Title: Anyone remember a SIMM-based hardware project
Post by: ColCon on September 30, 2019, 04:22:50 pm
I seem to remember a SIMM-based hardware project, i think 30 pin, with various plug-in modules other than memory.
Basically a mini back plane processing concept. Anyone know what I'm taking about?

Was it the "Simmstick"?

There are many SOM's out there. Raspberry PI compute module is one example.

My first thought also was the Dontronix module.

When I type in a simple search I get lots of results from multiple manufacturers:

yes there are lot of people trying to promote this sort of idea.   It might be a good idea but there really needs to be a standard.   The Arduino and Raspberry PI form factors have become defacto standards with wide adoption, but I'm not sure anybody leads in the SIMM world.   Sadly the Arduino and PI formats never appeared to be well thought out to me.

Well, I'd expect SIMM designs to be going the way of the dodo, since SIMM memory became obsolete in the mid-1990s. 30-pin SIMM was obsolete by around 1990 and you can't readily get sockets any more. (72-pin SIMM is still available.)

It does make you wonder why anybody would use a function specific card edge connector for a general purpose backplane.   It isn't like the catalogs are not filled with more generic card edge connectors or header type connectors.
