I assume you have access to a VMS box that can read the relevant media. If so you can create a container disk using LDDRIVER (or one of the many other equivalent freeware utilities). Then use VMSINSTAL to extract the savesets (all the savesets) to [000000] on this disk. You may or may not have to manually intervene since VMSINSTAL depends on saveset naming conventions that may not have been applied in the V4 days. Assuming you fill in the blanks above, you will end up with a bunch of valid savesets in [000000]. You can now use STABACKIT to make the LD disk bootable into Standalone BACKUP. (If you feel like it, you can put a complete OpenVMS system on there ... you might as well since your kits *must* reside in [0,0] to work!!). Now disconnect and dismount the LD disk and burn the contianer file to CD as a block-by-block binary (CDR-Win and Gear can both do this, Easy CD cannot AFAIK and Nero and Clone CD I have not used enough to have a worthwhile opinion). You can, assuming you are set up to do this, burn directly from OpenVMS with CDRECORD. >Is this possible?

If, however, SIMH won't accept an ODS-2 CDROM, you'll have to do a binary FTP of the savesets to a PC and burn >from there (although how SIMH can cope with the result, I do not know) or pick up the OpenVMS mkisofs (I have a pointer somewhere ...) and use that directly.

SURVEY: Powering big iron in your home.

by healyzh＠aracnet.com

> I wanted to conduct some survey of the common practices (which > may or may not be good practices) to powering your very own mini > and maxi big iron in your home. I think this topic may be Well, the biggest I've got in our apartment is my PDP-11/73, and a couple of PDP-8's. They're small enough they plug into a normal wall socket. Oh, there is also the VAX 3500, but I've not even plugged it in to see if it works. Hmmm, then there is the really big 'computer', does a 4 slot Neo Geo Arcade machine count as 'Big Iron' :^) Or is that 'Big Wood' :^) However, in my folks garage I've got my PDP-11/44 with a pair of RL02's. Since the system is supposed to have a 15A feed, my Dad built a 'extension' cable that plugs into one of the sockets next to their washer & dryer (not sure why they've a spare socket). It's been a few years since he built it, however, I remember that he built it useing parts that were spec'd at 15+ amps. The only problem with this is you can't do laundry while the PDP-11 is running. Now my question is, what are you doing about cooling? I know the /44 will get my folks garage up to a comfortable temp fairly quickly in the winter, and it can only be run in the morning in the summer. Zane

Diagnosing a non-working Mac Performa 476?

by mythtech＠mac.com

>When I power up the system, with monitor attached, the internal cooling >fan spins up, the hard drive spins up (and sounds normal), and the >machine chimes what I seem to recall as being the regular start up sound >for this era of Mac. However, the display remains dark.

I've played with the >brightness and contrast controls without any success. Your start up bong should be a single smooth tone. If it is a "melody" of any kind, it is not a startup bong, but rather chimes of doom. The melody will tell you what may be the problem. The first thing is to check the PRAM battery. Many Macs will not start properly with a dead battery. If it is dead, Radio Shack stocks all 3 kinds used in Macs (but ironically, standard PC CMOS batteries are special order). I don't recall if the Performa 47x used the square 4.5 volt, or the 1/2 AA 3.6 volt. I think it might be the 1/2 AA, but either way, it will be pretty obvious when looking at the logic board. Also, press the CUDA button on the logic board (again, I don't recall off the top of my head if the 47x has one, but I think it does). This will be a small red button on the logic board. I seem to recall on the 47x it was either near the ports on the back of the board, or near the front by the floppy and HD connections. But again, it might not be there at all. The CUDA button will do a deep hardware reset, this will clear any screwed up hardware settings it might have (and is usually recommended to do after changing PRAM batteries, or adding or removing cards). Finally, if none of that works, disconnect the HD and floppy. You should get at the very least when no drives are connected, a grey screen with a disk with flashing question mark. If THAT doesn't work... do you have access to another Mac? Can you make a known good bootable floppy disk? (you can download a 7.5 disk tools image >from Apple's web site). Build a disk, and put it in the drive (reconnected drive that is), and try to boot from it. If your system is working, but the monitor is dead, you will head the Mac doing a bunch of accessing of the floppy drive as it boots (They will boot fine with no monitor attached). But with all this, I suspect the problem will be a bad PRAM battery, or a need to press the CUDA button. -chris <http://www.mythtech.net>

[CCTECH] Motorola S-record converter source for new project

by RCini＠congressfinancial.com

Hello, all: I'm starting a new project...an emulator for the Altair 680b. So, I'm collecting random bits and pieces of code that I might need to implement it. What I'm looking for now is source code to read/write Motorola S-records. There is a nice source code file that exists for reading/writing Intel HEX files but I haven't been able to find a similar one for S-records. Does anyone have such a thing?

