Identify the main ISA signal lines and how they are used to transfer data. Answer clearly the following: (a) The main differences between a PC card and an ISA card. (b) How the byte enable lines are used. (c) How is a read or write transfer identified? (d) How is a memory read/write or isolated memory read/write transfer identified? (e) The interrupt lines which are available on a PC card and an ISA card. Typically what devices could be supported by a PC card (that is, what devices use the interrupts that a PC card can support). How does this related to the original specification of the PC?
