EmulatorII-list

This was indeed bad news a few months ago... once Julian and I got the EmuComBox finally up and running, the main component was suddenly out of stock and put in backorder everywhere.
Atmel had put the production on hold, and it's unclear if and when production will start up again.

Some other AVR boards can be used too though, although the firmware must slightly be adapted and of course recompiled.

The next-generation EmuComBox, called E-MuSer, is not using the AT90USBKEY anymore; it uses the Teensy board from pjrc.
The Teensy board of the E-MuSer uses an ATMEGA32U4 processor which is not so powerful as the AT90USB1287, but it's fine for the E-Mu high speed RS422 communication requirement. The AT90USB1286 will do the job too, as well as some others (probably the 162 too).

I almost got a heart attack when I heard from PJRC, just after having successfully built the E-MuSer, that their Teensy boards (all variants) were out of stock and that they were having trouble to build new ones due to... production problems at Atmel.

Fortunately PJRC succeeded in getting their hands on another batch of ATMEGAs, so the Teensy can be ordered again. See www.pjrc.com
I will receive a few of them one of the next days; I will also build a few E-MuSers in the coming weeks/months when I have spare time :-)

I still have to write the full "howto build an E-MuSer" document and publish it on the emxp website. This document will be much more detailed than the current EmuComBox document. 
It will contain many photographs of the device from PCB till final product, a step by step explanation of how to build the device and a layout for a compact printboard (not pcb...) (6cm by 6cm) which can hold the full E-MuSer circuitry. 
...this document will be written when I have time left :-)
