If you run a PicStart+, I'll suggest getting 2 17C44/JW's as you get a
chance, as the firmware WILL change on you from time to time;  I have
the first /JW in the machine here now, my machine came with 1.50
firmware and I managed to tough it out until the 2.01 firmware arrived;
Next time the firmware updates, I'd need another /JW part.  It'd be nice
if at least *one* came with the machine;  Dream on, huh?  <G>  I'll
probably sell my PS+ off, as with the EMP-10, EMP-20 and Prime-17, I'm
pretty well covered.

Surely you only need 1 JW per programmer?  The original firmware in the OTP is capable of burning 17C44's so as long as you keep the OTP, then there should be no problems...
