The Sinclair QL Forum

In that case, simple ROM switcher seems to be the solution…

In my opinion, the only essential software, which does not run with Minerva, is the game Vroom.

I expect that the SMS2 cartridge is pure ROM cartridge.
But I'm not sure, is its content available anywhere?

XChange is more ptr_gen friendly than old Quill.

And there is brand new ISO 8859-2 font.

Typo?
NFS_USE MDV,n1_mdv1_,n1_mdv2_

VROOM is incompatible with Minerva ROM.
Probably the only QL game with this incompatibility.

What ROM do You have?

Moreover, there is ZX Spectrum with 528 KiO RAM, with Interface 1 (including NET, serial and connector for Microdrive) built-in.
And running CP/M from Microdrive

You can dedicate 256 addresses in the ROM area for “writing”.
Reading any of this addresses writes the corresponding value (0 to 255) to the register of device connected to the ROM port.

Not quite true.

WTV without parameter restores to MODE 4, not 8 (on my QLs, at least).
What is what I use, resolution to fit onto normal TV, but with more characters per line like in WMON modes.
