Hey all -
I came across a big box of 12 of these disks which my dad acquired through
work back in the 70s, and squirreled them away in the attic after they had
copied the data. 4 of them have a broken metal access door. I opened one of
the broken ones (in a clean of an environment as possible) to see what was
going on inside. It looks like the door is held on by plastic divets that
have broken off. They might be able to be repaired with small screws. I
have no idea if these are functional or not. I am offering them up for free
for anyone that can use them. I'm willing to ship or you pick up in San
Diego.
Here is a link to photos of them:

It's been a while since i last wrote to the list. I have been reading up a
lot on early cnc systems.
While recently picking up some left over tech from a shutdown machine shop,
spotted a early cnc system with some kind of minicomputer attached. Looked
to have some kind of tape drive and paper tape punch. It looked like it was
stored under a leaky roof, ball of rust, it looked too far gone to salvage
anything useful.
Sadly phone was dead at the time and i did not get pictures.
Reading up on wikipedia, Data General Nova and Dec PDP 11 mini computers
are mentioned as used in early cnc.
Are there any surviving cnc systems, details, or software for the pdp 11?
I am interested to know a bit more how the hardware was interfaced. I have
pdp 11/34 systems for example, not sure if the external machine hardware is
directly wired into the unibus with a/d cards, or if some kind of external
hardware controller is driven by the pdp.
I have not found much info on any software used for this purpose.
Any accounts of how this worked or other interesting stories / info much
appriciated.
Thanks,
Devin D'Amico
Hi Everybody,
I am on the search for a Pulsar Electronics Little Big Board (STD Bus
Based) from the mid 80's.
My board has some very weird bus faults that I am trying to diagnose.
Having a working one would radically simplify my life.
I am located in Canberra, Australia, and am happy to pay for the board and
postage from Alaska if necessary :-)
Kindest regards,

I am interested in reading these and archiving the contents.
I restore IBM 1130 systems and am archiving software to be shared with
enthusiasts and museums.
Located in Florida so shipping would be necessary. Might need to be
creative to keep the cost of shipping reasonable.
The cartridges are not sealed, thus you can open them without a clean room.
The plastic hardens over the decades and it is not uncommon to have the
springy metal plate detach. It would be important to get the detached ones
out of the cartridge otherwise they could scratch the recording surface and
ruin the disk.
These have eight sector marks per rotation although the IBM 1130 hardware
skips every other mark to use these as a four sector disk.

Hi all,
My apologies if this is not the kind of "classic" computer people are
interested in but I have a Fontex Technology Group Prolite 206/16-047.
It is in good physical condition with the original case, mouse and
manual. It powers on but I don't have suitable disks so I can't get it
to boot. I can send photos of it if that's of use.
I'm trying to find it a new home rather than scrapping it. Is anyone
interested? It's currently in London and I would suggest collection
because it is not light but if there is someone who wants it shipped
and is willing to pay then I will give it a go!
Cheers,
- Martin
Back in the day I did a lot of playing around with the Radio
Shack versions of Tiny Pascal. (Back in the days when you
loaded them from tape cause we didn't have disks yet!)
I still like to mess with Tiny Pascal on other machines, too.
Now the bad news (at least for me). While I have my Model I
version tape I cannot find the tape for the Model III. Does
anyone have a copy of the tape or an image of the tape usable
on an emulator (pretty sure I can put that back onto a tape.)
I would really like to get back to trying some things with it.

I want to prep the outer shell of my new tandy model 102 for paint and
wish to remove the beautiful metal badgee from its recessed holder. I
considered using a heat gun but fear it may effect the plastic casing around
the badge.
Last thing I want to do is damage the badge. Any clues?

Alright, so the 3100 arrived yesterday afternoon and looks to be in good
condition visually. The voltages from the PSU look ok as well. So I plugged
things back in and powered it on.
I don't have a console for it yet, but it seems to go through some
self-test, the tape drive does
some stuff as well as the hard drive. It came with the slightly larger RZ25
rather than the RZ23.
I am getting some 6-conductor cable soon and will make a console cable
for it. I'm very curious
to see what it does on the console.
I have a SCSI CDROM coming in a few days. I also have an old SUN external
enclosure that I'll put to use for it as an external CDROM.
Interestingly, it doesn't have a model number on the sticker, but based on
what I have seen, and
the pattern of the connectors in the back, I am pretty sure it is a model
10.

One of the greatest joys of classic computing was running what you wanted
on your own computer. What has happened in the intervening years? Have
‘software walls’ created a computing environment that benefits software
gate-keepers(owners of computing technology) by monopolizing creativity,
freedom to program and establishing a defacto ‘true ownership’. Will the
future be this or will it be more like the earliest years of
microcomputing?
