Re: Quick journey to the basement
That's probably it. The drive is not stuck, so I'll put it on the MFM tester later this week and see what's up. Does the adapter board have its' own power supply? I'm guessing it's a Shugart SA1000 to MFM interface card. On the bottom side of it it says "Perq systems", that, the little stack of washers to offset it from the drive, and the numerous wire hacks on the board mark it as yet another product from the mighty Three Rivers company :-) God my shed is getting full C On 1/18/2021 4:44 PM, Mattis Lind wrote: Den mån 18 jan. 2021 kl 19:55 skrev Chris Zach via cctalk mailto:cctalk@classiccmp.org>>: Found more stuff. 4 Perq boards, the HP1000, a Perq mouse and "pad", a Sun4 keyboard with 15 pin plug, and another Perq2 keyboard.

DEC: securing 15V pwr monitor board in H765 supply
Hi all, I’m reassembling an H765 supply after cleaning and repairs. It has the "newer" style 15V and power monitoring board (the one with the edge finger connector, same as used in H7420 supplies.) The board slides into a slot in a sub-chassis that also houses the power control circuitry, which small chassis later slides into, and is secured to, the larger H7420 chassis. I cannot for the life of me figure out what, if anything, secures the power monitor board to the small chassis! There don’t appear to be any conveniently placed fixtures to which to screw down the board, and I haven’t been able to inform myself by pondering the various engineering diagrams, IPB’s, nor the pile of remaining fastening hardware... When I test-fit everything in the larger chassis, the unsecured board is held captive only by the grace of the surrounding wiring harness and by some small clearance issues with the large cap on the board. This doesn't seem satisfactory; as part of something like an 11/34 on tilt slides, it would seem to bang around a bit in there if left loose like that. Am I missing something? Puzzled... --FritzM.
Quick journey to the basement
Found more stuff. 4 Perq boards, the HP1000, a Perq mouse and "pad", a Sun4 keyboard with 15 pin plug, and another Perq2 keyboard. Also found a weird one, a MFM drive with an adapter board on the bottom. Is the below a MFM to Shugart interface? Pics are up on the Discord server right now along with the HP1000. C
