These are eurocard sized boards with no gold plating.
I doubt there is any gold on any connectors either.

I don't know UK prices but they should be similar to the US. Scrap prices are
similar world over in the developed countries.
In the US, if it is bulky, without many circuit cards the value ranges from 5
cents per pound (motor breakage, must have copper content) (like power
supplies) to 16 cents per pound (Aluminum breakage - mixed Aluminum and other
metals) (like hard drives or computer gear with aluminum cabinets) it is sold
& bid price is calculated by weight.
Aluminum and heavy copper can raise values, especially if they are easy to
remove.
Heavy circuit cards (with relays or metal bracing) are 10 cents to 40 cents
per pound.
Poor circuit cards (Like recent PC stuff) 0 to 20 cents.
Medium circuit cards (DEC, DG & stuff from the 80s) $1.00 per pound
Good cards like (Intel multibus I - 70s, early 80s - lots of black chips,
gold chips, old silicon chips.) $1.50 - $2.00 per pound
Gold plated cards (like HP) $3.50 per pound & up (depends on age)
Cards have to be complete with edge connectors and all chips.
Gold chips alone are $8.00 to $20 per pound and sometimes more, especially
for old military.
Old gold pin backplanes are worth $20 to $50 and up
Good (25 pins in a 25 shell) clipped connectors $2.50 per pound.
This is what the scrap dealer is going to look as bidding figures. There are
deductions for problems related to the bulk of the lot (do you have to rent a
truck?)
Call a scrap dealer that is not going to bid on the lot and ask the prices
for Motor Breakage, Aluminum Breakage, Medium circuit cards and heavy circuit
cards. Also the price of Aluminum scrap, cleaned (this means all iron,
including screws, removed) Much of the value in electronic scrap is in the a
luminum and how easy it is to get out.
Someone else will have to convert to British Pounds.
Good luck and what is the stuff?

Astoria, OR
Ps You can contact me directly if you want help trying to figure out the
scrap value of the lot. I am not going to bid on it. Do you have pictures?

I have heard of people using an HP LX palmtop (the 100LX/200LX have a fuller
serial port implementation than does the 95LX) as a terminal for the type of
tasks you mention. The 200LX runs MS-DOS 5.0 on an i80186, so you should be
able to get a number of terminal emulation programs that will work on it.

Subject: Modern replica/implementation of a dumb terminal?
I was musing about the state of VT100s and other dumb terminals and
had a few ideas zing by...
<snip>
I have used my Palm Pilot as a portable terminal for reconfiguring
Cisco routers (VT100 app and a travel cable and the appropriate
RS-232 dongles). My boss at the time flipped when he saw me do it
(everybody else dragged a laptop into the server room). There are
just times when I'd like a laptop-sized-or-smaller ANSI terminal.
I can forego double-high/double-wide chars, inverse video and the
like for simplicity's sake (hardly ever used them in an app except
at the South Pole), but it should be complex enough to run a
screen editor (vi or emacs) and/or basic curses apps (Rogue/Larn/NetHack
and the like).
One place I thought BIOS replacement might be handy was in a sub-486
laptop.... just pull it out, plug it in and *voila*, it's a dumb
terminal weighing a few lbs. Yes, it's possible to drop an OS on
a floppy and add Kermit (I've already done that with a dual-720K-
floppy Zenith 8088 portabie). I'm thinking of a dedicated "instant-
on" experience.
I also have some "Net Stations" with a 5"x5" 486 motherboard stuffed
under a PC keyboard (with 4 30-pin SIMM sockets, IDE, serial, video,
and NE2000 network built-in). They don't run off batteries, but
neither do they have an intergral screen.
I've also tried to think of ways to adapt a Palm Pilot with a permanent
keyboard, but I'm not sure there's a way to do it with only one serial
port (terminals typically have at least two, even if one is dedicated
to servicing the keyboard and somewhat "invisible" to normal operation.
The final angle I've worked on is to recycle the main board in a
VT220 (being somewhat physically small), but I don't have schematics
and I don't know what signals go over the ribbon cable to the PSU/
Analog board under the CRT.
So has anyone else wrestled with how to cobble up a portable VT-100?
Anyone get any further?

