History
When the Z88 came out there was no internet or standard for communicating between different computers.
...
Cambridge Computer bought out 2 versions for the PC. PC Link used the Imp-Exp protocol. PC Link II ran as an application supplied on a 32K EPROM card and as a DOS program on the PC. It introduced new commands that enabled all commands to be controlled from the PC. PipeDream to WordStar and PipeDream to Lotus 1-2-3 file conversion was supplied. .
Ranger came up with a different approach. They had already produced Ranger Disk and had written the software to run on the Z88. Just a few tweaks were needed on the Z88 and a small DOS program to make the PC look like a Ranger disk and they were off. As their program ran outside of OZ, they controlled the serial port directly, enabling faster transfer speeds to be realised.
There was no reason why this small program was not developed for other computers i.e. Apple Mac, but this was not to be.
How do they all stack up?
