eBay VAX-11/780 has a few minutes left...

by fraveydank＠gmail.com

Someone please tell me the VAX-11/780 mentioned a week ago is going to be bid on, because if it goes to the scrap heap, I think I might just cry (because I don't have the space or money for it). http://r.ebay.com/eaHRC6 - Dave

simh VAX 11/780 tech support

by jon＠jonworld.com

Folks, I'm trying to get BSD 4.2 running on a VAX 11/780/simh setup. This is working well under OpenBSD. I have the 4.2 BSD VM up and running. I'm having difficulty with networking. I'm using the pre-compiled simh package from OpenBSD which has networking support and running it as root to make sure it has access to the network interface. simh seems to be attaching to the network interface; I'm getting status messages about how Eth is attached, etc. simh is 3.9. No network devices to show up under the OS, though. Given that 4.2 BSD has TCP, is made for VAX, etc, the default kernel should automagically detect the network "card" presented by the emulator, right? For some reason it isn't. I also tried the other xu type=deluna (I think that's it, I don't remember from memory.) Here is my boot.ini set cpu 128m set rq0 ra81 att rq0 rq.dsk set rq1 dis set rq2 dis set rq3 dis set xu enabled set xu type=deuna att xu0 em0 set rp dis set lpt dis set rl dis set tq dis set tu dis set tti 7b set tto 7b load -o boot42 0 d r10 9 d r11 0 run 2 Is it an ordering/address space thing? Do I have to throw the "xu" stuff further down in the file? Thanks! -- -Jon Jonathan Katz, Indianapolis, IN.

Current verrsion of SimH for a PDP11 which runs under Windows 98SE in a DOS Box

by jhfinedp3k＠compsys.to

I never thought that I would be asking for this again, but after 10 years (my current version of SimH is V2.9-11 from 2002) I think it is reasonable to check out some new code on the current version of SimH. While I still run SimH from a Dos Box under Windows 98SE, I also run under Windows XP. I use SimH so rarely that I never bothered to generate a variant to run a PDP-11 under Windows 98SE for myself. But I have some new code which needs to be tested under as many different emulators and hardware as possible. The new code runs correctly under the newest E11 and that old 2002 SimH. I want to be sure that the code also runs correctly under the newest SimH and DEC hardware. So, can anyone please help with a link to a PDP-11 variant of SimH that runs in a Dos Box or just e-mail me a copy? While I am running these tests, does anyone use any other emulators than E11 or SimH? Charon used to be available, but does not seem to be around any more. Jerome Fine

What a service like Google would have looked like in the 1960?

IBM would almost have certainly limited options to a 1050-series device for that application. Given the 16-bit P-counter, this would have had to have been a 360/30; the 360/20 addressing scheme allowed for no more than 15 bit addresses and I think the actual limitation was 16K. I don't know about the 360/25, however--I never saw one. --Chuck

40 years of PDP-11 hoarding has to end... (England)

by dm561＠torfree.net

----- Original Message ----- Date: Thu, 13 Dec 2012 11:12:04 -0500 From: David Riley <fraveydank at gmail.com> I'd be willing to bet that Pittsburgh is not a small city relative to most in Manitoba. It's actually not even that small relative to Philadelphia or Baltimore, neither of which I'd consider small. That said, Manitoba is an AWFULLY big province. You could probably find someone with similar interests, though they might be a fair distance away. ----- Reply: As a matter of fact Pittsburg's population is twice that of the entire province of Manitoba! It may indeed be a big province (almost the size of Texas), but its total population of around 1,250,000 scattered throughout that big province is half of Metropolitan Pittsburg's 2,500,000...

Fwd: Retrochallenge 2013 Winter Warmup - Registration Now Open

by mark＠wickensonline.co.uk

Entry now Open for Retrochallenge 2013WW! Entry is now open for the 2013 Winter Warmup Competition to be run between January 1st and January 31st. Please email /wgoodf at googlemail dot com/with your name (or handle) a brief synopsis of your project and a URL for your blog. About Retrochallenge In a nutshell, the RetroChallenge is a loosely disorganised gathering of RetroComputing enthusiasts who collectively do stuff with old computers for a month. The event is very much open to interpretation? individuals set there own challenges, which can range from programming to multimedia work; hardware restoration to exploring legacy networking? or just plain dicking around. It really doesn?t matter what you do, just so long as you do it. While the RetroChallenge has its competitive side, it?s not really a contest? it?s more like global thermonuclear war ? everyone can play, but nobody really wins. Come on? give it a go! Competition Rules 1. RetroChallenge commences 1st January 2013 and runs until 31st January 2013. 2. In order to qualify, computer systems must by approximately 10 years old (or older!) however exceptions will always be made for exotica! 3. Gaming consoles and PDAs qualify if they were made in the previous century. 4. Where appropriate, replica hardware and emulators may be used. 5. Entrants are responsible for adequately documenting their projects and submitting occasional updates during the contest. 6. Projects may encompass any aspect of retro-computing that tickles the fancy of the individual entrant. 7. Winners will be carefully selected and thoughtfully chosen prizes presented (hopefully before the next challenge commences). 8. Have fun! http://www.retrochallenge.net

It's realllly slow (about 25% slower than the 11/750) but physically small and only has 5 memory slots for 1MB boards. Using TU58 as the console boot medium made booting even slower, but if you copied all the files off of your tape (with EXCHANGE) and built a new tape (also with EXCHANGE), you could order the files properly and since the TU58 microprocessor appeared to cache the directory track(s), loading was then sequential and *substantially* faster. The 11/730 wasn't so bad if you used it like a single-user workstation. -ethan
