Hi, I've been trying to build some of the old dungeon (zork) source files I've manage to find... I've bee using SIMH, and it's TS-11 v4 distro I found some Fortran stuff here: http://www.headcrashers.org/comp/rx01/ When I run SIMH, this is what I get for "show cpu" CPU, 11/73, NOCIS, idle disabled, autoconfiguration enabled, 256KB This is my ini file: set cpu 256k att rk0 rtv4_rk.dsk att rk1 dungeon1.dsk att rk2 dungeon2.dsk att rk3 asc.dsk I've figured out how to install the compiler from some PDF's and the test program will build. However when attempting to link dungeon I'm getting this error: ------8<------8<------8<------8< ?LINK-W-Undefined globals: CVTTIM GTIM $OVRH ------8<------8<------8<------8<------8< I cut out the references for CVTTIM & GTIM from the source, but the OVRH is not found... People tell me it's an overlay manager but I cannot find any mention of this thing anywhere as far as where to find it, build it link with it or anything..... I can provide more detail if needed but I'd really appreciate any pointers on this... TIA Jason.

We used the task builder as a linker, and then a utility, again written by some student, to convert the image to Intel Hex. I think the PROM burner was controlled by the PDP as well. I'm sure you could do the same for the 6502. /Jonas

Hi, Has anybody heard of a 6502 assembler running under RSX-11M? And is there any documentation for it? Thanks, Ed -- Certified : VCP 3.x, SCSI 3.x SCSA S10, SCNA S10

sector numbering on floppy and hard drives?

by lynchaj＠yahoo.com

Hi! Why does sector numbering start with physical Sector 1 on floppy and hard disks? Cylinders and Heads begin at 0 but sectors start at 1. What happened to Sector 0? I am referring to physical address not LBA. I am just wondering. Thanks and have a nice day! Andrew Lynch

Fixing a 386SX laptop

by thypope＠gmail.com

Hello everyone, My oldest machine is a Goldstar Gold Note 386SX 20 MHz with 2 MB of RAM. I'd like to do many things with it, but no matter what I try to do, at some point the screen starts going dark and then bright and then dark again...varying in brightness until you can't focus on what you are doing anymore. It's a grayscale LCD. Apparently no dead pixels at all. I've been told by someone who fixes motherboards and other things for a living that it's not the screen but something else. However, the man claims he has no time to look into the machine and find the problem. If anyone has any idea of what could be wrong, wether it is possible to fix it and hopefully how, I'm all ears. I will even send it to whoever can fix it and pay for the repairs, like I intended to do with this local gentleman. I'm very curious to at least hear what's wrong.

I have a > VAXstation II/RC that ran MicroVMS. To clarify about VMS / MicroVMS versions I've looked into some VMS V4.x tapes and found out the following: Version Type Date written MicroVAX support V4.0 Full 23-SEP-1984 NO V4.1 Update <missing> ?? V4.2 Full 12-JUL-1985 NO V4.3 Update 9-JAN-1986 VMS043.A-COMMON FILES / VMS043.B-VMS ONLY / Saveset VMS043.C-UVMS ONLY V4.4 Full 30-MAR-1986 YES (integral part of all Savesets) V4.5 Update 26-SEP-1986 same as with V4.3 (individual Savesets) V4.6 Full 15-JUN-1987 same as with V4.4 (integral part of all Savesets) V4.7 Update 29-OCT-1987 same as with V4.3 (individual Savesets) That seems to me a rather good proof that MicroVMS versions are (at least from V4.3 onwards) functionally equal (to the extend possible on MicroVAXen) to the corresponding VMS versions. Distribution tapes were identical, whereas the RX50 floppy sets most probably were not (as to save space/floppies). I'm still looking for the following versions: - MicroVMS V1.0 ( = MicroVMS V4.0 ???) - MicroVMS V4.0 - MicroVMS V4.1 - MicroVMS V4.2 - VMS V4.1 - VMS V4.2 MUP (Mandatory Update) - VMS 4.3A - VMS 4.5A - VMS 4.5B - VMS 4.5C - VMS 4.6A - VMS 4.6B - VMS 4.6C - VMS 4.7A Can anybody help ??? All other versions are available to anyone who wants them. Regards Ulli P.S. My MicroVAX I runs MicroVMS V4.4, my two MicroVAX IIs run a VMS V4.6 LAVC together with two VAXstations 2000 Who else has got MicroVAX Is or at least parts to build one??? I'm currently scanning EK-KD32A-OM-002 MicroVAX I Owner's Manual for me & bitsavers.org.

Reviving old environments (was Re: Free VAX/Alpha hardware)

Do you have a Qbus COMBOARD? ;-) I think one list member ever has piped up that they found a COMBOARD in a rescued system - we sold a few thousand Unibus "COMBOARD I" (HASP/3780) boards over 12 years or so, a much smaller number of Unibus "COMBOARD II" (SNA), and an even smaller number of Qbus COMBOARDs (HASP/3780/SNA), and by comparison, a microscopic number of VAXBI COMBOARDs (HASP/3780). If anyone still cared about setting up sync links between VAXen and IBMs, I'd have more motivation to work on these sorts of projects, but since I never have gotten the DWBUA working on my 8200 after it moved to my house, I don't really have a ready-to-use environment for testing our old Unibus products (of which I still have a couple tubs). Qbus is easy, as is VAXBI. It was a great product for the 1980s, but I don't really hear any buzz about sync serial comms anymore. -ethan

Old VMS distros (was Re: Free VAX/Alpha hardware)

That sounds right from what I remember. After that point, it became a memory/disk space issue, not an architectural issue. I don't recall when uVAX-I support was dropped, but I don't think VMS 6.0 is supported on an RD54 (though it _can_ be mostly wedged in there). > I'm still looking for the following versions: > > - MicroVMS V1.0 ( = MicroVMS V4.0 ???)

I have many of the earlier ones of those, on original media, though I can't guarantee what will read and verify from 20-year-old media. I will certainly give it an attempt. We had an 11/750 on software support from their initial release in 1983 through 1993, MicroVAXen from their release in 1984 through 1993, and an 11/730 that probably used the same media as the 11/750, IIRC. Some of our MicroVAX stuff was on RX50; some on TK50. We ran (u)VMS and Ultrix. I was able to save about 80%-90% of the distro media when the company closed (some of the earlier stuff may have been recycled since TU58s and RX50s were considered "expensive" and "why would we ever want that old stuff anyway). I do have a pile of DEC distro floppies for the Pro series that turned into backup and transfer floppies, so are decorative, but not functional now. :-/ Since I recently went through the exercise of creating a Compaq utilities disk for my Portable II, I'm in better shape to archive RX50s. I'll have to dig out my TSZ07 to image install tapes. I will not get to any of this before Thanksgiving, so please don't ask, but feel free to rattle my cage (offlist, please) if it's January and I haven't made a peep. If you need it sooner, I can't imagine that I'm the only person in the world who still has 15-25-year-old backup media - someone must have much of this stuff spun up somewhere (though I can undertstand not wanting to make it available all the time to random passers-by). -ethan
