The Aleph1 486PC (Elvis) Expansion card (revision 2) was the third generation of Aleph1 PC Expansion cards. It provided a complete PC on a podule card complete with up to 16MB RAM and an optional 387 FPU. The 486PC Expansion card has a Cyrix 486SLC2 and a 2, 4, 8 or 16 MB SIMM. Unlike the previous generations the Elvis cards has and IDE interface for direct connection of a PC IDE hard disc. It has its own serial and parallel ports (see picture of back). The PC Expansion card enabled an Archimedes to run MSDOS or Windows 3.1 in a RISC OS window.
