Title: OS3.9 requirements
Post by: dougal on March 23, 2012, 08:05:17 PM
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 ran OS3.9 on my A3000 (040 @ 28MHz, 16MB accelerator RAM.) It was noticeably balkier than 3.1, even on RTG. Take that how you will.

I had it running on my 600 with a 25mhz 030 and 32mb RAM. It was a little choppy under strain but it did work.

Ok, so forget it with the 25Mhz 030 and 6MB.

Will wait for the 33Mhz 040 & 16MB. Should run nicely hopefully.

I never really had a RAM issue with it. I think it was just down to the CPU.

Stock 3.9 won't be very pleasant in a 030@25.
If you remove some startup stuff like AmiDock, AsyncWB etc... you can gain lotsa valuable seconds but still I think it won't be very nice.

You can see a small test on ClassicWB 3.9 with some components removed from my old A600 setup here:
http://www.youtube.com/watch?v=8gtDZUm46ks

That video shows it a bit slower than normal because at that point I had a custom ROM kicked that also had USB support for booting USB stick :)
Also don't forget that is using 16 colors that is the MAX for an 640x512 resolution.

Probably with an RTG system, it will be more responsive :)
There is only one way to find out

Yes but soon I will have the 040 33Mhz accelerator... It should run nicely then

It ran decently on my 030/56, but without a graphics card, it just didnt look nice. Ended up ditching it for a 3.1 classic WB pack instead, and that looks a lot nicer :)

You should be able to run OS 3.9 at a reasonable speed due to the PicassoII and RTG. And yes it will run better than an a1200 with same cpu for the same reason!

Actually I should mention it was ClassicWB 3.9 I used :P

I run 3.9 originally on my A2000 GVP060 with Picasso 4 til the gvp died, Was awsome.
Put my GVP030 @ 40Mhz in after that and was not awsome but still real nice.

ClassicWB 3.9 has a lot more add ons and things does it not? So should be slower??

I thought the point of the classicwb packages was to offer the best WB experience on a given machine. They do contain addons but also optimizations to make the system run smoother. Such as an option to free more mem at boot.

Anyway the target system specs are as follows

Quote
ClassicWB OS39

  ECS, 3.1 ROMS, 68020, 6MB RAM, 200MB Hard Drive

  TV/Monitor (Designed for Multisync/Interlaced 640x512)

  GlowIcon System - 16 Colour Screenmode

  Target System - A1200 with accelerator, ROM and memory expansion


I only ever really noticed slowdown on redrawing lots of windows or in folders that contain lots of files. So maybe it's down to the fact i am using ECS and not AGA?

Hmm maybe you are right on ClassicWb..

And yes you are getting redraw slowness due to ECS if you are on A600 chipram is slow.

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.

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:

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.
