But that's putting and 8" drive on a 34 pin interface. That works
great. I want to go the other way around. 34 pin interface on an
50 pin 8" floppy controller.

I'll check this out.
How do you know if a termimation is suitable? Is connection all you have to worry about? I have an HP Ultra 320 drive, a 320/m compliant adapter (id jumpered to 2. Does a this need to be 0 for a single drive setup?), the cable with an ultra 320m terminator (" LVD + SE ACT NEG + HVD ISO " printed on it). Everything seems legit. I want to plug this into 2 different serverboards, an Intel SCB2, dual PIII, dual ultra 160/lvd channels, and an IBM xseries 350/Netfinity 6000 (8682 serverboard), quad PIII xeon slot 2 cpu's, similar scsi capability.
Does anybody have any contact information for Scott Lurndal? I'm
trying to get his V-Series emulator working (I downloaded it quite a
while ago), but it doesn't include any documentation and his wiki is
no longer available (and a lot of pages weren't archived). I can run
it and get to the coldstart screen but I'm not quite sure what to do
from there. Bitsavers doesn't have much documentation for Burroughs
45$ per plus honest shipping. These are new, bought them from Zon 7/2019. Never did anything with them.
I also have 2 power bricks, 1 new, 1 a little used (from an old Sony dvd burnwr). Free with purchase. Both supply 3 amps at least.
I suppose I could test these. I'll leave that up to tje buyer.
Yesterday, I was wondering, if there are any multiplatter disk pack production tools known to exist?
There are disk pack inspection and cleaning tools in the wild (also one on eBay for a ridiculously high price) and occasionally, I also saw unused and originally packed disk platters for sale, but these are, to my limited knowledge, worthless if the production and platter alignment tools are missing.
I remember vaguely somebody writing on this list years ago that some last systems were tossed by some company in California. But disk packs were also produced on the European continent and in for instance in Bulgaria(ISOT) for computer disk drives in the federal republic of Germany and the Soviet Union.
I was just wondering about this since it is getting more and more difficult to come across disk packs provided that spare unused platters arw available. The (9)877 for the CDC SMD 80MB drives 9762 and OEMs seemed to have been fairly wide-spread and these still show up from time to time for offer. But the 300MB packs for the CDC 9766 are rare now. Older drives are close to unobtainium. I never came across a five-platter pack for my CDC 854 drive and i have never seen packs for my MMD 844 or my CDC BC3xx disk drive for 200MB disk packs.
The question will rise what I wanna do with these. I have a working 9762 drive and some day, I would like to try to restore the other ones I have. For the SMD drives, I have spare heads and alignment tools and a disk pack cleaner. I don't intend to run them for hours because I don't have a clean room environment that is appropriate to the specs of these drives. I just love these pieces of storage technology and it would be great to at least have one pack for the drives that are missing one.
Any thoughts from the disk experts would be greatly appreciated :)
Not sure if my reply made it to the list. Yahoo seems to indicate it didn't -
When they prove idiots will be far less prone to hit me, I'll be for that. I'll still choose to drive myself though.
If you give someone else the keys, you may wind up going somewhere you don't want to. That'a what happens when you trade your autonomy for alleged security. The ****heads can do what they want. That's _their_ choice.
