Help Identifying Eprom BFFH1277

[Charlescrown]

I am trying to read this eprom without success. I can get the bin from the eprom but I cant find an XDF to view it. I believe it's from a manual VR.

That's for an early VR V6 manual using $12

EDIT: Have you tried the xdf's listed here? viewtopic.php?f=7&t=5

[Charlescrown]

I thought that. Maybe I picked the wrong XDF to try and view it. Thanks I will give the other 2 a go.
Is it 27c256 or 512?

[MAGP]

VR manual should be 256, VR auto is 512 viewtopic.php?f=7&t=655

Still can't read it properly. I downloaded the bin as a 256 and used the only XDF I can find. The one on here is the same as the one in the Memcal ID program but it looks like it's not the right one.

[The1]

can you post the bin?

[Charlescrown]

Hope this works

Looks like I hit a toughie with this one. I only have one XDF for the $12 manual. Maybe it's not that bin file. I might try some others.

This looks like a bad read of a $12. Try cleaning the pins on the eprom. Where you see al lot of 28 in the bin, these are really 00. At location 08 there is a 3A, subtract 28 and you get 12 hex which is the mask ID.

Thanks kojab. I took another read after a bit of wiggling and got what I consider a correct reading.
The good read is attached if anyone is interested.
