Keywords: 6502 code for upper mem Message-ID: <7920@drutx.ATT.COM> Date: 22 Mar 91 21:24:14 GMT Sender: news@drutx.ATT.COM Distribution: comp Lines: 10 I am writing a MIDI SysEx program for the Apple ][+ and //e for use with the Passport MIDI Interface (anyone already have a program that does this by the way?) Anyways, I would like to use the 16K RAM Card in the Apple ][+ for additional memory for storing data, and would like to use the 64K on the Extended 80 Col Card for the APple //e, but don't know how to access it. Does anyone have a 6502 program source that they would be willing to let me take a look at to see how its done?! Any help in this area would greatly ease the pain on my brain!
