"..because PCMCIA slot in a 1200 is only 16 bits wide and nowhere near as
fast as SCSI or IDE."
Hmmmm. This is the second time I've caught this error in this thread.
_Check_your_facts_.
PCMCIA is "only" 16 bits, true (just like Zorro-II)… but what gives you
the idea that it's slower than SCSI & IDE? And are you telling me that
Zorro-II (16bit) is too slow to get top SCSI performance? What about all
those A2000 HD boards?
I'm not arguing that CD32 should be connected via PCMCIA, I'm just
nitpicking on your false impression of PCMCIA's speed.
If PCMCIA were slower than SCSI, then those PCMCIA RAM cards would make
an Amiga 600/1200 look slower than a TI99/4a! RAM is by far the most
demanding add-on in terms of speed, and PCMCIA was clearly designed to
handle RAM (albeit , 16bit RAM).
Bottom line: PCMCIA is plenty fast enough for all but the fastest, most
expensive hard drives (and CDROMs are much slower than hard drives).
PCMCIA is good for RAM on an A600 (16bits) but would slow down an A1200
because of the 32bit-wide CPU. The vast majority of hard disks and drives
are not as fast as PCMCIA.
