<DIV><FONT color=#000000 size=2>Folks,</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT> </DIV>
<DIV><FONT color=#000000 size=2>I would appreciate some assistance identifying
the ECM components which I have in my 87 305 TPI TransAm. I am planning on
obtaining a few blank 27C128 or larger (C512 or C1024) EPROM chips and using
them to accept some alternative *.bin data. I will be hunting for a reasonably
priced EPROM programmer, so if anyone has suggestions I would be interested
(I've seen one which does 8Mbit through PC parallel for $129.). I don't mind
putting together something barebones, I'm pretty cheap and handy with an iron if
someone has a suggestion for making one. I'd also like to log the operating
characteristics to a PC through the ALDL. I saw some plans for a MAX232-based
system around, applied to 94-95 Camaros, will it work with my system as well?
Anyways, here goes, a bunch of numbers from all over the place. Any insight to
what they are would be much appreciated:</FONT></DIV>

<DIV><FONT size=2>On the 28-pin EPROM (is this a 27C128?):</FONT></DIV>

cross-reference):</FONT></DIV>

<DIV><FONT size=2>Stickers on ECM harness connectors:</FONT></DIV>
<DIV><FONT size=2>07716500983370048 (newer sticker, says REMAN)</FONT></DIV>
<DIV><FONT size=2>975101200116072 (old sticker, under 2 other layers of
REMAN)</FONT></DIV>

<DIV><FONT size=2>Sticker on metal cover (big, wide, seems to be designed to
identify unit in terms of remanufacturing):</FONT></DIV>
<DIV><FONT size=2>#: 7-7165 (does this indicate it's a 1227165?), </FONT><FONT

size=2>34988, </FONT><FONT size=2>1088-8</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Also, the board has what appears to be a big VOM(?) or
capacitor, and a jumper wire from the 34988 to ground(?). </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I assume most of these numbers are irrelevant. I am most
interested in the EPROM, the other 2 chips, and the style of ECM (165 or
not?)</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Many thanks, and many more to come I think. I'm getting
excited about this stuff, it's been a while. My wife is starting to get
nervous....</FONT></DIV>
