Wish I could find some of the card images I used to feed it -- give it a thousand line program and at some indeterminate time later it would simply say "Syntax error" and that was that. No hints what the error(s) was / were or where it / they were... Hamish |

The loss of radar will not cause the ATC facility to hit an aircraft or terrain. But it could cause an aircraft to hit an ATC facility. Probably why you guys are moving all those tracons off the fields and into safe locations in the middle of nowhere. LOL! One of the standard jokes around the Center here is that no matter how bad you screw up, at least the wreckage won't hit the building... Chip, say again the coordinates of your Center facility. :-) Matt |

Personally, I like the washing-machine-like RP06. I love the seek tests that looks like someone put it on the "spin" cycle with a couple of wet towels off-center. Did the RP06 have removable media? I can't remember. I do remember lugging around the RL02 disks though! Matt |

Yup. Big stacks with about 10 platters (I think). I still have a
read/write head from one. We 4 or 5 of them. Then got an RP07 "Winchester" drive (non-removable). Someone once told me that the term "winchester" came from IBM, where their non-removable drive was the 3030. Any truth to that? (The RP07 was even more energetic during seek tests.) Matthew S.

I actually still have the "boot PROM" from an old PDP-11 (not sure
which model) -- it's just a standard Unibus board with 16 diodes and a bunch of resistors on it. You cut the diode leads for a zero, left 'em alone (or soldered them back) for a one. It's larger than your PowerBook... I am quite sure it had 256 diodes (I modified one to boot not only from 8" floppy, but from papertape and disk as well). This was on a PDP 1140. I remember that machine fondly: I was writing up my graduate paper and had been typing for more than 2 1/2 hours (without saving! the foolishness of youth...) when the lights went out, and the machine with them. Bother. I put the machine in halt mode (nice toggle switches on the front...) and went to restore power. When I had power back, I took out the source code for the operating system (RT11) and the editor. I assumed the editor had been at the "waiting for input" point and found out which PC location it was. I entered this location with the toggle switches, put the machine in run mode and saved my work. The joys of core memory! Later I worked with a PDP model 1122 1/2. |
