Yes, but the irony if us replying on-list isn't lost.

The last one that I received was October 20th.
oddly there were times you could dial into a broken dec 10 connect
and end up connected to someone elses session.... Ed#

I used to use the DECSYSTEM-20 from a Teletype (until they got replaced by
VDUs). That is why I really wanted a nice Model 33 ASR, which I now have.
sometimes connect it up to SIMH running TOPS-20 to relive the happiest part
of my school days.

In case anyone is interested, I have finally cobbled together a web page
that documents the construction of the Popular Electronics Cyclops camera
that I exhibited at the 2016 VCF East. It also documents my work to produce
a Cromemco S-100 Cyclops that I hope to exhibit at the 2018 VCF East. The
page is here:
The Cromemco S-100 Cyclops starts down the page a bit.
This email has been checked for viruses by Avast antivirus software.
the vertical heat sinks for the TO220 with this design are fairly common, I
saw them many times on various boards.
However, as they are simply aluminum parts, you can clean them for sure.
After removing the screw, you could try simply with an hard brush.
If badly corroded, remove the bubbles of oxide with a thin sanding paper,
then you could restore the opaque aspect submerging for few seconds in
caustic sodium solution. Be aware to protect eyes and skin!
Replace the RIFA X2 capacitor!!!!
Anybody familiar with the internals of these disks? I have one here
which seems to have the positioner stuck at track zero. I'm not sure
whether it's likely to be just a bit sticky and in need of some
assistance or whether there is some sort of latch involved, and I am a
bit reluctant to just pull the lid off the chamber to find out.
IT RUNS MEMORY RESIDENT LOADED FROM PAPER TAPE?

Hi DEC Enthusiast's,
If I were to have to decide on just one model DEC PDP system to run in a DEC
Emulator, which one would be the most useful, versatile and has the most
software available for it?
I have only ever used a real PDP-8/e system way back in high school so I'm
not up to par on any other model of DEC PDP system and I only know BASIC on
the PDP-8/e so not much there either.
I hear a lot about the PDP-11. I found out that there were 16 major PDP
models at one time so I'm not too sure which one to pick.
I built Oscar Vermeulen's PiDP-8/I which I'm waiting on 1 part for. Other
than that project which is in a holding pattern at the moment, I have no
other PDP anything running in any form.
Back in the day when Bill Gates and company 1st started out, I had always
wondered how they developed their very 1st software program - Altair Basic.
I was pleasantly surprised one day when I saw a B/W photo of a young Bill
Gates bending over the operator at what looked like a very small computer.
Maybe it was just a terminal. I don't remember. I understand they did
software development on a DEC PDP of some sort.
Finding this out regenerated my interest in the DEC PDP line of computers.
I have many projects in the works already so I decided to setup a software
emulation of just one of the DEC PDP models. I have heard a lot about the
PDP-11 which if the information I read is correct was 16-bits. My PiDP-8/I
is 12 bits. I understand the PDP 10 was 36-bits and the PDP-15 was 18-bit.
The PDP-11 is the model I hear the most about.
I also have some experience on some version of a VAX when I was in the Air
Force so I'm thinking of getting a VAX emulation going at some point too.
So if I'm going to do this, what suggestions, pointers, experiences,
etcetera do you guys have for me. I am very interested in the DEC PDP
equipment though next to no experience so I have no basis to make a
decision. This is a serious request so I would definitely like to hear what
you all have to say. If you have read this far, thank you. Take care my
