Buy or build one. We will be using the reset pin for ADC or I/O as
well. I know for sure that the core cannot block reset in software
and low voltage ISP needs it to work. So, only HV prog. can work.

I've been reading the tiny13 data*** for hours, and it keeps
mentioning DIEOE,DIEOV etc to change the port function.

These are internal bits explained on figure 24. They are not softwware
accessible.

For using the reset pin for something else then reset you MUST burn the
fuse, and you MUST have a HV programmer for reprogramming.

I'll never understand why people hesitate buying proper tools. The STK500 is
just 80?.

Hi,
I was just trying to replace a 555 with an AVR controlled by a 89s52
for more flexibility, and was utterly confused by the documentation,
which would not have been resolved by having "proper tools".

I did get a proper tool once , the Atmel 89s51 programmer, the
software crashes about 3 times a day

And it is great if you can build proper tools yourself, which is
essential with the spanish postal system.

My AVR programmer, with Lancos/ponyprog software is less than a 0.50
Euro, absolutely perfect for my needs, I put it on the final PCB's
