JTAG is available only in devices with at least 16K of flash.
The newer Tiny device and small megas (i.e. M88) with less
than 16k have the debug wire.
Programmer: You can just get started with a parallel port mode
porogrammer, only 4 resistors. I'm currenlty still using a
AVR910 type programmer which can be driven from Studio or other
packages. Bootloaders are great once you program the bootcode
into your chip.
I use the SP12 programmer which only has two resistors. 8-)
