Which XDF?

Not sure what that bin is?
I haven't seen any other 808 bins that are 32k, and it doesn't appear to be based of a VR $12 bin either.
Had a look through with a hex editor and didn't come across any company names, copyright info, etc that most custom aftermarket ones have in them either.
It appears to be a real odd ball bin. When viewed with a 2D graph, can make out areas that appear to be tables etc in the first $1000.

Will be interested to see if anybody else can shed some light on what it maybe based off, or whether it is custom code.

Because I couldn't id what chip it was(it looked like white out,then written over) ie.27c128,sst27sf512,etc. I read the chip with several different settings on the willem,so I'll post those up as well.

Can you try reading it as a 27c512

[Doctor Bob]

none of them appear to be valid or good reads.
cant you id the eprom with the programmer?

can you post a picture of the memcal?

the $51 checksum is from$2008 to end it calculates fine?

The car belongs to the older brother of the chap that bought it to me, & he wasn't supposed to have it.I think the word death was used if he took the car,so I don't think I've got much chance of getting another go at the chip.
For future reference, how do I ID a chip with the programmer?

[Doctor Bob]

my programmer has a function to read the id byte of the device & compare it to a database, i use an elnec MemProg2 programmer.
i havent used a willem so i have no idea if it or other "cheapie" programmers have this function

Looks like it is there but doesn't work on my willem anyway
appears it is called romident and their is also a pic of an eprom and Id that is faded out in the software so you can't click it

[v6bucket]

Mine is set up the same way as yours Dec_head.Had a quick look through google & found plenty of leads,just have to find the appropriate info.

[Dec_head]

I just downloaded the latest software and the i.d was highlighted not that it helped i tried it and even without an eprom in the willem it said it was some fujitsu chip same when i put one in.
but as soon as i changed the software settings to a 27c256 it went away

sounds like its not for identifying a type of chip, but rather reading specific manufacturer information out of certain classes of chip
