True IBM PCs (up until the PC-AT, I believe) would also boot into BASIC if the floppy drive was empty and there was no fixed disk. In fact, in early versions of PC-DOS, all the basic command did was bootstrap the ROM BASIC, so it didn’t work on later clones.
- glhaynes 5y agoThe early PS/2 line, at least, would still boot into BASIC, if I remember correctly. I'm fairly certain my Model 70 386 would do so, but I can't remember if I had to disconnect the hard disk or what. Anyway, I definitely remember the Model 25s doing so, but of course they were closer to XTs than they were to "real" PS/2s.
