I see 4 SDRAM on the replay expansion board v1.0

4 SDRAM = How many Mb ??

Hum... It's not enough... With faster 060 (about 100 Mhz), software will be more complicated and will need more ram !

Add 384 Mb, Yaqube ! SDRAM in China is cheap these days...

Users don't want slowdown with HD partition swap...


The Natami team should add 512 Mo of fastram too on the Natami...

>I think 128MB is fine for now until we actually see some applications being produced that require more, or at least slots that can be added to later

For now, yes !

But when you develop a product, you MUST think about the future...

Faster CPU = bigger software = more fastram needed !


1 module 32 Mb SDRAM 5 ns is less than 4 USD today : users will be ok to add some money to get more fastram, I'm sure. Open a poll to check...

>My "real" Amiga never had more than 13MB, and I was never pressed for space

Because you have a CPU not very powerfull !


>I think 128MB will be fine for now, it could take a very long time for someone to write some 68k AGA code that would require more than 128mb to run (eg FPGA specific code)

128 Mb or 256 Mb will be not enough soon too : remember the A500. At the begining 512 Kb was enough for most of the games/demos. But quickly, 1 Mb was required...

512 Mb only on the Natami = big mistake...


@mikej & @yaqube

It's your product, do what you wants ! I'm only writting here what I mean.

Remember well that SDRam is old now and not used very much on the market these days.
Brokers in China perfectly know that and have only one goal : sell. So, you can discuss and purchase one 32 Mb module at 1.50~2.00 USD I'm sure...
