Hey guys... I'm having difficulties.

I'm trying to create some Apple /// boot disks using MacADT. I have an SE/30 running MacADT, connected to an Apple //c. I format the disk using the //c with the "INIT HELLO" command. I am able to successfuly copy //-series software .dsk files from the SE/30 to the //c using MacADT to ADT transfer.

So I downloaded the Apple3SystemUtils.dsk file from an FTP site, and other system disk files for the Apple ///. I transferred them in the same way to 5.25" floppies using MacADT to ADT (SE/30 to //c). However when I put these disks in the Apple ///, it won't boot. It just gives the error, "I/O Error" in the center of the screen (no other info). When there's no disk in the drive, it just says RETRY ;

Obviously the Apple //c uses a different disk format than the Apple ///. But how else am I supposed to get the SOS disks for Apple /// ???

Someone please help. E-mail or respond here thanks!


PS --

Also I tried something else which didn't work either. I used ProDOS to format the disk. This did not help. (Previously I was using DOS 3.3)

Also I downloaded and made a disk of ADTpro, and while I can run it under ProDOS, I cannot Receive from the SE/30 running MacADT. Though If I'm running DOS 3.3 and plain-old ADT, I can receive from MacADT. Is there a newer version of MacADT than 1.2.1, which would properly talk to ADTpro?

What gives?

Clean the III

Your procedure should work. Apple IIIs are notorious for popping chips up, out of their sockets. I would disassemble the III (taking care to note where all the wires go) and reseat all the chips and connectors. Use a little isopropyl alcohol on a Q-Tip to clean the read/write head on the floppy drive. Fluff up the felt pad that presses the floppy disk to the read/write head.

Most Apple IIIs are 25 years old and have been sitting for 20-15 years in a corner. Give it a little love Smile
