|  plus/4 Emulator
I find that Minus/4 for DOS works great on a Pentium (One) system if booted to DOS. Depending on what version of Windows you're running, you may or may not easily be able to do this.
Minus/4 for Windows, or the DOS version when running under a DOS box within Windows, tend to give me double characters ("DDIIRREECCTTOORRYY"). I suspect this is because the timing loop for reading the keyboard is optimized for Europe (50 cycles/second AC) as opposed to North America (60 cycles/sec.).
Other emulators I've tried tend to run slow on my AMD K6-2/300 MHz/PC100 bus. Ironically, my K6-266/PC66 bus runs Minus/4 for DOS a bit faster than my 300 does.
Minus/4 comes complete with all ROM images it needs in the download ZIPfile. It supports the D64 format (T64 doesn't work yet) and includes the built-in 3-Plus-1 software as well.
