If the device number is 134.21, then you can buy a RCA RCRP05B ($20 at Walgreens or Best Buy) and use setup code TV 1342. Some of the above function codes are already assigned to buttons and are marked with an asterisk below. I've also included some functions (in capital letters) for a U2 model, and these may apply to your projector also. (The U2 mode uses NEC1 24.22, but seems to have some function numbers in common. The RCRP05B can send that 24.21 also, but every function would need to be hand programmed.)
For the functions which aren't already assigned to buttons using TV 1342, assign them using the 994 command, after making sure that you have assigned setup code TV 1342:
1) Press Setup until 2 blinks
2) Enter 994
3) Press setup (2 blinks)
4) Enter an EFC from below table (e.g 00221 for Zoom-)
5) Press the button to assign the function to.
The remote should blink twice.
