On the other hand, why do we have a system flag if you don't use it?
In my opinion it's not really nice to use more info for that, since "[compatible TI-73 - 92+]" is always bigger than (TI-73-TI-92+), you could even leave the 2 "-" out and make it (TI73-TI92+) to shorten it.
Well, (TI-73-TI-92+) suggests it's for the TI-73 & TI-92+ only - which is not correct in the case we're debating.
