Hi all,
Picked up a huge pile of old Torch hardware, software and manuals from someone
Well done!
Triple X 'prototype'
--------------------
Supposedly this was a prototype of a Triple X machine used in-house by Torch,
presumably for development purposes. I'm not 100% convinced yet but I haven't
yet been inside it! It's built into two seperate grey metal cases (hard &
floppy disk / CPU) - certainly not production-quality either, but the official
badging suggests it perhaps wasn't a homebrew project either, so who knows.
- Top metal case houses hard disk and floppy in metal case; rear just has
power and 50-pin SCSI connector.
OK, in the production XXX, the hard and floppy drives were connected to
an OMTI board, and thence to the SCSI bus. Your unit is consistent with this
- Bottom slice is the CPU box; there's a
standard-looking Triple X keyboard
attached (cable runs through a hole in the case). The front has power LED only
and stuck-on label reading: "XXX iss.2 in disguise" :-) The rear has the
following with 'proper' lettering:
50 pin SCSI running to disk unit
Low-volts out (via bodged connector) for disk unit
"Video" (small hole in case only)
The production machines have a 8 pin DIN for video.
"Torchnet" (small hole in case only)
"Disc interface" (blanked off)
RS423 (25-w D female)
Parallel (25-w D female)
Be careful. This sounds like the case from something else. Production
XXXs have 2 DB25 sockets, and both are RS232 ports (one actually carries
2 sets of RS232 signals, for a total of 3 serial ports). There is no
parallel port on the production machines....
RGB (round DIN, 8 pin)
Cassette (round DIN, 7 pin)
No cassette on prpduction machines!
Reset button (I assume)
Mains AC input
Power switch
Production machines don't have a conventional power switch. The PSU is
controlled by a relay. There's a touch-sensitive contact on the front of
the box that turns the PSU on when touched. The service processor then
keeps the PSU running, and starts up the 68K side. Touching the contact
again sends an interrupt to the service processor which tells the 68K to
sync the filesystem and shut down. The 68K tells the service processor
it's done this, and the latter then turns off the PSU.
All this requires that the NiCd battery in the PSU is good. If not, then
the thing can't start up. The official procedure at this point is to
replace the PSU -- there's no official way to charge a flat NiCd (!!!!).
"Torch Hard Disc"
-----------------
This thing weighs one hell of a lot! 2-tone brown metal case, with inbuilt
floppy, hard drive, and monitor. Data sticker gives the model as a C520 and the
serial as 84472645
Power supply is in a seperate unit (see below) but still feeds mains into the
machine via seperate plug by the looks of it, presumably for the display
circuitry.
Back-left corner:
Keyboard socket (15-w D female)
Reset (??)
Contrast ?
Back-right corner:
Mains in (probably!) - from power supply unit
19-w huge round connector to mate with power supply
Rear:
UHF socket
RGB (6-way DIN)
Cassette (7-way DIN)
Analogue (15-way D female)
RS423 (25-way D female)
Printer (25-way D male)
This sounds a bit BBC-micro like!. There is a Torch SCSI hard disk unit
for the beeb -- it's supposed to be rather rare. The one I've seen is a
plinth to fit under the nonitor contianing the SCSI interface (connectes
to the Beeb 1MHz bus) + hard disk and also a floppy drive (connects to the
normal Beeb disk controller). Maybe you have much the same unit built
into a case with the Beeb mainboard and monitor.
Torch-725
---------
This may be a Quad X machine; if so then there aren't many of them left I
The QuadX I have is in the same case (basically) as a production XXX. But
the mainboard is a singla 6U VME card, and there's a little 3 slot (I
think) VME cardcage in the bottom slice. Much the same PSU as a XXX.
expect! It is according to the previous owner, but it
doesn't say so on any of
the badging. Case is grey steel, about the size/shape of an IBM XT case. Data
sticker gives the model as a "725/U" and the serial as "84022913"
At the front we have:
2 x slimline 5.25" floppy drives
Hard disk led visible through window cut in the case
Power led
Whilst at the rear:
Reset button
Keyboard socket, 15-w D female
Phone-jack type connector (Mouse? Or alternate keyboard socket - I have
keyboards with both type of connector? Or modem?)
"RS423 #1" - 25-w D female
Parallel - 25-w D male
Blanked ports: "RS423 #2", "RS423 #3", "Extension bus",
SCSI, X25
Analogue port, 15-w D female
Torchnet port, 5-w DIN
RGB 6-w DIN
Mains in
Mains out
Switch (power I assume!!)
Large grille for cooling fan
This does not sound like a XXXX....
Monitors
--------
One of these should work with the 725 above, another with the Triple X
'prototype' I guess.
Single Torch Triple X 13" monitor, model CM13. 8-pin DIN input.
THis is actually a Sony Trinitron chassis...It works at TV rates and will
take analogue or digital RGB in. Works with the Beeb, XXX, XXXX, etc...
Two Torch Triple X 10" monitors, model CM10.
