Well, the first step could be to take the ROMs out and then check them directly, e.g. wire them up to an Arduino and then read them?Ah. So not so simple. Thanks.
Ah. So not so simple. Thanks.
Thanks. I might look into that. Sounds promising. I'll have to ask for a picture of the board if he will send one.The ROMs should be taken out and checked for corrosion. Perhaps a cleaning may help.
You can burn new ROMs with an adapter an 27C010 Eeproms.
Macintosh SE EEPROM to ROM adapter
So, you have a Mac SE, or you're building up a Mac SE reloaded board using damaged donor that might have bad ROM chips (corroded legs, dead chip etc). Well through the magic of the internet I can bring you this, an adapter that replaces the stock Toshiba TC531000 mask ROMs with any 27C010's...68kmla.org
The ROM on these is on two chips, nothing to do with the hard drive.and then put new ROM on the HD?
To be fair, many people don't have the long torx-15 required to open an SE.
I don't agree. SEs are just as well known to be battery bombed as other models; they often used Maxell batteries and even Vartas can leak. A few bombed SEs have passed through my hands, and I haven't owned many of them.But a SE logic board is often in good condition. I did not see a SE with an exploded battery (like a lot of SE/30s).
