Yes, think you can do it simplistically by piping the console, How remote is remote? You want to be outside your home network? The problem mostly is security, all the old stuff has been cracked to hell and back with numerous vulnerabilities and exploits.

IR file transfer can be quite fast. ... If you've got another system with it, was common up to PIII machines. I like C&T graphics, they are usually fairly fast for their era and don't have too many quirks or deviations from normal. I still can't figure out how Intel bought them up then produced such …

So what might be going on, is that the motherboard doesn't have enough refresh line capability to supply a refresh for more than a handful of RAM chips. Now in some BIOSes, there is a cryptically named refresh strength setting in the advanced chipset setup, maybe playing with that might get you …

The PlayStation looked good/fast because it ran at low res, only up to 640x480, it had no OS and driver overhead because it was single platform so games could be more on the metal and not need to consider driver standards and differences in hardware. The 33Mhz MIPs CPU may have been faster on a …

Was that the board, there was 5 voltage jumpers and the manual just had the 5 settings... BUT there were multiple undocumented voltages available by using 2 or 3 jumper caps at once, instead of the one?? There use to be a site about P2B mods and tricks, but dunno if it's still around.

I only really hate it for the fact I can't overclock the FSB much past 66mhz. I reach a freeze by 75mhz. That might be the CPU, the early PII 233 and 266 didn't overclock, I mean really didn't, had a board that had the 68Mhz setting, and had a 233 and 266 crash at that speed. Then came a die shrink …

Yes the P2B was a classic. One of the boards known to run Tualatins well. I bought a box of "untested" motherboards from somewhere cheap in the early oughts, and had several P2Bs and close relatives in there. Yah, it appeared "untested" meant tested, found faulty and some parts robbed off some, …

You can use whatever RAM you like, but you're not going to get data into or out of a 486 faster than it's base clock time bus width, divided by 8 for bytes. Which is 160MByte per sec at 40Mhz... which is what decent speed FPM RAM with no wait states should be doing anyway.
