Raven060 (luciodra build).

[luciodra]

Congrats on getting to the desktop! That's a pretty good milestone :)

I did much better! Formatting CF and SD with 250 Mb partitions works almost everything!
If now, for example, I have the 2 Gb SD with the 250 Mb primary partition, how do you recommend occupying the rest of the space?
Thank you!

Small satisfactions.

Interesting, I wonder why it's going half speed

If you install the software in here you should be able to get Nova drivers up and running for some colours on that desktop too!

There's some info in raven.txt that might be worth reading.
And then at the boot logo, press delete to enter setup. Go to the nova tab, enable nova checkbox, select the driver for your particular card, and the desired resolution. I'd recommend picking a 256 color mode.

This page can help you identify if you have T0,T3,T4 or T8 variant, or you could just trial-and-error to find what works :)

With the clock at 48.000 I have some stability problems, perhaps due to the 060 or the heat. So I'm using a 24.000 clock that I purchased, so the system is more stable. Doesn't anyone on the forum know where I could buy a heatsink with fan for 060?
The boot menu works quite well, but I have to try it better than at 6.00 in the morning before going to work :D

I have this fan:

Adda AP0512LX-J90. They are available in 5v and 12v. Bought it on aliexpress.
You can use a 12v at 5v for lower noise.
I personality have a 5v and use at 3v.

I think your lc 060 r4 should be ok at 100mhz.
Mine worked ok.
Do you have just black screen at boot?
If yes a cooler will also not help. If it is instability issues at 100 the cooler will probably solve this.

Yes, I also have a black screen at startup, without the Atari logo.
The problem is that it freezes during use and could also depend on the PSU. If the clock is set to 48 (24x2) the Raven has good stability.
The good thing is that progress is daily...
Thank you!

After a few days of testing I can say:

With quartz at 48.00 x2 the system is very unstable
with quartz at 24.00 x2 the system is quite stable
with quartz 48.00 x1 the system is unstable (presents numerous artefacts on the screen).

Since my 060 is a 75 MHz, if I used a 35.00 x2 quartz what results should I expect?

[Oldskool]

My lc is 66 and it runs fine at 100.
I also have a full one which is also stable at 100.
What kind of 68150 do you have and were did you buy it. I had some stability problems with one (33 version) which I bought of Aliexpress.

[luciodra]

My 68150FN40 was also purchased on Aliexpress. Could it be that?
Unfortunately I only have one and I should try to buy another... but are the 68150FN33 also good?

Thank you.

1x is not yet completely implemented as you noticed.

With quartz at 48.00 x2 the system is very unstable
with quartz at 24.00 x2 the system is quite stable

The answer would have to be "don't know" :)
It's probably fine but I'm mostly running 96/48 myself.
I used to test 50/25 quite a bit as well because I like the idea of having some kind recommended / tested configuration for if one has something that isn't happy with the overclock.
Perhaps I should treat 64/32 as that instead of 50/25.. 32mhz is still going to be within spec of the slower 33mhz version 68150, and most 68060's will probably do 64mhz?
(64/32 got me to the desktop last I tried it but I don't think I did any exhaustive tests)
