I pulled some RA60, R80, R81, etc. prints and manuals earlier, but left
them in the basement when I came upstairs.I will bring them up tomorrow and
put out a list.
Thanks, Paul

Correction to the referenced post - the Keys SDS systems did not come from

Hi,
My pal Dave just gave me a very nice original Ultra 1 Creator! Found a
nice 1K 146GB disk and 1GB genuine X7004 Sun RAM from good old MemoryX
and this store I'd never used before called DiscTech (great ecomm site and
decent prices afaict), so this baby's shaping up to be a fantastic and

That's true today, but probably not in the near future. Persistent
It is funny that the most common memory used today is a DRO type memory. The
read destroys much of the charge on a DRAM cell, requiring a write back of the
data.

You are probably right about the 6809, the stuff I worked on was all in

A collection just came to me. These are the original disks, with whatever
labels are on them.
As a set. First come first served.
If you are in San Diego I’ll arrange a swap with you locally.
If remote, we can arrange shipping.

More widely known as Telidon despite it being called NAPLPS.

Professional 350. I can't find this online and I was wondering if anyone has

Thanks

It was called teletext despite the implications, at least here in
Canada. People just couldn't get their tongue around NAPLPS!
It looks just like the teletext systems I worked on, maybe ours was
better than yours?

Apparently not for long. The 1107 was a thin-film memory machine, but
the 1108 et seq. was not, IIRC. At least I don't recall any mention in

I don't know much about plated wire store, but I do know it was used in the
Manchester University MU5 computer which pioneered heuristic pipelining.

I remember an IBM engineer talking about this at our ham radio club. The
wire was coiled inside a drum and pulses were sent down the wire. The
'read head' was a magnetic pickup at the other end of the coil - and
access time was however long it took the pulse to arrive at the other
end.

I was just listening to a video on the Voyager space craft. It used an
interesting type of memory, called magnetic wire memory. There is only a little
bit of information of it on the web. It is clever in that has a non-destructive
read. I just wondered if any one else was familiar with this

It's not Teletext, unless that word means something different on the other side
of the Pond. Teletext was basically a text system (the hint's in the name)
Hey guys.
Thanks for the tip. I opened it yet again and inspected further under a
