This discussion brings up what was the cutting edge to consumers in a given year? Harris had 25mhz 286’s sampling in low volumes in 1987, but did anyone actually get one that year? Likewise 6mhz 8088/8086 existed right in 1981, but did anyone use them? 8mhz existed in 1983 and an early not ibm …

Yeah p54c would probably be okay with that. I had a batch of PCCHIPS M571/M569s and some old k5’s I discovered I could set voltages above VRE by jumpering multiple voltages at the same time. My k5-133 would overclock to a pr200 at 4 volts My guess is the original Pentiums wouldn’t hit 250 without …

Most of the “odd ratio” monitors including ultra wide don’t support “docking “ of different video inputs. If they did support it on their own without special software you could end up with interesting tv/Pc/game system auto configs. There is one “phone factor “ vertical TV that has some docking …

Speed and lag was period correct the engine had no real speed regulation. Unless you play a level I can’t say if it’s too fast but it looks on the fast side to me. 286-16 is about “right” unless you have twitch reflexes

Did any IBM PC compatibles use the v33? I always thought it sort of pointless as it wasn’t pin compatible or bus compatible and was like a 286 without protected mode Wonder if the extra memory would work with himem and if a20 and the high irqs/ dam worked?

Yes it is, possible but was sometimes buggy or occasionally the cards would have resource conflicts. Was also possible although more difficult under Windows 95, 3.11 and even dos CGA/MDA being the first dual monitor configuration

But isn't that MDA/Herc or mono CGA modes to the monitor and not VGA modes, which I thought was what was implied. The monitor type defines the video modes available by the VGA card. An MDA monitor can be used for EGA monochrome mode (640x350 mono) sometimes, I vaguely remember. That's because HGC …
