Very early machines included the OS on a floppy disk, but this was
quickly replaced with ROM versions instead. Another early addition
(after about 6 months) was an RF Modulator that allowed the machine
to be hooked to a colour TV when run in it low resolution mode.
These models were known as the 520 STm, although the m did not
appear on the label. |
