He posted this image on "page 4" of this thread. I'm not sure if that still stands, but it's your card, so i wont tell you what you can, or cant do...
I'm thinking he might have changed things before production making the info obsolete, possible even risky to use. Looking at the Vesalia image it's a 25Mhz cpu, with a 16.6MHz setting, if i read everything right. Seams unlikely, and if he changed anything, well, then "everything" goes out the window... Good luck... Edit On the other hand, AmigaKit seams to have used the same 33MHz version image for both the ACA1232 25&33 MHz images, And there the setting does match the one in the picture above here. CPU, & speed "jumper" seams set to 33Mhz. Oh, and the image seams to show the backside, where as the store images show the front. /Edit Last edited by Mr B; 08 May 2013 at 21:16. |

I have the ACA1232/33 and as far as I can tell PCB's are the same. (this is my evil mind thinking about what I should do next) |

They are supposedly the same PCB, but i imagine that they are loaded with different software configuration, and might even come with different speed memories and what not. Just saying i'm not entirely convinced a 1220 can be upgraded to a 1232 in the home office. Upgrading from 68020/16 to /25... sure, that might be doable. I'd hate to be the one trying and finding out that it's not, but who ever tries, good luck.
If we are really lucky, Jens brings a few words on the topic, like "might work, but your on your own" or "No, i doubt that will work, but comes down to luck of the draw with memory speeds" |

But to swap out that plastic 020 for my Gold one and overclock to 25mhz would be nice |

CPU Upgrade
I've already asked in the other thread, but i think Jens haven't seen it. So here it goes again:
@Jens Is it possible to upgrade the 33MHz CPU on a ACA1232 by a 50MHz CPU? I mean, of course it's possible to unsolder the original CPU and solder the 50MHz version, and i have all the tools and the expertise to do so. What i want to know is if it's possible to make the board drive the processor at it's new clock rate? In the table silked on the board there are jumper wirings for up to 40MHz. Is the 50MHz clock possible with the same (standard) FPGA core? Beside this question, am i wrong in thinking that i may benefit of the CPU change anyway, as the ceramic 50MHz version, even clocked at 40MHz would heat a lot less than the original plastic 33MHz version? Of course, i'm not worried with warranty matters... Thanks! |

Seeing as Jens generally tries to get good performance from the stuff, i'm not sure it's as simple as selecting the right jumper setting, and hey, your done. On the other hand, it's pretty simple to test the settings, if one has the balls to replace the CPU. It's the software, firmware, or what ever it should be called, in the CPLD that might throw one of, as well as the components actually used. Steve, you had both a 1232 & a 1220. Compare the memory bits, and if they are the same, then the chance is good that they would work with more of the CPU's. In that case i honestly think it's only the quality of ones balls & the CPLD content holding back.

That's neither a complaint about the website, nor about my products. Note that 150-pin CPU slot connectors are not a product that I sell, but a necessity for making CPU cards. I have paid well over 20k EUR for the tooling, and it's up to me to decide whether I support somebody else's project or not.
One thing you have confirmed with this public complaint is that the support ticket system works: You ask, you get an answer. Quote:

I don't have a memory controller with the required amount of wait states for 50MHz CPU clock for the ACA1232, and I don't even know if it's possible to fit it into the logic (haven't tried yet). Right now, the memory controller benefits from "4 states only", resulting in two state bits only. Once more wait state would require an additional macrocell, and I have my doubts that this can still be routed in the 72-macrocell CPLD. Note that the old ACA1230 used a 144-macrocell CPLD with plenty of routing resources. Quote:

Back on the main subject, any release date for the ACA500? Still can't see it at Amigakit's.

New products for C64 and Amiga from Individual Computers
I'm happy that we are about to have more solutions to the Amiga's 15Khz problem. Although I found that the SCART-to-HDMI is a much better solution that the GBS-8220 and that piece of crap eBay "15Khz to VGA" thing, Jens' MKIIs and hopefully the ScanJuggler will fill an ongoing need. His accelerators also fill a need the "Community" has, and with the addition of the KS ROMs they will make life easier. It would be nice (but perhaps not economically feasible) to have more X-surf's, Buddha's, and the like, but his company is a business; those of us who run or have run a business know your limitations -- and those of us with familiarity with German (and EU) laws and regulations know that the EU government(s) would rather tax and regulate you into the ground than promote business and growth (isn't there a financial crisis over there?).

The SCART-HDMI adapter is very very good but not perfect, Jens Indivision products are still the gold standard.

Someone has already swapped out the 30mhz 030 and replaced it with a 68030 50 mhz set to run at 40mhz using the resistor settings on the board. It runs stable and cold cos now obviously you are actually underclocking the 030-50mhz cpu and running it at 40mhz getting an increase in performance (He used the 030 50mhz "B" CPU) Using 0 ohm jumper on R2 and R4

Not sure if I get to all that this week. It's a bit hectic here since the results of 2011 have been published (*very* bad numbers). Jens |

First post for me , but i had to say, im quite excited about this product. I cant wait to buy one of these!
And sorry to hear about the bad nummers, hopes it workout anyway . |

Echoing the last post, I registered here solely for the purpose of keeping up to date on the release of the ACA500. Looking forward to purchasing one!

Well, I'll do my part to polish the 2013 numbers when the card is released.
