#189248 - I don't think anyone's that foolish ...
Responding to: Erik Malund's previous message
First of all, you'll play hell installing JTAG on any chip not equipped with the JTAG port. That's still most of 'em, though the number may be shrinking.

Secondly, I don't understand why you keep harping on this feature when the context has clearly eliminated it by virtue of the O/P's statement. He wants to use a device that's in DIL-40 packaging, with no JTAG port, so, as I previously stated, he has few options aside from relying on remote third-party tools, or a MCU-resident monitor.

I did, of course, point out that using that DS89C4x0+MAX232A+11 MHz oscillator would provide him with a development platform more easily than doing it with the DS80C32x series. To do that, he needs neither a programmer, though there's one inherent in the hardware, nor a cross-assembler, once he installs a monitor of his own choosing.

Nobody doubts that it's convenient using JTAG to perform debugging functions. I just have doubts that it's helpful to keep telling the poor guy that he's wrong in choosing the hardware, old or not, that he's chosen to do what he wants. After all, he just wants to play with it.

Since he's playing, there's no point in telling him he's better off playing tiddlywinks when he wants to play pingpong.
