> From: William Degnan > 64K. That's 64KB, right? DEC used to talk of PDP-11 memory in words, back in the day, so it's never quite clear unless the 'B' or 'W' is specified. Anyway, 64KB out to be enough to run most things. I have't looked to see how big a system with just RL and DL drivers, and a minimum number of disk buffers (that's probably the easiest way to get the size down almost as far as it will go) is, but it's probably in the region of 30-35KB (20KB text, and 10-15 KB … [View More]

RL02 version of UNIX6?

> From: William Degnan > doesn't hurt to try I suppose Absolutely. > My fear is that it will not have enough RAM on top of whatever other > issues are present. Oooh, good point - I hadn't thought of that. I couldn't quickly find a 'minimum memory required' in the release notes for V6; the 'Unix Summary' says it needs "48K to 124K words". I think that might be a bit excessive; I seem to recall our -11/40 had, to start with, only 48KB. Anyway, try it, and let us … [View More]

RL02 version of UNIX6?

by jnc＠mercury.lcs.mit.edu

> From: William Degnan > Can one be made using simH to dump and set up for RL02 that can then be > ported as a RL02 disk image to actual RL02 drive? I see someone has already provided a pointer to someone who ha done this; I'm not sure if that system will boot on a hardware 11/40, or if it was built with m45.s, or some simlar issue. It would be pretty easy for anyone with a working V6 UNIX (either on hardware, or emulated) to do this, _iff_ they have a V6 RL driver. ('… [View More]

RL02 version of UNIX6?

by billdegnan＠gmail.com

I thought this question was answered recently but I can't find the answer. I have the RK disk version of UNIX6 for PDP 11/40 but I could not find an RL02 version. does this exist? Can one be made using simH to dump and set up for RL02 that can then be ported as a RL02 disk image to actual RL02 drive? I can get an image onto the drive, should the image exist. My PDP 11/40 is not compatible with Unix 7, but I would be happy with 5 or 7 if it'll run on a 64K system. Thanks Bill

RT-11 Basic source available

by jnc＠mercury.lcs.mit.edu

> Here: > http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/macro.tar > is a tar file with the whole works, along with the MACRO-11 source. BASIC is not ready yet, and won't be for a few days. The problem is that I can't get it to assemble into a working version, which I would like to do, before sending it out. I _think_ that what happened is we made some change in the toolchain, to support other things we were doing, and one of them 'broke' re-building BASIC - except that since … [View More]

Looking for Eyring PDOS for TMS-9900

by schubert＠microsys.de

Hi Camiel Vanderhoeven I nearly got all about PDOS and the TM990 system......however only on 8" floopy disks. I also have the complete documentation and a TM990/100M system with a DRAM and a Floppy-Controller board. best regards Walter Schubert -- MicroSys Electronics GmbH, M?hlweg 1, D-82054 Sauerlach Tel.: +49 8104 801-0, Fax: +49 8104 801-110 Sitz der Gesellschaft: Sauerlach, HRB M?nchen 48340, Ust.ID No: DE129296566 Gesch?ftsf?hrer: Dipl.-Ing.

Pac-Man (Alfred M. Szmidt)

by c.murray.mccullough＠gmail.com

As Alfred wrote: "How about some credit where credit is due, and not rewriting history willynilly. Toru Iwatani was the designer (not Nakamura) of Pac-Man, Shigeo Funaki did the code and Toshio Kai the music. Nakamura was simply the man behind the company, not the father of Pac-Man." I agree that his company created Pac-Man and in a corporatized world, then as is now, the owner(s) get the credit; i.e., Jobs of Apple, etc. And "rewriting history willynilly"; as an historian I definately try … [View More]

For Sale: Computer & Electronics Magazines: Byte, Creative Computing, Pop. Electronics, More...

by sellam.ismail＠gmail.com

I have several pallets of many boxes containing oodles of computer and electronics magazines that need to go. I'm not sure what all is exactly there but I'm going to be digging through them over the course of the next several months, so I'll probably just continue to update this thread with new material. There may well be lots of complete runs of certain magazines, and probably some frustrating discontinuities from boxes that didn't make it over. In any event, there is a lot of good stuff. … [View More]Here's what I have pulled so far: Popular Electronics, nearly a complete run from 1974 through 1984; also 1950s-1970s issues (uninventoried) Electronics Magazine, 3 bound volumes, April - December 1959 (see photo) - I plan to sell these in a complete set once I uncover all of them that I still have. It's possible I still have a complete run from the 1920s through the 1980s or so. PC World, Vol 1. #3 on upwards, incomplete (see photo). Dr. Dobbs, Volume 1, #2, photocopy of V1#1, many early issues from inception in mid-1970s thru... (again, this is just what I've pulled so far) Softalk, November 1982 onwards (incomplete, please see photos) Byte, January 1977 (Vol. 2, #1) through March 1983 (again, just what's been pulled so far, at one point I had maybe 5 complete runs of Byte) All photos can be seen here: http://s350.photobucket.com/user/Sel...ines/Batch%201 <http://s350.photobucket.com/user/Sellam_Abraham/library/Vintage%20Computer%…> I'll try to answer any questions as best I can. As a preliminary FAQ of sorts: 1. Yes, I will assemble bundles of magazines for different individuals upon request and ship them all at once. I will probably want some for of payment in advance though to secure the deal. 2. Yes, I will most likely ship via USPS media mail rate for the common stuff (this is how I received most of my magazines over the years) as this will be the cheapest method. For more valuable issues we can discuss more secure modes of shipping. 3. Yes, I have complete runs of a lot of magazines, but it will take time to dig them all out. I once had a complete run of nearly every (US) computer and electronics magazine ever published. What I now have is anywhere from a large to a substantial portion of that library. I don't know, this is the first time I'll be going through everything to see what's left. 4. These magazines have been stored in file boxes standing on their edges for years, packed very tightly. In not so tightly packed boxes some issues have curled up. In almost all cases, the magazines were kept in a cool, dry, dark environment so they will all be in about the condition I got them. In some cases I expect water damage. 5. I will charge more for the more sought after issues and peanuts for the long run schlock. My desire is to sell in bulk. The more you buy, the better your price. That should cover things for now. Happy shopping.
