Given the lack of information regarding the 486SLC3 would anyone be interested in determining its pinout?
I have an NOS 486SLC3-60 upgrade module that is in perfect condition. I am certain it is indeed a genuine 486SLC3 upgrade module as the stickers attached to it say: FCC ID:ANDIBM486SLC3, IBM FRU: 61G2099, P/N: 61G2093. The processor itself is a QFP-132, it is marked 63G9558. I'm also fairly certain it is actually a 25/75 MHz that is just downclocked.
I would be happy to lend it out to a trustworthy and well established member of the community for the purpose of the pinout being definitively determined so that the information can be made available to the public. I strongly believe in information being available to all. If you're interested, please let me know. I have been wanting to fill this gap in the knowledge of the IBM SLC3 processors for some time.
