Re: Recommended maintance & MDV ULA Problem
Hi Martin! No harm in replacing the Cap in the reset cct, I'm sure. If the problem goes away after a further reset, it could be the 15MHz oscillator driving the ZX8302 ageing and not stabilising 'quickly enough.' But that's just speculation. As for the method used to select each MDV unit, I think I ...

Re: Recommended maintance & MDV ULA Problem
Hi Martin! I've never had a problem with RESET that required that Cap to be replaced - when I have hitn problems with reset, it was either down to the ZX8302 or something more fundamental with the main ZX8301, but replacing the Cap is a simple and cheap enough operation to eliminate it. I am in the ...

Re: CST Ram Plus eproms - CST QDisc v4 issue
Hi all! If indeed the v4 board uses the 'scrambled' method for data and/or address lines and if the ROM was programmed in a std programmer from a straight image, then therein would certainly lie one probable cause... A quick check would be to PEEK_W from Basic the base address where the CST ROM is e...

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.
PM me and perhaps we can figure out how cost effective shipping to/fro would be.
Or are you planning to attend the Dormagen event in May?

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...

Re: Anouncement for the 40th Anniversary of the Sinclair QL in Dormagen (Germany)
Hi Peter!
Unfortunately, I need to back Sunday evening - both for work and also as my 16-yr old is in the midst of his GCSE exams, so will be flying back around 4pm from Dusseldorf...
