In 1985 ACT was renamed "Apricot Computers". By this time, the F1 had become one model in the F Series; other machines in the series were the F1e (a cheaper F1 with less RAM standing at 256KB); the F2 (with two floppy drives) and the F10 (with a 10MB Rodime hard drive, 512KB RAM and a more conventional-looking infra-red keyboard). The Activity GUI was replaced by GEM. The F1e contained a 360KB single sided floppy drive, and the F10 contained a 720KB double sided drive. Some F1e computers shipped with an expansion card that could also be used in the F10, that would modulate the RGB video signal to RF enabling the computer to be used with a domestic television set. This card also contained a composite video output. The machine was unusual in that it contained the same 36-way Centronics parallel port that appeared on many contemporary printers (and continued to do so until virtually replaced with USB and ethernet). This means that a standard 36-way centronics male to centronics male cable needs to be used to connect a printer - and these were hard to find since IBM had introduced the DB25F connector.
