PIXAR's first computer used to make portions of the 3d short (Red's Dream) is now on Ebay (wife refuses to let me keep it and hang it on our wall).

twinax cards, linux, and hercules

by dgriffi＠cs.csubak.edu

A question for those of you who play with Hercules... Are twinax cards supported under Linux such that a 5250 terminal can be connected and work? -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

PDP-8 questions

by djg＠pdp8online.com

Not sure how separate classicmp pdp8 readers are from alt.sys.pdp8/pdp8-lovers readers so trying here also. Nothing new if you saw it previously. Does anyone have 4k BASIC or Spacewar? Poly BASIC, DECUS 8-195 seems to be 4k. I think Edusystem 10/15 BASIC also ran in 4k. I think there also was a 4k Poly Spacewar. I have this one which is 4k but it doesn't have gravity etc. / SPACE WAR / / INTERPLANETARY DEATH AND DESTRUCTION ON YOUR / LAB-8 / / EVAN SUITS My desktop straight 8 is missing the wood side panels so I want to make some. I took pictures and measurements of MARCH's but I can't remember if they were real wood veneer or imitation laminate. Does anybody know more or can look closely at their's? Online seems to think it was rosewood but doesn't say if it was real wood. One reply on pdp8-lovers said the desktop panels were imitation and another said the rackmount were real. Did current stright 8 owners do margin checks and if so what margins are reasonable to shoot for? The manual doesn't seem to clearly say. The last is the DF32 with the straight 8 has modified W103 device selectors. It seems that they were modified from pulse amp outputs to DC coupled level outputs. Has anyone seen this done before? http://www.pdp8online.com/dfds32/pics/w103-mod.shtml?small (next picture is schematic). I'm still working on getting the drive running so haven't seen if they work ok.

Complete "Amateur Computer Society" Newsletter Available Online

by lbickley＠bickleywest.com

The Amateur Computer Society (ACS) was founded by Stephen B. Gray in May, 1966. The ACS was for those who "are building or operating a homemade computer from their home". An interesting requirement was that the computer had to at least perform "automatic multiplication and division". In practice, membership was open to anyone who had a "serious" digital computer operating from their home. In my case that included a RPC-4000 ;-) Since I had been a member of the ACS, I had searched everywhere online for the complete set of ACS Newsletters - and found only isolated copies of individual newsletters. I did find that Stephen Gray had donated his original complete set to the Babbage Institute. Subsequently, I did a detailed search of the Computer History Museum's (CHM) archives via their Collections Department. I was excited to find that the CHM also had a complete set of the ACS Newsletter. I requested that they scan and make a PDF copy (including OCR) of same - and for a modest scanning fee they did so. It is now available to the world (free) via CHM's website: http://www.computerhistory.org/collections/accession/102654910 Go to the bottom of the page where there is a link to the PDF. For those who would like to know the earliest history of "home computers", I think you'll find it a fascinating read...

PDP-8 questions

by mtapley＠swri.edu

All, an humble suggestion: 1) Use cheap pine with a nice stain to make some "temporary" panels 2) plant a rosewood tree 3) maintain the machine for ~100 years 4) cut down your rosewood tree, make "real" panels out of it, and sell the excess rosewood to pay for electricity to run the machine. 5) meantime and most important, get back to classic-computer discussions on this list PS: Philip H., you are absolutely positively the man! I thought nothing could change the currently sagging signal/noise ratio on the list and my heart sank when I saw the 87k archive ... but then! / SPACE WAR / / INTERPLANETARY DEATH AND DESTRUCTION ON YOUR / LAB-8/E ....

I have the original of that version but its stripped down enough that its only sort of spacewar. I had heard there was a better 4k version and was hoping someone had it. I'm going with laminate, can we let the other thread die?

I have known about this pile for a few years now, and I have not been able to pin down who owns it, or if anything is being done to save it, past Computer History Museum's haul. At least they pulled some great stuff out. Most of it at this point looks like scrap, but I would like to see that CDC 841 disk system saved, even if it was a dog when new. Also the CDC tape and printer, and I suppose the comm unit. -- Will

PDP-8 C compiler

by v.slyngstad＠frontier.com

Rather than simply rekindle this annual discussion, I've decided to create a data point. So, you can read about (and download) an experimental PDP-8 C compiler at: http://www.so-much-stuff.com/pdp8/C/C.php I thought about delaying this notice until the first, but decided that since there really is a compiler of sorts there, that it would be more appropriate to do it now. Comments about the design decisions, improvements for the code, etc. are all welcome. Vince -- o< The ASCII Ribbon Campaign Against HTML Email!

VAXStation 4000/90, Reset Problems...

by holm＠freibergnet.de

Hi, at the Weekend I've got an Vaxstation 4000/90 with 64MB RAM and a 2,1GB Disc from a friend. Powered it up today and found a Problem. The Machine doesn't start properly if it is switched on, the LEDs are all stuck on (0xff). If I switch it off then and on again in a short time, it starts up properly, is doing the diagnostics and tries to boot an (defective?) NetBSD 1.1 that is loading the kernel but is getting then in a ?54 RETRY loop. Pressing the HALT Switch brings up the chevron... havn't tried to install something jet... Is that Error with the Reset/Startup known to someone here? I think it could be an dead capacitor in the PSU... Kind Regards, Holm -- Technik Service u.

TRS-80 Model II/16 hardware, and C cross-compilation

by eric＠brouhaha.com

After a lot of aggravation trying to get one working TRS-80 Model II, by cobbling together parts from three other machines, I've finally got one mostly working. I wanted to get my own programs running on it, cross-developed on a Linux system. Model II TRSDOS 2.0 and later have a built-in "receive" command that can receive Intel hex format from the serial port, which can then be saved to a disk file with the "dump" command. The serial port on my CPU card was broken. After swapping that card, which I intend to troubleshoot later, I found that the receive command won't work reliably above 2400 bps. (Maybe it would work at higher bit rates if the sending computer used a long inter-character delay.) I packaged up z80asm and z80dasm for Fedora Linux and Red Hat Enterprise Linux 6, and submitted them to the repositories. After verifying that I can get cross-assembled code to run, I set my sights on cross-compiling C code. I had to hack up crt0.s, putchar.s, and a linker script to work for the Model II TRSDOS environment (which is almost entirely unlike TRSDOS for the Model I/III/4), but it is finally working. The machine I've got working is actually a Model 16, but I don't yet have the 68K subsystem working. When I try to load TRSDOS16, it says that it has loaded, but immediately gets an exception at address 0. Xenix just hangs with no output. I've got a diagnostic disk that purports to be for the Model II and 16, but it has a lot of bad tracks, so I can't actually run the Model 16 diagnostics. Does anyone have a good copy of the Model 16 diagnostic disk? The disk drives in the Model 16 don't work. The spindle speed of drive 0 seems to be way off, and I'm not sure what's wrong with drive 1. Right now I'm using two other drives sitting outside the case, because I haven't figured out how to get the drives out of the Model 16. It appears that the machine has to be taken apart much further than I'd hoped in order to remove the drives. :-( Eric
