Hi.
I picked up a 35lb load of mostly Mac-related cast-offs last night,
and scored many cool objets de junque.
The 2 things I can't really identify are a Panasonic Easa-Phone,
KX-T1225 which seems to be a speed-dialer of some sort. The other is a
cable with a (Doc ducks & prepares to rub) 36-pin Centronics connector,
plus eyelet ground, on one end and a female card-edge connector on the
other. The shrouds are steel, squared, and embossed "TANDY" on both
ends. While I've never seen one, I'm guessing it's a Tandy printer
cable.
The rest of the haul is mostly OT, but see gimme list below:
working SyQuest 88MB drive & some cartridges
cordless 3-button mouse
a whole bag of the fabled 800K floppies
2 copies of FWB's Hard Disk Toolkit (one is even on-topic, I think.
System 6.0 bootable disk) The newer version came with docs
CharisMac Anubis that I can't date, but there's NO version info in the
docs, copyright is 1989-1996
Astarte Toast CD-ROM Pro v3, in original box but no docs
Adobe PageMill v2.0, no docs no key
Adobe Photo Deluxe no docs
Adobe Illustator v6 no docs no key (Waahhh!!!)
A couple of NuBus ethernet adapters, one with its right-angle adapter
A loose right-angle NuBus adapters with *2* female connectors
several Apple-AUI/10B2 transceivers
14400 (no AC adapter) SupraFax modem (needs 9V AC PSU)
33.6 SupraExpress modem with all its parts
GeoPort Telecom Adapter - first one I've found in the wild
2 28.8 SupraExpress modems, intact
1998 revision of the "Mac Upgrade and Repair Bible" with its CD.
Not bad for free. The transceivers, the 14.4 modem, the Tandy cable
and all the NuBus cards are all up for adoption; the rest is probably
available for trade if you need something.
All this because I gave $35 for a PowerBook 145B I didn't want and the
QuickTake 150 (with all its docs, disks, and a NIB Battery Booster Pack)
that I did want last week. Yee Haw.

That's the general description of the parallel printer cable
to the Tandy 1000-series machines before Tandy switched to a standard
connector on the CPU. I've got one here with my 1000HX.
Unfortunately Tandy used a number of different connectors for the
parallel ports of their early machines, including a dual-row header
and the above mentioned card edge connector.

Card Edge connector was the parallel port of choice on model 1's, 3's and
4's and vertain model 1000's. Also IIRC the mod 2 , 12 and 16 may ahve had
a card-edge parallel port.

Just pulled both my Tandy 1000 cable and my 26-1401. The
1401 is still in it's display bag and shows it is for the Model
I/III/4/4P/4D. It is a 6' ribbon cable, with the card edge connector
on one end and the centronics-style connector on the other. My Model
1000 parallel cable carries p/n 26-289 and the connectors LOOK
identical, though the cable and connectors are shielded vice being a
bare ribbon cable. This cable is a 6' cable meant for non-Tandy
printers with an IBM-style interface.

I have a Radio Shack 5 1/4 external FDD (mod. 25-1060 ) which I believe
was only useable on some of the 1000 models. Certainly not on my 1000SX
in any case. It has a 26+4 card-edge connector. Radio Shack seemed to
have some unique(non-standard) ideas for their cabling.

Even their internal floppy drives deviated from whatever
connections most others were following at the time. The drive you're
referring to above is the external 5-1/4" drive intended for use with
the 1000EX and 1000HX systems. There was also a similar drive with a
DD 3-1/2" mech for these two systems. On my 1000HX I used to put my
BBS online for testing using only the internal 720k drive and the
external 360k drive. It was a handy way to give people a means of
transferring private files directly too me too. I believe the
external 720k drive was p/n 25-1061. I didn't aquire one of those
until years later.

Since several of their printers were made by Centronics, even though

close as we can get to a correct usage!

