Sorry for resurrecting this old thread, but I am looking to do the same upgrade, from 4 MB to 8 MB on my Viper 630.

These chips seem very hard to find, compatible ones present on 8 MB simms are all 70ns, while this accelerator requires 60ns at least. EDO SIMMs do have compatible versions at 60ns but will EDO ram work on this accelerator? Especially in conjunction with 2 fast page chips already installed? Can anyone shed some light on this?

Last but not least, please note for those looking to do this upgrade, it will disable the PCMCIA port under Kickstart 3.1, which is a terrible idea on the A600. The designers, in their infinite wisdom chose to map it in the Z-II area despite using a full 68030.

So I will be trying to use a software patch posted in another thread here to bypass this obstacle.
