Real Powerloader info...No BS
I actually opened it up tonight. After that April Fools post I got to thinking...
The removable Eprom is a Fairchild NM27C040V
http://www.fairchildsemi.com/pf/FM/FM27C040x120.html
Here is the link for the Specs on the chip and the programmer... Anyone know how to hack this?
http://www.elexp.com/tst_p848.htm
The Model 848 will program this Chip..

Re: Real Powerloader info...No BS (corvette184)
Is it PLCC or DIP?
I have an eprom programmer that will work with it. (No BS, I use it with the chips for my LT1)

Eric I would be glad to send you the Chip and see if you can read it..
Also I wonder if it's erasable? There is no window on the front side..I wonder if the back has the window for UV Erase... :confused:
The rest of the Powerloader is all fully soldered surface mount components. Whick makes be believe even more that all that is need is the ability to write to that chip.

Re: Real Powerloader info...No BS (chuckster)
Chuckster,
In the DIP configuration it would have the UV window on the "top" of the chip, but the PLCC packaging places the UV window on the "bottom". Also, FWIW, the security of this chip is, well... security? :lol:
Not to put too fine a point on it, but with physical access to this chip, it's out bitch. ;)
I've got a loooong history of, umm, bit-banging (among other things) info from eeprom's people didn't want to be poked around in. I don't think whoever designed this PL device really had any major security concerns in mind. Which, could turn into a problem for them.
Ah well...

Re: Real Powerloader info...No BS (chuckster)
I'd be happy to read it for you, but I need to know if its DIP or PLCC. DIP is a rectangular chip with pins on two sides, PLCC is more square and has pins on 4 sides. If its DIP its probably a OTP, one time program.
I dont have the adapter to read/write PLCC on my programmer, but I'll look at getting the adapter I need.
I'd like to have it anyway, since I have a bunch of network cards I'd like to make PXE proms for that are PLCC :)

Re: Real Powerloader info...No BS (66ImpalaLT1)
Eric, it's PLCC (Square)
Let me know I'd be happy to send it...
Also do you have LS1-Edit?
If so maybe you can compare the data from the Chip to the File I backed up from the PCM with the Powerloader code...

The Powerloader was designed to write whatever is on the Chip to the PCM...
If we could put a stock flash on a chip an and get rid of the VIN# check...this could be a great use of old Powerloaders...

Re: Real Powerloader info...No BS (chuckster)
Yeah, I didnt look at the spec sheet too close.
If somebody else already has a PLCC eprom reader I'll let them tackle it. I need a $70 adapter to use PLCC chips in mine. (Not that I wouldnt like to have it)

Re: Real Powerloader info...No BS (66ImpalaLT1)
I have a reader/programmer and UV eraser but I can only do DIP style. I will check and see if I can locate a PLCC adaptor for mine. I deal with programming these things all of the time, but not with the PLCC package.

Re: Real Powerloader info...No BS (MTWallet)
Yep, let us know... :smash: :smash:
We will find afterlife use for these Powerloaders after all.. :D
Even if all we do is a search for the Fan Temps and change them.. At least there is value in that alone.
who knows...Maybe at the least.. just edit the VIN# to the new owners car..
