Poughkeepsie would be good for me too. There's always the Hamfest in Augusta
NJ in July. Last year they had a few Octanes and some Apple IIs. I work the
vendor gate and get to see a lot of stuff before it goes on sale....

Many thanks to whomever suggested NetBSD for my QIC02 support problem.
I've been a long time user of Linux--my last contact with BSD was back in
the 80's on a VAX--I think it was 4.2BSD.
The last few years, the rot in Linux has been getting to me. It seems that
every time I want to do something a little off the beaten path, it's a
matter of Googling for "who else has this problem?" and finding patches and
putting up with careless distros. And endless bloat implementing things
that I didn't even dream that anyone could want.
NetBSD (I installed 2.1 to be safe) is the way I remember Unix--no-nonsense
and no-frills. The kernel compiled with what I wanted on the first try. I
haven't installed KDE yet, but it looks to be pretty straightforward.
The surprise is how well NetBSD functions on a lowly Pentium 166.
Compiling the kernel is a matter of saying "make" just before you go to
bed.
Cheers,
Chuck
OK. The models from the LX100 and up do have a cutom Intel "Hornet" chip,
but it is an 80186 at its heart.
There is a block diagram of the Hornet at
http://www.daniel-hertrich.de/200lx/block.pdf. There is more about the
Hornet at http://www.daniel-hertrich.de/200lx/, about half way down the
page, under the heading "The Hornet chip (CPU) and block diagram".

But Bob is right about the 95LX -- I have one of those and it *is* a '186.
whos AD? It seems the PS2 model 25 has something
similar also (G171?). I was hoping there was nothing
but off the shelf stuph on this thing. I have an IBM
PGA card on the way - does that have a crt controller
also in addition to an 8088? Seeing that these things
may have formed the basis for the VGA, what other
cards/systems have them? I would really appreciate the
data sheet if you can find the time.

The cables are straight through 50 pin ribbons. IDC edge connector on
one end
(same as 8" floppy connectors) and .1" socket on the other. I've seen
normal
flat used on short runs and "twist and flat" 25 pair used on longer
runs. 6'
or so should be fine with the standard flat grey stuff. The coupler
manuals
limit the length to 25'
134.5 baud was the exact baud rate required to match the motor speed of the
main shaft in the selectric mechanism. At that speed, the printer main
shaft clutch would remain continuously engaged. At any other speed, the
mechanical wear would destroy the mechanism VERY quickly. Obviously, with
buffering and handshaking one could use a faster rate externally, but that
speed was essential at the mechanism level.
All selectric mechanisms, at the mechanism level, use tilt/rotate code. You
tilt the ball to select a row, and then rotate it to select a column, then
whack the paper through a ribbon (it's a mechanism that Tony Soprano would
love). That is simply how a selectric works, and any other code will
ultimately get converted into tilt/rotate before being applied to solenoids
in the mechanism.
> What interface should I be looking for to hook it to the UNIBUS ?
Some variation of an unformatted tape drive interface. They are slight
variations between vendors, so you need the right edge connector to idc
interface card at the drive. There should be some indication of who made
the interface card on the PC board.
The three connectors are read, write, and control.
Unibus controllers often are either a system unit or a single quad board
with a second board for 1600 BPI PE support.
The Emulex TC11 and Western Peripherals TC-131 manuals are up on
bitsavers
Plessey and Dilog made similar controllers.
at the BARC hamfest in the tailgating area. Along with
a couple of DecWriters. Not Teletype badged, one was IBM
badged the other was badged with some local company. They
were still there at 11:30 am.

(M) is a mask mark, like (C)
INMOS high speed RAM, 35 nanosecond access time.
Probably used for a color lookup table before the DACs.
Was thinking about the previous day when I watched the ARPAnet
documentary, and was drooling over the blinkenlights of the IMP and
TIP...
Anybody in this list has either an IMP or a TIP?
Or even an unmodified H516?
Wonder what exactly are the differences between a virgin H516 and an IMP?
Heck if we have 2 of those IMPs, we could string a 50kbps line, and
build Internet2 all over again! :-)
