If memory serves, my box has five HP-IB connectors. One is common and
the other four are swtiched.
In theory, the HP-IB can have up to 32 devices per bus but many of the
devices only have three binary switch postitions on the address switches so
you can only set them for addresses 0 through 7.

That doesn't help me any. I'm still on the opposite end of the country.

Ooh, two parts and you're done :-). (Sorry, couldn't resist. Of
course most of the cost is getting the gold-plated fingers on the PCB,
in my experience!)

I can't seem to find the ones I thought I had. If you could copy them
that would be a help.
At some point I want to do an IDE to omnibus interface, looks pretty
simple if one is a willing to take advantage of the 16 bit wide IDE
data (yes it wastes 4bits per 16bit word).
First thing I have to do is another 4k of core, the 4k I have is not
quite enough to work in. The alternate is to make a RAM card
using 32kx8 parts.

There is no photo, and here's the description:
"Applicon Mainframe For sale. Must be moved from current location. Consists
of one PDP11 Processor, reel to reel tape backup unit, 200 megabyte memorex
removable platter hard drive, 4 autocad terminals with green crts. System
was once owned by Fisher Motorbody and used to design car bodies. System is
two 6 ft tall standard 19" racks and the external hard drive unit. Each
terminal is a build in desk unit with the monitor mounted on a pole in the
back and sitting one foot above the desk area. Unit must be moved for the
space. Shipping must be paid by the buyer. Best offer and take it away."
There's only one bid for $10.00, no reserve, and the auction ends in about 8
hours. Does this sound like something that would be worth driving a little
over 300 miles to pick up? The PDP11 description leaves a lot to the
imagination. Does anyone know which PDP11 was used by Applicon?

Whilst I agree that I should have taken the extra few minutes or so of time
it would have required to email the "giver" and ask "where" to benefit
the would-be "givee", it's pretty obvious to anyone thinking about it for
a bit that I shouldn't shout my "mea culpa" very loudly.
I've now emailed Griff to ask him ... and I'll post any reply I get.
BTW, I have no idea how the @#$%^ text got so screwed up...it looked fine
in Pegasus :) It was probably MIME/rich/some-such, and I've noticed
infrequent problems with that kind of text. Sorry!

No, but could you use silver-loaded conductive paint? That's what we used
to use to repair the printed tracks on membrane keyboards (including
Sinclair ZX keyboards). I've used it for a few similar things, and at
least one type can be soldered to, with care, after curing. I used to buy
it in 3g bottles from R.S., part no 555-156, current stock number
apparently is 186-3593 or 101-5621, costs just over a fiver.

The fall (Las Vegas) Comdex show guide is about 500 pages of slick
material. It has contact info for exhibitors in the form of company name,
address, phone number, and a sentence or two of hype identifying their
products for over 1000 companies. It's a good way to find companies (as
kind of a worldwide yellow pages), or to keep track of who was around and
when.
One copy is free to anyone attending AT Comdex; sometimes it's easy,
sometimes hard, to get extras. Interface Group used to sell them by mail
for about $75
I have some extras to get rid of from most of the Fall Comdex's since 86.
$1 each (pickup here); or $5 each including shipping; or will trade a
dozen for the 1984 one.

The thread did. John W mentioned the RX8e and I commented on that.
He may have meant the RK8E.

I know.

Also known.

Same here! I'd like to get a RX8E or RX28E to use with my RX02.

No surprize. W9x filesystems (FAT16/32) have no real protections save for
the
samba box validating the connecting host has permissions. It's nature of
the
filesystem. NTFS is slightly better as the ganularity of control is like
unix in that
can restrict what is done with the file (readonly for example).
