PDP-11 COBOL-11 or COBOL-81? (was Re: Anyone have DIBOL-11, CTS-300, or CTS-500?)

by spacewar＠gmail.com

DIBOL-11 seems quite rare these days. Is COBOL-11 or COBOL-81 any easier to find?

Couple of Xerox 6085 questions

by tmfdmike＠gmail.com

1. Anyone who has played with Xerox systems will have encountered the dreaded 0937 code at boot time; it means "I have been configured for network operations. I abjure the world and will wait until hell freezes over before continuing the boot - unless I get the time from a network time server!" This is inconvenient and frustrating at times. Netware IPX/SPX is basically Xerox XNS implemented pretty much unchanged; does anyone happen to know if a Netware server can provide network time server functions - and in a way that a Xerox workstation would grok? 2. I haven't powered up my 6085s in a long time - at least 5 years; maybe 10 for some of them. The results have been most disappointing. They won't even *start* POST - and/or they give a rolling screen with no sync - and/or a blank screen - and/or they pass POST but won't boot with an 0151 error. I've tracked these down in most cases to flaky IOB boards. These boards hold the system PROMs. Anyone else seen similar issues? Could it be bit rot in the PROMs? Is that a known thing with 6085s? Thanks Mike

Looking for printers: Epson Stylus Pro 9000, Epson 9500, Lexmark 7000 Z11

by sieler＠allegro.com

Hi, I'm looking for some old inkjet printers for a legal partner: Epson Stylus Pro 9000 Epson 9500 Lexmark 7000 Z11 They're from about 1998 or 1999. They probably have fixed nozzles across the page, no moving head. Assuming they're of the correct vintage / acceptable, a bounty will be paid. thanks! Stan Sieler sieler at allegro.com Cupertino, CA

Apple Lisa 2/10 for sale

by ramdyne＠gmx.net

Hi, We at Hack42 have an Apple Lisa 2/10 for sale at http://www.ebay.nl/itm/121893065311. When we powered it up for the last time 18 months ago, it appeared to be working (no nasty smells etc) but we didn't test it very much. What has happened since is anybody's guess. Note: shipping to the US is *really* expensive, but within Europe is only slightly less painful (with packaging it'll reach 25kg easily). Pickup is an option. -- Andreas

IBM (Sony) PowerDisplay 20

by stefan.skoglund＠agj.net

Howdy. I connected one of theese (i have two) to an PC last night. Blemishes: the text is blurry wrong color tones (a little bit red) so how much can i do with the display picture setting buttons ? I'm thinking about connecting one of them to a Sun 10 (but i do have a bunch of RS 6000 PPC machines.)

Tool to convert between Motorola FFP and IEEE754 float formats?

by classiccmp＠philpem.me.uk

Hi, Does anyone know of a tool which can convert between Motorola's FFP (Fast Floating Point) float format and IEEE754? I'm trying to reverse-engineer some ancient 68k code which uses the FFP library, but a load of the floating point constants have been hard-coded as hex constants, which is making things hard to interpret... I've tried to convert the 68k assembler in FFPIEEE.SA to C, but I must have missed something because it just isn't working... Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

Stuck bits on 11/73 Clearpoint 4MB memory - how to repair?

by jnc＠mercury.lcs.mit.edu

> From: Jacob Ritorto > I struggled for hours with inadequate eyesight, tools and materials, > but I think I got this mod done! That was quick! I had an 11/23 on my workbench that had had that backplane mod, so I took it apart to take a picture, to help you, but I guess that's OBE... :-) > the machine's stuck in self-test at error 47, Memory CSR error. It's not clear that that's really a hardware problem. DEC makes assumptions about how many memory CSRs there will be, etc, and some third-party board 'fail' when they don't meet those expectations. I have a Clearpoint QED1 (I think that's the one, didn't check) that does that. > What I assume is the parity light on the third party "Clearpoint QRAM-2 > SPB-1 88B" lights during self test. I've found no documentation for this > sucker as yet.. I have a PDF of the "User Information Manual" for the Clearpoint Q-RAM 88B. (Oh, I see, later message says you found it.) No prints, alas. Anyone have any we can scan and put online? > I'll have to find my rl02 controller and build the system up some more > so I can run xxdp and find out what exactly died. I would tend to use diagnostics as 'help', not my main tool in diagnosing faults. This is particular true as really bad issues can prevent the diagnostics from loading/running, so if you get skilled at fault analysis without depending on them, you're better situated to deal with the failures that prevent using them. > Can anyone offer hints as to how to identify which component is broken > and how to go about repairing this? As other have said, lacking the prints, pulling chips (if they are socketed) ought to enable you to work out which chips goes where. (I'v worked out the chip layout for a number of un-documented memory cards this way.) I don't know about your 88B, but the one I have photos of, and my other Clearpoint cards, the chips are in sockets. With luck yours will be too... If not, ask if someone has one with sockets (alas, I don't have an 88B), who can do the mapping for you. Important: once you have worked it out, pass it along! I'm trying to upload all the data I've collected about cards for which no documentation is available to the Computer History wiki. > It's the only memory board in this machine, so I guess the problem > might actually be a bus or processor board, right? Could be. I have an KDJ11-B which has stuck bits, and that's the CPU board, so yours could be to. > I have no other q-bus memory to test with, so can't do swapping / > process of elimination to be sure. It's definitely worth having another small QBUS memory card to use in fault isolation when debugging. M8044's are readily available on eBay for about $20. They are only Q18, so not usable in the same machine as Q22 memory, but they are useful for debugging. I would definitely invest in one. (If you luck out and get a bad one, send it to me, and I'll swap it for a known good, tested, one. I've fixed a whole bunch of them, got to the point where the last one I did for someone I didn't even have to pull out my 'scope! I could tell from the symptoms exactly which chip to replace! :-) > From: Jay Jaeger > Well clearly it is only affecting certain address bits - or the > diagnostic would not run at all Well, like I said, I do have a KDJ11-B which will run the on-board startup diagnostic, but which has a bit stuck hard on the QBUS interface! So those machines seem to be pretty resilient. Although as you point out, if he can load and run the diagnostic, it's probably not the CPU. > note that it is starting at 010000000, so that points to the memory Yup. If some locations work, and others don't, it's almost certainly the memory. And since he's only dealing with a single memory card, it's probably not the bus drivers/receivers on that card, either. One can use ODT on the KDJ11-B to poke around, and find the envelope of the problem. (See comments above about not relying on diagnostics! They are better for saying something's busted, than for accurately telling what _is_ broken.) With that, and a chip->memory map, it should be fairly easy to replace the offending chips. Noel
