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

The wire?
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! :)

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.

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.

Doesnt gold card have a parralell port?

That should be enough IO pins to connect an SD card which just needs SPI.

Ah, thats better, thanks :)

BTW, I forgot to add that the driver is for v. 0.82 of the 
interface. If you have v. 0.75, please holler!!

Hi all,

I've released a new driver for QL-SD that uses standard qxl.win 
drives

instead of Qubide ones.

It's for Minerva only, though.

You can download it from www.wlenerz.com/QLSD

Have fun.

I think bit-banging would noticably reduce the transfer speed.

Doesnt gold card have a parralell port?

That should be enough IO pins to connect an SD card which just needs SPI.

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...
