Subject: PDP 8/L (was Re: Which PDP-8 is this? (ebay: 261232211533))
The 8/L arrived on Friday and I've finally had some time to take a few
pictures; I have a brief synopsis here:
http://rottedbits.blogspot.**com/2013/07/new-plaything-pdp-**8l.html<htt…
But the gist is:Aside from the rebranding, itappears to be a completely
standard (if minimal) 8/L setup -- 4KW of core, teletype interface and
that's it.It looks to be complete and in very good condition, though the
rack is ugly as sin(and weighs a ton). There's nothing else in the rack
aside from the 8/Litself. The teletype it came with is going to need a lot
of cleaning, but is solid and complete.
Also -- Thanks to all for the maskingtape removal recommendations; I'm
going to start with something minimal like WD-40 and move on to more
powerful options if need be.
Thanks!
Josh
The RICM revived a PDP-8/L that was in pretty rough shape. You can read
about the saga here:
http://www.ricomputermuseum.org/Home/equipment/pdp-8-l/pdp-8-l_blog Hopefully
you won't need to repair/replace as many modules.
I made a high-speed paper tape reader emulator from an Emcraft Linux
SmartFusion Evaluation Kit <http://www.emcraft.com/index.php/products/146>.
You can read about it here:
http://www.ricomputermuseum.org/Home/equipment/pdp-8-l/making-a-posibus-per…
It
connects to the Posibus and the 8/L thinks that it is the real thing even
though the read rate is more than 3500 CPS. It loads Focal in just a few
seconds. Your Teletype will take 13 minutes to load Focal.
