Yes, I have a Tyche in a real QL

But it’s using a chr$ Rom board which may not be what you mean

As t0nyt said - you'd need some kind of adapter board, as altough the ROM sockets are effectively wired in parallel, and have a 64K address space - they don't have a standard EPROM pinout that would support using a 27512K or Flash equivalent.

The Tyche is a 64K image compared to 48K for standard QDOS / Minverva images.

I have it as one of several images on a ROM switcher board.

And is it more-or-less usable ??

I haven’t tried to do much so far as you obviously can’t use QIMSI etc with it, so need to try it with a Floppy Controller

You can also use it with QemuLator. But it doesn't do anything earth-shattering. Stick with Minerva; it's definitely better.

i would like to make one functionable tyche , only for collecting purposes .

And it woks !!

now to find a sensible use for it

Got 3 minerva units left to use .

anyone got info about tyche TY07 ??
