ibm pc rom basic
gwbasic 1.12~3.23, earliest i can find is compaq basic 1.12 named basica.exe included in compaq dos 1.10, renamed to gwbasic since 2.0.
qbasic 1.0~1.1, included in dos5.0~6.22, which not only lacks compiler but also runs as slow as gwbasic, just with a simple editor.
bascom 5.xx, rebranded to ibm bascom 1.0/2.0, quickbasic 1.0 also rumored to be relabled bascom.
quickbasic 2.0~4.5
basic pds 6.0~7.1
vbdos 1.0
thats all i can find, is there anything else?
