sam hardware:
The SAM Coupe is a modern micro-computer using a Z80B microprocessor running at 6MHz. It has 256K RAM as standard, with an expansion socket to allow the memory to be doubled to 512K with a small expansion board.
The machine's main controller is a VLSI VGT-200 gate array (ASIC), customised to carry out the main tasks of processor/video contention, paging and management of all memory, video memory mapping, colour
palette table allocation, and all input/output port control. There are four modes of video operation with a hardware capacity to show 16 colours from a palette of 128 on each screen line.
The sound for the machine is generated by a Philips SAA1099, with a capability in stereo of six channels over eight octaves with 256 tones per octave, two white noise generators, six amplitude controllers and
two envelope wave shapers. GENERAL SPECIFICATIONS:CPU Z80B microprocessor running at 6MHz
