I've been thinking over the idea of connecting a 5.25 floppy drive to laptops, Thinkpads in particular. There are not so many options, which are external LPT or SCSI drives. But these are rare, expensive and I'm not sure they even exist.
So when I found out that there are slim 5.25 drives, like Canon MD-5501, TEAC FD-155GF of Epson SD-700 (which has slim body and a normal face plate) I thought that it would be possibe to install it into DOCK I instead of the slim SCSI CD drive. As for the physical dimentions, I'm almost sure it will fit. But the problem is to connect it to the system.
There is a 26 pin FDD controller on the MB of the dock, but it's a weird Hirose connector (HIF6B-026PA-1.27DS(71) to be precise), I have no pinout, and not sure the built in controller supports random drives. Also there is no way to set up a 5.25 drive in BIOS.
So my idea is to install an additional FDD controller that has own BIOS. As I read online there are controllers that support 4 FDDs and have onboard BIOS.
My question is what do you actually think about this? Is this a workable idea? Any suggestions on controller model?
Or maybe there are better ideas?
Any feedback is higly appreciated.

Oh, that's right. Unfortunately it does not seem to be a possible solution.fultontech wrote: ↑Mon Dec 14, 2020 11:55 amThere actually was an IBM 5.25 drive option that connected to the original dock using the external mainframe drive. It required the full length microchannel controller card in the slot. I ran across part numbers in someone's copy of the IBM PC Support data. The problem today would be finding a working, late 1980's 1.2MB upgrade drive that installed in the caddy. Most on eBay are the original 360KB drive.
Here are the p/ns from the manual:
T21 2647 T22 2647 1@ 1GHz SXGA+ 4 more; T23 2647 1@ 1.2GHz SXGA+ 3 more
T30 2366-88U 2GHz; 2366-83U 1.8G; 5@ 2366-LU0/66U; 2367-KU6 FUBARd
T41 T42 T43
T61 8897 2.4GHz SXGA+; 8898 2.4Ghz; 6463 2@ WSXGA+; 7658 2.5GHz; T61p; 6 more T61s
As for the controller - will try those newly made 8 bit ISA FDC controllers for XT machines with own BIOS. I'm looking forward to try how it will interact with TP.
