WarpEngine 68060 @80mhz!

[fitzsteve]

I think the clock on 040 cards is 2x (i.e 80mhz for 40mhz) 50mhz for 25mhz, etc.

Going back a few posts, are we saying you have to disable the FPU to use this, I imagine that would cripple performance?

 

[SpeedGeek]

The 040 requires 2 CLKs: A 1x BCLK and a 2x PCLK. This adapter runs the 060 from PCLK and uses BCLK as a CLK Enable to gate the 060s bus controller on external cycles.

The FPU is disabled only for early startup and then enabled by 68060.library at boot time.

ah,that explains the phase five libs.

Awesome!

I've been looking around lately to find some kind of 040 to 060 adaptor, and the only source I found was "overpriced". So this solution is good to see! Let's hope it becomes publicly available!

With all the hackery/developments in the Amiga scene over the last few years, I really don't think the Amiga has ever had it so damn good!

What about a MACH130 Apollo 1240 board?
I guess there is no need of a voltage adapter on the board itself, but would i need to change the MACH and the ROM?

Totally agree - it is inspiring really

Many thanks to my good friend SuperCosmos (and thanks to matthey also) for the 060 adapter and Rev. 1 CPU!!!

After many hours of work (and some hair pulling, head scratching and saying a few 4 letter words) I finally got the adapter working!

First, was the hardware fix (getting my A3640 back to 25 MHz) and that was the relatively easy part. Then adding the PCLK skew compensation mod (again relatively easy).

Next, building a new Kickstart ROM compatible with the 060. Should have been relatively easy but very difficult due to some corrupt files in my Remus build directory. (Also, complicated a bit by the 2 separate 040 and 060 exec.library's needed).

Anyway, the end result is in A3660.png (for you curiosity seekers).

Awesome work! Any pictures of the adapter itself?

 

[fitzsteve]

Sweet, now we just want to see these in poduction

 

[stachu100]

Count me for 5 pcs too!

 

[baderman]

Fantastic work!

 

[cugar124]

I now begin to cry sold mine ahhhhhhhhhh. Awesome work just wondering would this work on a 1240 Apollo might be stupid but hey I am the man to ask stupid stuff LOL

See stupid I should have checked the rest of the thread someone else has asked already!!!

count me in for one if they work with a Mach130 Apollo 1240

@protek
There is already plenty of hardware prOn on the A1k.org thread!

@fitzsteve & @stachu
I'm not selling these adapters, this was a gift from my generous friend in France!

@baderman
Thanks, but Mozart designed the adapter and Cosmos patched exec.library so it could work without building a Zorro2 PCB so I must give credit where it's due.

@cugar124
It could work with your Apollo 1240 but you may need a skew compensation mod if it uses a clock divider to generate BCLK/PCLK. (The adapter was designed for a clock doubler PLL which already provides the skew compensation).

P.S. I now have a patched exec.library (45.20b) working with 030, 040 and 060! I'm sending it to Cosmos for additional beta testing...

OK, as promised (to my friend in France) the first episode of A3660 overclocking has begun!

I attached a small cooling fan to the Rev. 1 CPU + Ramsey's CLK90 is modified for the A3000*.

Hopefully, as I acquire the additional components needed and time permitting clock speeds will increase with future episodes.

*Note: There is no practical overclocking limit with the adapter itself.

 

[protek]

The public demands to see the red performance bar!

Looks very nice!

 

[qq1975b]

Does anybody know if this A3660 mod is going to be developed (and sold)? In A1K I suppose....

Thank you

 

[protek]

Well, according to SpeedGeek over at EAB, it is really a DIY project. I guess we needed someone who's ordered batches of PCBs to gather a list of interested people and organize an order based on the schematics.

Anyone game?

 

[qq1975b]

Sure there are some people interested in upgrading their A3640 to an A3660. Is the most common accelerator on A4000 and the productivity improvement is quite important from a 68040@25 to a 68060@50. It would be useful to know the ratio of improvement in MIPS and MFLOPS: 4 times maybe?
Let's hope that someone with experience that is interested in having some for his A4000s is interested in doing this to achieve a lower cost per board. I will take a look on EAB to follow it.

Sure I am interested in having them but I have 0 experience

 

[storhemulen]

I would love to upgrade both my A3000 and A4000 with 060!
