I use PonyProg adapter and software for AT89S micro.

www.lancos.com/prog.html

Adapter described on:
AVR ISP (STK200/300) parallel port interface
Please note that adapter is AT89S compatible.

atmel at89isp cable

Let's Try this one.
You can use this schemetics as reference for making cable for 89S8252 ISP and use with AVRISP software. I'm already made it.

hi drwho78

I build pcb of the sch file of at89isp ,and tested it with @tmel isp software in win xp but IT DOES NOT WORK!

Is there a way to find ISP programmer for atmel at89??
(I saw ramesh reply after building it :( :( )
Regards

I built the cable and tested it. It works with the 89S53, 89LS53, 89LS52, etc. The only change I made to the schematics was replacing the 100 Ohm resistors with 68 Ohm resistors. I found that using 100 Ohm resistors does not work on all PCs. Also, the cable works without the comparator LM393.

The cable was tested with the Atmel software under Windows 98 and 2000. I should work with XP.

89s programmer

:D I'm using the AEC ISP over winXP, so... yes... IT WORKs!
But, it is slower (I suppose that winxp has mor restrictions in the use of the port, and that is the reason)

Hello,

I tried it two times to download the soft Zenner mentioned above from aec-site.
Two times it failed.
If there is anybody able to post this pice (about 60kB) here it would be great.
The filename I mean is aec_isp.zip.

Thanks

Robby
