The Spectrum machine was introduced by Sinclair Research and I
aquired one sometime during 1983. Until the IBM PC came into use
the Spectrum was of major importance acting as a file server
for loading the various Z80 based Forth systems. The Spectrum also
ran a Z80 Assembler used to produce code modules for the Slave Z80.
The Spectrum has a Technology Research floppy disk interface fitted along
with a 5.25" drive. This transformed the machine, a disk made for reliablity
as well as speed.
