You're right, of course, this is a disadvantage if you want to use it more
often than during the setup process to program Flashs. Also, if the device is
installed onto a socket in the 1541-II, it's not possible to install the
drive mech into its original possition anymore. I think it would fit if the
device is not put onto a socket, but soldered into the 1541-II mainboard
directly. But I never tried this, and probably never will. The same problem
exists in the 1571, the power supply sits very close on the mainboard. In
both drives, none of the components that are under the board may be socketed
in this case, and the original ROM must be removed (because it's always in a
socket).

Yes, I will make step-by-step instructions, because it's important to install
the components in the correct sequence, otherwise it might become impossible
to solder some connections.

I usually order Flashs and OTP-EPROMs from www.reichelt.de, they're quite
cheap. I don't buy EPROMs or EEPROMs, because they're too expensive in
comparison, and I can get enough EPROMs for free from old PC mainboards.
If you like, you can also order the parts for the adaptor from me, but
currently I have only the cheap sockets and the DIL adaptors in stock, which
I cannot recommend to beginners, so you'll have to wait for my next order at
Reichelt, which probably will be next year.
