Industrial Micro Systems - 4 Line Communications
IMS made a number of Z80 CPU boards of increasing degrees of
complexity and sophistication. The 4800 was their last board. It was an
intensely packed S-100 board
Around 1982 IMS change their name to
Intercontinental Micro Systems and came up with extremely
boards. The CPZ-4800 had a 4MHz Z80 CPU, a
single and double density floppy disk controller (WD 1793) for 8" or 5"
drives, two serial ports, two parallel ports, 64K of dynamic RAM on board,
memory addressing/management for IEEE 696 16Mg of memory, vector interrupt

had come a long way!
