Re: VAX 780 on eBay
I had accounts on a MicroVAX 2 and a VAX 11/750. The microvax was faster for most compute jobs, but the 750 with 1/4 the memory handled more users mostly in text editors with the occasional compile or nroff/troff jobs. IIRC, the 750 had faster disks...

Re: VAX 780 on eBay
Yup. The 8600's (UMBC1 and 2) were connected to Bitnet, and I was a little Bitnaught until I found AI. It might have connected through the Gandalf network or something else, I'd have to check old printouts. Can I ask for a rough translation in to comparative VAX Units of Performance (VUPs)? I /think/ that the VAX 11/780 was 1 VUP. Kind of like MIPS, but I think they were going for throughput. The 780 may have had the same CPU speed as the Microvax II, but anytime you hit disk on the MV you were slugging down to the Q-Bus speed, going through a 4mb memory map window, and the RQDX3 wasn't either fast or very good IMO. The 780 would plow through the MASSBUS channel interfaces directly attached to memory (well, on a 780 everything went SBI) and RM03/RM80/RP07 drives were way faster than RD54's. And you could go to CI bus to talk to an HSC50 which could do more interesting stuff with RA81's and 82's.

Re: VAX 780 on eBay
The VAX-11/780 may be very slow, but it is still still quite a bit faster than my 11/730. That being said, the 11/730 captures the look and feel of that era of VAX in a much smaller volume and with a lot lower energy cost. Oh yes, the 730 is probably the neatest little "pocket Vax". Especially if you have the R80 drive as well as the RL02. The R80 did not use the Unibus, correct?

IOW they were combining existing modules to get the serial function, and adding the interface card to connect to the outside world.

Re: VAX 780 on eBay
The poles supplying my rural property just have one phase of 12kV on them, so even if SCE was willing to provide 3ø service to me, I bet it would be *expensive* to get the whole line upgraded to 3ø service all the way up to the last pole with all three phases present. I think that's probably within a mile or so, but that's still a bunch of poles to be upgraded. I use a rotary phase converter to feed my milling machine and lathe. If all three phases were on the pole already, I probably would have asked about getting 3ø service when I built on my property. But with just one phase on the poles, I didn't bother asking. They did just replace those overhead wires and some poles for fire prevention, and in the process they put in a whole great big pole-mounted switch that can be flipped from ground level just for my service disconnect, and another one for a neighbor's disconnect. It looks like they installed a regular 3ø disconnect switch, but only two of the wires are present and one switch pole is not connected. My service transitions from overhead to buried at that pole, and is buried for the last 100' or so to my ground-mounted transformer. Two of the poles they replaced were in the easement just on the other side of my property line. The contractors were happy with my cooperation in giving them access to my property so they could put trucks on both sides of the fence line. I also handed out 15 60mm ammo cans from my stash, since I like contractors on my property to be happy. So, they conveniently forgot to take the two old 45' poles they replaced with them at the end of the day, and I won't have to buy a new ham radio tower after all. ;) I am seriously lusting after that VAX-11/780 system on eBay, but I just don't have the available indoor space for it, or a big enough pile of cash to buy it and then spend enough to give it a good home. I'm glad that it's not in southern California, because if it was within an hour or two of driving I don't think I'd be able to resist the temptation. I do have my nice little 11/730 already. I'm eying the UNIBUS expansion bus from that seller to add to my 730, but I think should leave it available for the buyer of that 780. -- Mark J.

It's not uncommon for a farm to have 3-phase service--it's needed for things like hay dryers. For example, here's my rural electric co-op's rate sheet for 3-phase service: https://laneelectric.com/wp-content/uploads/GS-3-General-Service-Three-Phase-Eff-1-1-20.pdf By way of comparison, here's their single-phase general-service rate sheet: https://laneelectric.com/wp-content/uploads/GS-1-General-Service-Single-Phase-Eff-1-1-20.pdf The real sting is for 3-phase electric vehicle charging stations: https://laneelectric.com/wp-content/uploads/EV-1-Electric-Vehicle-Charging-Station-Eff-1-1-20.pdf In my rural location, 3-phase 11KV buried is available at a disconnect box at the street--single phase is buried along the driveway and terminates at a transformer on a pad in my front yard. Buried 240/120V single-phase 200A service then goes to the house. --Chuck

Yes, these "melted the socket, never tripped the breaker" failures are a result of crap receptacles. On basically all good brands of receptacles, the 15A and 20A have the same internal parts, anyway. It's my opinion that anything in a shop area, or really even the kitchen, ought to be spec-grade receptacles. They're not that expensive when you consider they'll last a lifetime. We always require Hubble spec-grade, and that's what I've installed at the house, too. > So ... over 10A continuous seems > quite possible if not expected with some installations. Indeed, you can have a continuous load up to 12A with no special NEC rules on a regular old branch circuit. Thanks, Jonathan

If other disks work when they are swapped in without making any other changes, it is probably not a termination issue. However, you still might want to double check that the DSSI bus is properly terminated at both ends. If the M7769 KFQSA is attached to a bulkhead connector panel, there are two versions, one with a single DSSI connector, and one with two DSSI connectors. If the bulkhead connector panel has a single DSSI connector, there should be SIP terminators installed on the M7769 KFQSA next to the DSSI connector on the M7769 KFQSA as one end of the DSSI bus. If the bulkhead connector panel has two DSSI connectors, the SIP terminators should be removed on the M7769 KFQSA next to the DSSI connector on the M7769 KFQSA, and there should be an external terminator on one of the two DSSI connectors on the bulkhead connector panel. If there is no bulkhead connector panel connected directly to the M7769 KFQSA, and instead it is connected to an internal DSSI bus cable inside the chassis, and the M7769 KFQSA is at the end of the internal DSSI bus cable, there should be SIP terminators installed on the M7769 KFQSA next to the DSSI connector on the M7769 KFQSA as one end of the DSSI bus. I would expect the other end of the internal DSSI bus cable to connect to a bulkhead connector panel, which should have an external terminator attached as the other end of the DSSI bus.
Re: What is a BC01-R

I found this: https://www.computerhistory.org/collections/catalog/102731577 but I think the number there is wrong; I'm not sure exactly which KL10 board is an 'MBOX Control 3' - it might be the M9537. > From:Ethan Dicks > Sounds like it was a generic cable that probably worked with several > devices. Yeah, the BC01-R was used with an M957/M970 header card (not sure what the difference between them is) in the DF11: https://gunkies.org/wiki/DF11_Communications_Line_Adapter Not sure where else. Noel
Re: What is a BC01-R
The original serial interface in the PDP-11 (later 11/20) was four cards in a specially-wired backplane slot. There was an M782(1?) interrupt controller, a data path module whose number I forget, and the interface. That card brought out the cable to the outside world. IOW they were combining existing modules to get the serial function, and adding the interface card to connect to the outside world. The later DL11 of course did it all on one module which fitted into an SPC slot and had a 40-pin Berg connector on the side facing the Unibus slots for the cable take-off. It's been along time since I took the factory training course on the PDP11/20, and I believe the ones I worked on in the lab at Maynard that already had a DL11 in them. cheers, Nigel Nigel Johnson, MSc., MIEEE, MCSE VE3ID/G4AJQ/VA3MCU Amateur Radio, the origin of the open-source concept!
