	At last, here's the summary to my questions about the 8-UP:

[	The 8-UP from MicroBotics:  anybody see this beastie?  And more
[importantly, what kind of SIMMs does it need?  Can it use the Mac's 256K SIMMs?

	I've had one response from  Rodger Anderson:

>Yes, I have one.  I am quite pleased with it, but then, what should one
>expect form a memory board?  It does its job just fine.  As far as SIMMS

	The 9 bits are for the PS2 line, no doubt.  I never heard of (or seen)
the "legs" type.  The major difference between Mac SIMMs is the
speed; the Mac+ and SE can use 120ns vs. 100ns for the Mac II.  Often the
120ns SIMMs seem to work fine in the Mac II, but you can never really be sure.

>So, basicly, you should be able to use any SIMMS.

	Sounds to me like it can handle the least common denominator which in
this case is 120ns.

	Sounds good.  If anybody has more info or corrections, feel free to
straighten us out.

Flip side,
