At this point I'm just glad that my idea was not nonsense but turns out to be actually implemented in the design :-) And wow, that thing is small! A digital filter in the CPLD might help then, but that needs Flip-Flops which are usually not massively available in those kind of chips... Marcel ___ QL-Users Mailing List

I've already started putting together a clone using an Xilinx XC9572XL, which I have lying around. The Verilog file compiled from the get-go, I just had to remove the additional SS lines because of Pin restrictions in the small chip on my eval board.

That should be enough IO pins to connect an SD card which just needs SPI. Graeme ___ QL-Users Mailing List

Re: [Ql-Users] QL-SD new driver
Hi, There is no parallel port on the Gold Card. There is a Parallel Port on the Super Gold Card. But it is not bi-directional. Only works as a simple printer port. But maybe some output pins could be turned into Inputs.

I already designed an SD card device for SGC, Q40, Q60 parallel port many years ago. It even draws enough supply power by some tricks, no need for AC adaptor. Due to the slow speed I did not release it. IIRC it was like floppy on Q40/Q60 and even slower on SGC. SGC data lines are unidirectional, allowing only bitbanging. No PAR on GC.

[Ql-Users] Re-upping QL-SD new driver [OT]

I dont want to muddy the list with OT, but I think its only polite to reply: The Wire is a US TV series about the drug epidemic in Baltimore, and no doubt elsewhere in Americastan. (Its not for everybody, but is often rated as one of the better TV series of its time.) Id never heard the expression "re-upping" before watching it, so I assumed, wrongly obviously, that you were a secret admirer too. In that context re-upping means re-supplying your pushers (and if youre a junky, presumably, yourself) with drugs. Well, youre certainly keeping us QL junkies happy! ;) That's an unintended side-effect. Keep on dealing! :) Per ___ QL-Users Mailing List
