[sdiy] Need general advice for a uP

[Larry]

The August 2001 issues of Nuts & Volts magazine (www.nutsvolts.com) had an 
article on the AVR's.  It included construction details for In-Circuit 
programmers for 8, 20, and 40 pin AVR chips.  They even have a picture of 
an 8051 being updated to an AVR8515!  You might want to check it out.  I 
just got a subscription, and for those with an interest in PIC's, Stamps, 
and AVR's, this magazine has a lot of good data (articles, suppliers, ...).
