Oh, but figuring all that out? That was what made it all rewarding in the end. And if you think there were no set standards on an "IBM PC Compatable", then you, sir, are rather oblivious. They're all based on the original IBM Model 5150 with its Intel 8086 processor. Just like the Amigas (well, most of them) and even with the MSX series, things got faster, looked prettier, and sounded better as time went by, but it was still based on a standard set back at the start. Even today's Intel x64 processors share much of the same roots as the x86 processors before. Yes, it was impossible to play games made for a 4.7 Mhz processor on a rig with a Pentium (unless you used something like MoSlo, but even then it was spotty), but it could stillrun it.
