The history of ESXDOS: the firmware on the DivMMC EnJOY!

Two years ago I wrote an article about the complete history of ESXDOS.
It was meant to be published in Suc-Session or SPC  newsletter.
As it got being delayed, I posted the article at World of Spectrum, but simply never thought to post it here on ByteDelight.com.
So it’s about time 😉

A must read for all ZX Spectrum enthusiasts!

Connecting PC floppydrives to a Shugart (retrocomputer) disk interface

I often get questions about wiring PC floppydrives to a Shugart compatible floppy disk interface, which was the most used standard in the 80s.
So I decided to post the solution for this.

Underneath you will see two wiring diagrams:
1. Wiring PC floppydrives to a PC with a standard PC floppy cable: wires 10-16 are twisted before Drive A
2. Wiring  PC floppydrives to a retro computer with Shugart disk interface: wires 10-12 need to be twisted before Drive 0

So for using a PC floppydrive on a Shugart interface, the easiest solution (without having to solder on a PC drive) is to twist wires 10-12.

If like me you have a bunch of PC floppydrive cables you want to use for wiring PC floppydrives to a Shugart interface, it indeed implies that the twist on wires 10-16 must be removed and only wires 10-12 need to be twisted.
I have a stock of new 34 pin IDC floppy connectors for that, and use a vise to apply them to the cable.

Due to plugin incompatibilities I was forced to move to a new WordPress theme today.
At the same time I changed the colors and styling, and added the new ByteDelight logo!
Hope you like it!

Benophetinternet.nl no more..

I decided it was about time to say goodbye to the old Benophetinternet.nl.

The PHP weblog there had some major bugs, and the only reason to have kept it up until yesterday was because of some content.

I will migrate the content asap.
