Chris Lindblad? Sorry, I'm drawing a blank on someone with those initials who
is connected with the LINC.
From: Jon Elson
Wow, those were fairly rare back when, and now there
may only be a
couple in existence.
Yeah, that's why I was hoping that someone connected to this community would
get it, so we don't lose track of this rare artifact.
I'd buy it, but i) it's not a PDP-11, and fails my 'PDP-11's only'
test
(intended to put a strict limit on the amount of junk I accumulate), and ii) I
already have a whole bunch of PDP-11 gear I have yet to get to. :-( There's no
way I would ever get to it.
Two complete CPUs, capable of running at the same time
in shared memory
(I think).
The documentation (1967 Small Computer Handbook) is unclear. It is clear that
the general mode of operation was for only one CPU at a time to be running,
but that appears to be to simplify programming (although it does say that "In
the PDP-8 mode, the LINC subsystem is disabled"). The memory is indeed shared;
it's on the PDP-8, and the LINC gains access via the standard PDP-8 'data
break' (i.e. DMA) mechanism.

I can say over the last 30 years or so, I enjoyed a number of
exchanges with CJL.
I did enjoy the repartee - iirc most of it was just between us, but
some was in some 8 related channel.
I found him knowledgeable, opinionated, but most of the time just
plain fun to argue with.
Over the last 6 or 7 years, sparse contact, but always remembered fondly.
Sorry to see him pass.

Oh wow, I just realized what you're talking about here....I spoke with him
on the phone two months ago...He said he was not well but he did not
elaborate. I did not know him well but I am sorry to hear this happened.
From what I knew of him, very knowledgeable and
passionate about the PDP
8. He said he had his own OS that he wanted me to try out,
I hope someday
to get a copy of the RK05 boot pack.

Charlie Lasner passed from COVID-19 on 03 Apr 2020. He was still
perfecting P?S/8. We've managed to image his non-password-protected
computer drives in an attempt at recovering P?S/8.
Assuming that we're successful _and_ his widow gives permission, we'll
make it available "as is." We'll also have his documentation (that he
wrote & used before writing the code) and make it available too. When
bugs turn up, hopefully skilled users will make corrections and share
them -- perhaps on GitHub.

Charles and I have many emails over the years going back and forth regarding
OS/8 vs. P?S/8.
He was one of those folks that when you sent him a five line email, you would
often get a five page response. Charles was definitely opinionated - but often
proven to be right.
Both Charles and Merrill (author of FOCAL) teased me when I got my PDP-8/S
running. It was definitely SLOW (8/S where S=Slow). Merrill told me that DEC
management was furious when FOCAL displayed which kind of 8 it was running on.
Management wanted folks to think all 8's were totally compatible.
Charles designed P?S/8 to run in a 4K PDP-8 - making it feasible to run on a
basic 8/S (OS/8 requires a minimum of 8K). I hope it gets "released" someday :)
I'll miss Charles and his passion for P?S/8.

We wired in 8 engineering, DecComm11, and LCG together over the years.
