Ethernet reliability
NET support is by no means flawless. It works for some people, and not
for others. Ethernet support has been introduced in firmware 1.5, so it
might (not) work (reliably) for your setup.
IEC Bus hangs
As with real drives the C64 will appear to hang when drive commands are
issued and the initialization sequence of drives have not been completed
yet. Be sure to wait long enough to let the drives power up correctly.
When the drive does not respond to loading files, but does display
directories, you might be using the wrong cartridge firmware
(PAL/NTSC).
