Re: Trying to run SD for EII on a New MacBook Pro 17" 2.4 ghz

2010-03-24 by esynthesist

Well I have currently the "expensive" prototype USB/RS422 device which is working fine for a few months already with both my EII and Emax :)
By the way: "expensive" means about USD 50... But hey, the new one will even be cheaper and smaller and easier to assemble so that  sounds really great !
Note: in the meanwhile EMXP v2.08 is ready for use with USB/RS422, but it will only be released once I receive the confirmation "from Australia" that the new device is ready and schematics are published :)

It would not work because the adapter could not provide as high as a 1MHz signal to the MIDI interface. It did, however, work with a 56K modem that needed a lot less than 1Mhz.

The "Yosemite" Blue & White G3, and the "Yikes" G4 are the only two machines that accept this adapter, and thus are the two most modern Macs that I am aware of that in theory can communicate directly with the Emulator II.
