I am looking for info on A1XE or board docs pdf . I have one that came with the board itself (directory "boarddocs" on the Eyetech's install cd). Afair, there's a newer version that was made public or to the dev list only. I remember having it on my A1 hd, but A1 is dead. What I need is list of all available clock multiplier settings (boarddocs on cd lists upto x5 afaik) and if possible the pdf file itself.
Any help will be appreciated, Jack

Thanks for the pdf, that's the file. Unfortunately there's no description of multiplier dip switches. Thans for the pdf anyway. I should have put it on CD when A1 was alive.
@DJBase
Thanks for the pointer
@Raziel Now the relevant news: highest possible the max speed of the A1G4 module is 1066MHz. That limits the choise of cpus to get for reflow to 1000MHz ones.

That's not right, you can set the switches to get multipliers like 11/11.5 (can't find the piece of paper at the moment). 1066 MHz is not the fastest.
You can certainly set a G4 to run at (IIRC) 1.3-1.4 GHz. I'll try to find the data and get back here.
You could try asking Excalibur or PowerAmiga, they should have the data.
Hmm, thanks for the pointer, gone to ask.

Sorry, I can't find the table I drew up some years ago. I can't even remember where I got the info from, but I do remember changing the switches and reading the CPU speed from U-Boot output.
If I find it in the near future, I'll send it to you. It's not the sort of thing to post in public, because some people might try it just for fun and break something.

I will be grateful, TIA

Indeed.

Can anyone confirm this? The choice is between 7455@1250MHz (200US$) and 7455@1000MHz (150US$) replacement cpus.Couldn't find the 1400MHZ version (although it was produced).
Thanks in advance, Jack

Warning: I'm talkng about real 1250 and 1400 megahurts G4s, not the ones shipped with A1XE. It is not an overclocking thread...

I used to have a sheet of paper from back in the dreamtime when I first got my A1. I made up a matrix of the 16 possible switch combinations and the CPU multipliers that you got from each.
Although I can't find the damn thing now, I do remember multipliers like 8x (x133=1066), 8.5x, even an 11 or 11.5. The multipliers were all over the place, binarily speaking, so you couldn't set up the switches without knowing the code.
Now 11x133 = 1466, so it should possible to get speeds of that order out of it. I'm sure I remember 1.3-1.4 GHz in the table somewhere.
I'm certainly not running my A1 at those speeds. With the dearth of hardware around, I'm not going to risk losing it and I'm running it a very conservative 800 MHz. Yes, it runs fine at 1066 with good cooling, but its life would be reduced (like any hardware that is run harder).
We've reorganised the house since the kids moved out and I'm sure the sheet of paper has been "filed" somewhere, but I've been unable to find it.
Jack, did you get on to PowerAmiga? He runs his machine at a good clip and might have the data you need. Also Excalibur (aw.net) might have the same data. If you can't get in contact with either of them, PM me and I'll email them.

Tried to pm both the day you mentioned them first, now emailed PowerAmiga. Also posted the question on AW. That 1250MHz option looks very viable. 200US$ + 55$ on reflow (professional one)+postage makes it look like bargain. The only thing that'll stop me is new module from Adam (or whoever is going to release one).

I waited a whole year for replacement modules to materialize. And I can't afford a whole new system. And if it won't work my A1 won't become more dead than it now, it's not as if I was talking to make a working A1 faster.

Please refer to our PM's from amigaworld.net . this avenue is already being explored and awaiting results. Bear in mind that the people concerned also have their own hardware projects in progress and have to devote the majority of their time to those projects. This kind of experimental work is being carried out at our own expense and to the possible detriment of our own hardware so all we ask is your patience which must surely be cheaper for you in the end. If you have your own resources there is nothing stopping you experimenting. Good luck to you if that is the path you choose.

Thanks for the info, I will follow the advice for a while (untill whatever comes first, the repair service or queue big enough here of ppl willing to experiment on their own to actually produce an order that is big enough to be checked out with cpus resellers)
@tonyw:
Huge thanks for the table you talked about, it realy clears the confusion up. So it looks like the info issue is resolved now.
Jack.

I got my A1XE without ANY documentation in printed or electronic format. Could you please also send me the PDF documentation. That would possibly be of great help to answer some of my questions regarding the A1 Hardware!
