Iomega Ditto Max. Yes, it's a piece of shit, but it works enough to make an archival copy and I can restore from a diskette.
Needs ftape 4.x - current kernel is 3.x. This should be a matter of typing "make", but 1) there are a lot of shitty C programmers who are too damn lazy to do ANSI C and who abuse the preprocessor 2) there are a lot of shitty C programmers who have had years to build a decent C/C++ combined environment and have failed. There should be a 1-shot option to make gcc 3.x behave exactly like 2.x (by calling 2.x if necessary).
