I tried the link it gave me the usual 404..page not found... but if it is a seri al programmer, the serial port is usually not going to have enough power to prov ide the programming voltage which should be around 13v...serial port is around 1 2v. Also, your computer maybe too fast to do this in which case you should get one of those programs that will slow down your system, run that program first, a nd then run ur programmer software. I have not had success with any of them and gave up and bought a programmer :) but those are the usual problems, and thats what a lot of people are going to tell you to do MikE On Tue, 9 Nov 1999 12:06:46 -0500 Michael Melinosky wrot e: >I was wondering if anybody tried to build the f84 programmer by Jens = >Dyekj=E6r Madsen at http://www.gbar.dtu.dk/~c888600/newpic.htm.
