Hi,
I'm the guy selling the 1230-IV to bob808.
A SIMM of that size won't fit this card. If you look at these pictures I've taken, you'll see you'll need a slimline SIMM so that it doesn't foul the 030 processor - a bit like the 16mb one that I've already got in it:


I've seen people wedge big SIMMs in so that they dont actually clip in but they just sit in the slot, and attach them on with rubber bands, but I couldn't call that a healthy or safe setup. The 030 can get pretty hot when in use, so it needs to be kept clear.
By the way, I've found a new clock battery and it's on its way to me. I'll solder it in as soon as I get it, and make sure it all works and is charged up for you. :-)
Cheers.
