Does anyone have a copy of Bob G8VOI's document "A Beginners Guide to Programming the ATMEL ATtiny 45 and 85"
Nick,
No, a long time since I did that!
I've got quite a few programmed ATT45s, not sure if I have any spare 85s.
Copied below from an old web page, might give some clues but we are talking XP. And LPT for my programmer
I have probably got the files on some old drive, maybe even Bob's PDF but it will take some searching.
Looked on the Wayback Machine but does it save files did not seem to?

REPROGRAMMING See for Bob's definitive guide. For the record the first thread started here:- shows one programmer to reprogram it. My version:- . The software is Windows command line, I used W98, To get it to work on XP or Vista you need to find giveIO.sys on the web (eg but in my case LOADDRV.exe did not work, I got an error message, "invalid service name", I just put giveIO.sys into the same folder as avrpp.exe and avrpp worked properly.
This is a self extracting exe file that puts the individual files in a folder. It still needs installing. Here is just one link that shows how to make a command window easier to use. . Once you have the command prompt in the avrpp folder the command "avrpp file.hex" loads the new file. To set the fuse bits on a new chip use "avrpp -fl11100001" and "avrpp -fh1011101" Thanks Bob! Not necessary for reprogramming one that has already had a prior version of the software Other programmers are available. -ATtiny45/ Removing the fuse from ATTiny45, restores the AVR to be able to use low voltage programmers.
