Re: QL-SD card project
Hello Gertk,
this is 100kHz FM encoding.
I had done some work on it here:
http://www.qlforum.co.uk/viewtopic.php?f=2&t=269#p1616
Unfortunately the image I had uploaded to the forum is gone !?
(I am sure I had not put an external reference to the image.)

Re: Faster/wider CPU...
Hello Dave, as you would like to use the 68EC000,a first minimal expansion you could build could use it in 8 bit mode but with the clock doubled together with a 512KB sram for the address range $40000 to $BFFFF. So to say,you would have a 68008 but with 15MHz when accessing the expansion memory. Con...

Re: Winter QL'ing

Re: Using Microdrives Today
Hello all, the "QL advanced users guide" book has also informations on the microdrive format in one appendix.It is very informative. The microtapes are really a pain when you only have a plain QL. I have only seven microtapes left functioning beside the four originals and it really gets fr...
