Upgrading Apollo 1240 to 1260 a definitive How To Guide

[johnz]

i want my apollo 1240 to be a 1260 holy god!
maybe he doesn't stand the fact that apollo 1240 are far better than any of his aca 030.
030 is to weak to allow mutlimedia use of the amiga. what 030 can't, 040-60 do!

CORRECT it does allocate 16 mb chunks

help, i have broken the hole P3 as TT0, please i need add a wire from TT0 to ??? (i suppose a pin of mach131)

i need verify signal D25 to ram and to 74fct16543 but n° of pin?

From first looks at the code i see no reason why you need a special version for the 060, the only reason i can see, is that later version of the firmware only after v 5.21 has support for the 68060.library. so even if you have an 040 in your Apollo, this code will still work. and can upgrade to an 060 with no need to change the eprom except for bug fixes. There may even been some advantages to upgrading if you have on 040 or though i have not looked at this.

By the way i am by no means an expert programmer. Last time i looked any 68k assembly was 1996. All i have done so far is use babelfish and read the comments in the code. If someone else wants to dig further they are welcome to

As a bonus to me, the cards i have purchased have rom version 5.55, this version of the rom supports the 060!!!!!!

right i am so late for work i must go now..

AND EVERYONE HERE SHOULD GIVE A BIG BIG THANK YOU TO FRENCHSHARK

THANK YOU FRENCHSHARK!!!

does anyone has the 131 mach info and the eprom content.

thanks in advance

[roy bates]

the mach info will never be released as its property of jens at individual.

the eprom contents is knocking around all over the place even i have it somewhere.

i have a problem, i have 3 apollo 1240 for upgrade but all work only with the clock is /2 (xtal 80 - clock 40) or (xtal 56 - clock 28), with xtal 50 or 56 and clock 50 or 56 don't start

i have another problem, with 68060 the command setpatch restart the apollo, i have copied library but don't change

take pictures of the boards,so we can see it.

@ Dimlow

Thanks for this awesome thread !

btw, found v1.0 of the Apollo 1240/1260 User's Guide but does anyone know if this is the latest version?

i dont really understand what your trying to say here.

if theres a 040 on the card then it will half the clock,if not then its supposed to 1 on 1 with the exception of 50mhz 060 which is supposed to be in the 060 position.
im only saying this because the cards power jumper is set for 5 volts still.
other than that its a hardware problem.if it doesent work in 060 mode.

[cpiac64]

the board now have 3.3 volt and cpu 68060rc60 at 60mhz, work but the ide is slow and sometime dont start, i suspect the cpu is remarked, not original.

sometime have problem with fastram and need reboot

the cpu is hot

tomorrow test with xtal 50mhz

Is there a place to get the regulator board made? I have a 1240 I want to upgrade for a customer.

Make sure you have a Mach 131 and not Mach 130 chip as the latter is an older version which can't be upgraded to 060

Yes it can, several people have upgraded their Mach 130 Apollos to 060. It depends on the program code inside the chip whether it's upgradeable or not.

if jens helped make it why aint he making them now its a great card , so sad.

[alexh]

I don't think he did? He hates them. He's just the rights holder now having bought them?

As far as my limited knowledge goes, Jens had no hand in designing or developing any of the ACT / Apollo range of accelerators.

Jens accelerator development has been specifically based around the low end CPU's such as the 68020 and the 68030 - the later of which has very little difference in processing power.

While Individual Computers has released some pretty fast 030, fast memory, low latency near zero wait state implementations - the company has not ventured into 68040 or 68060 processor based accelerator cards.

This is likely a three fold reason, where getting these CPU's is increasingly expensive even in modest quantities, finding said quantities of these depreciated CPU's and finally the complexity of the logic to get it to function on a wide range of A1200's.

Personally my favourite product from Individual Computers is the ACA620 - its a little stick of dynamite for one's A600!

Looks like this one is a 131. I see Mach-131 printed on the chip at least.