Hi all,
I've just opened up my Jupiter Ace and I think the problem I'm having
with it is far more severe than a blown CPU. It looks like while I was
testing it this morning the PSU was accidentally powered up, the +12(unreg)
connection made contact with the barrel of the power jack (-ve) and the
PSU's -ve line made contact with one of the first five expansion bus pins on
the topside of the board.
The CPU was getting very hot - I've since swapped the original NEC D780C
(1982 datecode) with a Sharp LH0080 Z80-A-CPU IC. The replacement is also
getting hot (takes about a minute for either of them to hit 50deg C). Output
>from the 7805 is 5.04V steady according to my Fluke 25 DMM. Video is being
output and my TV can lock onto it, but the output is total garbage, no
difference if I remove the CPU and ROMs or have them installed. The garbage
is always the same, too, in case it matters. The replacement CPU is
known-good - it came out of a working Toshiba HX-10 MSX.
How should I proceed with this repair? I've got a Fluke 25 DMM and a Tek
466 storage scope at my disposal. Also, the schematics are almost
unreadable. I got them from home-micros.freeserve.co.uk. Anyone got a better
copy?
Thanks.

It would be worth looking to see if signals look consistent (ie outputs of
gates behave in the way you'd expect from what you see happening on the
inputs).
If you're thinking of replacing every chip at once, or one-by-one, I'd
advise against it. You won't be able to tell what's really wrong, and
random swapping might just destroy an otherwise perfectly good IC.
The 74LS166 is a serial-out shift register, and I expect that's what
generates the video stream. Since you say you always get a good consistent
picture, with characters (even if they're junk) or some cosistent pattern,
the shifter and video timing is working. That's probably where most of
your 393's are, too (they're dual 4-bit counters).
Am I right in thinking the character set is soft-loaded from the ROM? ie,
not in a character generator ROM? Then you wouldn't expect to get
recognisable characters unless the CPU can run, and the ROM is OK.
Try swapping the memory chips around. If that gives different (but
self-consistent) video, at least some of it is working. If it makes no
difference, either it's *all* fried or the buffers have gone west.
Other obvious things to check are the CPU clock and /M1 lines. The Z80
clock needs to be pulled high, your scope should be able to show if the
clock is a nice square wave that goes up to almost 5V (minimum acceptable
is about 4.5V, IIRC). The /M1 line goes low once for each instruction
fetch; it should be pulsing. The data and address lines should be pulsing.
If the CPU is free-running becasue it can't read instructons, it might be
executing NOPs or RSTs or just some random instruction, depending on
whether the data bus is stuck all-high, all-low, or at some random value.
One possible cause of CPU and SRAM getting hot is if the data bus which
they're trying to drive is stuck with an active signal. See if you can
isolate the bus, and if the CPU or video behaves differently.
I'm just giving general advice here, as I've not used an Ace in decades,
and have no idea what the circuit looks like :-)

Prices vary widely depending on how much gold is on the cards but prices seem to run from just about nothing to as much as $4/lb here in the US. Even at the high end, that's about $4 per average sized board which is pretty cheap for a usefull board IMO.

Hi
5.04 is an OK value. I wouldn't stick another Z80/780 in there until I
knew that there wasn't something else connecting a bad voltage to
the processor. You should first power up without the processor plugged
in and measure the voltages on all of the pins. Once you've confirmed
that there is no +12V or something where it shouldn't be, you can
then look for drive contention issues. With the processor removed,
find all of the CPU pins that control Writing and reading( I don't
have a Z80 pinout handy ). Use pullups to put these into their
off states ( no bus activity ).
Now check the voltages on the data and address lines. Most TTL
cause soft pullups to about 3.5V and any resistor pullup would
bring the lines to +5V. These pullups are usually on the order of
5K or larger so you should be able to pull the line down, noticably
with a 1K pull down. This will find most any of the issues with
some other part that is hard driving against the bus lines.
Once you are sure that there is nothing hard driving against
the CPU, you could then plug it back in and look for other
issues. Just plugging parts in at random would likely be a waste
of time and may even do additional damage.

How about ringing a couple up for "very rough quotes",
explaining that you have N wotsits, each weighing
M kg and see if you can get a ball-park range out of
them.
Alternatively, bid what it's worth to you - and if you
lose, ask afterwards what the winning bid was.
What sort of equipment is this? Old PCs or test gear?

I have a spare pair, maybe more. How many do you need?
But if you've killed it with low-voltage-that's-more-than-five volts,
chances are you've fried some TTL. The NMOS will survive moderate
overvoltage better than the TTL will, so you might have a bit of work on
your hands.
This might cost you a trip to the O2 shop ;-)

Depends on the boards and whats on them. The old 486 I think type chips are
worth something like $35/lb (just chips, not boards), so boards get
complicated with socketed vs soldered, and gold vs plain chips.
I tried a google and HP website search for documentation on the 800/G30
G-Class server and could not find any. Does anyone else know were a PDF is?
I would like to learn more the server I got yesterday and get it up and
running. Thanks in advance for any help.
I know we've been through this before but does anyone
have a handle on the going rate for scrap PCBs in the
UK?
The reason - I've been made aware of a quantity of now
obsolete microprocessor equipment but I'm bidding against
the scrap man. Who knows, he may be charging for the
removal but I'd hate to lose this to him.
Cheers,
Lee.

