Doing more research on games and software that can be run on an 8088 CPU/IBM PC/XT, although it is a bit tricky working out what actually runs on it sometimes, especially when there are some newer games that are designed to work with it!
Just to add to this thread, I'm also now looking for EGA/VGA cards that'll work with an 8088 setup; I actually have at least one in my possession, & as luck would have it, it also comes with a floppy disk drive connector (I think); somewhere I also have a board with serial and parallel ports, & potentially IDE ports too, leaving one port left for an additional sound card, if I want a game port for some reason, as the Book 8088 comes with an OPL3 card & a small ISA board in the config I chose!
Of course, the VGA card I have was recovered from Sekrit Place, so I have yet to actually test it, but it, & many other bits from there need to be thoroughly cleaned before testing, & potentially might need to be repaired somehow! The Sharp handhelds were also found in SP, coincidentally! I'm also looking at getting known working 386 and 486 CPUs for those builds, again using some parts from SP, but also stuff I've bought from elsewhere; my summer is definitely going to be interesting methinks!
