Question, I want to backup the eproms from some HP equipment I have.
I think I write all the data onto a CD, maybe I also reprogram then right away.
some time ago I bought a dataman eprom programmer with the corresponding ISA card.
This is the first time I work with eproms but luckely the software for the programmer is very easy to use and supports a lot of old eprom types.
I also read about eraser light intensity, the time it takes to erase a eprom can be found in a datasheet.
For so far I think I will suceed in doing the job.
Can someone with some experience tell me how I know the data is read properly?
How do I know I erased the device properly? Should I read out the device again and open some kind of file to see if all data is gone?
I have read on the internet bits of data can retiurn after a too short exposure of UV, should I left the device for a day before checking it?