Hi,
well, I've seen some discussions back and forth around here about what things
cost "back in the day", with some wildly differing figures at times.
In St. Louis, we used to have a distributor named Ultra-Comp, who
was in the Earth City area in Maryland Heights (by the I-70/I-270
interchange).
So here's an Ultra-Comp price list of 1988 vintage:
http://dbz.icequake.net/share/doc/comphist/ultracomp_prices.pdf
Enjoy!
(BTW, my dad bought the "Ultra Turbo-10 640 system" from them.
Upgraded from a Leading Edge 256K 4.77mhz system, 1986 vintage.
In 1991, I tasted a 386-40 clone for the first time, and was forever
weaned from the 8086. Hehe.)

I used to have that in my head, but it's fuzzed a bit over the years.
When I was working for the LDOS folks in 1981, I wrote a program to read
TRSDOS 1.3 diskettes and copy the files to LDOS diskettes. I don't know
of a place where the TRSDOS 1.3 on-disk structures are written down,
though you could try Wade Fincher's manual scans at
http://www2.asub.arknet.edu/wade/operate.htm and David Keil's at
http://discover-net.net/~dmkeil/trspdf.htm.
The general idea is similar to other TRS-80 operating systems. The
other systems are well documented (especially LDOS; see my web site),
but Model III TRSDOS is different in several ways. Here's a summary of
what I remember.
Tracks are numbered from 0. The disks are single-sided. Sectors are
numbered from 1 to 18. There are 256 bytes/sector. Tracks are divided
into allocation units called granules; there are 3 sectors/granule (6
granules/track).
You should find the directory on track 17 (decimal). All sectors on
tracks *other* than 17 are written with a deleted data address mark
(this is opposite from other TRS-80 operating systems, by the way).
On track 17, sector 1 has a bitmap to show which granules are allocated.
There is one byte per track. There might be a second bitmap to show
which granules are locked out as defective. Towards the end of the
sector is the disk name and date and the AUTO command (executed if you
boot the disk).
Sector 2 has a hash table that was used to help search the directory
without reading all of it. You can ignore it if you're just reading the
disk.
The remaining sectors are full of 48-byte directory entries, with the
last 16 bytes of each sector unused. The fields are similar to what's
described in the LDOS documentation
(http://www.tim-mann.org/trs80/doc/prgguide.pdf), but there are some
differences in pesky details, like a possible off-by-1 error in the
count of the number of sectors in the file. The other main difference
is that the Model III TRSDOS directory entries are 16 bytes longer, so
that you can have more extent pointers in the entry.
Hope this helps.

Isn't there a set of schematics on the web? I was given a Jupiter Ace
pcb a while back and it came with a set of schematics. What I'm not certain
is whether this was a "real" Ace pcb (real in the sense of being a copy of
the original) or whether this was the result of a build-a-lookalike-from-scratch
project. Whichever the PCB is, the schematics match.

I'm not familiar with this particular machine, but I used to have a similar
286 based machine. A noname tawianese brand, model HL3200 or some such.
Designed to look like the Toshiba 3100, but with EGA and an MFM HDD.
The main problem with replacing the power supply with one from a generic PC
is that the original supply probably had a high voltage output to drive the
plasma display. In my 286 machine it was 205V. If you use a power supply
that doesn't have the 205V line you'll be able use an external monitor, but
not the plasma display. Which would kind of defeat the purpose of getting
it running these days.
Your best bet would be find a power supply from another machine. One from
a 286 based T3200 might do, as may one another machine with a plasma
display if you can work out what goes where. It probably won't fit in
space where the original power supply was. Either way I'd retrieve the
original power supply from the garbage to work out what goes where.
I had mine many years ago. I found it in a dumpster with a cracked screen
and no drives. This was when back when a 286 with EGA was something
special, at least to a 13 year old with no money. I got it running on an
external monitor and dumped the broken plasma display. It lived out the
rest its days in a plastic case that once held an apple 2 clone, a naked
5.25" FDD and a 30MB MFM HDD at it's side. I completed Leisure Suit Larry
1, Duke Nukem 1, Catacombs 3D and others on this beast before upgrading to
a Wang 386-16 (a full size case with room for 2 70MB MFM HDDs with noisy
bearings!) and a flaky VGA monitor with serious screen burn. A good used
VGA monitor cost around AU$200 at the time so I has to settle for one
removed from an old memorex terminal, but I could finally play Wolf 3D.
Bzzzt. Wrong answer.
I worked at Sun in the OS group and the first release that had my code
in it was Solaris 2.4. I also have bugfixes in 2.3.
Solaris 1.x is the BSD-based stuff; Solaris 2.x is the SVR4-based stuff.
SunOS is the OS proper and Solaris is the entire environment. SunOS
4.x went with Solaris 1.x and SunOS 5.x went with Solaris 2.x.

