I got some further results today which are quite positive.
Using a spare IDE compact flash adaptor I found in my junk box(!) I was able to get the Qubide PARTITION_EXE program working again. This card has two CF slots on it, so I plugged in the 4GB card and a smaller 16MB card from an old broken camera and they seem to work OK together as a Master/Slave pair. The only slight snag is that the two slots aren’t labelled as to which is which, plus the jumper settings are printed on the PCB, but no pin numbers! Trial and error…
It (the IDE CF adaptor, not the broken camera) has the opposite gender connector, so will need a gender converter to install permanently. Anyway, I’ve ordered a dual IDE CF adaptor unit with the form factor of a 2.5 inch IDE hard disk, which if it works should fit perfectly inside the Minis-QL case in place of the 20MB hard disk, if I then get another 4GB CF card one can backup the other!
With this unit, I was able to create a second partition of 1.8MB (2MB+1.8MB = 4GB eh?), so the next step is to try to make more, smaller partitions so as not to be so wasteful when saving relatively small QL files in large block clusters.
It’s quite a while since I tinkered with QL hardware like this and it makes a nice change from programming!
