- I thought so too, and didn't find out this wasn't the case until
- sometime after buying an A2630... :)
-
- Note that the _DKB_ memory will go outside the 9MB space, so the
- solution to 32-bit RAM expansion for A2630 users who have the 9MB
- full already is to use the DKB product.
-
- It's still worth replacing 16-bit RAM with 32-bit RAM (if you have
- it lying around - I also bought another 2MB of 32-bit RAM for the
- A2630, in the expectation that I would be able to add it whenever
- I wanted, plus an A2058 board, for 9MB 16-bit and 4MB 32-bit :(.
- Instead, I've got 7MB 16-bit, 2MB 32-bit, 4MB disabled on the
- A2058, and 2MB of 32-bit RAM in a drawer... :)). Programs running
- in 16-bit RAM are something like 25% of the speed of programs in
- 32-bit RAM (so 32-bit RAM is 4 times better).