The way I remember this, the first release that bore the "Solaris"

the last release was 4.1.4 if I remember correctly. After Solaris 2.5,
the previous SunOS 4.x releases were renamed "Solaris 2.4". I think
that the list of releases that I played with at one point or another is

SunOS 4.1.1 Rev B

I don't think it's even exiting power save. When I turn it on the power light comes on and there's a click from inside the monitor. After a few seconds the yellow power save light comes on and then I hear another click from inside the monitor. When I turn the Indigo on, it powers up and plays it's tune so I know that it's started but nothing changes on the monitor.
I disconnected the video cable at the monitor and looked for sync on pin 3 and found that there was no sync* unless I started the Indigo with no monitor connected. (The sync was 63.something kHz). If I then connected the video cable to the monitor both the yellow power save and green power lights started blinking.
*I don't think the lack of sync on pin 3 indicates a problem. This monitor is suppossed to Sync-on-Green. In fact, the lack of sync on 3 when I boot the computer with the monitor connected may well indicate that the computer recognizes that this monitor doesn't use a separate sync signal.
The computer is definitely working. After trying these monitors I plugged the video cable into my usual monitor and everything worked exactly as it's supposed to.
I was wondering, if I use a logic pulser and pulse the green input on the monitor will it generate random garbage on the screen? Any thoughts on that?

Sorry it took so long to get back to you. I'm located 25 mi. south of
Chicago. This computer was bought around 1985 for around 38 thousand dollars
including software and support. It was used to evaluate Cummins diesel
engines by running through various sequences measuring the time and
pressures it monitored and compared these values with the database loaded.
the unit ran from two floppy's, I have to add the software was very buggy
and the support program from Cummins engine company did not help much. I
have included pictures you can access via

I think I may have already posted this request but I am still searching
for this.
I need a data sheet for the AT&T T7525 codec. The document should be
dated between 1991-1994, but at this point I'll take any data sheet for
that chip.
If anyone has this, please e-mail me directly at <sellam(a)vintage.org>.
I need it by the end of the week.

I didn't realise they were so different inside. I knew the Ace didn't use
the ULA but I thought the basic architecture was similar to the ZX80/ZX81
(apart from the screen memory, which I knew about). There was certainly a
rumour at the time that that was the case, but I dare say that was as much
due to the similar size and shape of case as anything else :-) Perhaps
"inspired by" is better than "based on".
I have the manuals for ZX80, ZX81, and the Jupiter ACE, and the service
manual for the ZX81, but the only one of those machines I possess is the
common-or-garden ZX81. Twice I've just missed getting a ZX80, and I've
seen a few, but I've only seen seen one ACE.

Hey I just got a Commodore and a 1541 floppy drive
I know
load "$",8
loads a catalog of what's on the disk and
load "name",8
will load something from the floppy
and I assume
save "name",8
will save it
But how do I format the disk and prepare it for use?
Thanks for your help...

I once got a "TU58i" Monitor-program in an EPROM that replaces the original
firmware of a TU58, and then should provide the ability to (re)format a TU58 or
DC100 cartridge in a normal TU58 drive. Anybody ever heard of this?
I still should have it somewhere around although I didn't use it myself, so I
have no practical experience of it. But if anyone is interested to experiment
with it, I would try to dig it out one of many boxes in my garage marked with:
"interesting things, sort out some day".

> The way I remember this, the first release that bore the "Solaris"

Nope. They did start with SunOS, the last of which being V4.1.4_U1. When
they moved to the Solaris name, SunOS got renamed to Solaris 1.1. The U1
release I have here is Solaris 1.1.2 for SPARC, which _is_ SunOS 4.1.4
with the U1 patch kit. I assume that Solaris 1.1.1 (which I also have,
somewhere) is either SunOS 4.1.3, 4.1.3_U1 or 4.1.4 without the U1 patch.
The first non-SunOS release I believe was V2.3. I have pretty much all
releases of Solaris here, and I seem to start with V2.3, and then up, all
the way to Solaris 8. That's when I stopped doing Sun, soo.. :)
I lost (read: already deleted) the original posting, so.. can whoever
started this thread contact me offlist; we'll get you V2.4 :)