Speaking of these, I located a blue ribbon cable with a card edge on one
side, centronics on the other - I beleive it was for a Tandy printer on
possibly a model 4. Been in storage for years and anyone that wants it can
have it for $1 over the cost of mailing (should be very light, probably can
go first class mail). The $1 is to cover what I gave for it. It's small
enough that it could even go outside the US cheaply. Contact me off-list at
rhblakeman(a)kih.net if you want more info or want it. I have to get a money
order in US fund s for it, or Paypal for the amount plus a buck for the
Paypal fee (it would be $2 plus shipping in that case, still cheap)

Not to be picky (well, OK, I do tend to be :-), "IDC" stands/stood for
"Insulation Displacement Conector", which meant virtually ANY crimp-on
connector, INCLUDING the card edge connector on drive cables for 5.25, and
the computer end of model 1,3,4 printer cables when they used ribbon
cable. Since the "centronics" connector (Amphenol Blue Ribbon 36
pin) wasn't very available in IDC, those cables were kinda hoky, with
either a non ribbon "centronics" soldered to ribbon cable, or a card edge
crimped onto spread out non-ribbon cable.
The one model 2 cable that I remember using (20 yrs ago) did NOT have IDC
connector. It was a round cable (I don't know whether it was shielded),
with a 20 pin dual row header sloppily put onto the end.

Well, my model 2 printer cable uses one of these, as does quite a number

box somewhere that I got as part of a bulk deal. They seem to be very
common for printer cables for Tandy and Apply computers made around
1983-1988. (I don't remember if the box I have is full of male or female
36 pin connectors, however.)

Actually IDC or "insulation displacement is not crimp on always - punch
block points on telephone blocks are IDC, as are many RJ45 blocks and
Schotclocks - it simply means any connection that does not need to be
stripped prior to making or attaching - many crimps need to be bare wire
first. They displace the insulation upon installation to make the
connection. There are screw terminals in many telephone network interface
boxes now that are made with a sharp ridge that when you screw them down
they cut through the insulation but too hard cuts the wire as well.
Most insul displ contact pooints are best done with solid wire although many
ribbon cable IDC's are the guiding type that cut into the insulation on
stranded wires of the ribbon cable.

Well, I just unburied my mod.2 and the parallel port is a double row 34 pin
connector and used a ribbon cable. I just recounted the pins and it is indeed
34 pin. It's interesting to note that the HD and FDD had the same type of 50
pin dual row connectors.
The display on the m.2 was also really excellent compared to other
computers of that time.

I'd have to pull my Mod III or 4p but I believe there's a
difference between their card edge connector for the parallel printer
port and that of the 1000-series machines.
Model 2 and 100 used a dual row header, and of course,
the PC clones used
an "RS-232 connector" :-)
The dual row header was also used by the Model 2000 and the
Model 102. Interestingly, they both used the standard DB-25F
connector for the serial port. Given that Tandy's PC-clones were the
1200, 3000 and 4000 series machines, I would doubt if any of them
used anything other than the standard connector. It was the original
TRS-80 line, the 2000, and the 1000 series that tended to deviate.
Anyone here have a Tandy 5000MC? There's a MCA-bus machine you don't
hear much about.

I'd be VERY interested in knowing WHAT differences
there are. The 26-1401
fits a "standard" 34 pin card edge, just like the floppy drive (RS had
lots of problems with people connecting things to the wrong port!)
There could be pinout differences that need to be buzzed out.
I no longer have the pinouts for the various TRS-80/Tandy
printer ports. I've got the pinouts for the 1000HX and the 2000, but
that's it. The 26-1401 isn't keyed at all either so it'd be easy
enough to plug it in upside down. The later shielded cables for the
1000-series have 'Top' embossed on the metal shield around the
connector.
Somebody said that there were different cables for
Non-Tandy
printers. I'd be very interested in more detail on that, since the only
difference that I remember was that RS configured all of their printers
for auto LF after CR, but that they were otherwise completely
interchangeable, and "standard Centronics port".
The links to Tandy's own documentation suggests the need for
the different cables depending on what printer type is used. Some of
their later printers did have an option switch which did allow you to
choose between Tandy and IBM modes, afaik. Maybe it was something as
simple as the LF and CR being different. That's been enough of a
difference to cause problems with text editors and such between
systems in the past.

The model 1 expansion interface had every cable go down from the
connector, and had silly little covers for the openings to go over the
cables (I have a new unopened set of those for sale)
If you leave off the silly covers, then any of the cables could be
inverted. You could also connect the printer to the floppy port, etc.

Several of the Tandy printers used a 4-bit interface, which is not

connector, which caused allot of problems.

