@Siggi Sorry for my late reply, I am currently very busy in my private life. So I cannot follow the discussion in time ... >is it possible to use 2 Mr X. boards (no Zxpand), one "normal" and one with the new gals? If yes then I would like to program a gal by myself. Yes of course. The new GAL code (...

Hello everybody, @ yerzmyey Congratulations! Fantastic sound! Really fucking ;-) impressive!

>> I 'presume' he would not plan on using the MrX interface and the ZXpand-AY at the same time! Hmmmm, I will offer another GAL with different Adress decoding for the MrX so that it is possible to use it in conjunction with the ZXpand (or two MrX at the same time). Alltogether this would make MrX + ...

Another suggestion ...... why using an SD-Card?

I could imagine to use an ordinary PC with printer port, connect it with the sound cards ports and transfer the files from the PC byte by byte.

During the delay loop, there is enough time to read several bytes. .....
