Question A600 and OS 3.9

I'm not sure if this should be in the software forum....but is it possible to run OS3.9 on an A600 and it still be usable? I have an A600 with the trap door ram upgrad and a 4MB SRAM upgrad in the card slot, I also have a good sized hard drive installed too.

Many thanks in advance.

The A600 motherboard only has a 68000, for OS3.9 you need an accelerator with a 68020 or better. And 6 MB Fast-RAM, not 4.

Of course you can Install OS 3.9 with 4MB Fast and 2 MB Chip!
I Did!!!
The only MUST is the accelerator board. You must buy an Apollo 630 (very very rare) or an M-Tec T630 from www.animart.pl
I have an M-Tec 030@42Mhz with an 68882@4aMhz FPU with 4MB Fast RAM and I'm running OS 3.9 pretty good. The only bad thing is that using Genesis with a PCMCIA NIC you only get with 2 MB of free Fast RAM which is pretty low. Other than that everything runs perfect!!!

I have an A500+ with 8MB Fast and an IDE 540MB Hard Disk. I installed OS 3.9 without a problem. Not much difference in speed with the 3.1. Of course with 8 colors glowicons. In many cases, such as hard disk access and "browsing", I find OS 3.9 faster. Of course I do not use the machine for viewing JPEG with a filesize more than 30 MB :-)
As I have not 3.1 ROM I am using the skick345.lha (from aminet).
