Another divIDE repair today.
Very simple, with the device connected I got this

As Ive found with all of the divIDE boards that Ive repaired the EEPROM was blank. A re-flash sorted this problem out.

There is apparently a reason why this keeps happening and has got something to do with the way the Spectrum regulates power at startup.

Dieter sent me some dumps from his Wonderboy bootleg board.
All the PAL’s were unprotected and he converted them to GAL’s and has tested tham all.

Thanks to him for these

Looking at various methods of adding IDE capability to a Spectrum I came across the “simple 8 bit” interface.
I had a couple of board made up cheap and here it is in all its simple glory



The card sits in the Z80 socket and the Z80 CPU sits in a socket on the PCB, all very simple.
Its only 8 bit and has its limitations but I look forward to experimenting with it

Works very well for my very limited testing but I’m not at all familiar with Spectrum’s so will probably take a little while before I can transfer anything “commercial” over the the CF card.
If anyone know a nice easy way to transfer images on the the CF card for use with the +3e ROM’s then please let me know
