The more I dig the more I find wrong

[ghnat]

while taking the motronic a part I noticed something wrong with the eprom... Hmmm. D*mn PO...
Has anyone else found bent pins in their eproms. The pin was not even in its hole, just touching it. Good thing the whole darn thing didn't short out.

I think if you just bend the pins inline with the others you'll be OK. I just put a Steve W. chip in and I could see how someone could bend the pins like that. Need a light touch putting the chip in. Is it a stock or aftermarket chip?

[ghnat]

Gordon,
Stock chip. I had no problem bending it back and popping it back in the board. I just wonder what effect that could have had...

I guess I'll know some day when I get the car back together.

[gost]

PO may have had an aftermarket chip in there and then swapped it out before he sold it. There is not really any reason to remove the chip otherwise. Hope it works fine for you!

If the car ran before you bent the pin back, I would not try to start it now. You will want to identify the chip (27x64, 27x128, 27x256 etc.) because that is probably an address line that is not needed. By bending it back so the pin is inserted the chip will not be addressed correctly and the car will not run. I had a dual map chip installed in a larger eprom at one point and using a switch connected to a pin like that you could select one of two different performance maps. Steve W will be able to guide you further on this.
Good luck -

Thoms, you do not have to worry about that - the car is just about completely disassembled. It will be a LONG time before I can even attempt it.
But I will check and see if the chip is stock or not.

I tend to think the bent pin was more of a mistake, than somebody intentionally bending it out of socket. Just straighten and insert.

Will have NO Effect. I've taken mine out 2 or 3 times, and each time, desoldered and soldered it back in! Pins are bent all kinds of ways. If the solder is good and you have current flow, yer in biz.

You need to contact someone that knows, or find a diagram that shows, the "pinout" of the chip. You may have gotten lucky, and that pin isn't used for anything.

From the photo, I think it is a 24 pin chip. If so, depending on its orientation, it is either A7 (pin 1) or D3 (pin 13).
Poor diagram,

A5 |3 22| A9
A4 |4 21| VPP

A2 |6 19| A10
A1 |7 18| /CE
A0 |8 17| D7

D1 |10 15| D5
D2 |11 14| D4

Would like to know which pin is in question here (for signal's sake).

Easily bent back and reseated...NOT an issue, as long as you don't fracture the connection point at the body...the leads are quite flexive and sturdy.

Was it making a connection in it's seating arrangement (irregardless of what it "looked like")?

Best,

[jetkona]

Nine9six - probably good advise
Kurt - a little reckless
John - a little cautious
Tim - Nice chart
Doyle - "Irregardless" is NOT a word

Greg... Good luck!

[Shadetree930]

The word you are looking for is ... irrespective

This is why I love this forum...beautiful!

[ghnat]

Thanks for the info guys. I am currently in the process of building a rotisserie for my car. A long way to go still!

Irregardless is considered nonstandard because of the two negative elements ir- and -less. It was probably formed on the analogy of such words as irrespective, irrelevant, and irreparable. Those who use it, including on occasion educated speakers, may do so from a desire to add emphasis. Irregardless first appeared in the early 20th century and was perhaps popularized by its use in a comic radio program of the 1930s. Irregardless is a word that many mistakenly believe to be correct usage in formal style, when in fact it is used chiefly in nonstandard speech or casual writing. A combination of irrespective and regardless sometimes used humorously.

..In the dictionary? yes.............used humorously? yes..........

I'll try to be a bit more formal within our our "formal" newsgroup so as not to offend (or confuse?) our formal readers.

I'm so sorry,,,,,,,,,,,,,,,...........hope I didn't offend anyone with it's use. I feel terrible for loving double negatives.............counseling should help.

What are these "chips" of which you speak?

The only "chips" I want in my car are ones with salsa.

[jetkona]

No Offense taked Doyle, just couldn't resist. We do appreciate the linguistics lesson however.

In the future I will happily use the word "Irregardless", irrespective of it's irrelevance and irreparable consequences.

No need for the counseling, we LOVE you just the way you are.

Peace
