The Sinclair QL Forum

Many years ago, Digital Precision sent me a pile of microdrives to see if I could break the protection on them. Chess was not one of them. Most were pretty simple though, you had to disassemble the code, find where it accessed mdv2, then NOP out whatever checks it did to prove the master was in mdv...

Thank you! And do you know how to bypass the protection tonplay chess. I have the original master microdrive. The same with West, Zkul and Graphiql

If you use WCOPY flp1_ to flp2_ You will loose the file dates, and it may miss some oddly named files. A program I have used is EMT4WIN http://www.vogonsdrivers.com/getfile.php?fileid=1081 It's a windows program that converts PC and QL floppies to a disk images. Just pick a standard image file form...

Hi again. Which would you say is the best way to copy old floppy disks to a PC to preserve them? A simple wcopy flp1_ to flp2_ being flp2 a floppy disk image? or is there another file transfer program that verifies bad sectors and tries to fix them? I have read all the forum topics about this and Dw...

The DMV here accidentally used the Chile flag instead of the Texas flag for many years without noticing. Hahaha That's hilarious , I had never heard that before. My primary school at a baptist school is still alive and lives near San Antonio. Well, you can throw in a membrane just in case, with the...

Dave: I've read most of your posts and I want to congratulate for your hard work for tne QL community. I'm interested in the Minerva Rom card and the buck regulator. My psu is an original one and it sounds like its working too hard. I have my BBQL since 1985 and it works fine. If I open it to instal...

My guess is that the cable needs to be upside down. Try DIR flp1_ - if that does nothing, then try DIR flp2_ If DIR flp2_ works, then the drive is set as DS1 (not DS0) - there are probably some jumpers on that drive to change it over. Thanks Rich I tried both dir and it waits 5 seconds and then say...

Hi, everybody. It’s been 5 years since my last post. Busy with beggining a medical research facility down here in Patagonia. Now trying to use my BBQL again. The thing is I want to resucitate my Cumana floppy disk drive with the cumana interface. Since it isn’t a pc drive I figured I could use a st...

I wonder if it would need a twist in the cable? I'd love to hear more about QL'ing in Patagonia too! Thank you for your answers. For the pc floppy I twisted 10 to 12 and it used to work. But that connector broked. For the cumana drive I use the original straight cable but in the middle conector sin...