8pin DIN input
I've never seen one of these, but it should work, at least, with the XXX
Four Triple X keyboards; with 6-pin phone-type flat
plugs on trailing leads
and 6-pin phone-type flat sockets on back of the keyboard (for mice?)
Yes. Mouse connector. It's basically a special serial port. AFAIK the XXX
and XXXX take the same keyboard.
Torch Z80 disc pack - grey metal case for two
half-height 5.25" drives; it's
been stripped of drives but I think the psu is intact. I believe this needs an
interface card (which may well be amongst the cards listed below)
AFAIK the drives just link to the normal Beeb fisk controller
Triple X PSU (or so I was told; not having a
'genuine' Triple X I don't
know!)
Can you describe it? I've got a couple of XXXs (including a nicely
expanded one with a Quinring on top), and quite a pile of spares...
Tape drives
-----------
Possibly for Quad X? Anyway, there are a couple of 5.25" HH units; not given
In theory the XXX can support a tape drive on the SCSI bus, but I've
never managed to get it to work...
Three Torch Z80 Communicator boards. Z80A CPU on
board, 40 pin data
connector. Another BBC plugin? The owner had hundreds of them apparently and
most of them went to landfill a while ago.
This is the board that goes with the Z80 disk pack. It fits inside the
Beebm and connects to the Tube (I think). It runs CP/M (or something close
to it).
Unknown Torch Z80 card. 40-pin connector at one end,
26-pin connector at the
other. Z80A CPU and SIO chips on board, plus 6522A and an 8255 chip. ROM is
Torch labelled as CCCP V1.02
Sounds like an expanded version of the above, with a serial port.
Three Torch internal (internal to what, though?)
modems - 40-pin connectors,
plus 4-pin single-row for power. Several 40-pin chips: Z80 PIO, MC6803,
EF68A21P. ROM is Torch, labelled as "ADM5 2.1". Also a TM2016 chip on board
(memory I believe) and a 28-pin IC branded as "world-chip".
The 'world chip' is an AM7910, that well-know 300 and 1200/75 baud modem
IC. This sounds a bit like the Torch modem for the Beeb and XXX, but I
don't recall a Z80 PIO on that board.
Two oddball "modems". I don't even
know if that's what they are :-) 2x 4-pin
single-row connectors, 14 pin single-row connector, then a long trailing lead
terminated in a 5 way rounded jack plug. I've not seen those jack plugs on
anything before, but it's possible old UK phone exchange equipment might have
used them - anyone? There's very little in the way of logic on the boards -
Sounds like a 'Plug 95A' which was the standard UK telephone plug before
the flat 400 and 600 series. Commonly used on Prestel sets, etc.
it's all analogue. Boards are 6" x 7".
Trailing lead goes into a large white
plastic 'box' in one corner of the board. On top of this, apparently as an
afterthought, is a glued-on smaller black box out of which come two leads that
connect back to pins on the 14 pin connector. Hardware hacking at its best...
Right, the following appear to all be protocol convertor / interface boards for
various storage devices. All are on boards around 6" x 8" in size, and all
have
a single 4 pin power connector (I may have manuals for all of these; I haven't
got that far yet!):
Seven issue 3 Torch manta boards, for converting between SCSI and floppy
interfaces.
These are used in XXX and XXXX machines if you have a real SCSI hard
drive (as opposed to an ST506 one on an OMTI board).
Single issue 5 Torch manta board
Four OMT boards (model 5200) with a 50 pin connector, 2x 34-pin connectors
and 2x 20 pin connectors. SCSI (or SASI?) to MFM disk?
SCSI to ST506 and floppy. Used at least in the XXX.
Single OMT board with a 50 pin connector, 34-pin
connector, and 4x 20 pin
connectors. maybe SCSI (or SASI?) to MFM disk again?
Probably.
Four Xebec boards with a 50 pin connector, 3x 20 pin
connectors and single
34-way edge connector.
Single Xebec board with a 50 pin connector, 2x 20 pin connectors and single
34-way edge connector.
Sounf like SCSI to ST506 interfaces
Two Archive boards with a 50-pin connector at one
end and a 50-way edge
connector at the other.5 LEDs by the power connector. Tape interface of some
sort, presumably?
Take controllers, Probably SCSI to either QIC 02 or QIC36....
Single Emulex board, 2x 50-pin connectors at
opposite ends of the board. Hmm.
Tape again?
Single Adaptec board, 2x 50-pin connectors at opposite ends of the board.
More tape controllers...
Single Western Digital board (labelled WD1002-05),
2x 34-pin connectors, 3x
20-pin connectors, and a singe 40-pin connector. Only thing I can think of with
40 pins is IDE and it's too early for that I'm sure (last chip date is 1983)
I *think* that's all of it, for now. The guy I got these from had several rooms
piled up with stuff; he said he used to have a few 'proper' Triple X systems
and is surprised he threw them out, so they may still be lurking somewhere.
Same goes with other genuine Torch spares, drives, software, cables etc.
There was a Quad X-on-a-card which I had my eye on but the guy still uses some
That sounds like the production QaudX....
