haha, thanks - did have a sense of achievement to it - especially when my QL booted successfully with the burnt ROM.

Re: programming eprom with willem pcb5.0E2020

I've removed all printer software and anything I can think of that would touch the parallel port. Could the BIOS that usually has three parallel port settings make a difference? If it is passing parallel data it might be worth belling out the cable data lines. Do you know what is in the EPROM you a...

Re: programming eprom with willem pcb5.0E2020

I am trying to read/write 27C512 and 27C256 eproms. I've managed to get it so I can half read a Miracle systems rom chip. In the buffer I see text like "...0F...acle....stems..." so it looks like it is reading some of the data but dropping or corrupting some. must be a timing issue but I'v...

How to install Minerva ?

Hi I have an issue 5 and an issue 6 QL. The issue 6 has QIMI installed too. I cannot find instructions on how Minerva is physically installed into the QL, especially with something like QIMI installed already. Maybe I am dumb and missing something obvious but do I just plug the daughter board straig...

Re: QL-SD ROM

very interested too.
I have a Miracle HDD system that connects in this way but unfortunately the disk in it died, so this would be brilliant.

Re: Sinclair QL vDrive - Load & Use Applications and Games - Video

vmap only allows mdv1 and mdv2 to be mapped to the internal drives, or ext1 or ext2 - so mdv3-8 cannot be mapped to mdv1 from what I can see. That is not true - vMap modes 3 to 8 will map the internal drives as mdv3 -8 See the chart in the vMap manual https://vdrivezx.files.wordpress.com/2017/08/vm...
