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

Happy New Year to you too

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 ...

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've no idea ...

Hi
Happy New Year.

i bought a willeam pcb5.0E2020 from AliExpress so I can program ROMs but unfortunately I cannot get it to work.
It is running on an old PC with Windows XP and using an external power supply rather than the USB power.

Possibly have duff Minerva rom so will try and get it reburnt.

thanks

Hi
I have an issue 5 and an issue 6 QL.

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 ...

very interested too.

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
