Launched in 1975, the IMSAI 8080 was an early microcomputer built around Intel’s 8080 and 8085 microprocessors.
According to Wikipedia, memory options included 256/4K bytes on a 4K board (static), along with 16K, 32K and 64K DRAM configurations. In terms of storage, the IMSAI supported a cassette drive, floppy disks (5 1⁄4 & 8″) and hard drives (CDC Hawk-5 MB fixed, 5 MB removable).
