FileServer II Board & 56k Bee

shane.crozier · 31-08-2026, 12:29 AM

Just a question on the FileServer II motherboard - sanity check please?

The Fileserver II board has connectors on it to match the 40 way (128k Bee) and 50 way (56k Bee ) Server machines

If I'm not mistaken the 56k Microbee drew power from the disk enclosure via the 50 way cable? - But pins 49/50 in the FileServer II board go to ground and D0 on the PIO? Were the 56k bee's modified differently to use the FileServer II boards and get their power from a different source?

Hi Shane.

Sorry for the delay in getting you the pictures of the floppy file server innards.
Here they are:

This one only has a 50Way connection on the FS motherboard, and it daisy-chains to the floppy disk controller board.

I'll check out the pinout of the version with the 40 & 50 way on it as time permits.

Thankyou! - Thats great - I had always imagined the power supply had to be bigger to power the Server boards (and winchester) in the server chassis.

The hard disk version layout is completely different, and includes a much bigger switched mode supply in the top part of the case.
