i just added a herc clone to my 6300. all you have to do is plug in the card and monitor. the herc's screen memory overlaps the 6300's screen memory, but the overlap is all in a 2nd page, which is disabled by default. you can switch between the two using the MSDOS "mode" command. in text mode, the herc looks just like an IBM monochrome display adaptor, so the BIOS routines in your 6300 (and probably every other clone around) will work with it. however, if you have version 1.21 of the 6300 BIOS ROM, scrolling in monochrome mode is pretty buggy. you can order a BIOS upgrade for $35 or use it just for graphics (which most people with 2-monitor systems do). since the stock 6300 video controller has as much resolution as the herc, the only reason to install a herc is to run specific software that supports herc and not the 6300 hi-res mode. by the way, i bought both the board and monitor from a local discount house for $109 total.
