FTGH Old Issues of IEEE SigSoft Software Engineering Notes

by Rob Jarratt

I have a ton of these covering the period from around 2000-2005. I may have more. Are they of interest to anyone? They are in the UK. Would prefer local collection, I could post them in the UK if needed. They are going to be heavy, but if anyone *really* wants them then I might be prepared to ship them internationally. Obviously shipping will be for the recipient to pay, but the journals are free. Thanks Rob

Charles Simonyi on his flying experience with Howard

by Paul McJones

This is a very poor machine transcription of a Zoom conversation I had with Charles about 5 years ago. I went flying with him once a month. 00:15:04 Charles Simonyi Yeah the yeah this uh this kind of third hand plane and then flying with him and. 00:15:15 Charles Simonyi We were flying at night and we had a complete electrical failure. 00:15:21 Paul McJones Oh, really. 00:15:22 Charles Simonyi Yeah, in the San Jose airspace. 00:15:27 Charles Simonyi And dum dum. 00:15:31 Charles Simonyi There are actual procedures to come to. 00:15:37 Charles Simonyi Do. 00:15:40 Charles Simonyi You approach an airport with radio failure. 00:15:43 Charles Simonyi He was supposed to fly by the You know lookout. 00:15:47 Charles Simonyi Of course it was. 00:15:48 Charles Simonyi It was completely beautiful weather, you know, zillion visibility and and you were supposed to fly by the. 00:15:57 Charles Simonyi Uhm, he knew all the procedure. 00:16:00 Charles Simonyi We fly by the the control tower and then they guide you down with this thing called the light gun. 00:16:07 Charles Simonyi Which is a colored oh colored thing that actually you can see even in the movies. 00:16:13 Charles Simonyi You can see it kind of hanging from the from the ceiling. 00:16:16 Charles Simonyi There's this big flashlights, you know that you you can direct at planes and and and the weird thing is that that. 00:16:27 Charles Simonyi I was learning to fly at the time, so I'm doing a little bit of knowledge and and the when you clear to land, it's a it's steady green. 00:16:38 Charles Simonyi And flashing green means standby. 00:16:40 Charles Simonyi OK, wait for the client and and we saw this. 00:16:45 Charles Simonyi I saw flashing green. 00:16:47 Charles Simonyi And I said, wait, wait, it's we are not clear. 00:16:50 Charles Simonyi Yeah. 00:16:51 Charles Simonyi And and how it said no, no, no. 00:16:53 Charles Simonyi That's a steady light, except that they are not hitting us, right? 00:16:58 Charles Simonyi Oh Oh yeah, yeah. 00:16:58 Charles Simonyi Oh yeah. 00:16:58 Charles Simonyi 00:16:59 Charles Simonyi So I've just realized and and he said just look very close to the source and you can see a little bit of of the beam and see that it's steady. 00:17:10 Paul McJones OK. 00:17:10 Paul McJones OK. 00:17:11 Charles Simonyi And and I realized. 00:17:13 Charles Simonyi I mean, I still remember how. 00:17:15 Charles Simonyi You know, and then you would have to see this in a simulator or something. 00:17:19 Charles Simonyi Otherwise you know if I had been alone, I would have never landed because they they can't take you straight. 00:17:26 Paul McJones Yeah, yeah. 00:17:26 Charles Simonyi And I was thinking about this silly, silly distinction. 00:17:31 Charles Simonyi Because, operationally, it's it's very difficult to tell the difference, But anyway.

Apollo DSP80A/90 documentation?

by Kurt Nowak

Just a shot in the dark, but does anyone here happen to have a collection of Apollo documentation, specifically for the DSP80A/90? According to the Apollo documentation index they would be: Operating the DSP80A/DSP90 - number 004957 Unpacking and installing the DSP80A/DSP90 - number 004958 and Servicing the DSP80A/DSP90 - number 005806. Unsurprisingly, between my collection and Bitsavers, I cant seem to find anything on line anywhere. I'd be pleasantly surprised if i wasn't the owner of the only remaining DSP90. -Kurt

Re: Looking for MULTICS "screenshots"

by Craig Ruff

You can also run Multics in a simulator: https://dps8m.gitlab.io/dps8m It's been a while since I've been actively involved in that project, but it ran nicely.

Looking for MULTICS "screenshots"

by Steve Lewis

I realize MULTICS is from teletype era - so probably no old photographs showing MULTICS output in that form. But looks like MULTICS was actually in use for a couple decades, maybe some photo of a CRT with aspects of MULTICS presentable? Mostly trying to verify what the "list" command output looked like. But it should have some way to list processes also. -Steve

I have an opportunity to read some 3480 and related IBM format tapes, looking for someone in the Phila area who has the hardware to archive/retrieve the data from this format.
