Well, define effective? ;^)

Sorry - significant differences between models below:

Ultra 1 - fixed, uniprocessor, top CPU speed 200 MHz, 8 DIMMs, 2x SCA drive
slots (one accomodates 1.6" high drives), single SCSI chain, single UPA slot,

Ultra 30 - 250 or 300 MHz CPU, 16 DIMM slots, 2x SCA drive slots (both
accomodate 1.6" high drives), single SCSI chain, dual "vertical" UPA slots,

Ultra 2 - dual processor capable (170, 200, 250, 300 or 400 MHz), 16 DIMMs, 2x
SCA slots (1" tall drives only), single SCSI chain, single UPA slot, PCI

Ultra 60 - dual processor capable (300 or 450 MHz), 16 DIMMs, 2x SCA slots
(both accomodate 1.6" high drives), DUAL SCSI chain, dual "vertical" UPA
slots, PCI

Sounds like graphics are important, and raw CPU speed is important too...

With Graphics being a concern, I'd suggest either a U30 or U60, based mainly
on the affordable "vertical" UPA framebuffers like the sub-$20 Elite 3d-m3s on
ebay (no 256 color limitation, fast speed, etc.)...

I'd suggest getting a U30 if you can find a good one (incl. CD, lots of RAM,
300 MHz CPU, and a nice framebuffer). The U60 is great (I have a couple ;^),
but the cost is a bit high for a nice learning config relative to the U30.

A dual CPU U2 is a very capable machine, but the graphics options limit their
appeal as a mainstream desktop - they are great backroom servers, IMHO.

Of course, there are other options - if you have a decent spare parts bin,
there are nice "Cycle Quad 4" system bases on ebay for $75 that can take up to
4 CPUs, have dual SCSI chains, and I think are PCI-based... Not sure about UPA
slots though...
