The Sinclair QL Forum

Well, there are at least 3 different SD card solutions in various stages at the moment.

The one which connects via the microdrive socket is probably the best solution going forwards, as it does not tie up any of the QL's main expansion ports.

The Q68 has always been an interesting project for me.

You should be OK with this QL for a while - I think it has a new membrane in it already ! The main things to remove to see the PCB are the two molex keyboard connectors, and the set of LED wires (6 in a strip) - although they are a REAL pain to get back in and one will normally come loose as you pus...

If you can send me some proof of ownership (by email), I will send you the necessary files - I can't remember if q-emulator can save to microdrive image files (I don't think so), but I can let you have them as a QL Zip if that is any good?

The problem with 128K maximum, is that some of the later software is bigger than that already!

Right - Simple enough. I wasn't realizing that you can mis-use higher MD drive numbers for a control session. Again: Very interesting project! Keep on with the good work! Tobias Yes - this could be a possibility, as not many people would be using mdv8_ for example, but there are a couple of issues ...

Hi Rich and welcome to the forums. I see you must be the one who recently bought that QL from another one of my customers - he is unfortunately having to sell up his collection - some nice pieces in it too! Actually, I think that this QL may well have come from me in the first place :D A CUB has to ...

Yes - this looks good work - the main issue going forward is going to be to try and get around the 255 sector limit. I would also aim to have this as a replacement which could fit in either the QL's microdrive slots, or a ZX Spectrum microdrive unit - that would open it to the widest possible market!

Surely the mechanics of how data is sent to and read from the tape is the same - after all it's the same ULA and you can use a Spectrum microdrive unit with the QL - it's just the way it's stored on the tape which is different.... Didn't realise there was anything in the Advanced QL user guide - - i...

As I said, the best bet is Ian Logan's book - ftp://ftp.worldofspectrum.org/pub/sincl ... veBook.zip (21MB) - look at page 28 onwards for details

Daniele has a much easier job - he just needed to decode a microdrive image. I think that what is being sought here, is a means of decoding the signals sent over the actual microdrive port - ie. the electrical signals, which must be interpreted by the microdrive ULA itself to work out what to do wit...
