Re: QL wont work

Hi - quite possibly - but replacing it with a working 78x05 won't cause any further damage and will give you a clue as to what might need replacing thereafter :-)

Re: QL wont work

Hi Traindriver So, sounds like the 5V regulation is fried. If that 5V is being generated by the standard linear 78x05 regulator (screwed to the black fin-heatsink), then they are easy and cheap enough to replace. If you have instead one of the various switched DC-DC converters mini-boards fitted in ...

Re: QLSD driver testers sought

Hi Tetroid I too was stumped by this behaviour a while ago, until it was explained in another thread :-) For this reason, I often include a WIN_USE 'win' in the BOOT file that is run from any medium other than WIN (FLP or else a virtual ROM 'BOOT' device that I use some on of my QL units.) In fact, ...

Marcel's new QL-SD interface...

Just wanted to say how impressed I am with Marcel's revised/re-released QL-SD interfaces! Just received them today (double-card and a micro-SD variant), carefully and conservatively packaged - only a couple of days after shipment and the build quality looks excellent. I'll post again after actually ...

Re: Overview of QL SD / CF Solutions

Hi Paul Nice set-up! You asked "what is the use of the (undocumented) "JTAG" connector in the middle of the board" As I understand it, the CPLD (or FPGA) that Tetroid has designed at the heart of his expansion card can be re-programmed 'in-place' via the JTAG connection and a sui...

Re: QL-SD problem - help needed

Hi Andrew Further to the guidance given earlier, you might want to read the installation section of the Minerva Mk1 (or Mk2) ROM replacement as it specifies exactly how to convert an Issue-5 configured for EPROMs to work with the Minerva daughter board - the QL-SD simply takes the original Minerva a...

Terrific Marcel!

I'll test this myself over the weekend.

Can't fault your rapid maintenance release-cycle!

Re: QLSD driver testers sought

Thanks Marcel! If that is the case WIN_CHECK seems to work fine and you need to backup your image files, re-format the SD and copy them over again as they seem to be fragmented. I was careful to copy single WIN files across to the SD card one at a time following a fresh format, but will try this ste...

Hi Norman

I must leave that request with Tobias as the author, but agree that, if he's willing to, it'd make a very interesting article to augment your already highly interesting periodicial :-)
