Yeah, tell those kids, which have now 1/2 TB on their phones ;-) I was musing about it, when I noticed few days ago, that a picture file of a decent camera this days is larger, than my RL02 was back then :(

John Nash
Hi all!
The book about John Nash ("Beautiful Mind'")[1] mentioned that he wrote
computer programs:
"Edward G. Nilges, a programmer who worked in Princeton University’s
computer center from 1987 to 1992, recalled that Nash “acted frightened and
silent” at first. In Nilges’s last year or two in Princeton, however, Nash
was asking him questions about the Internet and about programs he was
working on. Nilges was impressed: “Nash’s computer programs were
startlingly elegant.”"
Has anybody seen them?
Are they available somewhere for downloading?
Wondering...

Punched card file wanted
Now that I am finally getting my vintage computer accumulation in order, I need a punched card file cabinet. Does anyone know of one that might be available for purchase or trade? I am willing to pick up anywhere in the western US. In an ideal world, I would love to find one of the ones with a slanted front on each drawer that holds a single card for a label. I have an old wooden library catalog file cabinet (60 drawers) that I would be willing to trade, as well as some DEC Q-bus chassis. Any leads would be appreciated. Alan Frisbie
Re: Punched card file wanted
Library card not same size as purchased cards beware! We would love to find a nice wood library card catalog here in Arizona both a large and some desktop ones During the tossing of punchcards many of the metal card cabs were avail at 25 bucks each... wish we had bought more. Most people repurchased them as tool cabinets thecdrawers would hold lots if weight.Ed# Sent from the all new AOL app for Android On Sat, Aug 21, 2021 at 11:59 AM, Alan Frisbie via cctalk wrote: Now that I am finally getting my vintage computer accumulation in order, I need a punched card file cabinet.

ME11-L 3U fascia panel attachment Re: DEC ME11 Memory Expansion on eBay
I've been asked about the ME11 3U fascia panel bracket and how it attaches to the H-909 (slimline 11/05) cabinet, here is what it looks like. The metal originals are at front and my PET repops installed on the panel. There is not a lot of thread depth through the flanges but it seems to hold on well enough. http://www.surfacezero.com/g503/data/500/DEC_pn_211221_3U_fascia_to_H-909_slimline_cabinet_ME11-L_memory_expansion.png Steve

Noel Thanks Noel. I suppose if it was done it was a hack/not official system. Bill There were third party cassette systems, typically using some kind of digital cassette format, that you could hook up with a terminal. One was made by Sykes that I played with once upon a time: http://www.bitsavers.org/pdf/sykes/brochures/Sykes_3000_Cassete_Brochure.pdf But not UNIBUS - it was just a standard serial port thing, not tied to any particular computer system.

Further reading of the SPD seems to imply that Ultrix-11 was simply an evolutionary step from V7m to support more hardware - notably the 11.73. JRJ

Ultrix--11 2.0 did pull in some improvements from 2.9BSD, System III and System V, at least according to the SPD. Ultrix-11 3.0 pulled in networking from 2.10BSD (or 2.10BSD got it from Ultrix) at least based on source inspection. Warner JRJ >
