Questions about Austron 5000 Loran C receiver

Does anybody have any info on the 2100C receiver. I have one that somebody
gave away, mistaking the listing for a 2100F.
Speaking of 2100's:
If anybody already have, or wouldn't mind reading out the EPROMS of
their 2100's, I would appreciate it.
My aim is to disassemble them and find out more about how these
receivers actually work.

Never attribute to malice what can adequately be explained by incompetence.
Will do. Give me a few days.

Hi Andy,
Thanks for the link.
Wow, I've never seen one of those before. Looks like 60's design with those
nixie tubes.
Hope you manage to get it going.

Hi again: Thanks for all of the replies so far.
I took a few photos of the unit for Mr. Kimberely. They are a front view, a
rear view and one of the label on the side. Not the greatest shots, but you
can view them here:

As you'll see, interfacing it to something doesn't appear to be simple.
However, I'll look into the emulator links. I appreciate them.
I do not have the full set- only the receiver part. Every online image I
have found looks like it's sitting on the PDP-8

Ok wasn't as hard to-do as I imagined, CPU boards come out the front without
removing the receivers from the bottom of the stack. They are 2732A a set of
three f0-f2, I have a Rev G and Rev 107 I don't know why they are different
name scheme both receivers are 2100F and look the same.

Hmm, interesting. Youre r.G and r.107 look a lot like each other,
and nothing much like my r.107

Geez, I have read and I don't think it is possible to replicate the CALOC
PDP-8/E software nor it is useful to use the Austron 5000 Loran receiver,
my understanding is that it was used to control and steer the system. It
seems they were in use until the year 2000! Maybe that using MATLAB it is
possible to exploit the Austron 5000 functionality nowadays, provided that,
someway, the 12bit samples from the Austron are transferred to the PC.
Anyway to start with, at least the receiver connectors pinout is
mandatory...

There are PDP8 emulators out there. Not to mention actual
microcontrollers that implement the PDP8 instruction set (aside from the
no-doubt out of production Intersil part).
And a fair number of FPGA implementations in your choice of language.
While it might not be as scenic as that nice plastic see through housing
with all those discrete DTL circuit cards in the original straight 8. I
used a 8/i way back in the early 70s and I was bummed that it was just a
single box in the rack.
Hi
Ahhh... The days of toggling the boot loader in with the front panel switches. So much fin.

I still have a PDP/8 with 4k core memory out in the garage. (a jillion RTL
cards in it). It was free to e then, broken, ...I had to find t\all the bad
transistors....
During college, ..I would sit in the floor with that thing and toggle in
small programs in machine language to count up and down, seemingly
impressing everyone with the binary lights dancing on the front panel.
...this all makes me want to pull it out and 'toggle' some more, again....

Hi
Time to get out the paper tape for 4K Focal and do some code...
