In a shipment today I got several AMP-labeled dongles that look like SCSI
terminators ... except the 50 pins are arranged in three rows (17-16-17), not
the Centronics-style 50-pin connector nor the usual 2-pin configuration.
Anyone seen those before, and is it actually SCSI, or is it something else?

FWIW and as some of you might know, Polymorphic was manufactured here in
Santa Barbara (also Lobo Drives/Systems, and Street Electronics.) After
Poly had gone out of business, a friend of mine ended up getting all (or
most) of the remaining Poly documentation and most of the remaining
hardware from the person who owned the Polymorphic remains. After he had
sold off some of that "stash", he gave the remaining stuff to me. I
spent a week or so taking the remaining original masters documentation
and putting it in a filing cabinet. That stuff included approximately
200 S-100 boards in various states of being built and maybe up to ten
thousand (WAG) 1/4" and 8" disks of stuff that was being worked on at
Poly when they shut down.
On my to-do list is to scan the remaining documentation (about a four
drawer filing cabinet) as well putting together the remaining Poly88s
(four- six) and other boards. I had planned on bringing some of that
"stuff" to VCFMW, but found out last night the exhibit area was filled.
So at this point, I don't know if I will be attending or not.
I am more concerned with getting the documentation scanned and archived
and will most likely end up buying a high speed double sided scanner. So
this is just a heads up that a lot (most?) of the original Polymorphic
documentation does still exist. Years ago, some highly uninformed
individual said this could not be original since there were no graphics
in the Circa early 1970 docs. He was wrong about this not being original
documentation!!! I also tried to keep any marked diskettes with the
docs. Those disks were primarily system disks. And those disks NEED to
be backed up before they degrade to the point they would be difficult to
read.
FWIW, I would have liked to get this stuff scanned, etc but at that
time, I didn't have enough money to pay attention let alone buy a
scanner to scan this stuff :).

Regarding the Poly-88, I'm not seeing much about it on YouTube. If you've
got a working one, it would be good to "get one on record." If you're
willing to part with it or loan it - let me know (can also run it by
ActionRetro, although he's concentrating on some Russian imports at the
moment).
But back to the original topic, hope VCF West went well ! Looks like I've
been talked into going to the September 9th VCF near Chicago.

I'm sure there are at least a couple of you who will be attending the VCF
this weekend in Mountain View at the Computer History Museum.
Is there anything that anyone might want/need? Please send me a private
message if you're looking for something and if I have what you want I can
bring it with me.
I'll only be there Saturday.

I sold my Lear Siegler ADM31 recently and the new owner (Ian) has found
that one of the ROMs failed before he could archive it - or it was
defective to start with.
So my question to the list is - does anyone have the ROM codes (there
are three of them) archived?
I don't think Ian is a member of this list, otherwise I'm sure I would
have spotted a post with a subject line like mine...
Thanks!

Not really, though that's part of it. The value of the Apple 1 has more to
do with the Cult of Steve than anything else. Steve Jobs became the most
celebrated CEO of his time. He was practically a rockstar. Personally, I
think the admiration for Jobs turned into cringey idol worship, but the
fact is millions of people around the world were impacted by the products
Apple produced under his leadership, and he received the adoration.
As I said previously, the Apple 1 is now an icon, a status symbol for the
wealthy. The "Veblen Good" concept absolutely applies here. They have
transcended our motley little community of vintage computer enthusiasts.
They will continue to be held in high end collections for generations to
come.

There’s dozens of similar machines from the same time period, vcreated by startups looking to be the next big thing, that just didn’t make it. Look at SWTPC, look at IMSAI, the COSMAC ELF. Apple made it to the big time, and they didn’t, so many more people with too much money would consider the Apple 1 to be a wise investment.

Collection values are so subjective that to me, that they make little
sense. For example, is a Mac that belonged to Steve Jobs more valuable
than the same model Mac that belonged to Harvey Schmidlap? Same
machine--I doubt that any scientific test could affirm that Jobs was
still alive in the former. But the difference to collectors may be a
couple orders of magnitude.
But then, I see little difference in value between an original painting
and an expert copy.
Yes, I know, I have no soul!

My IBM 1410 FPGA project now features a working 1401 mode as well, with
the flip of a switch, exactly like the original IBM 1410.
There are still a few real problems (e.g., Console I/O Input under
program control doesn't seem to be working), a few minor issues
involving console problems when doing control operations, and lots of
changes I want to make to the PC console support program, which really
should be done before tackling I/O devices.
There are posts relating to the debugging of the 1401 side of things
towards the end of the list that appears on page:

I have a HiPlot plotter - it's DMP-29, but I'm fairly sure it takes the
same pens as the DMP-2 which I also have but in a million pieces - but
right now without pens.
I have been promised some but it may be many weeks...
I'm wondering if anyone has any old (or NOS?) pens for them? What I'm
after is the dimensions with a view to 3D printing new pens - or at least
pen holders so I can fit modern pens into. (There is no height restriction
on the pen bodys)
Can anyone help?
(I'm in the UK if anyone has any physical pens available - please
let me know)
Thanks,
Gordon
I have 3 of the 4 pieces of Modular Advanced Design's MAD-1 and every now
and again I like to reach out and see if anyone might have the last missing
piece I need. The MAD-1 is sort of like the evil twin of the Mindset..
although nowhere near the graphics prowess. Unfortunately like the Mindset
the disk drives are a separate unit and unlike the Mindset the MAD-1 can't
operate without them because the enclosure also contains the PSU for the
whole computer. The floppy drives are nothing special.. just SA-455 360k.
Anyway, Sellam's msg about trades prompted me to reach out again. If you
aren't familiar here is a link to a pic of one CHM has.
