Emax

The labelling/coding system of these ICs can evolve in time, that's why I only mentioned the basic "root" identifier of the RS422 ICs.
But since the EmuSer uses DIP packages, the UA9638CP and UA9637ACP can certainly be used; FYI these are the ones that I always use when I build EmuSers.

If you intend to use the EmuSer primarily for transferring complete BANKS between a PC and the Emax/Emax-II, you should consider using SCSI drives attached to the Emax instead of using the EmuSer. Transferring banks through RS422 takes between 30 and 40 seconds; SCSI is much faster. Moreover, if you are using an Emax-II, the banks can only be transferred from PC to Emax-II through RS422 (not the other way around) and the bank should be a 512K compressed bank (so not e.g. a 16 bit 2MB bank). Both restrictions are imposed by the Emax-II operating system, not by the EmuSer or EMXP.

However, if you intend to use the EmuSer for transferring individual samples (WAV files), it can be an attractive alternative for MIDI, because it's much faster.
