probably not, the USB card would have to have Solaris specific drivers for it
to work right. which i'm sure don't exist. oh well. maybe it's time to
break down and buy a SunBlade 100. oh wait, that takes money, i'm completely
short of that. :)

my sparc20 only has 2 serial ports, which kinda sucks, but it's real easy to
get a large number of serial ports on my VAXentoys. although that isn't real
useful for the type of stuff you need to do, but then, we have different needs.

yeah, but since it's so easy to find what you are looking for in native USB,
that shouldn't be a problem, right?

DSSI is kinda like SCSI, used in the "big" VAXentoys (VAX 4000 and up? someone
correct me if i'm wrong, but i don't think i am) and rather nice. sadly all
DSSI disks are rather slow since none of them are real modern, and so, usually
5400rpm and older, bigger, slower, more heat creating and more power consuming.
but they work real nice, i've never had any trouble with them anyway.
MFM/ESDI can both be a giant PITA, no, s/can be/are/ but they are what you
usually find on older boxes. both of my PDP machines have MFM and my IBM RTs
both have ESDI disks. both are a PITA to find as well, so once these die,
i'm pretty much up shit creek without a paddle.

either way, you can't beat IDE for the price per MB. performance isn't so
shabby anymore these days, but reliability isn't good from what i hear, and
you are still very limited to number of spindles in a machine. not a big deal
for your average desktop box, but that's not what i specialize in. :)

3D acceleration? uhm, what's that? :)

i use the onboard SX, a GX and a TGX. i don't think any of them even know how
to spell matrices, let alone transform them. :)
render video frames faster? my SX can barely keep it's head above water. :)
