Several years ago, Hans Pufal of ACONIT was one of the people working on restoring a PDP-9 to working condition. In the course of the restoration, they found many DECtapes of PDP-9 and PDP-15 software, which he put up on some personal pages on the museum's web site. The pages are long gone, and the Internet WayBack Machine has only partial remains. In particular, the images of ADSS15 source DECtapes 2, 3, 7, 8, and 14 are missing, along with the .zip files for ADSS15 and DOS-15. Does anyone on the list have copies of these (especially the DECtape images)? Feel free to contact me privately if you like.

DEC RQZX1 and KDJ11-E boot problem?

No problem, and the questions so far have not been simple or obvious, so I think it's actually good questions, which also others might benifit from.

The basic formatting of a disk is the same for all. In fact, with SCSI, you just send a command to the disk itself, asking it to format itself. So there can't be any differences on that level. If the RQZX1 is doing some tricks, it will have to be that it hides some blocks for it's own use, and put data there that it "needs". Those will be normal disk blocks, and another controller will see them as just simple data blocks in that case. However, I should stress that I do not know if the RQZX1 really does this or not. I know that the CMD controllers do not. I've written disks on a Unix machine, and moved them over to a PDP-11 without problems. But I have not tried this with the RQZX1, so I don't know if anything is different with that controller. > I have a plan B - if I can find a way to convert the .TAP file and > then "dd" onto a DDS tape I can try booting that by attaching a TZL09 > to the RQZX1.

Hum? I thought it could. However, you might need to move jumpers around to allow for that. This also made me realize that maybe you have your controller configured in a specific way that explains a thing or two for me. The RQZX1 can be configured as disk-tape or disk-disk. In the disk-disk case, one of the disks will use SCSI units 0-3, while the other will use units 4-6. That would totally explain why your SCSI id 4 maps to MSCP lun 0. You're on the "second" disk controller. And that also explains why you cannot use any tapes. As I said before, I don't have a RQZX1 manual anywhere near, so I can't help with the configuration here, but I suspect you might want to look more at this. > Does anyone know what interface the RQZX1 has for tape? it looks like > it could accept a TK70 cable. Just SCSI as far as I know. The only other connection is for a floppy, unless I remember wrong. Johnny

OT: TV/Electronics help needed....

by woyciesjes＠sbcglobal.net

Apologies first, but I know there are some good A/V guys here... Please reply to me _off-list_, since this isn't ClassicCMP, and I'm only subscribed to the daily digest. I got my self a nice (older) RCA DVD player, model RC5220P; as seen here: http://www.amazon.com/RCA-RC5220P-DVD-Player/dp/B00000J05A Now, on the back, there are 2 phono jack connectors (one yellow, one white); which are labeled RF output. The manual says you need to use an RF adapter, part number CRF800. Here's my question: in usual A/V tradition, a yellow phono connector is composite video, and white (not paired with a red) would be a line level mono audio. Is that the case here? I ask, because I would like to use it with a VCR that only has mono phono connectors. And yes, searching the web was most unhelpful.... I'm tempted to just hook it up to my Sony A/V receiver, but don't want to fry anything..... -- --- Dave Woyciesjes --- ICQ# 905818 --- AIM - woyciesjes --- CompTIA A+ Certified IT Tech - http://certification.comptia.org/ --- HDI Certified Support Center Analyst - http://www.ThinkHDI.com/ Registered Linux user number 464583 "From there to here, From here to there, Funny things are everywhere." --- Dr. Seuss -- --- Dave Woyciesjes --- ICQ# 905818 --- AIM - woyciesjes --- CompTIA A+ Certified IT Tech - http://certification.comptia.org/ --- HDI Certified Support Center Analyst - http://www.ThinkHDI.com/ Registered Linux user number 464583 "From there to here, From here to there, Funny things are everywhere." --- Dr. Seuss

pdp10 rack free for pickup in northern Germany

by hachti＠hachti.de

Hi folks, there's a DEC rack from a pdp10 computer sitting in a basement around here (Kiel). It's the pdp10 pendant of the common H960 rack i.e. it has the same size but everything else is slightly different. Comes empty and in fair condition. No faceplate. But both grey side panels. There's one DC distribution panel at the lower left side. If anybody is interested, please contact me! If nobody likes to pick up the rack, it will go to scrap sometime next week. Kind regards, Philipp P.S.: Sorry, I currently have no pictures.

