I was told today from a dealer here in the Chicago area that >these RAM expansion boards will be ready for sale around mid June here. From the discussion on c.s.a.st a while back with Alan Pratt, I believe he said that you can only have 4MB _ST_ ram. You can have 16 MB TTram like you said, but that the other 6MB of ram comes from using the VME bus for ram expansion. In fact, the VME ram is supposed to be faster than STram (no sharing it with video, etc.), even though it is slower than TT ram. However, I wonder why you are limited to only 6MB from the VME? Is it Atari being silly and not allowing you to use _most_ of the '030's addressing capability (of course SOME of it has to be reserved for I/O etc. but not more than 32k worth!) like they did with the ST (you know - the 68k can address 16MB but you are limited to using 4MB max - I mean, even if you dedicated 512k to I/O,ROM,etc. you could put in 15 1/2 MB around it. It would be worth it to use 4-4MB SIMMs as you would only be losing the use of 1/8 of one of the SIMMs (actually 1/16 of two of them)). > >CUL, >Chuck > >P.S.
