In this video, I try out some Qume 8 inch floppy drives that I bought on eBay. I interface them to a WD37C65 controller on my Z80 CP/M computer and I format the disks and read/write some files to them. For more retrocomputing projects, see www.smbaker.com/

Wow, Haven't even seen an 8" floppy for about 25 years. Well done. Thanks for the videos.

Some 8" floppy drives used a long spiral cam shaft on the stepper motor. I had some like that years ago.

Same sort of discs that where used on the OLIVETTI M3030 and it turns out that a high power mains three phase motor driving both drives via a three pulley drive shaft that of which one pulley connects to the motor spindle which drives both floppy drives. if you are wondering what computer I am talking about well it was in the shape of a desk with the electronics inside a cage inside back of the desk and it also had the floppy drive on the left side of the desk and printer on the right it also had a B&W monitor.

Well done... I spent a few months trying to get an 8" floppy hooked up to a PC/XT (it was that long ago) and didn't really get there.

I love that LED display. Do they make larger ones? Would be sweet to have an 80 column 25 line display I that style. Super retro but also smaller than a CRT. I have a real Digital Equipment Corp VT420 with amber display that would also work nicely with this computer. I gotta get my own CP/M machine!!!

I have a few 8" disks that were for the IBM System 36 computer.

3 minutes for 40 tracks? I'm curious - did you try a different sector interleave to reduce track to track time ? these parameters are readily available in the CBIOS of CP/M (or perhaps you did not use an OS just direct programming). In any event, I envy you - I cut my teeth on CP/M 1.4 and an IMSAI S-100 that had a Xitan SMB Z80 and a dual 8" (Shugart 800's) floppy drives interfaced to Intel's DIO S-100 floppy board and now wish I'd not been so quick to "upgrade"....what memories....nice video...
