I use AIAB
First I transdisk'd my Workbench3 floppies to ADF on the A1200
Then I transrom'd the kickstart 3.1 roms to rom image files.
Then I used NComm3.0 from my AminetSet CDroms on the A1200
connected thru a "LapLink" cable to my Windoze Pee C via serial ports.
I launched Hyperterm on Windoze, configured them both for ZmodemCRC transfers.
Then "uploaded" bbs-style from the A1200 to the Pee C
I obtained anywhere fro 56kbits to 100kbits transfers which equated to about 30 seconds per disk (Im a patient man)
Once the files were on the Pee C , I unconnected,powered-off and placed my A1200 in the closet.
