The EMatrix A1230 is a decent and reliable card. It's far more better than Jens his ACA-crap (wich isn't plug 'n' play).
This is a very dishonest statement regarding the Indivision ACA cards. I've got one of the original ACA1230@56 cards and it's the fastest 030 card I've ever owned. Works with everything and is PCMCIA friendly. If you're referring to the fact that one simple line must be added to the startup-sequence to fine tune the card then your statement is exaggerated to say the least.
My only wish is that it had an option for an FPU.
