Sinclair QL: ROM switcher with a FLASH !

[genny_flick]

Hi, here a very simple project: a ROM switcher for Sinclair QL. I have used a FLASH 29F010 able to store 256Kx8, so I have programmed it to have:

1) Original JS ROM;
2) Original JS ROM + Toolkit II;
3) Minerva ROM;
4) Minerva ROM + Toolkit II.

Using jumpers is possible to choose configuration. It use round pin to preserve original sockets ROM.

Does it interfere with the external ROM at all?
