Subject: my pdp11/53 and pdp11/73
Hi,
Ever since I first saw them at the University where I worked in the late
80's
and early 90's, I wished I had one to experiment
with myself, but they
have
neither gotten cheap nor plentiful over the years. My
first computers ran
CP/M, SCO Unix, then SunOS on a SPARC-4/110.
So my 11/53 just arrived, and my 11/73 is on it's way, both in BA23
chassis.
Inventory of the 11/53 is:
KDJ11-D/S CPU
Dataram 4093 with 2MB RAM
RQDX3 controller
The power supply checks good, the cabinet is remarkably clean inside, and
I
get the countdown from the console port, then it tries
to boot from a TEAC
drive I had that matched the smashed one that came with the system. No
network card in this one, but the 11/73 will have a Delqa with it.
I'm pleased there are still so many links that haven't expired to
documentation, and nice web pages and youtube videos by others like
myself who have resurrected these systems.
I wish I hadn't thrown out all my MFM drives, years ago when I moved,
since
I don't think I can do much more until the 11/73
with a hard drive shows
up,
and that machine will have the Delqa card too.
I have some questions that I have either not been able to answer, or for
which I've found confusing answers.
- What are the rules for cards & slots in a BA23?
You can find online manuals about the BA23 here:
