Thanks for your note on the Insider and C-Ltd. memory boards. Perhaps you can clear up a confusing set of signals I've received. My dealer, who claims to be an Amiga developer, tells me that a Starboard 2MB board will not give me 2.5MB of memory if installed in a 512K Amiga 1000. He claime the operating system only allows multiples such as 512K, 1MB, 2MB, 4MB, 8MB and that any extra memory will not be loaded into the "free memory map" whatever that is, leaving me with roughly 500K of unusable memory. A call to Commodore "sorta" confirmed this but I'm not informed enough to interpret the explanation. The application I'm interested in is the ability to create longer animations with Aegis Animator and I thought 2.5MB would be better that a 1.5MB internal board which would leave me with about 2MB. Can you shed any light on this?

George – hmmmmm. I have the starboard2 on my 1000 (otherwise 512K) and workbench and FaccII both dutifully record the availability of approx. 2.5 MB of memory. I have not deliberately tried to fill up the ram: disk to see just how close I can come to this number, though. I have had no problems at all with the larger animation demos on this system. @ Anne

There is a location where you get "free" autoconfigure… and possibly he's referring to that, in that a memory board without autoconfig will only partially show up without a little bit of support software. having said that, Dont' worry about it. If you buy a 2mb starboard, you'll have 2.5 mb total. Unless you add more – then you'll _have_ more. If you're doing things that are really memory intensive, then by all means get the biggest ram board you can afford. –Ben–

George, Whoever told you that was wrong. Plain and simple. On my A1000 I had added a 1Meg RAM expansion (Insider) and showed (and used) 1.5Meg of available RAM. Now…the Atari ST only allows RAM to be added in those multiples…was your friend perhaps confused? Don
