SE/30 RAM Upgrade
Posted by: jwse30 on 2020-06-18 20:06:47
I have an SE/30 logic board that is giving me fits (another topic for another day) so I swapped in my spare board and all is working fine. Except this board only has 8 meg installed. My other board had 20, and I am thinking of upping this one to at least 20, if not 32. My dilemma is that this board has the plastic SIMM sockets and I am worried that they may snap when I remove and reinstall the SIMMs. Is there anything I can do to make that less likely to happen? My only thought is that if I heat them with a hair dryer (a heat gun may be too much?), thoroughly before trying.

Any tips or suggestions? Thanks in advance,

J White

Personally, I wouldn't worry too much - I've never personally broken a plastic SIMM slot. I've always bent them to the bare minimum that they need to be bent in order to release the SIMM and they've always been intact after.

Oh, they can break. Trust me.

Be very careful. If they do break, if the SIMM on the other side is solid, you can sometime get away with a spacer of cardboard or something else non-conductive to keep the broken one tight. I've even seen someone (maybe here) 3D print little hold-downs for this.

It's done; went from 8 Megs to 32 Megs pretty quick and easy. Oh, except I forgot to put ethernet card back in 🙁

Now it's off to figure out a small RAM disk. Is there a way to have a RAM disk made at startup and then dump the System folder into it and run off of it?

Thanks,

J White