And I can't think of one machine that used a '4 bit interface'. They all
have the conventional 8 data lines, strobe, and busy. Tandy did do some
unconventional things with the other, lesser used, handshake lines at one
point, but I've used non-Tandy printers with the M1, M4 and M100 with no
problems.
What machine and/or printer are you thinking of?
I was referring to bi-directional parallel communication on a model 1000.
This is most often needed for laser printers and most newer printers.
Rather than duplicate the information someone else has already documented,
I'll just provide a link: http://www.oldskool.org/~tvdog/1kfaq.html#II.H.5

But data output to the printer was still done 8 bits at
a time using the
8 data outputs. Are you sauying the Tandy 1000 didn't do this?
Supposedly the 1000's have a problem dealing with later laser
printers and such on their parallel ports. I myself always ran
fairly old dot matrix printers off of mine when I was using them, but
wouldn't think it'd be any more of a problem than other XT class
machines without the enhanced parallel ports that many current
printers depend on.

Wow! I don't remember those.
All the ones that I can recall were either "standard" "centronics"
(other
than autoLF),
or "almost RS232", some of which used a DIN connector for ease of cabling
to a Coco.
Once, when RS was was being criticized for "deviating from standards",
they said that "RS232" stood for "RADIO SHACK 232", and that
therefore,
THEY could set the standard to anything that they wanted.
difference
that I remember was that RS configured all of their
printers for auto LF after CR, but that they were otherwise completely
interchangeable, and "standard Centronics port".
Several of the Tandy
printers used a 4-bit interface, which is not
Centronics compatible. The printers did mostly use the same 36-pin
connector, which caused allot of problems.

I bought about 6 similar cables about a year ago. They might be a later
version of the same cable. They don't have a metal shroud on the card-edge
end, but do on the 36-pin connector. If I remember correctly, they are for
Tandy 1000 machines. The only other Tandy machines that I can think of
that used a card-edge for a parallel port were the TRS-80 models 1, 3 and
4.
Btw, I was told that Tandy closed the Houston located Radio Shack Outlet
store. Does anyone here know if that's true? They were a good source for
old Tandy/TRS-80 cables, and I bought tons from them.

It's a printer cable for a model 1000. I looked through the cables I have,
and I found 3x 22-222, and 2x 22-1259. They look identical, but based on
the information I found in the Tandy 1000-series FAQ they are made for
different printers. Theres no way that I know of to identify this cable
without pinning it out.

The printer cable I have with my 1000HX has a yellow band on
it with Tandy p/n 26-289. This is the cable for IBM-style printer
interfaces, vice Tandy interfaces which used p/n 22-222, among
others. The following links go to Tandy documents talking about the
choice of printer cables:
http://support.tandy.com/support_accessories/doc4/4263.htm
http://support.tandy.com/support_accessories/doc4/4000.htm
The cables are for the 1000-series, except for the RL, RLX, and TL/3.

I picked up a 35lb load of mostly Mac-related cast-offs last night,

Quite right. Also usable on the Morrow MD-x series if you pay attention
to the location of the ground contacts. IIRC, it goes on the MD card
edge upside down.

The rest of the haul is mostly OT, but see gimme
list below:
working SyQuest 88MB drive & some cartridges
cordless 3-button mouse
a whole bag of the fabled 800K floppies
2 copies of FWB's Hard Disk Toolkit (one is even on-topic, I think.
System 6.0 bootable disk) The newer version came with docs
CharisMac Anubis that I can't date, but there's NO version info in the
docs, copyright is 1989-1996
Astarte Toast CD-ROM Pro v3, in original box but no docs
Adobe PageMill v2.0, no docs no key
Adobe Photo Deluxe no docs
Adobe Illustator v6 no docs no key (Waahhh!!!)
A couple of NuBus ethernet adapters, one with its right-angle adapter
A loose right-angle NuBus adapters with *2* female connectors
several Apple-AUI/10B2 transceivers
14400 (no AC adapter) SupraFax modem (needs 9V AC PSU)
33.6 SupraExpress modem with all its parts
GeoPort Telecom Adapter - first one I've found in the wild
2 28.8 SupraExpress modems, intact
1998 revision of the "Mac Upgrade and Repair Bible" with its CD.
Not bad for free. The transceivers, the 14.4 modem, the Tandy cable
and all the NuBus cards are all up for adoption; the rest is probably
available for trade if you need something.
All this because I gave $35 for a PowerBook 145B I didn't want and the
QuickTake 150 (with all its docs, disks, and a NIB Battery Booster Pack)
that I did want last week. Yee Haw.
