Unbricking Ls1 Based PCM"S

[commodorenut]

Ok guys i have a few bricked pcm's here that were given to me.

I would like to bring them back to life.

Can i get a good pcm and read the intel flash chip which i think its a 28F400BX with a 44pin Soic Clip.

Then write it on the bad Flash chip??

[Dylan]

Yes you can

[Dylan]

I have recovered a few without removing the flash chip.

[commodorenut]

Yes you can

Thanx Dylan

I was hoping i didnt have to remove the flash chip

[commodorenut]

I have recovered a few without removing the flash chip.

Did you used a soic clip or solder wires?

[Dylan]

I have software that isn't commercial. It doesn't always recover.
If it needs the flash chip removed I sender to another guy who can do it quick and very reasonably priced.

[Dylan]

Mcumall make a great DSOP adaptor for around $40US and the actual flash chips are quite cheap too. If you brought an adaptor a few spare flash chips wouldn't hurt.

[commodorenut]

I have plenty of Soic clips and plenty of programmers here,
Might give it a go on the weekend.

Was just curious if i had to remove the chip or not
