- ISA is 'Industry Standard Architecture'. It's the 16-bit bus that one
- finds in the typical PC clone. EISA is 'Extended Industry Standard
- Bus'. IT is an extension of the 16-bit ISA to a 32-bit bus-mastering
- bus, which came out in competition to IBM's MCA.

- They hold all the loose bits in the machine together. :-)

- Well, if you have a 'PC' and don't have either ISA, EISA or MCA, then
- you don't have anything connecting all the boards together. If you're
- running DOS, buy the ISA machines. They're cheaper, and you don't
- need the added capacity of the EISA/MCA busses unless you are running
- a multitasking operating system like OS/2 or UNIX.
