Hi,
I used to have one of those MTEC cards but for some obscure reason it was not PCMCIA friendly. When I installed 8 MB the PCMCIA slot was unusable.
A friend of mine had no trouble so this problem might have been just my card.
8MB is max for those cards that's for sure. So I don't think it is that valuable. Go for a faster card. 030@40Mhz is nice. Can even play some 3d things at decent framerates. But an 040 or 060 is definatly the way if you realy want a powermonster.
Regards,
Erno