Hello, I'm new here, and I've got a problem with an
old Laptop. I just purchased a Toshiba T5200 in a flea
market, which can be seen here...
http://web.ukonline.co.uk/zelandeth/computers/t5200-100/
...and I bought it for $1! A total bargain,
but...unsurprisingly, it's broken...kinda broken. I've
opened it up to determine the cause of what's wrong
with it, as it won't turn on. A little tinkering
later, and, boom, the power supply of the Laptop fries
itself up. Damage looks bad, and it stinks really
bad...a poisonous sort of smell, so I've thrown the
offending power supply to the garbage. Now I have a
laptop...with no power supply. But, is it possible to
buy a replacement power supply for this? Or, is it
even possible to just hook it up to a regular PC's
power supply?

Hi there,
I'm not a member of the list, I found it through a Google search, but I'm trying to find a home for a Xerox 860 IPS that I have. Its been in storage for the last few years in my garage, but as far as I know it works (although I haven't turned it on in a very long time). I have the model with the portrait style screen, and I also have a daisy wheel printer, the system disks, word processing software, and the user manuals. There's even a slew of 8" disks that would go with it as well. I'd rather give this to an enthusiast, rather than just throwing it away. Its really a cool system and I think deserves better than that. I live in Saint Paul, Minnesota, so keep that in mind. This thing is hideously expensive to ship anywhere; it'd have to be picked up.
Thanks,
Let me know if anyone would like this beastie. Also, because I'm not on the list you should respond to my home e-mail rather than to just the list; otherwise, I won't see your response.

Any recommendation on what to search for? I wouldn't mind trying to find a

I've got a IBM 760CD Thinkpad that I want to try and replace the HD with a
larger one that I have on hand. After looking over the laptop carefully,
and trying to find info on the IBM website I'm left with one important
question. How on earth do I replace a HD on this model?

This is a classic Xerox Word Processing system from the early 1980s. It
should be saved. It sounds like it is a great setup and complete with the
full page monitor and printer.
It would make a great museum exhibit. We were scrapping these in 1990. There
are few around. I may have some of the boot software disks in my storage
although this system is complete with software and extras.

I have no idea. Unless they needed something more sophisticated or
powerful to extract all the data (a collection of still images, video,
sounds, cartographic data, geophysical data, text, etc) along with the
indexing, in such a way as to preserve the data, its layout, and the
cross-referencing. Normal use wouldn't do that.

It would be helpful if you could identify the floppy interface in the
system. It's probably an IBX daughter card. They are probably 1024 byte
sectored MFM encoded, I assume for RMX ?
HD recovery, as people have said, is more difficult.

Hi,
I found an old "Texas Instruments Home Computer 99/4A" in the attic of the
house I purchased two years ago. It seems to be in pretty good condition,
although I don't know if it works as I have not plugged it in. There is
one game in the box. Not sure if all the cords are there, but I know the
power cord is in the box. (Box is not in great shape). Anyway, if you tell
me it is junk, I'll trash it. I've had it for 2 years so I can wait for
you to respond.

Does anyone have an address and some contacts at the computer museum
that NASA's Ames Research centre in California is putting together? There
was an article about it in the New Scientist Magazine.
Here's the reason: some time ago a museum allegedly building in
Colorado approached me about taking away some old machines I have... I
promised them, but nothing every came of it and the storage bills are
killing me now that I am retired.
I will give them away, but I do want to do it on a wholesale basis
rather than piece by piece. Here's what I have:
Dec PDP 11/34, two RK06 drives (was working when retired). Drives are,
of course, the big washing machine ones. 11/34 is in an "executive" rack.
Dec PDP ll/23, two RL02 drives, in usual tall rack. Broken pin in
ribbon cable to the mini-drives used for booting and diagnosis. RL02s were
working when retired.
Lots of manuals and some spare platters for the drives.
Quick and Timely (Seattle company) CP/M box, S100 bus. Working when
last used.
Matrox (Montreal company) CP/M box, with old analog-digital conversion
attachment, used for scientific experiment data gathering when retired.
No documentation, but some boot floppies for the above.
Commodore 8296. Beautiful looks. Last Commodore entry into the 8-bit
business computer field. With dual floppy drive. Some software.
A few miscellaneous Atari STs. monitors, floppy drives.
Since I am in Ottawa, California might be a long way to transport the
stuff but since some of it seems rare now and the Ames Research centre
seems intent on collecting stuff, they might be willing to pay for a truck

I would appreciate advice.
