Upgrading Apollo 4040 to 4060...

I have no evidence either way. bb_neo earlier in this thread said he could not get his Apollo 4060 to work and it had 3 * MACH130 chips. Could be a coincidence?

However I do know that Apollo 1240's with mach130 chips have been upgraded successfully to 1260's.

No. The only file I have is the one you used.

I tried in many other ways but it doesn't works... black screen, no boot...
Then I need to assume that apollo 4040 with 3 * mach130 cannot be upgraded to 4060?

need I to swap byte on that before burn?

I would first assume you screwed up. The soldering of the new pins, the crystal, the regulator board, the jumpers etc. etc. Once you have eliminated all of those.... maybe...

Does it still work as a 4040?

No idea. Try it?

My apollo already have cpu socket with all pins for the 68060 and socketed crystal... I built the regulator board as Dimlow and works fine, the jumpers are in correct position... all going to the right way!

The card still works as a 4040, but doesn't works as 4060

maybe the eproms? I tried two different bin files but nothing, the sreen remain black and no boot...

I used MC68060RC50 and 50Mhz crystal

Then I'm not yet screwed up

Maybe the MC68060RC50 is broken? anybody wants to test it for me? I can ship it anywere in europe...

I m really pissed. I paid my "new" 060 CPU Rev 6 70€ and now the board isn't working ! I was so careful doing the modifications I can't believe that it doesn't work. There must be something to do.

I am not ready to send it to France (for repair), yet. No more money!

alexh, do you have the same board? I know Chain has one because he even overlocked it to 100Mhz. Do you know someone here in eab you trust, has excellent knowledge in electronics, has the same board to compare the mesures and of course has time and wishes to help me...
I could also sent my board by mail if needed.
thanks

Did you ever get this to work? I looked over your pictures and found an error when you put the 040 back in. You should have shorted pins 1 and 2, 7 and 8, but you missed 11 and 12. These should have been shorted too as this is the ground for the cpu! With out that you may have damaged the CPU. Also for the 060 with the regulator in place did you change the CLKEN jumper ? also you have to change two jumpers on the board mark 060. did you do this ? with the 060 in there you must have the 060 rom and you must have the 060 rom jumper shorted to allow the cpu to boot from the rom code. with out these changes you WILL get a black screen.


Oh i just noticed there are two dead cards now if only i had more time.............
and a A3000,A4000

i know its a bit late but i can confirm that a 1240 and 4040 cannot be converted without the mach 131 part in place.

[alexh]

Two Mach131's in the case of 4040.

Ah well. Bummer. I could get the blank chips through work but with nothing to program into them

alexh,i love the way you think.

yep i had a shed load of these dispatched to me.but they went walkabout during postage.oh well.

[alexh]

I'm pretty sure the original chips have the protection bit set so you cannot dump them

Would be good to confirm that though. My programmer cant read them (Dataman 48UXP)

I noticed that the capabilities of the MACH131 and the MACH130 in terms of capacity are identical but the logic speed grade is different.

same conclusion here,a good friend of mine was going read the mach chips and make a dump,as mine is the same model as yours.unfortunatly the parts never arrived so,i told my friend not to bother(i doubt he could do it anyway)

i had a sneaking feeling that all the mach131's on the 1260 and 4060,where one and the same part as they where not marked individualy.
for assembly purposes.as the parts never arrived i never found out.

as a unrelated topic ive been thinking about buying a willem programmer for custom kickstarts,are they any good and can i use a 27c10 in it maybe with an adaptor?.

regards roy.

if difference of mach 130-131 is the speed, test 68060 at 20mhz

i dont think its"just" the speed of the mach130 thats the problem,as also, as to what way the gates have been programmed.on the mach131.

plus: i dont think an 060 at 20 mhz would be much good to anyone im affraid,thats if it could be underclocked to that speed at all.
is all it would show is that it was programmed the same way.in itself isent much good on its own without knowing whats on the part in the first place.

[cpiac64]

but if the schematics is equal and suppose is equal the source of mach, only change is more pin of 68060

6 Years have passed since I opened this thread... Doesn't time fly?
I was busy with life... new country, new house, new wife, new child but remain an Amiga fan.

Anyway, I finally have time to look at my Apollo 4040 card that remains faulty.
I simply gave up the 060 upgrade. I now just want to get the card to work with the 040 as it did before.

Now I am not sure that the CPU was killed after my attempt in upgrading the card to the a 060. Therefore I plan to first swap the 040 (XC68040RC40M) with my other 040 CPU (from my 3640 board XC68040HRC25E) to see if the card comes back to live.

Does anyone know if the 25Mhz CPU would work on the Apollo card? Of course with an 50Mhz xtal not the original 80Mhz.
