It's only >February here :-) Jaycar (Australian electronics chain) faxed me the Cheap PIC Programmer article hot off the press by Oatley Electronics of Sydney (www.oatleyelectronics.com) because it is half the price of the several hundred K81 programmers I have just sold them! The programmer is a copy of the Electronics Now, 9/98 programmer (www.mindspring.com/~covington/noppp). It has no pullup resistors on the data lines, no buffers, uses 1N4148's and requires the beginner who buys it to d/l the complete 9MBytes of MPLAB. Covington clearly had problems as indicated by the two circuit revisions on his website which converted his programmer, in effect, into a 'Tait' programmer. The Editors of both Australian electronics magazines are of the old radio school and clearly not at home with the internet, microcontrollers etc. So they allow asides like the one I mentioned into their final copy. Had they been more familiar with PIC programming and had better advice maybe the deficiencies of the covington design would have been made known to them before publication. regards, Peter ------------------------------------------------- Peter J.
