Re: OPL2 (3 ?) sound for your QL through parallel port

Simple googling shows QL parallel port exists as a DIY project. I haven't checked if it uses one serial port or both, but mechanically, it means a tiny interface plugging at the back of the QL, and at the back of it, this OPL2 device. Again, the issue of converting serial ro parallel signals is one ...

Re: OPL2 (3 ?) sound for your QL through parallel port

It could be trivial to add hardware for this, but someone would need to write the driver... :-( Not a mammoth task if for non system usage. Certainly more tricky otherwise, but again we are not talking about sthing undocumented which is going to be a torture to adapt. Also, I do not think we need i...

Re: OPL2 (3 ?) sound for your QL through parallel port

I feel very lonely when I read that, as though instead of trying to give something new and cheap a chance, it is better to stay with actual : - no hardware for a stock QL - there is some hardware, having more and / or better is sthing to absolutely reject and trash. Btw the code to play OPL files is...

Re: OPL2 (3 ?) sound for your QL through parallel port

Maybe stupid question, but what is the use of another sound system? Wouldn't it make more sense to to use the existing QLSSS so applications run on as many platforms as possible? What is the advantage over QLSSS? There are many : - it can be an additional sound system (in fact for a standard QL, I ...

Re: Q68 New users and general usage thread

FYI: Parcels2Go tracking is useless. If shipping internationally, it says "collected" and you have no idea where your package is. I have contacted them and they do not even have a clue where it is. I will happily pay 2x the shipping cost to have even basic tracking functionality next time...

Please keep in mind that 1 cycle is only for register operands and fast RAM. External operands and slower memory will add additional cycles.


1st thing to do when I get my boards is doing some tests.

If it is a revamped C5 with QL assisted control, remember I have about 300 spare tyres available ;)
