One with a microcontroller is active yes, but active does not necessarily mean microcontroller, as it would in some conversions just be doing level shifting or analog mode signal mixing or massaging, or more complex stuff with shift registers and logic, maybe implemented in a PAL or custom ASIC that …

I don't think you need something active as much as smart in that sitch, it needs to process and separate the signals, then turn them into PS/2, so microcontroller board that does USB host mode is probably going to come in.

An old early 90s monitor, you may have to twiddle knobs for the perfectly centered and screen filling picture every time you change screen modes. You may get fed up of this and find a compromise setting where at least nothing is disappearing off the edge in each mode. With buttons and likely an OSD …

Black to most negative and red to most positive, so black or normal 0V connection to -12V and red or normal 12V connection to 0v.

With heatpipes orientation does not matter. The liquid is transported using the capillary effect. A thermosyphon relies on gravity to transport the liquid back to the heat source. The condenser has to be mounted above the heat source/evaporator for it to work. I'd go with shouldn't matter because …

A PC that is 10 years old now can still do most basic stuff I need from it today (and quite literally so). This feat was impossible when you were to try something like a Pentium 60MHz from 1993 with software made for an Athlon XP 3200+ from 2003. That difference is just insane! Now 10 years PC …

A fair bit was done in software emulation on like PDPs and Vaxen, though they tended to call it simulation then. So then there'd be "some" code ready to try when the first hardware sampled. You can find developer "simulators" for old 8 bit CPU/MCU on some of the old MSDOS ftp mirrors.

Button it up, stress test it, and see if it can take another 10-50W or whether it's already over the edge power and cooling wise.
