If you're playing the game at home (which you shouldn't be, because it's a pretty awful game), I now have a slight handle on how the PC-9800 series works. Or at least the first four machines. It's also a lesson in stupidity. #1: PC-9801, 1982 NEC's original 16-bit business machine. Specs wise, you can't complain. Price wise... Jesus Christ. Buying a monitor isn't unexpected, but if you wanted to do anything with this computer, you had to buy a set of 8-inch floppy drives. And want to use word processing software? Go get a kanji ROM board*. So a complete system would set you back about 1 million yen, which is about $10K USD in today's money. No thanks. #2: PC-9801 F, 1983 Make the processor a bit faster, stuff some more useful 5¼-inch drives in the computer itself, and include the kanji ROM board for good measure. Then sell it for less. Suddenly there's a reason to actually buy one of these things. #3: PC-9801 E, 1983 A PC-9801 F with the extras taken out, so you can spend more money in the long run by buying them all separately (except you couldn't straight away, because NEC wouldn't sell you separate 5¼-inch drives at the time). Why would you do this. #4: PC-9801 M, 1984 The disk drives of the F are all well and good, but they're only double density! 640KB per disk (2DD) ?? You want high density (2HD) which brings it up to 1MB. We've also doubled the RAM over the F. Oh by the way these new 2HD drives can't read 2DD disks, so we've broken compatibility with older software. Have fun! ... I'm not kidding about that by the way Got to have F versions and M versions of software because they've split the market. And they didn't solve this problem for years. In fact it would get worse, because the next machine, the PC-9801 U... uses 3½-inch disks! That's at least four different incompatible disk formats for one family of computers (although 8-inch was a dying breed at this point). (p.s. this is Gaplus) *extra fun. So there are thousands of kanji characters, and to make things manageable with the technology of the day, some standards were created and the character set was split up into JIS "levels". So you get the level 1 board for commonly used characters, and if you need the more obscure ones, you get the level 2 board. Both at a cost. But that's just for displaying text on a screen. What if you wanted to print? Apparently the resolution of some printers was too low for kanji and I think(?) some couldn't handle certain JIS levels. So there's another cost for your business - make sure you don't buy the wrong printer.
