Well, sometimes it works, and sometimes it displays the HappyMac/eject/flashing question mark behavior.

Not sure why. It happens between restarts, without physically jostling the machine. It worked, then after a restart, weird behavior.

Anyway... when it works it looks like this:Mac512KeMR2.jpg

The 2M of RAM raises the question of whether it sees the original 512k on the board, because there are (as far as I can tell) six 256k SIMMs. Should read 1536k if it only sees the SIMMs.

Could also be that it automatically sets aside the last 2 SIMM slots for its purported RAM disk ability, and I have six 512k SIMMs in there, but I was pretty sure they were 256ks.

I'll try again with two known 1M SIMMs and see if it shows 2048k or 2560k.
