Limp home mode

[Bob Wooten]

Ludis,

thanks for all the information (on LHM & the RESET line).  I was working on
it last night & it seems that somehow I killed the ECM.  I am not sure what
I did & I am going to dig a bit deeper tomorrow night (not in the right
frame of mind tonight, tonight it would be hammer tomorrow maybe tweaker).
@ some point I killed the battery so I had to put the charger on it.  I
tried to get the lapdog to talk with it & no go, so I put the original prom
into it (the baseline) & nothing.

on the bright side I found the open wire that was preventing the CEL to come
on, only now it is on ALL the time.  I am not much into the smiley face in
emails thing but I have a big :( going on here tonight.

I guess that I can flip the inverse attitude (~attitude?) & look @ this as a
LHM learning experience.  although I wanted this to be an emulator
experience & to take the LHM class later in the semester.

anywho, I will talk @ yall tomorrow, I hear a Guinness calling my name.  I
am not sure what is goin on with my email.  I think that Earthlink is on
crack or something.  I got 54 emails tonight & they are mostly from the 6th
& 7th.  I have it set up to delete from the server but??????? & they were
not here last night.  not sure.

Tanx amigo

than anything i suppose).

Pin 2 turns two of the 5V outputs on and off.  The third 5V output is
always on.  Some of the RC nets might control the duration of the RESET.
 Some are probably for current limiting of the outputs.

Yes.


BTW, _what_ did you do to your message?  I couldn't get it to be
automatically quoted.  I had to copy/paste your text above.
