Hello :-D
Finally got the *cough* (sensored) to post stuff here, been an amigan for ages (still supporting them) but i'm now a pc techie :-(
Anyways, CrossDos usually resides in your Storage/DosDrivers directory on SYS (Workbench partition), if not, you can probably find them on your Workbench 3.0 diskettes, usually the "STORAGE 3.0" disk... Limitation is that it can only write 720kb per disk, a solution is to use lha to archive the files on the pc, and span them across a few disks; then extract them on the amiga, and re-join the files into one chunk (pain in the arse)
Anys, your parallel lead... (better solution) Only limitation you'll find with the parallel tranfer lead is the length, I think its about 3 metres before it starts behaving erratically, but transfer rates shoot up to about 115.2k/s. I have some cable schematics I used that worked great with PC2Amiga a few years back (PC2AM*.lha on Aminet) but it involves a fair bit of DIY work. Also have mods for standard Parallel laplink cables; but most come pre-moulded, and are easily damaged when you try to hack your way into the connectors :-P
I can get some to yer if you live around AU, if not... well then, email me if you want the schematics, they may be included with the current version of PC2AM, but yer.
I'm done now
