Re: Recommended maintance & MDV ULA Problem

Re: QL-SD jumperable

Ah, OK. Bit of a schlep from London...

I have the equipment needed to reflash the QL-SD device and have made the same change on one of mine successfully.

Re: ntsc sinclar ql schematics ??

Hi again Peter! To be fair, the UK keyboard was already pretty much based on the US layout - something I was surprised to discover when developing the extra language maps for the Qbase :-) Did you finish any of them? No, not yet. I developed a flexible framework to support up to 8 distinct, user-sel...

Hi Peter!
