ATtiny24/44/84 Adapter for STK500
If you currently have a STK500 development board, you will face a problem because it doesn’t support any of Attiny24/44/84 chips. You have two ways: either buy STK505 adapter which is quite expensive, or develop your own.
Proposed adapter allows ISP and HV programming. It has jumpers (instead of switches as on the '505) to control the dual nature of some of the PORTB pins on the Tiny24 - PB1, PB2, and PB3 are used as the RESET, XTAL1, and XTAL2 connections for this reduced pin-count chip. They can also be used as normal I/O pins if these functions are not needed.
