Re: schematics for floppy disk interfaces

Hi,

I will see what I can do with regards to the photograph.

I have copied the jumbled rom code to a file, I will determine the correct unjumble sequence of address and data lines and decode the Rom, I will save the QL Rom slot where the Rom is located, for comparison.

The Rom is v1.18

Re: SMS2 and STELLA

I am not sure what I am looking at (FPGAs that is). But here goes anyway:- The SMS2 PEROM has a capacity of 128Kbytes. This is large enough to contain the OS and its drivers, the Thing system, user interface, QPAC2, SBASIC, an editor, CLI etc. etc. The Stella kernel is more powerful than SMS2 and s...

Re: Target for major new QL hardware

Hi Peter, Looks great, fitting nice into the QL Case. I do not need floppy disc drives, SD Cards are much better. Besides, there is no Floppy disk interface hardware, no floppy disc driver software and I doubt there is any one to write the driver software. I use FLP images on an SD Card and use FDI ...

Re: QL-SD driver 1.10

... as well as sQLux, Q68 Ummm, no. "Both" in the sense of "byte-swapped" or not. As far as I'm aware this is a QPC-only feature. Nope, I implemented byte swapping in sQLux years ago. I am a little confused, the QUBide files from my QL-SD Interface, are read/write on Q68 using t...

Re: Replacement for 68008

Hi,

Could the 68SEC000 be connected to the QL 68008 socket with an appropriate DIP to QFP adapter board, with the possibility of using it own un-contended ram?

Ah ok. Unlikely setup on a PC, but I understand. Well, even better that QPC can do both ;-)

Re: QL-SD driver 1.10

HI Marcel,

I loaded 2 QUBide image file that were used on a QL-SD v1 on QPC v5.0.2 with SMSQ/E v3.38 which worked really well.

Excellent work to get this working.
