sockets, for DOS. I found the following ref in the Microsoft
site:
> MS-DOS TCP/IP for Lanman 2.2c and Microsoft Network Clients 3.0
> support DOS Socket application and WinSock 1.1 application. Sockets.exe
> in MS-DOS TCP/IP is a terminate-and-stay-resident (TSR) program;
> it allows MS-DOS socket applications to run if they've been written
> with the Microsoft TCP/IP Sockets Development Kit Version 1.0, using
> the DOS Socket Library (DOS_SOCK.LIB) available in the Development
> Kit.
I can't find the "Microsoft TCP/IP Sockets Development Kit Version 1.0"
on the Microsoft web site, so I am wondering whether somebody may have
a copy left over.

Hi All,
Apart from the motorola x86 qbus system, I also picked up a 11/73 in a
BA11-SA
chassis. Apart from having a noisy fan, it starts to the ODT.
On looking at the cards, I noticed it had an emulex controller. I assumed it
woulf be for a mfm disk, But on closer inspection, it appears to be a
SC0310201-BX, Which and is for SMD disks.(emulates RH11,RM02,RM03,RM05, and
RP06. The pdp didn't come with any disks, and I'll probably stick an esdi or
RD disk in it, should I not find a suitable disk :-(
Assuming I can hunt up a disk, I can't seem to locate a manual on bitsavers,
or anywhere. The only manuals I located were for unibus controllers
Anybody out there have a manual they could photocopy/sell., etc
Cheers
Tom

Robert,
I ran across a message of yours from late February of last year
regarding an A&J MicroDrive. Did you ever find any useful information
about it? I don't have one, but I've just started looking. I pulled my
TS 2068 out of the attic last weekend and have been sort of
rediscovering it.
Anyhow, it's good to see that people are still using these old things.
:) I've had my 2068 since I was about 16.

Bad solder joints in power supplies bring back memories... cooked ones...
My Superboard 2 (to be exhibited at VCF East) came without a power supply,
so this intrepid owner got to build his own. Any bad solder joints are the
responsibility of exactly one party...
I kludged a STD-Bus 32K CMOS RAM card (using 16 of 6116 2kx8 parts) onto
the Superboard, and used a free set of 4 size-F NiCad cells as a battery
backup. Size F is used to make the 6-volt lantern batteries, by the way, so
the current capacity of my backup was calculated to keep the board running
without power for roughly 7 years, disregarding internal battery leakage. 7
Amp-hour NiCads can also start a fire in milliseconds: with that in mind, I
placed a service switch in series with the battery so I could take it out of
circuit if I had to fix something. Clever, right?
One day (about 1985) the power supply became intermittent and I had to
dive in to the Superboard's case to identify the problem and correct it.
Awake and alert at the time, I pulled the AC plug, then switched off the
battery. Disassembling the machine, finding the solder joint and
reassembling took me longer than expected, so it was around midnight when I
was ready to power everything back up.
Here's where circuit details caught me: my main charge circuit for the
NiCads was limited to about 5.1 volts - perfect for a 5-volt RAM card.
However, NiCads should have a "trickle" charge of 0.1-1% of capacity to keep
them healthy: for a 7Ah battery, that's 7mA (drawn from a 12-volt supply via
a resistor). This is important, since the RAM card, idle, draws 0.1mA.
Without the battery to absorb the trickle current, the RAM voltage goes
(way) out of spec. (Fortunately, the Superboard had a completely independent
regulator...)
I plug in power, then realize with horror that the battery's out of
circuit and the trickle charge is feeding 12 volts to the RAM. Yank cord.
Check everything out to see what damage was done - couldn't find anything
seriously hurt. Whew.
About 2AM, I plug the cord in again - Moron! The battery's STILL off!
This time I found 2 RAM chips shorted (and snipped the trickle charge
resistor out of circuit). It took me another week to find the last victim,
a 74HC245 bus buffer with its ground bond wire blown internally - no
physical evidence - and CMOS protection diodes on its I/O pins kept the chip
working as long as it had enough logic-0 inputs to work the logic-0 outputs.
When the Superboard READ 0FFh from the RAM board, the '245 starved and I got
errors...
In hindsight, there were so many ways to prevent that...

Hi all,
I decided to power on my MicroVAX 3800, after it's been idling for a couple of
years (unfortunately due to lack of time on my part), only to find that it's
not booting properly. The LED display on the cover/patch panel sits saying 'F'
(apparently "Waiting for CDOK"); nothing else happens. Anyone got any ideas as
to what may be wrong, or if it's fixable?
If not, there's a KA655 on eBay for 20EUR (currently), or 39EUR BIN - is this a
reasonable price?

