A5 and A7 are 27C301 (non-JEDEC), I think A6 and A8 are the same.
 
oK ok ^^


The Eprom correspondence for the others is correct? ?(

Here's something to get you started...
I made this for myself a while back but I find it super useful. I printed it out and have had it stuck to the wall next to my monitor for a couple of years now.

"on disk" is the size of the ROM file as it would be reported by windows
"in MAME" is the size of the ROM file as reported within MAME source

EPROMs within the same color group mean that you can double the ROM file and write it to the next size down the list.

obviously it's not comprehensive but it seems to cover 99% of the stuff I typically need to program.
look in mame and find the file you’re wondering about. Use either this chart in relation to that info, or the size of the file on your disc, and you can validate all these yourself
