DEC Rainbow 100
This interesting machine used Zilog Z80A and Intel 8088 main processors, allowing it to operate either MS-DOS or CP/M. Introduced in 1983, the 100 had 64K RAM, upgradable to 256K. The 100+ came with 128K, expandable to 896K. The distinctive DEC RX-50 disk drive is thoroughly unforgettable. This example was donated by Mary Christian of Spencer, Massachusetts.
