help needed: problem with UNIBUS access on my PDP-11/70

Ok, many tips to check on this weekend. > Did you catch your washing machine;-) Just curious what the washing > machine has to do with checking your power supply voltage?

As Andreas says, when the washing machine runs, turning on any big PDP-11 blows the fuse. I have to reset all clock radios and the clock on the microwave oven. I definitely will check the DCLO and ACLO signals! I will use the scope also to check the +5V lines for any ripple.

To clear things on the question from Tony, when I push the START button the PAUSE led goes on immediately. I will not get that far that I can try to access to the DL11-W again. I will swap the M9302 at the end of the backplane (it is there, I just forgot to mention it) with an M930. All slots that need a grant card according to the Field Maintenance Print Set (FMPS) have one installed. The FMPS shows G727 flip chips for one slot of the 4 slots per MASSBUS interface that not installed, and all UNIBUS slots at the end of the backplane. I had the same experience as Ethan did. When I removed the TU80 interface from my 11/34C the system hung. I inserted a double grant card G7273 and all was fine again. Have I nice weekend, - Henk.

Fw: This weks finds for the museum

Ectomic Group ASPS Process Controller?

by foo＠siconic.com

Some guy contacted me wanting information about a series of equipment that controlled a "huge circular saw used for cutting huge quantities of wood". I'm looking for any information on the following: ASPS Process Controller ASPS Executive Controller ASPS Schedule Controller ASPS Monitor Controller The labels he found indicate it was made by Ectomic Group out of Arlington, Texas. Along with these large racks are two Teletype ASR-33's. Apparently this is from the 1970s. My guess is that this is a process controller that may well be based on some mini-computer like a DEC or other mini-computer of the day. The guy who relayed this information to me is basically computer illiterate, so he probably can't be of any help to identify anything beyond what he already gave me. He's located near St. Louis in Pacific, Missouri. He is tasked by the owner of the equipment with trying to sell it to get the highest amount possible for it. I told him at best, if anything, to expect someone to come and take it away at their cost. He also has a Wang computer that is the "size of a dishwasher" that is separate from the lot above. Merle? (Sorry, no model number.) If someone thinks these things are worth saving, let me know and I'll put you in touch. My guess is that the guy will try to extract some cash from you for it, but that's up for any potential rescuer to deal with. An offer of scrap value should do it.

OS/2 for PowerPC

by bernd＠kopriva.de

Hi, does anyone have that OS ? I've got a Motorola PowerStack, which i want to use with something more exotic than Linux or AIX .... ... OS/2 PPC should run, but i've never seen it ... Is there any other (exotic) OS available for that machine ? Thanks Bernd Bernd Kopriva Phone: ++49-7195-179452 Weilerstr. 24 E-Mail: bernd(a)kopriva.de D-71397 Leutenbach Germany

Conquest???

by Antonio.Carlini＠riverstonenet.com

I have a vague recollection of a game that might fit the bill - assuming it's sources still bore traces of having travelled through RSX at some stage. I'll have to see if I still have my old tapes kicking around the attic - it's about time I migrated them all to CD anyway. Antonio

Conquest???

by Antonio.Carlini＠riverstonenet.com

There was a game called Empire which had a VMS incarnation (start with one city, build armies, conquer the world, ASCII only). If that's what you are looking for, I'll see if I can dig it out.

Well, obviously the H744 isn't the problem, but it looks like you're one short. I have a spare, and I'll be seeing Ed in 2/3 weeks.

Time for a reality check now! The machine runs! DCLO and ACLO is not the problem. What is the problem is a total hang when trying to access the DL11. The question is if he can access the I/O page at all. I haven't heard any confirmation if it is possible to read from the bootstrap code locations. They are also in the I/O page, and thus is a very interesting test. PAUSE goes on when you start boot, but that don't tell us enough. The boot roms don't access the console, so we atleast know that the DL11 isn't the only problem. I suspect you have problems accessing the I/O page in general. But can you access the MMU registers, and other processor registers at the I/O page? And still, NPR might be the problem. If I remember correctly, a broken NPR might show up just like this. The same goes for the BG lines. Remove and reinsert the grant cards, check the I/O page more. You have access to memory, and can run programs, so let's skip the stuff that we know is working correctly.

Amiga 1000

by doc＠mdrconsult.com

Well, I held off for a year and a half, but when the A1000 hit $5 I couldn't help it. I bought it. Now all I need is a keyboard, joystick, and a clue, none of which were available at Goodwill. I do have a display, thanks to Bill Bradford. Will a 1541 or 1571 external floppy be a good addition? Which? ISTR that there's no reasonable hope of genning up a boot floppy on a PC or Mac, right? So I need to find someone to dupe disks to get started? Or <shudder> pay for them? Anybody have a pile of spare keyboards & mice? Doc
