The 286 was just used as a fast 8088 most of it’s existence but that wasn’t what the market really wanted, in fact they were complaining about it already in late 82 which delayed the chips release as Intel fixed extended memory (protected mode) and multitasking support. I can't fault the Intel …

Fic 503. I wanted to upgrade to a kick ass Super7 board with AGP and a high performance K6-II that gave intel a run for its money that I could upgrade to a K3-III some day. Instead I got a cramped layout, jumper hell, instability, and the dreaded Via 4-1 drivers. Install them again! Do it in the …

Switching the RAM is a good idea, but running MemTest86+ to verify would be even better. Agreed. That error suggests to me that the disk controller is having trouble doing UDMA. I bet if you run memtest86+ overnight, I suspect that it will find an issue before if finishes 10 passes. Once you can …

Turns out people really liked their legacy software. Maybe the 286 protected mode was a necessary step in the learning process to understand what needed to go into the 386. And maybe the first few 286 chips were just to slow to really benefit from prememptive multitasking anyway. If your …

What about the Quadro K2200? Same specs as the 750Ti but just a bit slower stock RAM clocks. There are modified XP drivers available for it. It is also single slot. And to top it off, it is readily available and pretty cheap. The K2200 seems like the sweet spot for Price/Performance/Power …

Just an update... I gave away the 286 board (but I kept the IIT 287, since it was missing from my collection) . I got a smaller board based on the Headland HT12A chipset and... what a difference! This board allows me to choose between 0 and 1 wait states. With 1 wait states performance is more or …

Well yah try them alone either way as then we rule out flaky modules maybe.

In 93 and 94 maybe, many more P60 selling... but then I wonder if they had a glut of P66 and they got sold off cheap enough for a lot of people with 60 to spring for a 66 in 95 or so, putting a lot of P60s on shelves, and then again when the Socket 4 overdrive came out. Because I think the …