I know I've seen ads for these in the past. Can anyone inform as to those models that were available here or in the great white north (er Canada).

Commodore C 900 documentation and software required ...

by bernd＠kopriva.de

Hi, a short time ago, i got hold of a C 900 (bare machine only, no keyboard/monitor), that i want to get working again ... I have already searched the Web for specs of keyboard and monitor but without success. The machine has an AT-type keyboard plug, but it's not clear (at least for me), if a normal IBM compatible keyboard will work. As i have the workstation version, the display resolution should be 1024*800 which seems to be a bit uncommon, so i'm not sure, which monitor could work ... Can anyone provide some documentation, that would help to find a working keyboard/monitor ? Getting the software for the machine would be very helpful too ! ... Thanks a lot Bernd

IBM S/370 retrieved

by mcguire＠neurotica.com

I've just taken possession of a small IBM System/370 mainframe, and I thought I'd share the joy. This system has been sitting in North Carolina waiting for me for about six months; I've only now been able to arrange for transport due to financial restrictions. I've got 450 pictures and nearly a gigabyte of video to sort through, but here's a quick series of shots, including one or two with yours truly striking a pose: http://www.neurotica.com/misc/s370/ The system is a member of the 9370 family. It consists of a 9375 processor, five 9335-B01 disk drives (824MB/ea), two 9335-A01 controllers, and a 3430 tape drive. Everything was shrink-wrapped and sealed with IBM anti-tamper stickers. All the cabling is present; it's all coiled up in the back of the processor cabinet. I also received a mountain of documentation which I've not yet gone through. Everything is absolutely pristine save for some tape residue. I broke the seals and unwrapped the system personally, with camera rolling and heart pounding. Thanks to my friend George Adkins for the Herculean effort of loading it onto a truck in North Carolina and bringing it down here, and my friends James Sharp and Pat Sherrill for assisting with the unload. If I can get it running, I'd like to run VM/370 and/or MVS on it. It originally ran VSE/SP. On that note...does anyone have an appropriate console terminal for this system that might be available? I believe that'd be a 3215, or perhaps an early (C.U.T. protocol I think) 3270. I am so happy about this I can hardly contain myself. =) -Dave -- Dave McGuire Port Charlotte, FL

OS/8 editors, was Re: Programing PDP-8 assembler - details

by djg＠pdp8online.com

Can I talk you into making >them available? > I have a copy of vista here http://www.pdp8online.com/pdp8cgi/os8_html?act=dir;fn=images/os8/dewar-edit… In a search I found this http://vandermark.ch/pdp8/local/Sources/read_dir.php?f=Other/new-22-vista-2… It appears to be the vista editor source. The actual vista source seems to be in the empty at the end if its complete. I haven't tried to build it. Has modules for a couple different terminals.

Making Amiga Disks

by alhartman＠yahoo.com

Just to let all the folks on the list know... There's a program just like the Disk Transfer Utility for Apple ]['s called "Amiga Explorer". It's sold by Cloanto, who makes "Amiga Forever". Being an owner of that, I have the program. All I need to do is find one of my Null Modem Cables to attach a PC to the Amiga 500 to transfer disk images. It will even install the program needed on the Amiga end over the serial connection. So, once I get the Amiga 500 sorted out (the unit came badly packaged, showed up in pieces and isn't working...), I'll be able to transfer OS disk images to it. Anyone have advice on which version of Kickstart ROMS and OS is the best/most useful on an A500? Is there a driver to use a ZIP Drive as mass storage? Or use an old Adaptec Parallel Port SCSI adapter to run a Disk Drive? Al
