If one codes a set of "micro" instructions in the Alter-Skip-Group as
follows:
LBL1 CLE,SEZ CLear E, Skip if E Zero
Instruction 002140, would not one expect this to always skip the next
instruction??? I would think E has been cleared, so the Skip if E Zero
becomes true.

Un-Ken-like? Well, at Modular he was in effect saying that he didn't want to
just retire and leave the stage, he wanted to keep doing what he loves, making
computers. If he chooses (or already chose, don't know if he is still alive or
not) to be buried/cremated when his time is up, then that's it. But if he opts
for cryosuspension instead, then he'll be revived some time later and will be
able to make computers again, this time for eternity, like a god of computing on
Mt. Olympus, eating ambrosia, drinking nectar, enjoying the goddesses (so
eternal life and eternal youth are never boring) and making VAXen.

BTW, is Ken still alive? Someone else mentioned on this list some time ago that
he is in cryosuspension at Alcor.

The pin spacing is 0.156 inch.
You can get the Molex parts at Digi Key. www.digikey.com
You can look up all the data sheets using the parts numbers at
www.molex.com.
The 10 pin right angle connector is Molex part 09-52-3101, Digi Key part
WM3307-ND. They cost $1.57.
The polarizing key is Molex part15-04-0219, Digi Key WM2402-ND. They cost
0.25.
The round pin male header is the Molex 3192 series. The 10 pin unit is Molex
part 26-20-2101. I have not found a good source, Digi-Key only carries the
square pins. The square pin has more contact area (a flat side instead of a
point.) The increased friction makes it more difficult to plug and unplug
boards.
I used the AMP part to build a motherboard (fartherboard?) The 12 pin
version is cheaper then the 10 pin version. I bought 12 pin parts and used a
utility knife to trim them.
10 Pin MTA 0.156 Header Assembly Straight Round Tin
Amp # 1-640384-0
Digi-Key# A24154-ND Price $1.37
12 Pin MTA 0.156 Header Assembly Straight Round Tin
Amp # 1-640384-2
Digi-Key# A26174-ND Price $0.93

Hi,
Does anyone have/collect any computerized point-of-sale systems?
I am specifically interested in 3 old systems from Tranti Systems Incorporated (now defunct, purchased by GEAC sometime in the mid 90s), the System 29, System 105, and System 2100.
The first 2 where proprietary hardware, the last was PC-based. If anyone has any leads on any info, please let me know.

Does someone know off the top of his head what the pin spacing is on the
SS-50 and SS-30 buses? Better still, Molex or other manufacturer's part
numbers for acceptable replacements (10-pin male and female)?
Thanks! --Patrick
Oh, I'm probably going to regret weighing in on this but: ebay proxy
bidding is MUCH better than a sealed bid auction because if you win,
you only end up paying one increment more than the second highest
bidder (usually a buck or two). In a true sealed bid auction, you pay
whatever you bid, which might be a lot more than the second highest
bid. So, the ebay model almost always gives you a better deal than a
sealed bid, and never a worse deal.
What most people don't like about sniping is the emotional letdown
they get when their bid sits at the minimum for a week, and then
their maximum gets exceeded at the last second. I have to admit, I've
ended up feeling cheated myself, as if I actually deserved to get a
PDP-8 for $10. But all they've cheated me out of is the opportunity
re-think my maximum bid after that find out that someone else may be
interested.
What would make eBay much more interesting (and more expensive for
buyers) would be the going-going-gone approach used by live auctions,
and the old onsale.com site. Real auctions stay open until bidding
activity has ceased for a period of time. Onsale kept auctions open
past the posted closing time until 10 minutes had passed since the
last bid. This made sniping irrelevant, but in exchange you could get
a frenzy of emotional incremental end-stage bidding.

Where can I get the original sgtty version for those who prefer sgtty to
termios? What OS is it for?
(I don't currently have a need for TU58 emulator, but hearing talk about
changing sgtty to termios just made me jump up and scream "I want sgtty!!!")

It's 80's vintage, analog XY pen plotter, there's a mylar low-compliance
drive belt, mine apparently stretched then dove into the drive gear,
ruining it beyond all repair.
Does anyone know where to get replacement parts? I have the old belt
(pieces) so I can get dimensions. (It's about 3mm wide, 2" diam,
yellowish thin mylar).
Pens are enough trouble to find, I fear for the machines life for lack
of drive belt.
(I tried fabricating replacements, it's a tight application; since it's
a servo closed-loop, I think grooving it for an O-ring will make it
hunt.)
