Today, I picked up my trusty HP16C that's been with me through thick and
thin and noticed a black splotch extending across about half the
display. This is with the power off.
Is the LCD display failing? Can it be repaired? This thing has been a
a sidekick of my for a very long time and I'd hate to see it go.
I have been looking at the available software for the PDP8,
particularly languages. I see there was an ALGOL. The source is
archived on Bitsavers and dbit.
There is some information here:
Has anyone played with this before? Is there any additional
information on how to use it?
If anyone is interested, I documented a fairly easy way to prevent third
party SMTP relaying with MULTINET 4.1 on a VMS 5 MicroVAX.
I did cheat a little...I set up an email alias on my modern mail server to
forward messages to a single email address on the VAX. This was necessary
because otherwise I'd have to have added the mail host ID of every mail
server permitted to send email to users on the VAX. Also, I will have to
create an alias on the modern mail server for every VAX user who wanted to
I agree ultimately that MULTINET email is too limited, but for my purposes
I am satisfied. It's just for the learning experience.
EBay listing for a "Soviet Magnetic Ferrite Core Memory Board". It looks
like 20 something gigantic cores and a lot of diodes. I am guessing it is
some kind of ROM, but it doesn't look like a rope memory. And maybe the
cores are not cores at all, but some sort of inductor. I've not seen this
I am trying to bring some of my old PDP-11's back to life. Does
anyone have or know of a source for PROM Images? I need the
images for the M8189 (11/23+) and would also love to get the
images for my DECTalk.

I didn't have as much luck with Windows Photo Viewer. While it does
support multipage TIF, it seemed to hang after a few pages.
Irfanview is a pretty solid viewer/manipulator under Windows. I've been
using it to burst those TIFs into individual pages before making PDFs out
of them. I'll post a link to them when they're ready.
??????????????? For those interested in APE (the Altair Peripheral Emulator by Frank Barberis), I have recovered the site (with his permission) and Jay has agreed to host it on Classiccmp (thank you Jay!). It can be accessed at http://ape.classiccmp.org.
??????????????? No development has been done on it since 2014 when the original Comcast site went dark.
After sorting out the Model 4P (thanks to all who provided hints!) and scrubbing it up so it almost looks new again I turned attention to my Model 1 Level II which had been dead for at least the same amount of time as the Model 4. There?s some excellent troubleshooting tips for these machines out there and I quickly discovered a bad RAM chip, swap that for a NOS one and we?d be back in business if the video RAM wasn?t failing.
One of the 4 2102A chips is failing (MEM SIZE becomes OEO SIZE) and I?d like to double check this before I stump up the ukp4 required for a pair of NOS ones, can anyone think of a machine from back then that also used 2102A or 2102LPFC or NTE2102 video RAM?
