Re: MCA PowerPC (250/41t) Documentation Scanned

Oh definitely, your site's been a great resource for getting my RS/6000s 
working. One thing I'd mention too about the MCA machines is that if you 
get an MCA machine, you should dump or at the very least backup the 
EPROMs. The EPROM chips will eventually go bad and they also contain the 
machine serial number. I know for a fact at least a few RS6ks have died 
for this reason. These are usually on the CPU board or motherboard/planar.

On a related note, the Ardent Tool of Capitalism database actually has 
MCA RS/6000 information as well including motherboard layouts with 
listings of each component (for most models).
