As I say, I'm only aware of using the second parallel port to speed disk
transfers, and in that capacity it's really excellent. If it has other
uses, that's new info to me.. since I never need to copy protected
originals, I've never looked into it.
Once the hardware is in place, open CBM auto-detects the presence of the
parallel connection as an "XP-1541" setup, vs. XM-1541 using only the
serial cable. No further configuration is required, it just reads & writes
at like 4-5X the speed.

The 1541-side parallel port is totally optional, and it is not required
to
produce a working setup.

However, when coupled with an appropriate cable,
drives equipped with the parallel connector operate several times faster
than even the fastest non-parallel setups. That said, any of the X-1541
setups will tend to run a fair bit faster than a genuine Commodre IEC
bus,
so unless you plan to do a +lot+ of transfer,
don't worry about going
the
parallel route.

right? =)
The SD card devices all use Ingo Korb's SD2IEC software, as far as I
know. The main source of documentation I know of is at
<https://www.sd2iec.de/gitweb/?p=sd2iec.git;a=blob;f=README;hb=HEAD>.