[OT:] "VGA loop cable" pinout for Hauppauge WinTV Prism

by Arno_1983＠gmx.de

Hello guys, this item is almost certainly not to be considered "classic" yet, but it also isn't "leading edge" any more, is it? I'm asking here because even with hours of googling, I wasn't able to find a pinout for the missing cable and I figured that somebody on the list might have the thing and be willing to meter it out for me. The installation procedure tells you to disconnect the monitor >from your graphics card, connect it to the TV card and plug the loop cable into the graphics and the TV card. It is the exterior cable that I didn't get (DE15HD -> Mini-DIN-7); I have the interior "feature connector" ribbon cable. If you could tell me which pins to connect, I should be able to solder a replacement cable.

KC/Topeka prowling with Mr. Rigdon

by ghldbrd＠ccp.com

Returned to my last gold mine in Topeka; Joe and I found some nice stuff. With his sharp eyes he found more Amiga memory & SCSI cards for me. He went home with some S100 memory cards, and a B&H (black) Apple II. I came home with another C64, two 1541 drives, another Ozzie I with modem, and miscellaneous Apple II cards and documentation. Surplus Exchange(in the west Bottoms) had the goodies cordoned off; I believe they are throwing out the vintage stuff and rearranging the salable PC stuff. Had a find time killing the day. My thanks to Joe and his sharp eyes; what he found really made my day. Gary Hildebrand St. Joseph, MO

Replacement tube for IBM 026 Printing Card Punch

by dwightk.elvey＠amd.com

Hi Look at the wiring. If it looks similar to what is on the other 25L6's, you should be OK. You should check the grid voltages on all of these tubes. Incorrect bias can cause excess plate disapation. This will shorten the tube life to minute/hours.

Possibly OT: IBM 4224-01 printer question

by msspcva＠yahoo.com

Hi: I think the subject of this message isn't quite 10 years old yet, thus the "OT". I've got two IBM 4224-01 printers I recently acquired >from a company going out of business. Both units exhibit the same problem/symptom - when I power them up, the LED display will flash, the fan just starts to spin up, and then - nothing. It seems to die off completely. Since both are doing this I thought I'd ask the list to see if there's something else I need. Both of these have Twinax interfaces, which I'm not familiar with at all - I've tried connecting a T-connector to one of them to see if it's some sort of termination problem, but see no difference in behavior. My purpose in getting these is to resell them, so I'd like to know if they work or not so I can price them. Any help appreciated! -- Frank ===== = M O N T V A L E S O F T W A R E S E R V I C E S P.

[CCTECH] Unknown terminator identification

by DAW＠yalepress3.unipress.yale.edu

Hello gents. Considering all of the old DEC equipment, and other old hardware that is, and has been, in use here in my building, I'm fairly positive this terminator falls in the 10-year rule... I have here a terminator of some sort. It's a male 37 pin (DE37?), the hood is black plastic, no identifying marks on it. Only " CONTACT 11.2964 075 " on the metal shroud that surrounds the pins. Inside is one of those orange circuit sheets, with an blue rectangle chip on it. The chip is marked... 14-3- 221/331 *B 8418 ... there is 106027 on the end of the sheet, with REV. B on the side. The logo on the sheet looks like a stylized MB. Here's what the pinout is... Chip - Connector 1 - 21 2 - 20 3 4 - 16 5 - 14 6 - 13 7 - 1 8 - 29 9 - 22 10 - 23 11 - 24 12 - 25 13 - 26 14 - 27 Any ideas what it is, and what its for?

re-keying an RS/6000 lock?

by fernande＠internet1.net

I just picked up an RS/6000 7012-320H this weekend from Sean Caron. It seems complete, but I haven't tried to power it up yet. It's currently keyless. How hard would it be to re-key it to use the key from my 7013-530? I've never tried such a thing. Anybody done it, or tried it? Chad Fernandez Michigan, USA
