I got the chance to attend another great VCF! This time in Chicago over
this past weekend.
Most images should be able to click and enlarge (if not, wiggle the page a
bit and try again).

I've started pulling parts for people who have requested them and keep
finding things I had forgotten. A few things of possible interest include:
PDP-8A parts including backplanes, most CPU boards, 128K, MM board MM8-AA/AB
8-E boxes and boards
DECMATE Rainbow, and PRO systems and parts
A few 11/05, 11/10 boxes
a new 54-21149 KN15 cpu
VS40X 4 plane color options
SI-QS 1000 board labeled QED 993 CPU
Tape drive heads
LA36, LA120, and other printers and parts
various VTs and monitors and parts
MFM and floppy drives
Qbus boxes and hundreds of boards
1000s of DEC boards and parts
possible a few 3000 and 5000 boxes and parts
If anyone wants to stop by and look for things, please contact me off list
to set up a time. Most of the people who have stopped by would say I have
quite a lot of DEC items.
If you have any questions contact me off list.
There have been a number of Ebay listings for various ns32k software, QIC
tapes and 1/2 inch tapes. I thought I would buy them if there were no other
bids to try to recover the contents.

But there was a buyer and I didn't want to fight over something where I
don't have the actual hardware. Maybe someone here is the buyer? I am just
curious if this will end up on bitsavers in the future?

Hi all,
I just bought a very clean, DSDD 8" disk drive off eBay and it has a 50p
connector which I guess is the common Shugart type? I also found a 50p->
34p adaptor PCB design someone documented online.
I haven't delved much into floppy formats (high level or low level) but I'm
somewhat familiar with filesystems from FAT12. My ultimate goal is to
create an open-source USB adaptor that reads/writes the contents of an 8"
disk but presents itself to an OS as a Mass Storage Device (block device).
Is such a thing possible?
I once created a terrible custom format for storing data on a flash chip
which required no low-level format, but I expect a magnetic disk needs
headers/trailers to know when a track starts/stops so it can skip around.
I checked out the KyroFlux website and it seems there are dozens of formats
that were used for 8" disks - is there a favorite format among the
community that allows full use of a 1.2MB 8" disk?
Any pointers are appreciated!

Some of you might recall that Apple released a series of machines based
on the Newton OS in the early 1990s. There were eight models in total
from Apple, and a few more from third parties who licensed both the
hardware and software to make eg. ruggedized handhelds, or "smart"
(landline) phones.
The operating system was bespoke. It had a Lisp influence during
development, but by the time it was released, it used a language called
NewtonScript that had an Algol-ish syntax with Lisp/Self-like
semantics. Although the OS core was written in C++, large parts of the
system were written in NewtonScript as well, as were the built-in
applications.
Newtons ended up as a dead-end branch of computer evolution. The
product line was cancelled by Jobs following his return to Apple, and
despite a few little respectful nods, iOS has basically no commonality
with NewtonOS. Ironically, the handwriting recognition engine (the
focal point for most Newton criticism) outlived the devices and was
ported to and shipped with Mac OS X.
A Newton emulator, called Einstein, exists. It's able to run the OS,
the built-in apps, and to install and run third-party applications with
good fidelity to the original experience. It requires a ROM image to
function. Apple made various ROM images available, and it's possible to
extract the image from a physical Newton device, but the consensus is
that it isn't legal to distribute these ROM images. This makes setting
up the emulator more complex than is ideal.
The NewtonTalk mailing list is a group of Newton fans that remain
engaged with the platform to this day, and we're currently discussing
the possibility of legally obtaining the Newton ROM images from
Apple. We've been heartened by Apple's recent releases of MacPaint
and the Lisa OS to the CHM, and are wondering if Apple might be
persuaded to release at least the NewtonOS ROM, or (ideally) system's
source code.
If there's anyone who was either involved in those previous
negotiations, or could introduce us to someone who was, and is willing
to offer advice and/or assistance with our quest ... really, any helpful
pointers would be useful, and much appreciated.
Cheers,
d

Hi.
Has anyone got SCO Unix to successfully install and run on Virtualbox?
My efforts have failed. My host is Ubuntu 22.04 with Virtualbox 7.0.10.
Thanks, Ken

I had heard he was in poor health due to a bad diagnosis but it's tragic to
hear he's gone now.
It was because his annual Free Stuff Days I was able to build up most of my
lab equipment. Those were the days when you could still pull up and fill
your car with all sorts of goodies. I bought my first real EPROM programmer
(a 29B) from him.
