Pre-release for the IBM PS/1 and PS/2 teardown video!
Added 2023-04-28 03:55:21 +0000 UTCWell this was a tough one, but fortunately I've got it finished before the weekend! Tearing down and testing the IBM PS/1 and PS/2 from the Franklin eWaste haul. Also decided to throw my darling PS/1 from my personal collection in the mix, because we had to borrow its monitor. Experimenting with some different camera angles in this video, so please let me know what you think! Thanks!

I do recall my 50Z having a backplane-style PCB. I'm not sure if the 30 ever had one as I only ever watched my dad disassemble it. Somehow I still don't own a GoTek. I should probably rectify that situation soon!

2023-04-28 16:33:13 +0000 UTCIn photos I've seen for the PS/2 interface, it appeared to me IBM used a PCB with an edge connector socket that receives the drive and interfaces with the motherboard. The PS/2 floppy drives seem to have a reputation for mechanical failures and capacitor issues too such that adapters for standard 3.5 floppy drives to that card-edge connector where made. (which admittedly doesn't help you in this case) I'll try and keep digging. Out of curiosity, do you have a GoTek on hand? They are very helpful for testing.

2023-04-28 16:22:42 +0000 UTCI might have to create a custom adapter. These cables seem impossible to find.

2023-04-28 13:07:12 +0000 UTCYeah I might need to go the XT-IDE route and 3D print a drive sled adapter.

2023-04-28 12:01:29 +0000 UTCEverything I have read about this model says to not even attempt to use the on-board hard drive interface. The drives weren't standard in any way, and the few that were made have long since failed. This is not an MFM/RLL interface. Your best bet would be XT-IDE, or if you really want SCSI, probably an ISA SCSI card.

2023-04-28 05:10:45 +0000 UTCI have one of these. The floppy cable/connector is specific to this PS/2 model; not used on other PS/2 models. They chose to use a single cable to send both power and data over the same cable. The data and power are standard though, so technically it would be possible to create an adapter to split out and re-arrange the pins back to a standard floppy interface.