Ok, I'm finally catching up with VCF East planning. Sorry for all the
delays.
The dates for VCF East are July 16-17 (FRIDAY and Saturday). The location
is Burlington, Massachusetts, at Sun Microsystems' corporate campus. Sun
is sponsoring the event.
Those who have already submitted exhibit entries have just been replied
to (Tom Uban: you probably won't get my e-mail due to spam blocks but rest
assured you're in there).
Current exhibitors can be seen on the VCF East 2.0 exhibits page:
http://www.vintage.org/2004/east/exhibit.php
We've got ten exhibitors so far (2 pending approval) which is a good
start, but I'd like to see more. So if you're planning to exhibit at VCF
East, now's the time to register.
I'm also putting together the speaker roster. If you have someone you'd
like to suggest as a speaker, or you'd like to give a talk yourself,
please e-mail me.
Things will start moving fast from this point forward. The next VCF
Gazette will be coming out soon with more information.
Hope to see you all at VCF East 2.0!

Hi Marvin & Jules
Yep, that is the polymorphic CPU card. The CPU is a 8080 and
the 4 sockets above the CPU are for 2111's. The three sockets
take 2708's. It is missing things like bus buffers. Marvin
or I can get you a schematic. If you get one of the vidio cards
and a parallel keyboard, you can actually do a small amount
( with the 4 2111's as RAM ). The two socket at the upper
right go to a serial buffer card and a cassette interface card.
I do have the schematic for these as well but the cassette has
a couple of chips that may be a real bear to find.
I also have the ROM monitor code and TINY BASIC that will
run on this card.

In the not too distant future I should be starting my 11/45 restoration
project. In anticipation of that....
My 11/45 front panel has a number of switches that dont work. The normal
failure mode of the switch covers breaking is not the case here. My problem
is the actual switches on the PCA under the switch covers. They have
disintegrated the way I've seen C&K switches do before. I went looking for
C&K switches a long while back for an unrelated project and had trouble
finding them.
I could just locate a whole new front panel, but those get a huge premium on
ebay. I'd just rather find the switches and solder new ones in place. Does
anyone know exactly what switch the 45 uses, and where a source for them
might be?
Thanks in advance,
Jay West

Random S100 board in the pile. Says "(c)1976 I.P.C" on the underside,
but there's nothing else by way of identification.
No obvious function for the card, but there's a few empty sockets on the
board though:
1 x 40 pins (CPU?)
4 x 18 pins (memory?)
3 x 24 pins (ROM?)
Any ideas?

Jules
I picked up one of these from a surplus store yesterday. Unfortunately
soembody removed the system card that contains the special version of
Windows and some other software from it. Does anyone have an xtra system
card or the external floppy drive for one of these?
Joe
looks to be a single board computer that a company did for some type S100 based controller. A CPU, some ram, some rom, I/O and 16 pin dips connectors to send the I/O for testing. The 40 pin chip is probably an 8080 (could be a Z80). My best guess anyway brcause I don't recognize the IPC ID.
best regards, Steve Thatcher
I didn't pick this one up yesterday as I didn't know what chance I stood
of being able to find a home for it.
However, I'll be going back to the site next week I think to rescue some
of the software that was there, and chances are good the printer will
still be there.
If someone wants it and can pick it up from me I'll make sure I grab it.
cheers,
Jules
I'm starting to make progress in going through the carload of stuff I
rescued earlier. For starters:
One of the things I found in the heap was a SWTPC CPU board. I know
nothing about them, but it looked interesting enough to be worth saving
>from an unknown fate.
However, the board's different to the one at:
http://www.computercloset.org/SWTPC6800.htm
This one has 5 larger IC sockets along the top edge, the leftmost of
which is populated. there are two 7805 regulators toward the centre of
the board at the bottom.
Bus is 50 pins, just like the card in the above photo - SW-50 I guess.
There was no sign of a case for the board, backplane, or any other cards
though.
Anyone know what the different board variations are? This one says
"MP-A2" in the top right corner along with a copyright symbol.
Build date looks to be mid-to-late 1977.
On the back, written in pencil, is "MRC original board" (which probably
doesn't mean anything to anyone!)
cheers
Jules
I was just given an A1000 with keyboard, mouse, and the external floppy
(the external floppy seems to have "issues". This is my second A1000, but
the first one is dead and was used for my public displays to show the
signatures on the inside of the case.
I haven't had time to plug it in and see if it boots, but I do know I'll be
needing a Kickstart disk. I have the version of Workbench that came with
my A500 (1.2, I think?) -- will that boot the 1000?
Nice little bonus -- it also came with the genlock slab, so I'll eventually try to
play with that.
Also, anyone have a copy of the bouncing ball demo I can have? I've never
had that, and always wanted a copy, especially since I interviewed RJ Mical
several years back and talked to him about it (he's the one who wrote it.)
While I'm in the process of purging most of my collection (those of you who
have emailed me -- I haven't forgotten you. Life just got nutty for a while
and I got behind on a lot of projects.) I'm keeping my 128K Mac and all my
Amigas (2 - 500's, A1000, and an A2000).
Thanks.

