Sort of on this subject, I *really* have troubles with .SDK images.
The main .sdk image is of course Modem MGR, which I have never got
working on my 64K //e.
This is what I do to transfer it to my Apple:
1) Download onto linux box.
2) run nulib 3.25 on the files:
$./nulib xd mmgrfile.sdk [where file = install or whatever]
it creates MMGRFILE.33.SDK (note uppercase).
^^ i am confused at this point as to why it creates an SDK file when it
is supposed to make a .DSK or a .PO file according to rubywands FAQ.
All of the images used are 66K or under, and nulib converts them into
140k files (sounds right to me).
3) Anyhoo, I rename the files to .DSK and:
4) pop them (the 3 dsk files - install, util, program) onto a floppy disk
5) put disk in old dos 486 laptop with serial connection and ADT on it.
adt the disk images over to the apple. That works fine.
6) reboot the apple with the newly created disk. The disks either hang
the system (the floppy continually seeks the disk), or the thing borks
into the monitor.
No clue where to go from here.
Any help as usual to help out a slightly silly feeling individual would
be greatly appreciated.
