The best/cheapest way to get 2x 400 MHz CPUs maybe to find a system with them stuck inside... I recently picked up 4x 360 MHz CPUs for an AXmp system, and they were just under $100 for the set of four.  You need to be patient, and not just look for the x1193A code in your ebay searches (400 ultra sparc might be good) - remember not everyone knows about the "X-codes" to list that info.

Registered == Buffered, IIRC. Compliant means the RAM matches the requirements for PC133 speed ratings.

Yep, 256 Meg pieces seem to be a practical size (cost vs. usefuleness) - 512 Meg pieces are cost-prohibitive in most cases. Again, keep an eye out for a slower system with lot's of RAM on eBay and see if you can get it cheap - you will find in many older Sun systems the "Sum is worth less than the parts" - many times complete system selll for less that the value of the RAM, CPU, or HD alone...

The controller chip is slow, no software can really make it better than it is in Solaris 10 (I think there was a patch early on because the software was broken too). Adding a faster drive will simply allow you to "max out" theslow performance of the bad controller implementation. Cheap SCSI cards are available, and with a reasonable SCSI HD, your performance will improve vastly. (I recently bought an Ultra 30 on eBay for $30 simply because it had a 300 MHz CPU, 2x UPA framebuffers, and a Sun SCSI card installed. I am going to strip it down for the parts and put to gether a minimal system from my left overs.) 120 Gig HDs are easily found for $30-60 after rebate on almost any weekend - they are fine, but don't rely on them for a "massive" speed increase - it will be a nice little "bump" up in performance...

>4) what drive speeds won't be too hot for a blade 100?

7200 RPM seems like a good, safe choice. 10,000 RPM may be a bit fast, based on the comments of others.

>5) lastly, there is a reference to the 'silkscreening'. does this refer to

>lastly, thanks for all the very useful guidance.

That's why we're here...
