*PCE (IBM PC 5150) emulator (IBM PC DOS 1.00 <-- PC Tools 3.24 / IBM PC DOS 3.00 <-- System Speed Test 6.00)
*86box (x86 PC) emulator (IBM PC DOS 3.30 <-- PC Tools 4.11 / IBM PC DOS 3.30 <-- System Speed Test 6.00)
PC-Tools 3.24 runs on IBM PC DOS 1.00/1.10, but the version is recognized as 0.48.
I guess PC-tools 3.24 didn't be supported officially on DOS 1.xx
PC-Tools 4.11 doesn't run on DOS 1.xx (requires DOS 2.x or higher.)
More interesting is that PCE recognizes CPU ID as Intel 8088 correctly, but 86box (or PCEM) recognized CPU ID as NEC V20.
