Wait a second... Amiga, ddid I hear you correctly? Did you say that this wonderful 512K to 8 meg system Can't Give Out MORE THAN 32K AT A TIME? <FLAME ON> WHAT IS THIS? Aren't you aware that this is STUPID? HAven't you seen the troubles people have with 64K segment pc's? (no brand mentioned, but you should know). And now you limit it to 32 Bleeping Kay? <Flame off> My biggest complaint with the 8088 series is that it is too limited by the 64K segment stuff. Now, you are doing what? What happens if my program is larger than 32K? What happens if I am using a large data structure? (Or even a moderate one, say 30 byte records and an array of 1000 records?) THIS MUST GO!!! I don't care what you do internally, but a user must be able to request an arbitrary amount of memory and have it returned to them if possible. PLEASE get this fixed in 1.1. Pretty please. (And how about putting an 8 bit adder and comparator into an optional expansion board? Please put two comparators--the adder is BASE, the comparators MIN and MAX. If they say 'overflow', the program needs to terminate.) Michael Gersten p.s. Disclaimer goes here.

I've fought the Intel chip 64K follies for too many hours. You Sun-using developers have gotta be sensitive to the frustrations of those of us who are intolerant of 16 bit technologies like the 808x's. Don't do this to us!

Well, unless I have a very strange Amiga, there is no WAY this is true. I have made requests to malloc in excess of 128,000 bytes, and the system has never burped. Also, if you look at the program FRAGS on the Lattice C disk, you will see that at times chunks in excess of 210K are available. There is no reason to segment a totally unsegmented architecture. Any segmentation in the Amiga would just be arbitrarily assigned by the people who wrote Intuition. Robert French French#Robert%d@LLL-MFE.ARPA

of the Amiga and need good documentation on memory expansion. This would includeschematics, timing of the bus and the bus rate, the uses of the pins on the memory expansion slot, etc... Any good source (besides the Hardware Ref Manual, which I have) recommended?

Any good source (besides the Hardware Ref >Manual, which I have) recommended? The memory expansion connector on the front of the machine is essentially limited to adding the other 256K of chip memory. It has the signals needed to do this much and no more. The expansion connector on the side of the machine is much more flexible (take that Atari!) and is documented in the Expansion Architure Document availabe from Commodore. --------------------------------------- SUPPORT SERVICES Due to finite resources, we are forced to restrict some of our support services.
