Josh & Pete: Thank you for the identification. Don't think that the unidentified quad-boards constitute a SMD controller. I guess the SMD controller was in the second chassis and went wherever the HDD went. Strange that the PS didn't go with it. I can feel a bit better for not having recognized the PS :-}.
Rick: The UDA50 is cabled up the rear of the rack to a connector-plate near the top of the rear-rails. No photo of the plate present, but the cabling is clear on the side-photo of the rack. So presumably there was a second rack in the original configuration ... probably also housing a vertical-mount 9" tape drive. -----Original Message----- From: cctalk <cctalk-boun...@classiccmp.org> On Behalf Of Pete Turnbull via cctalk Sent: Friday, December 3, 2021 9:30 AM To: General Discussion: On-Topic and Off-Topic Posts <cctalk@classiccmp.org> Subject: Re: Unrecognized DEC Power Supply in PDP-11/44 Configuration On 02/12/2021 16:37, Josh Dersch via cctalk wrote: > On Thu, Dec 2, 2021 at 6:29 AM pbirkel--- via cctalk > <cctalk@classiccmp.org> > wrote: > >> Does anyone recognize the (presumably) DEC power supply on the front >> half of the rack-bottom in the 11/44 listing at: > It's not a DEC power supply, it's a Fujitsu power supply, likely for > an > M2284 SMD drive. Probably went in the empty slot you mention below. Yep. Looks identical to the Fujitsu PSU in my 11/40 rack, and the rails are the same as my Fujitsu rails. -- Pete Pete Turnbull
