Note that the ACA500 firmware does NOT know about the ACA1221 yet. We need to make a firmware update for that.

Jens

I will probably get the 63M licence but I know that it will be hard for me to use it all.

Will you add pmmu dlc (down loadable configuration

)? NetBSD will be slow but I like the idea of being able to run it.

@TenLeftFingers

Cool, well if you can fit it in, the offer's there, but good find on that Irish guy, definitely a lot handier than shipping to the UK! His website could to with a bit of proofreading, but bookmarked anyway and looks like the right kinda guy for that sort of work.

Do you know where he's based?

MMU is a separate component on 68020 systems - one that's even harder to find than the CPU itself (part number 68851). So no MMU on the ACA1221, and therefore no NetBSD.

Thanks buddy. He's based in Waterford and says an A600 cost EUR 15 to post to him from within Ireland. It's not a huge saving really, but there's more peace of mind that if anything goes wrong it should be less hassle to sort it out.

He said if I send him the accellerator with the machine he'll make sure the timing fix is right for that card and because I have the caps from AmigaKit already I won't have to pay for those.

Jens

I was thinking of one implemented in FPGA/CLPD but it would need cooperation with the NetBSD devs

Schoenfeld · 29 August 2015, 22:51

All ACA1221 pre-orders have been tested&packed - some cards shipped yesterday, some today, and the majority will be shipped on monday. Product has status "in stock" now. Another release date met ;-)

Jens

Daedalus · 29 August 2015, 23:19

Another Saturday well spent Jens?

Not that I can say much, sitting here coding on my Saturday night...

Well done!

dJOS · 30 August 2015, 00:30

I hope they do well Jens and we get an aca1230 version as a result.

SKOLMAN_MWS · 30 August 2015, 00:47

Next ACA with audio codec, not necessarily the DSP.

Looking forward to getting mine

What about ACA1221 and ACA500? Will they play along nicely?

See post#199: http://eab.abime.net/showpost.php?p=...&postcount=199

Jens

Lord Aga · 31 August 2015, 09:24

Yes, that post prompted me to write

I was hoping you could shed some more light on it. Will we have to send ACA500s to retailers for the upgrade ?

Schoenfeld · 31 August 2015, 10:28

It's a pure software/flash update.

Jens

Lord Aga · 31 August 2015, 10:48

Ok, thanks !
That's a load off my back

CrashMidnick · 01 September 2015, 10:01

Jens, any date for the ACA500/ACA1221 compatibility ? I bought it mainly for that

Thanks

Schoenfeld · 01 September 2015, 13:57

Basic compatibility is given already. It's just that the menu system will not recognize if MapROM is not licensed and may try to activate it anyway. Same for memory options, which may need small adaptions in the code.

Jens

Still not totally clear about 'timing fixes'? I'm planing to buy the card in a few weeks but don't fully understand about 'removing' some of the capacitors on the A1200 Mobo. I have an original Commodore A1200, does it need these timing fixes for the ACA1221 to work?

Both Commodore and Escom have made all kinds of mistakes when assembling the A1200. They all have in common that timing fixes that were required for very early Budgie revisions have been applied, although Budgie was already the new version.

To put it simple, your board will not be stable with any accelerator if one of these four components is assembled: E123C, E125C, E121C and E122C. All of them are located on the bottom side if the A1200. You won't get around opening the computer and checking yourself if these components are assembled. The revision number of your board says nothing. The year of your board also doesn't give any information. The one and only thing you can do is to check your board.

just out of interest I use to have an Escom a1200 with a Blizzard mkIV '030' but don't recall having any noticeable problems? if I have any of these unwanted caps I guess it just removing them with a soldering iron.
