Rom cartridges.

Hi.
Regarding ROM cartridges.
If I plug 1 into my QL and it transpires the cartridge is not for a ql - do I damage my ql?
What if the cartridges are for a tonto?
I've only had the ql 1 week and am loathe to break it.
Thanks in advance,
Rob

All of the lines except ground are 5V safe, so even if the pinout is different there's nothing that would damage your QL or the Rompack. There's a standard to the way Sinclair linked power and ground to plug in devices, so there's a very remote chance of that kind of issue.

Thanks very very much Dave.
It's good to know I won't be able to damage the QL.
I've got some ROM's coming, at least 1 of which is labelled such that I believe it is for a QL.
Some others are labelled with game names too, which I'm hoping are more likely to be QL than TONTO or OPD.
At least I can try without fear of explosion ;-)
A part of me hopes that even if the others are TONTO, the fact that the hardware between a QL and Tonto are the same in quite a few respects means they'll work in a QL.
Still it's not much of a gamble and it does seem as though at least I get 1 QL ROM.
Again, many thanks for taking the time to answer,
Rob
