OS3.9 requirements

[dougal]

Ok OS 3.9 is installed

It runs very well actually even with 25Mhz 030 and only 6MB fast ram and 1MB chipram.

I'm surprised... And i'm at 800x600 16bit colors (64,000 colors ?)

The only thing i cannot do is load the backdrops, most likely because of the very low fast memory. That should all be solved once i get the Geforce 040 with 16mb of its own 32 bit ram.

You might consider Happy Env to save memory. AmigaOS 3.9 puts lots of stuff in ENV: and Happy Env allows them to stay on the hard drive instead.

Just did... Thats pretty good actually. Thanks

Currently I run OS 3.9 on my A1200 040 & 64MB and it works great.

I'd like to install it on my A2000 as that has a Picasso II and I imagine it would look and run great.

Would it run nicely with 030 @ 25Mhz and 6MB Ram + Picasso II ?

My GVP GeForce 040 @ 33Mhz with 16MB 32bit ram should arrive in a couple of days. How would it run with the 040 + 16MB 32 bit ram + 6MB 24 bit ram and Picasso II ?

Would it run even better in some aspects than it does on the A1200 ?

I have a A2000 with the same GVP 040 @ 33Mhz Geforce and Picasso II but with Megachip.  It runs fine, simular to my A4000d.  Only diff is that screen and windows/icons render slower.  Opening Prefs also shows that the SCSI throughput of the Geforce is slower than a High speed CF Card on A4000D IDE.

It's quite usable but you will notice the difference from your A1200. Especially if your A1200 has a high speed CF Card.

Using HappyEnv will save you memory but will slow down the machine further.

Never used Happy ENV but if it takes ENV stuff out of RAM that means it must load it from HD so slower by default.

That's pretty slow SCSI. It might be time for a GuruROM. Peter Keunecke's icon.library should help with icon speed:

Using HappyEnv will save you memory but will slow down the machine further.

I don't notice any slow down here but I get 30MB/s on my CSMK3 hard drive . There shouldn't be much overhead the way HappyEnv is implemented (file system) but variables are read from the hard driver the first time they are accessed. Booting is generally faster though as all the variables are not copied from hard drive to ram on startup.

I made a small video just messing about with OS 3.9. Its not THAT bad with the 25 Mhz 030 and only 6mb fast and 1mb chip.  Running at 16bit colors (65,000?) and 800x600. It has eaten a lot of my fastram but oh well.

Enjoy

I told you it would be fun and usable

Nice vid man but you have to get rid of the borders on those new icons..

To save RAM, you could run it in 256 colors.  Workbench will look the same.  And don't use a screen or window backdrop.

Depends. RAM speed about 20 MB/s, CSPPC SCSI speed about 30 MB/s with my gear.
