Apple Lisa Video PROM dump

[gruni]

Hello everybody,

in the process of resurrecting an Apple Lisa i am now at the point of inspecting the video prom. Does anybody have a dump of said rom chip that i can compare my image to?

Thanks in advance

I haven't looked too closely at these, but check here? http://bitsavers.informatik.uni-stuttgart.de/bits/Apple/Lisa/firmware/video/

Also, as you may already know, your Lisa's serial number is kept in the ROM, so you will notice at least some differences from whatever's in that directory.

Thank you so much! Looks like my ROM is okay. I noticed a stuck LSB in my DUMP, i will have to figure out if it is a problem in the chip or if the connection to my reader using jumper wires was bad...