I need a datasheet for a 5204 EPROM (I'll settle for a pinout if no one has
a complete data sheet).
This is 512 bytes x 8, it's essentially half of a 2708.
Now for a big question, does anyone know if it can be programmed in a
Cromemco Bytesaver II ??? The Bytesaver II board was for 2708's; the early
documentation for the original Bytesaver (not the "II") suggested that the
original Bytesaver could program 2704's also (same size as a 5204), but
never went into a discussion of how to do it (the sockets assume 1k 2708's),
and those references are dropped from the Bytesaver II manual.
Thanks.

The only reason I can think of for nichrome is that
there would be a uniform resistance in the wire
(likely) or (unlikely) nichrome is a poor (for a
metal) conductor of heat.
My Tek 1230 is definitely plain old IDC, and that
model is worth up to and including nothing without the
probes. Probes are $400+ (without the grabbers!). I
have 3 and have turned down an offer for $300 for one
of them.
I spoke with a surplus test equipment supplier and he
told me that these are almost always lost when they go
up for auction, especially military. Off lease, they
just bill the customer and dump them surplus anyway.
I actually looked into building a probe - no
schematics, no info from TEK, custom and proprietary
IC's, and I suspect absolute analog comparator voodoo
designed for clean and fast risetimes.
Bottom line: you need to get your dough back. Accept
no less.

Next oddball find:
A board (about the size of a full-length ISA card) labelled as:
"A2000 Prototype Card V1.1",
"Interface Megavision / Megalink",
"c+p 1988 by SANG Computersysteme GmbH"
Bus is 100 pins (50 each side of the board). There's a handful of buffer
and PAL chips right by the bus connector, but otherwise it's a blank
prototype card. There's a ten pin IDC board-mounted socket in the
bottom-right corner.
Any ideas what / where / why / when? :-)

Hi
I'm not at all sure about programming the 5204 or if it even
is pin compatible with the 2708. The 2704 is program and
pin compatible with the 2708. You just program 1/2 the
address space. The algorithm is the same for both the
2708 and the 2704, otherwise.

vaxstation newbie question:
How hard is it to find vaxstation 3100 memory?
I'm finding the 4mb on-board memory is a little, eh - small - for my
needs. Seems like there are 4 "tower headers" on the motherboard which
will allow me to add some more...
Is that memory hard to find? Anyone have any lying around?

About 10 years ago I attempted to ship some donated medical equipment
>from Kansas City to China for one of our visiting Chinese doctors.
There were brand new but expired medical supplies, needles and
catheters, no chemicals. I used a very sturdy computer monitor box and
packed the entire box full. There was no extra packing just the
packaging the supplies were enclosed in. Well taped and sent express
mail.
First attempt hit US customs in California and was returned because I
shouldn't ship "medical waste" via mail. I made the mistake of
declaring the stuff to be medical scrap, since we were going to trash
it.
I then declared the items to be sterile, stainless steel and plastic,
unused and resent them. They returned in about a week because I hadn't
declared an itemized list of all items enclosed. I then opened the box
and counted every one of the sterile needles, syringes, catheters and
made a total list which was attached to the paperwork. There were over
1,000 items in the box. I still left the value at $0.
The box came back again from California since who would pay over $100
shipping on worthless items. I was mad then. I called up UPS and sent
it airfreight express and it went through without a hitch. The doctor
on the other end ended up paying over $200 in duty since there were so
many items and they must each be worth a least $1.
I think the transport brokers have a lock on the "inside track" which
makes shipping easier.
I was also going to send a complete set of medical journals but I was
tired of the hassle.

The manual for the OP-80 paper tape reader is available for download on the
internet at no cost, and has been for some time (years), from multiple
sources. It's on Howard's site, however, which may be the quickest and
easiest way to get it. These are surprisingly valuable, on a few occasions
they have gone for over $100 on E-Bay, although $40-$70 is probably more
common (that's for the reader itself, of course, not simply the manual).
Hello list,
Anybody has the manuals (tif/pdf) or software (RX50 images) for the DEC Rainbow 100?

Well, I guess I'm committed! [[ Or... I should be committed! ;-) ]]
I just made the reservations for Boston - I'll be there from Thursday the
15th thru Monday morning, so I plan on taking a long weekend to do some
sightseeing...
... I reserved at the Mariott, and the $69/nite "pay in advance" rate is
for anytime - that's not the VCF Special Rate, so if you're like me & want
to make it a longer weekend, I'd recommend taking advantage of that rate.
The wife wants to spend a day in Salem, and I wanna tour the Sam Adams
brewery... hehehe ;-)
Just thought I'd give y'all the newz...
