The Successor - 9577-DNA
8570's are 'way cool but 77's rule

This is a wonderful machine. And I've recently had the chance to make it an even better critter than it was. It's a 33 Mhz Bermuda-board 9577, and it's always had the planar limit of 32MB RAM, but the processor's been upgraded to a 33/133 Kingston Turbochip (AMD K5), and I've replaced the original XGA card with an XGA-2. Storage capabilities have grown with the addition of a 200MB IBM disk in addition to the original 540MB Seagate. Also added a CDROM II and a M-ACPA card, to round out the hardware improvements.
This has been for the longest time my machine of all-work and it does the job remarkably well. Has been run consistently under OS/2 Warp 4 and (despite my occasional attempts to do something incredibly stupid) has never TRAPed once. Under the ol' Intel 486/66 performance was pretty good - but did noticeably improve with the new AMD chip. Biggest improvements (of course) seemed to come by way of floating-point math: my SETI@home work unit processing time dropped & FP-intensive apps like TSPG became much more responsive. The XGA-2 card had much to do with that performance increase as well... and of itself was as impressive as the processor upgrade alone.
I realize that the later 77's - the Lacunas - are generally considered better bets with their L2 Caches, S3 video, IDE support and greater RAM expansion possibilities. But this 77 is an eminently capable of doing everything I've needed done... and then some. Now, there's a lot of folks out there that would be... not impressed by this machine. Frankly... I don't care, it answers my needs for a rugged dependable box. I don't see blue-screens-of-death, Unrecoverable-whatsit-exceptions, or have problems with the Registry (what registry?). Its a nice way to live:)
The kicker is I got this prize for US$25... Thank you IBM!
For Grins & Giggles, here's Sysbench results on the '77. The results posted for the 9577-DNG were acquired from a hardware twin of my own machine that I set up for my grandfather, but with Warp 3 as the resident OS instead. Thought the benchmark differences between Warp 3 & 4 on identical hardware were... interesting :)

You can't consider this good literature but I can't forget my first 9577: Requiem for 9577-DNG 23THNLT
