][2Mac is a set of 2 applications, 1 for the Mac and 1 for the Apple-][, which allows you to backup Apple-][ DOS 3.3-, CHE-DOS 3.4- and Pro-DOS-floppies to a Mac in a format that is recognized by IIe, the Apple //e emulator for the Mac, written by Victor and Vincent Tan.
][2Mac should be run under the DOS 3.3 or CHE-DOS 3.4 Operating System.
The Apple-][ program, written in Applesoft Basic, expects a CCS-7710 (compatible) serial interface, running at 9600 bps, in slot #2 by default. If a different interface is being used or a different slot or speed, then it should not be difficult to change that. Below you will find a list of all supported interfacecards.
The floppy-images are passed from the Apple-][ to the Mac over a serial cable . A 35 track floppy will take just a few minutes to get transferred at 9600 bps.
Here is how it works:
Apple-][:
Type in: IN#x (where x is the slot# you have put your serial card in)
Mac:
Under the 'Special' menu select the kind of Apple-][ (interface) you are going to use. Transmissionspeed is 300 bps for the Apple-//c and other Apple-][-types equipped with an Apple Communications Interface Card. Otherwise the speed defaults to 9600 bps.
Under the 'File' menu select 'Download BASIC-program to Apple-]['
The Mac will now start to download the Basic-program to the Apple-][. When the download is done change line 20 of the Basic-program and fill in as much as you know about your configuration.
The more data you can supply the easier it will be for the Basic-program to find out exactly how to send out the floppies to the Mac!
When line 20 in the BASIC-program seems to be OK then I suggest you save the program as it is now. Then proceed as follows:
Apple-][:
Type in: RUN
Mac:
Under the 'File' menu select 'Receive Apple-][ disk' and define a name for the resulting file
Apple-][:
Answer the questions about slot- and drivenumber where the floppy-to-be-transferred can be found
If the Apple-][ program fails, the reason will probably be one or more wrong definitions in line 20 of the Applesoft program. This could be the case because you are using an unsupported interface...
If you seem to be unable to get the transfer going then sit down behind the Apple-][ and type:
CALL -151
Cx00L (where x is the slot# the card is in)
L
L (keep hitting L until you reach CxFF)
L
while typing the L commands look for data that says like:
LDA $C080,X
. .
. .
or: STA $C081,X
. .
. .
or maybe: LDA $C0A0
. .
. .
or: STA $C0A1
. .
. .
Let me know what you see there...
Also tell me if one of the bigger chips on the interface carries stamped
data that contains the number 6850 (like MC6850) or 6551 or not...
Wait for my replies (I WILL GET BACK TO YOU!)....

12-aug-1996, v0.9b1, first beta-release
About the Apple //e emulator:
I myself discovered the emulator at sumex-aim.stanford.edu under the name
/info-mac/app/IIe-301.hqx.
The emulator can also be downloaded from Vincent Tan's internet-web-site using the URL: http://www.usyd.edu.au/~vtan/index.html
