Unfortuantely, i'm looking to have to sell off a peice or two of equipment
to fundraise a bit.
I need to get rid of this stuff quick, preferably today or tomorrow. Paypal
or cash in person accepted.
The equipment is in Bel Air, MD.
NeXT system (complete mono slab monitor and all) - $250
Sun IPX/LX/Classics varios configurations ad requested - make offers
One each SLC and ELC available.
old in box TI-99/4a unused/untested - broke the seal on the inner packaging
to make sure all manuals were there. - offers requested.
IBM RS/6000 B50 - probably annyoing/tricky to ship. $50 - 512MB ram and
2x9.1GB drives mounted and ready to go.
NeXTstation color is available now, but will be pricier due to soundboxes/y
cables/etc required to make use of that. Parts available but in extremely
limted quantities.
And other various odds and ends such as 13W3 cables, scsi cables, etc.
This is a sampling of what's available - i'll add more if i can think of
what's worth listing. Inquiries for anything else in my collection you
might be interested in or wonder if i have - let me know.
Something new, as well
Dual Quad Xeon HP DL380 G5 with 10GB ram and 0 HDDs - $200

Can anyone tell me how to write a .DSK (JV3) image of Super Utility 4 for
TRS-80 Model IV to a real diskette?
The image boots in my xtrs80 emulator, but it cannot copy itself. If I
boot either TRSDOS 1.3 or LDOS 6, they do not recognize the image file as
a valid disk.
Sort of a Catch-22, yet I understand it is possible.
Terry (Tez) appears to have done so based on his web site writeup, but
it's unclear how the techniques mentioned (ImageDisk) apply to a
non-standard JV3 image.
I have the feeling the solution is obvious, for some definition of
"obvious", but I'm not seeing it.

Hi there,
I am looking for photographs or replacement parts for a Unitron U2000/Linden
Series One keyboard. It was working however in doing some testing with it I
think it blew the controller chip, which is a 2732 EPROM. I've changed all
the other chips with no success. Was hoping to find a reference photo just
to make sure I haven't messed anything up, or if possible a dump of the
controller ROM. Not urgent but hoping to get this running again someday
soon. Basically right now nothing works except CTRL-RESET
Thanks!!

What type of cable are you using?
I have seen two different styles of cable -
1.) Controller-to-drive.
Cable goes directly from controller into the drive itself with no bulkhead connector.
(RL connector on one end, berg connector on the other end)
2.) Controller to bulkhead adapter, then standard RL cable from bulkhead adapter to drive.
Ribbon cable goes from controller to an intermediate (bulkhead) connector.
(Bulkhead piece has a berg connector on one side, and an RL connector on the other.)
If memory serves, and you are using the bulkhead style intermediate connector,
an incorrectly pinned ribbon cable could produce similar results.
I don't recall if the ribbon cable is pinned straight through, or if one of the connectors is flipped.
Just a thought.

Re: PDP-8a Restoration/RL01 issues
Be sure you have the Berg connector on the controller oriented
correctly. You won't break anything if you don't, but the clock won't
get to the drive, as you're seeing. -- Ian

Hi!
I managed to netboot NetBSD 6.1.3 in my HP 9000/375.
Its external HD shows major failure (PCB, I suspect), so no local disk
by now :(
After some repairs, the 9121D passes all tests (confidence, and the ones
performed setting HPIB address and shorting the J7 test pin).
But when I connect it to the 375, I don't see the 9121 in the initial hw
list and I've not been able to figure out how to address it with NetBSD.
1) The SCSI/HP-IB and the HP-IB ports are equivalent?
2) The 9121 must be set to some "special" HP-IB address?
3) On the processor card, under the SCSI/HP-IB port, there's a 50pin
connector, which looks like a SCSI-50. Can I connect there a standard
SCSI disk?
Thanks!

Just a small update about what I have found so far.
1. The "FAULT" lamp on one of the drives was broken.
2. The solenoid on the other was jammed. This means that both drives
behaves the same.
3. There is no clock present from the controller.
Have to fix the controller first.

A few days ago I was doing my usual scan of Weirdstuff's inventory and
came across the following vintage Sun system:
1. Sun 386i. Looks clean - opened it up - memory and HDD controller
present - no SCSI HDD.
2. Multiple Sun-4 systems, part number 600-2157-01, Model 247. OEMed and
labeled "CADNET IX". I did not open them up - but look quite clean from
the outside.
If you are interested in any of these systems, email me privately and
I'll give you the contact at Weirdstuff.
Note: My only relationship with Weirdstuff is as a client and I do not
receive compensation for any item I mention on this list. I do this to
preserve vintage systems from being scrapped.
Regards,
Lyle

Yes, the white indicator with either a "0" or a "1" on it! It didn't
feel right.

About the cover, when should it be unlocked? Is it open when the power
is off (I suspect that it should be locked)?
The thing is that the cover is always unlocked on one of the drives,
on the other drive it seams like it's locked when the power is off.

I will check the bulbs and then check what errors that have been asserted.
