I have such a clone: I bought a PC motherboard in 1986 and built a PC
clone around that.  It had only a ROM BIOS, but it had sockets for ROM
BASIC as well.  Later, I read the ROM contents off an IBM PC, burnt my
own ROM's and put them in the ROM sockets of my clone.  I even
replaced the ROM BIOS with an IBM PC ROM BIOS.  It worked fine!
