Probably a stretch but wondering if anyone has any info (manual, pinouts,
service documentation) for a GNT model 3601 8-bit (1") paper tape punch.
It was probably better known in the CNC / automated machining world than
in computing but my hope is to resurrect it as a backup punch for copying
tapes I use with my ASR-33 and thereby save wear on the -33's punch.
The unit has serial and parallel interfaces on DB25 connectors but I do
not have any pinout information for those. The serial one I can probably
figure out.
Unfortunately, the unit is a little more sick than "works OK" seemed
to imply from the eBay seller. It has what I believe to be a power
supply problem because as soon as you try to punch all eight holes with
the front panel test button, the power LED dims and the punch jams,
apparently from lack of umph to complete the mission. It could also be
jamming to start with and that causes the power drop I suppose.
In any case, looking for any docs before I open it up and start digging
around. I have written to GNT without a reply so far.

Hi folks,
anybody interested in buying the following?
- Omnibus core memories (tested good)
- M8350 TTY interfaces (tested good)
- RK05 disks for pdp11 (12 sectors) (used, new, tested, untested)
- RK05/RK05J/RK05F disk drive (untested, tested good, broken)
- RK05x spares
- TU56 DECTape (tested working, untested, broken)
- TU56H single DECTape
- PC05 paper tape reader/punch
- Some other Omnibus cards
PDP8/M
*******
A PDP8/M computer. Very nice (near perfect!) condition front panel. Chassis condition lower medium
condition. Backplane and PSU (220V) ok. No top cover. System configuration to be discussed. First
guess would be 12K core, TTY, CPU - all tested stuff.
PDP8/L
******
PDP8/L minicomputer, untested, keys bleached out by sun. Untested (really untested, currently don't
have the time to repair the machine) but complete with the 4K core stack. 110V
Keys kan be used from a pdp8/e - they're the same. But not from pdp8/m. Those have the wrong colour.
The PC05 is a strange machine: The reader portion of it was used on a pdp8/e (PC8E interface).
Normally you use PC04 for pdp8 computers. The reader part seems to be compatible. The punch part is
untested. Mechanics look fine. I guess that there are also missing boards on the punch side. Nice
condition though. No cover, 110V.
Location: Northern Germany (Hannover, Kiel).
Open for reasonable offers. Can send packages up to 30kg. TU56 can be shipped in two packages.
pdp8/m fits a package. 8/L cannot be shipped internationally.
Kind regards,
Philipp

Hi,
Are you still there in 2010? :-)
I need to read data from my friend's old Toshiba PC with HDD 26 pin
connector. I would need to know what are the signals, or what is the
adapter.
Could you provide some schematics?
thanx

Nice! You'll be able to put together atleast one really nice 11/44 from
that. I notice one FP11 in the list.

Just what it says, Network interface XOR and CRC block check option. :-)
Ok. The long answer then... You know about CRC-16 I assume?
This is hardware to generate that. You shove data to the card, one word
at a time, and you can read out the CRC value.
This card is, however, not very popular or useful, since software CRC
routines are actually faster on the PDP-11. DECnet can use this card if
you have it, but it's recommended that it not be used for this fact.
(The card is actually more generic, and can be used to generate any kind
of CRC checksum, not just CRC-16.)

No clear idea about those two...

I have an Apple Lisa 1 for sale. Yes, it has the Twiggy drives. It
includes the Twiggy systems OS disks (2), original Lisa 1 manual,
keyboard, original Lisa (rectangular button) mouse.
It works.
Excellent condition.
Normally I would not so brazenly hawk something but I need to raise funds
for an imminent move of the VCF archives.
I'm entertaining any and all offers. At a minimum, there should be three
zeroes before the decimal point.
Please contact me directly if you're interested. Photos and more detail
will be forwarded upon request.
Will ship galaxy-wide.
Thanks!

Does anyone have some info in the Texas Instruments SN75413 ? I am
trying to restore the front panel controls of an early Tandy Radio Shack
hard disk (8 MByte!), but cannot find this chip info. The reverse
engineered diagram is at
http://www.xs4all.nl/~fjkraan/comp/trs80m2/driverboard.png, but as I do
not have the pin functions, I cannot connect the lamp and switch part
(this bit is missing) to the board.
There is some info on Radio Shack hard disks online, but not for this
old model. For some more context of the board see
http://www.xs4all.nl/~fjkraan/comp/trs80m2/8megDisk.html.

Hi guys,
I'm toying with the idea of doing an MFM/RLL hard drive bolt-on for the
DiscFerret (seeing as the DF hardware is basically done now -- I'm just
doing a final design check before I send the PCBs off for manufacturing).
Problem is, I don't have a drive to play with.
Does anyone have any or all of the following kicking around?
- MFM or RLL hard drives. I could do with one or two of these;
anything's good, as long as it has an ST506-style interface (that is,
straight MFM/RLL with no funny business) and is believed to work. I'm
ideally aiming for something "of reputable manufacture" -- so not a
Kalok Octagon!
- Cable kit for the above. So that's the Data and Control cables --
edge connector to IDC plug.
- MFM/RLL controller to match the drive. Anything goes here -- e.g.
Western Digital WD100x series, DTC, Omti... as long as I can make it
work with the drive for long enough to format the drive and 'dd' some
data onto it. I'll even consider SCSI-to-MFM bridges if they can be
relatively easily tied to a modern PCI, PCIe or USB SCSI card (say, an
AHA2940).
I'm happy to pay reasonable market value for the above, but that doesn't
extend to paying ?390 for drive-on-its-own (read: drive that's had the
PCB removed and is basically useless) on "that online auction site"...
Thanks,

Hi,
I just came across this and it's pretty cool. Some has built a somewhat functional 1/10 scale Cray-1 using a Xylinx dev board. Here's the link: http://chrisfenton.com/homebrew-cray-1a/

has anybody tried localtalk bridge (
http://docs.info.apple.com/article.html?artnum=60290 ) in their mac setups?
I was thinking of taking one of my old LC slabs and throwing a $10-$20
ethernet card in, throwing a phonenet dongle on the modem port, either
loading the hard drive with a low os with all but the needed extensions and
files removed, or the same on a floppy, and just using it like a router,
with its only purpose being passing data between the apple ethernet segments
and the apple phonenet segments(which at this time is only my SE as every
other mac has ethernet).
