View Full Version : PC/Server 500 and Media Sense Floppy Drives

April 19th, 2016, 09:27 AM

I have a PC Server 500 with a Media Sense drive which is somewhat intermittent. When I got it hardly worked at all. After cleaning it works sometimes, but still has problems reading diskettes written on my normal machines. I would therefore love to replace the drive with a GoTek or HxC Floppy Emulator but the drives in the PS/2 and PC Server machines have non-standard pin-outs. These are mentioned here but as the Media Sense and extended security pins:-


and scroll down a bit to the 34-Pin pin-outs. Has any one any information about how these are used. I can't find any info on the net about these pins.

There's actually quite a bit on the notes below the pinout charts. The best thing seems to be to leave the media sense/security NC.

Also, are you positive those switches are working? I swear I've come across a drive once that had a dead switch.

Floppy emulators are for cheapskates defeatists. ;)

I have one in the Yamaha EL90 organ with a dead switch, but I am pretty sure these work, but I will check. So I ha da diskette that worked and after a while it decided it couldn't read the autoecex.bat file. It was still booting DOS OK so I think its ether got low output heads, or , a cap has gone somewhere.
