Are you sure about the no-flash models?  That doesn't show up in any
of the networking catalogs I still have (though that predates the
selloff of the networking division, now owned by VNETEK).  They did
show 1 or 2MB FLASH models, and also early 1MB RAM and later 4MB RAM
(for NAS software) but nothing in the 90M without flash boot
capability.

I need to open mine up and see what the flash looks like.  I'm pretty
sure the RAM is just a standard 72 pin parity SIMM.
