Yes, definitely cumbersome with changing jumpers. However, I have plans to build an external jumper switch-box for all controllable jumpers (audio/ video/ motherboard) when everything is finalised, hopefully. Otherwise, I personally wouldn't bother to open the case to change jumpers. I had exactly …

Upto Socket 7 boards exist with working Turbo switches. There maybe newer as I've seen BX boards with them, but the Turbo header doesn't function. Working headers don't all work the same way, where some just seem to halve FSB, whilst others have more significant impact and reduce speeds to 386 and …

Jane's USAF, or Jane's IAF for example, the game has no in-game music at all. For atmosphere purposes? They're meant to be simulators, and plenty lacked in-game music from that era. Last time I climbed into a fighter jet, I too was disappointed by the lack of in-flight entertainment. Probably for …

You should recap the power leap adapter for the cpu, on mine the regulator died and killed the cpu because capacitors are failed Thanks for the heads-up, and sorry to hear your CPU died. These aren't cheap anymore. This is good advice with any old hardware. My soldering skills aren't the best, and …

Multiplayer online games predate the original IBM PC. These games were text-based MUDs (Multi-User Dungeons) that originated in the 70s, and the first one on XT I can find is Scepter of Goth, circa 1983: https://dwheeler.com/scepter-of-goth/scepter-of-goth.html

TG77 can do things the FS1R can't and vice-versa. Besides the 6 FM ops vs 8 FM ops, the TG77 can modulate AWM with its Advanced FM synthesis as well as import samples (RAM cards) and use AFM, whilst the FS1R can do Formant synthesis which sounds like freaky vocoder stuff.

^^ 16 MHz was an undocumented FSB setting on the board, and before de-turbo was applied. I distinctly remember the 16 MHz number, and this was found by starting at 66 MHz FSB, then downclocking the FSB incrementally using the boards dipswitches - 66, 50, 40, 33, 25, 16. Then the fan was disconnected …
