This week I finally created a Facebook page dedicated to my technical hobbies including the Sinclair related projects:

I will try to migrate this blog to that Facebook channel in the future, to have everything at one location.

Betadisk (original) schematic and pinout 
Monday, August 5, 2013, 12:22 PM
I was searching for a betadisk interface schematic with connector pinouts and found it on World of Spectrum (only).

But I think it's useful putting it online to be found more easily.
So here it is!

Disciple GAL files 
Tuesday, April 2, 2013, 08:02 PM
It's about time to put the GAL files online for the Disciple disk interface for the ZX Spectrum.

These can be used to replace a defective PAL chip.
PAL chips are obsolete and not all universal programmers are able to program blank PAL chips.
So it's far more easy to use GAL chips which are pincompatible.

Be aware that Disciple defects are often caused by bad soldering contacts!! Resolder all contacts before putting in the effort of swapping the PAL's; that solved the problems with 2 Disciples I had my hands on.

The link to the GAL files is within this World of Spectrum topic.
