I was just wondering what would be involved in burning my own EPROM
with my own set of routines for plugging into the ROM port (like
TK2), has anyone done this? what sort of kit is involved and how much
are we talking about here. Also would I have to make my own pcb or
can they be bought/manufactured. This is all for the original QL of
course.

Hi Lee,
There is a special header for EPROM code, but I don't have it to hand...
I have plenty of spare PCBs however :-)
I remember the BBC micro have several Sideways ROM pcb's produced, along
with software.
Which allowed you to switch in to a different set of ROM's.
Would that hardware be possible with the QL?
Yes it is - I have seen one of those. I forget though who made them.
It was nothing sophisticated - just a switch to divert the chip select
lines.
Tony
