Comment by Paul Collins (pi314aussie[at]yahoo.com):
Where is the 486 DLC2 -50 and the 486SLC2 -50? There was a turbo/upgrade card for the IBM PS/2 model 30/286. This IBM was a crap computer in standard guise. With the upgrage card raising the bar to 486 DLC2 -50 (but only running at 20MHz), the computer was still crap. Yes, the 486 DLC2 has the pin-for-pin out of a 386DX, and the brains/smarts of a 486SX2 inside. But with its 286 converted to 486, and its 10-clock doubled to 20-clock, the "real-world" MS-Windows apps. were only 10%-50% faster. Sure our benchmarking apps. agreed with the 8x (800%) boost, but those MS-apps. didn't run even 2x (200%) faster at all. So I say, once a "boat-anchor", always a boat-anchor. I read about the 486SLC2 -50 being a pin-for-pin out of a 386SX, with the brains of a 486SX2 inside, but never saw it implemented in any desktop computer, only the IBM laptops! The last of the last 386SX m/boards that I saw, were running the AMD386SX -40, with motherboard cache (8k). Since the AMD didn't have L1 cache, but the Cyrix/IBM did have L1 cache, why didn't they make no-name desktop m/boards with 25MHz clock for the SLC2 -50 chips???
