Oi Pete you rascal you, everybody KNOWS you can only get Apocalypse on magnetic tape. Why, you can't move in my house for all the X-Com Apocalypse tape drums....
For those with the vinyl edition of the game(it's pirated you know, generally found in obscure parts of Asia that you've probably never heard of), how about getting a ps/2 (the plug, not the Playstation 2) mouse? They are still in circulation, and some even come with crusty old dos drivers that should work, but the windows drivers might work too.
Oh and for those with the *ahem* VHS version of X-Com Apocalypse (another pirated version of the game) you could even try one of those new fangled serial mice.
I can't seem to find a mouse that'll plug into the LPT or midi ports though... But no worries, I'll be on my guard!
I think I might need a bit of therapy...
