Does anyone know if that board has any undocumented $options for adding memory beyond 1M without displacing the 44256s? Hmm ... either you have a more recent version of the Suntac motherboard than I do, or the use of 44256s is an undocumented option in the revision of the motherboard manual that I got (not that it's much of a manual anyway ... the english is awful and it looks like it was produced in about 15 minutes). The options for my board are: 512K 18 x 41256 640K 18 x 41256 + 18 x 4164 1M 36 x 41256 2M 18 x 511000 4M 36 x 511000 So when I upgraded from 640K to 1M, I had to swallow those 4164s (not that they're worth much anyway) ... what I'm not looking forward to is the 36 41256s I'll have to swallow if I upgrade beyond 1M before buying a new machine. -- Stephen M.
