- Yep - the 8/I was my favorite, even at the expense of a slightly slower
- instruction time than the other machines in the lab. (Someone had added
- pots to the system clocks - a couple times a year during PM they'd
- tune the clock speed up as fast as the processor could handle it, then back
- off a few percent.) Aside from the rocker switches, my favorite part
- was the full register display - made debugging that much easier.
-
- RIM loader? We never had to do that... Just toggle in the network
- bootstrap, then 7600, Load Address, Go.
-
- All the PDP-8's I worked with were on a star network, with a pair
- ("Network Central") at the hub running the disks. Years before anyone
- thought up the term "file server".
-
- And, of course, the first thing that the OS did when it booted was to
- load the bootstrap into all available extended memory - if you only had
- a minor crash, you could just select an alternate segment and boot
- from there.
-
- Question: Was the network part of a standard OS, or was it just
- something developed at Northwestern? (The hardware looked homemade.
- As I recall, it was a 40kword/sec network - add to that CRT terminals,
- instead of the usual ASR's - pretty nifty. Not to mention the system
- with extra hardware for doing 4-channel realtime music synthesis, or
- the one with the vectorscope display that did "Asteroids" years before
- the game hit the arcades...)
-
- My nomination for PDP-8.godhood: Mr. Rich Karhuse. Formerly head of
- the Northwestern CS Research Lab; last I heard, working for Bell Labs.
- I heard stories from several reliable sources that, upon discovering
- a bug in the network central systems, he would halt the machines from
- the front panel, toggle in the changes in memory and AC/L, then continue.
- (And then, of course, document the fix... :') From talking with him
- on numerous occaisions, I have no reason to doubt the stories.
- Rich, if you're out there, many thanks. The environment you provided
- was one of the single greatest influences on my professional skills.
-
- These kids today just don't know what they're missing.
