It's not a big problem, I have A4000

Do you have the voltage regulator schematic / pcb?

Look in the upgrading Apollo 1240 thread.

piemmeweb · 29 September 2009, 10:40

I have one of that CPU http://cgi.ebay.it/XC-68060-RC50-100...mZ260251117369
that's ok for the apollo 3040 upgrade? need I to change the oscillator? with a 50 Mhz version or other value?

Also I taken a look to the 1240 upgrade thread and seen the voltage regulator built from "Dimlow"; I contacted he by PM but not reply at this time. I need to know if that voltage regulator can be used on the apollo 3040 with no modifies or need to be modified. I already have pin jumpers on my A3040 so I need to change male connector with female connettor on the Dimlow's VR , but it will works fine?
many thanks

many thanks!

Sure, but that is an older 68060 with 1F3G mask and will not overclock well. You need an MC68060RC50 part with mask E41J if you want to go for 80MHz+

Yes, 50MHz

They are identical.

alexh · 30 September 2009, 22:52

I dunno if anyone would be interested but I found these on ebay.

Beats using pin-strips?

I prefer to use strips... I've not seen yet the socket under the 68040 but hope that I can modify that because my desoldering station cannot desolder all the socket

My first step is to build a voltage regulator like Dimlow...

alexh · 30 September 2009, 23:20

The socket on mine is a bit beat up. But I know what you mean.

piemmeweb · 01 October 2009, 18:11

a simple question, my 3040 have a 28 pins eprom mounted on a 32 pins socket, i assume that's the 27c128 eprom for 68040. Need I to use another 27c128 for the 68060 eprom or need to burn a 27c010 32 pins for that?

rkauer · 01 October 2009, 23:10

You need the 27C010, the 27C128 don't have room for the '060 code.

piemmeweb · 02 October 2009, 23:13

Well, I burnt a 27c010 eprom and bought MC68060RC50 cpu.

But with MX68060RC50 I can overclock it up to 80 Mhz with original oscillator or need to replace oscillator with another of 50 mhz?

Now I got a problem: I'm looking for TS1085 (to build the voltage regulator) but not found it. Can you help me to find it or know equivalents?

It depends, there are more than one MC68060RC50. It needs to have the mask set E41J (number written in top right corner of chip).

You will have to modify the clock jumpers on the underside of the board to successfully overclock to 80MHz and keep RAM happy.

I bought MC68060RC50 mask 71E41J ;
I seen the modify but unfortunately I have not a SMD desoldering station so I think that cannot desolder and resolder the 100 ohm resistor.
What's the problem if I will not apply that modify?

But, if I replace the 80mhz crystal with 50Mhz version? the cpu will run at 50mhz and no smd resistor modify needed?

The 71 is not part of the MASK code

It doesn't work.

Yes.

piemmeweb · 29 October 2009, 21:57

I tried today to upgrade my apollo 4040 to 4060 ...

I applied the following:

- MC68060RC50 CPU
- 50MHZ Crystal oscillator
- Eprom 27C010 with 4060_5.21_unknownchip_b_27c010.BIN
- Voltage regulator with EZ1084CT

But it DOESN'T WORKS!!!

I encountered a strange problem: the power led flashes rapidly and after 5 seconds I hear quite toc-toc-toc from power supply... the power led switch off and the power supply too...

what can be the problem? is the CPU or the voltage regulator or whats?

I tested voltage regulator ... 3.48V with no loads...

please help me!!! thanks

There are a few excellent "Desolder Surface Mount" videos on YouTube. Just skip the hick modding his xbox vids

It's easy to desolder and solder an SMD resistor with a normal soldering pen.

The toc toc toc, if it's a switching supply, is the PSU detecting an overload or short on one of the voltages (maybe it's all of them or just the +5V, guess it depends on model).

Disconnect the PSU and measure resistance between GND and the different voltages on the Amiga. If one has <5 ohm, it's shorted. Then unplug peripherals until the shorting one is found. If there is a short when there is only the motherboard left, you have to find the fault or get a new one.

If no short is found, it's probably the PSU, try another.

piemmeweb · 30 October 2009, 10:26

Well, I replaced PSU and no toc-toc-toc now.
But the screen remain balck, the machine doesn't boot.
I tried 3 CPU MC68060RC50 and tried the crystal on another accellerator board.

I'm thinking about the eprom, maybe I not used the correct firmware, anybody can send me or help me to find the correct bin file?

thanks!

Or maybe you have MACH130 instead of the needed MACH131... Which also is damn hard to find

alexh · 31 October 2009, 14:41

@8bitbubsy

There is no real evidence (particularly on Apollo 40x0) to show that the MACH number is particularly damning. Certainly not with 50MHz crystal.

piemmeweb · 31 October 2009, 15:50

Unfortunately I have all three MACH 130 ... no solutions?

Do you thin that with three mach130 the mod can be still applied? can you help me to find the correct 4060 bin file for the 27C010 eprom?
