Upgrading Apollo 1240 to 1260 a definitive How To Guide - Page 13

DoogUK · 04 May 2009, 10:01

Oh dear..it seems it must have gone to apollo heaven.

05 May 2009, 18:45

I bought an Apollo 1240/40 and a 68060 cpu for a long time ago. This thread seems very interesting to me for an upgrade of my card. Unfortunately, my 68060 is not one with that mask that could get around 80 or 100 mhz. Just between 50-66 mhz is already a good beginning.

@ Dimlow : Do you plan to jump to 100 mhz now you've reached the 80 mhz ? So you could get 50 mhz for the ram controller, that is better than the actual 40 mhz.

DoogUK · 05 May 2009, 19:27

I think the ram clock is not happy running at 50mhz, he is going to try and run the memory clock at 33mhz and then go for the 100mhz barrier

Dimlow · 06 May 2009, 09:21

Seems i have stopped getting notifications when this thread changes Mmm.

@yanovitch75 Seem from what i have read that your cpu will be ok. But will run hotter so will need a fan on it.and 50Mhz or so, so yea you got it, Oh and be warned, the 68040 is not that easy to remove. you could damage the board if any force is used. I believe two boards i have here have this problem and i cant fix them. Oh yea, it wasn't me that removed the cpu's on them!

100Mhz is only something i might play with when I'm real bored. But what Doogy said is right. These clockings for the memory could be changed to allow for slower memory. But i doubt id ever get round to it. 80 Mhz its just fine for the 1200. I think the cpu speed is now not the bottle neck of the machine. If only there was a way to overclock the graphics on the 1200 !

Thanks for advise. i'll take care when i'll try to desolder it. Till i acquire more expertise for doing this, it won't touch it.

But, haven't you clocked ram successfully at 40/50 mhz ?
Perhaps, i haven't understood all that means...

Dimlow · 13 May 2009, 08:35

Well, I think someone should just try it before i go and change the clock circuits for the memory. And what i was saying about them memory clock is that it runs at 50% of the CPU clock. So 50% of 100 MHz is 50 MHz, that's considered quite fast for the 50 / 60 ns RAM we can put in these Apollos. So maybe its possible to knock the memory clock down from 50% to 33% with some electronic wizardry. Slowing the ram to enable us to overclock the cpu further.

As of removing the CPU, have a look at this, its from another thread, but it really should have been her in the first place. I have made pictures of my latest conversion of a Apollo 1240 to a 1260 at 80 MHz

it must be something different what holds 1260 to 80mhz, as 4060 board can run at 100 with ram on 50.
stepping down to 33 for ram probably will not help

Dimlow · 14 May 2009, 23:36

Jens told me, the limiting items on the Apollo 1240 -1260 boards are the Mach chips, or though they are rated at 100 MHz they may not work at 100 MHz. He was really douting that they would be stable at 80 MHz.What would he have to say about 100 MHz i wonder ? But besides this, the 74f74 chip is only rated at 80 MHz, but they do run at 80 MHz, as can bee seen from the many conversions already. But i have replaced the 74f74's with faster 74ac74 chips on some boards that would not run at 80 MHz. It solved the 80 MHz problem. I think we would be pushing stability if we go any further.
All that remains really is for someone to test it! Memory wise it may actually work, but if not, then still it may be made to work be dividing the clock down for the memory. I was only thinking ahead. This all of course means nothing at all until someone tries it. I wont be doing that any time soon.

Sorry to "betray the movement", but I'm moving to Blizzard 1260...

Soon a no-working Apollo 1240 for sale...

Hi there,

I've got my apollo upgraded by a friend today, but there's a problem now. We used xc68060rc50 but haven't had any other oscillator than 80Mhz so it's possible that this early 060 can't handle it. When I tried to boot the system that worked fine on 040 it would just display Software Failure message and keep rebooting in this manor. I've googled up that I need updated libs and tried both those from apollo installation disk and some others from phase5. Both didn't help. I've played with my startup sequence a bit and commenting some stuff out got the HDD led to blink for a bit longer so I assume it at least try to read it. I sense there's something terribly wrong as I can't get to the boot menu at all!! To make it more puzzling it boots cannon fodder from floppy disks no problem. Is anyone familiar with these symptoms ?

EDIT: it'a a classicWB installed bo my other friend before he sold me his amiga. Is it possible that something in the system could be 060 incompatible if it was installed when the system had only 020 ?

Cheers,
Marius.

DoogUK · 20 September 2009, 20:26

exact same problem i had when i forst used my apollo 1260.
delete the 040 lib then it will boot

sqward · 20 September 2009, 20:40

I've tried that with no success

Is it normal I can't get into boot menu ?

DoogUK · 20 September 2009, 21:09

if its not accessing that...the cpu cannot handle the overclock.

sqward · 23 September 2009, 11:10

Hi guys. I've got it working with 50Mhz oscillator and libs from apollo install disk. Thanks!

DoogUK · 23 September 2009, 11:24

great news...those xc's are normaly good for 60-66mhz.

sqward · 23 September 2009, 14:51

Can someone share a SysSpeed module with 50Mhz,66Mhz and 80Mhz 060?
Thanks!

DoogUK · 23 September 2009, 18:33

i'll do the 66mhz and 80mhz ones later this evening...but i dont have a 50mhz xtal i'm afraid.

03 October 2009, 08:54

Just acquired an Apollo 040 card. Would like to upgrade to 060 sometime in the future, but dont have the tools and equipment to do this myself.

Crystal is socketed, CPU (XC68040RC25) is soldered.

Given I'd have the parts needed, should an electronics repair shop be able to do the modifications for me?

In the meantime, I will probably overclock the 040. Any suggestions for a low profile cooler/fan?

Cheers,

Kaj

Hi !

>Just acquired an Apollo 040 card. Would like to upgrade to 060 sometime in the future

First, the Mach chip on your card is 130 or 131 ?

>Given I'd have the parts needed, should an electronics repair shop be able to do the modifications for me?

I can for 20 €
New 68060 rev 6 (71E41J) for 30 € (can reach 90 Mhz)

But you need a voltage adaptator

A+

DoogUK · 03 October 2009, 11:08

Your best bet is to get Per Gunnar over at Amiga.org to do it for you....he charges less than an electronic shop will to do the upgrade.

In the meantime, when i overclocked mine i took a low profile heatsink and fan off a graphics card to cool mine but the old 486 fans fit perfectly.
