Summary: Help us oh great and powerful Dr. Dobbs....

Has anyone out there seen any hardware articles onn using the 256 SIMMs
and a little PC board of artful design to upgrade the 128K or 512K
Macs with additional memory. I remember Dr. Dobbs a long time ago
had an article or two on upgrading the thin Macs to 512K could that
circuit be modified to use the 256K SIMMs or are they real exotic
when it comes to addressing or something equally bizarre?

Particularly I would like to take a 128K Mac and 2 x 256K SIMMs and
end up with a 512K (plain vanilla) Mac (E in 512E not necessary).

Thanks
