Most (all?) current boards no longer have a floppy connector. My most 
recent motherboard, a mini-atx, doesn't even have an IDE connector.

I still have my Z-80A system with two Tandon half-height 8" single sided 
drives. I haven't attempted to power it up in 25 years. I also have my 
original CP/M 80 disc and my original TurboPascal version 1.0 for Z-80 
on an eight inch disc with the manual. I doubt any of the discs are 

Single sided, single density eight inch discs hold 243 KILO-bytes. If I 
remember correctly, a standard disc had 77 tracks with 26 sectors of 128 
bytes per sector per track. The original 5.25" single sided disc had a 
capacity of 160K. I don't remember the layout.
