Macintosh LC 630 DOS Compatible

This relatively rare variant of the LC 630 included a DOS card with an Intel 486DX2/66 CPU (some seemingly shipped with Cyrix 486/70). The DOS card could share Mac memory or use its own dedicated RAM.The motherboard has two SIMM sockets, and the DOS daughterboard has a single SIMM socket. (The non-DOS 630 has only one SIMM socket.)
