I'm not getting rid of my whole collection or anything, but things are
getting a little tight in terms of physical space and I have stuff that
simply doesn't keep my interest. I'd rather not do ebay so I'll offer them
here first. I will put up pictures if there is interest. None of this is
"barn stored". It has all been in my temperature controlled house since
last century.
1) HP series 100 (the 150 and 150 touchscreen II) documentation. This
could be described as the "grey wall" for the HP 150. All the basic books
plus Wordstar, Spellstar, Multiplan, etc.etc. At least 20 "boxed books".
Many (I think all but have not checked yet) have original diskettes. HP-150
with built in printer to come when I get back to it.
2) IBM PC original "boxed books"
a) "DOS" part number 6024001 on spine. I would call the condition
excellent. Two original 5.25 diskettes: DIAGNOSTICS Version 1.02 6081552.
DOS Version 1.00 6172212 (I'm tempted to keep this because of the CP/M -vs-
DOS controversy)
b) "DOS" part number 6024001 on spine with round sticker "1.10 with
Graphics". I would call the condition very good. One original 5.25
diskette: DOS Version 1.10 1502330
c) Four UCSD p-System books: Beginner's guide, Assembler reference, Internal
Architecture Guide, User's guide. The "User's guide" box contains five
original 5.25 diskettes: STARTUP, SYSTEM 2, SYSTEM 4, EXTRAS and UTILITIES.
3) IBM FORTRAN-77 Reference for the UCSD p-System "boxed book".
Contains one original 5.25 diskette: UCSD p-System FORTRAN Version IV.0
6936510
4) IBM COBOL Compiler by Microsoft "boxed book". Contains two original
5.25 diskettes: LIBRARY 6936566, COBOL 6172250
5) Various other original IBM PC "boxed books". Document Retrieval
Assistant, 3101 Emulation, Dow Jones Reporter, SNA 3270, etc. etc. Maybe a
dozen.
6) The box and binder for "Guide to operations, Personal Computer XT".
Unfortunately, it does not contain this. Instead it contains "The CP/M and
IBM Public Domain Library" by Dynacomp. This all seems to be later CP/M,
running on the IBM PC or Kaypro. Just documentation and listings, no media.
7) IBM Graphics Development Toolkit "boxed book". Three original 5.25
diskettes: VDI device drivers, Language Libraries, Supplemental Programs.
8) BASIC - Personal Computer - PCjr "boxed book". Contains original ROM
Cartridge "Cartridge BASIC" 1302285. (Maybe this should go with the PCjr I
will be offering when I dig it out)
9) ERGO MOBY BRICK 486DX-33 computer. Missing original power supply. I
cobbled together a supply last century some time and it worked then. Has
not been powered on in at least 25 years.
10) Osbone Executive. Limited Edition, personalized plaque to "ANNETTE
KING". It ran last century. Has not been powered on in at least 25 years.
More to come.

A friend has a PDP-11/40 for sale in New Zealand and sent me the
following information:
"I have a PDP11/40 for sale. It includes three (3) x RK05’s in various
states of repair, one (1) tape unit, one (1) A/D unit, spare parts of
unknown status, lots of disk packs, tapes and what looks like all of the
circuit diagrams for every card and peripheral in the machine, plus
RSK-11 manuals, some cobol manuals etc.
It was formerly used in the Wellington Hospital diagnostic lab,
presumably hooked up to some Lab machines there.
Note that it is 230v 50hz, so while the CPU may be easily changed to
your local voltage (I don’t know but I suspect it’s a transformer tap)
the disk spindles are likely to rotate at the incorrect speed if they
are clocked off the 50hz mains frequency.
The racks have been split to make it easy(er) to get out of the its
original location in a basement, and there is tape on the panels just
for shipping purposes. I removed the front panel for shipping to
prevent any damage, so it’s just installed temporarily for the photos.
They will be wrap separately in place in a box for shipping.
You can check out photo’s here:

This system will take time and patience to restore. As far as I can
tell everything is there, well maybe some of the disks have been ratted
for parts to get another disk working, but of course it comes with no
guarantees of any kind.
There are 8 cards in the CPU slots, plus five other cards that I assumed
to be tape controller, disk controller, A/D controller, plus memory x 2
or memory x 1 plus something else.
Keep in mind that all of the manuals, disk packs, tapes etc are boxed up
on a second pallet so there are two pallets for shipment."
Contact Brendan McNeill, Christchurch, New Zealand. at brendan(a)mcneill.co.nz
(I have no financial or other interest in this system, but would like to
see it go to a good home...)

...preserving the Data General legacy: www.NovasAreForever.org
hello cctalk! i have been working for the past few days on a DECmate II with what i believe to be an ailing RX50. i have a gotek with updated flashfloppy firmware, but for some strange reason i have been completely unable to get the DMII to boot a floppy image from it.
i have been trying to convert the OS/278 and WPS images on the dbit and ibiblio archives into a working format for the gotek but none of them will work. at this point i have tried too many conversions to recall but they all result in the same blinking floppy icon when the unit boots. i have “host = dec” in my FF.CFG per the wiki.
has anyone else been able to get this working? if so, could you please provide known-good images for a gotek, or the steps to generate them?
thank you in advance!

Got interesting stuff to sell? Let me know!
Looking for DEC, IBM, CDC, SGI, Data General, and more!
For cleaning and maintaining floppies give shadowtronblog on YouTube a watch. He lovingly restores various vintage equipment. There are a few vids of him restoring some floppies, cleaning heads, greasing mechanical bits etc. I think his TRS80 playlist had a fair bit of that in IIRC.
When reading old floppies, how often is it advisable to clean the drive? I managed the first 3.5” floppies no problem, I’m using a USB Floppy Drive hooked up to my Mac Laptop, I was able to image them using “Disk Utility”. The next two floppies have had errors. Though I think I was able to successfully copy all the files off the one.
Also, what is floppy drive cleaning fluid made of, and how well does it age? I know I’ve got at least a couple cleaning floppies around here, but they’re *OLD*.

Do I really need a torque spanner? Chinese spanners aren't expensive. But I'm not sure the unit even works (the mainframe seems to work fine, not so sure the ancillary test set). Hp 54120a + 54122a << iirc, maybe 54121a??? In any event if working this is either a 12ghz or 20ghz setup.
2 x 16" Trinitrons, missing rear plastic covers
1 is a 98789a 64hkz, forget the other, 48khz
1 x 19" large rectangular color unit, doesn't work.
I'll be tossing these before very long.
This may be a larger conversation than I intend but how would you all
generally start if you ha backup tapes that you wanted to try and
read/restore?
Supposedly they're Amiga qic tapes. I'm a little worried about the
structural integrity of the tapes. Not knowing what software was used,
would this be a literal job for something like tar via a Linux system? Then
see if I can interpret the dump and sort out files afterwards?
I might see if a local group wants to help play with this effort since I
think I only have 1 drive in unknown condition.
Hello everyone I’m a young collector (18) of 60s and 70s minicomputers and micros. I have been restoring a PDP-8L and would love to find ether a Diablo series 30 or Dec RK03 removable cartridge drive to go with this system. I am in the uk South Yorkshire to be precise and would love any leads anyone could provide on where I could find one would very much appreciated. If nobody know where one of these drives can be located any means of mass storage for a pdp 8L and data general nova system will be appreciated since I want to move my collection forward and have the systems set up with full period setups.
Thanks very much in advance.
Jake
