New accelerator on the way

[Richard42]

Vesalia shipped my new ACA 1231/42MHz A1200 accelerator today!  I'm super jazzed about getting this, because my current accelerator is a bit flaky.

I have attached 3 screenshots.  The first is of my A1200 with no accelerator board installed.  The second is with my old accelerator, which I think was an MTec.  I bought this cheaply off someone on ebay.  It was pretty flaky (lots of crashes) when I got it, and found that it was OC'd by the factory (40Mhz clock speed but 33MHz 030 CPU).  I "right-clocked" it back down to 33MHz, where it's much more stable but still crashes sometimes.  The last screenshot is with the ACA1231/42.  Almost 10 MIPS (9.79).

Do I need to do anything to enable the MMU with WHDLoad or any other programs?

I'm running WB 3.1.  I haven't installed the tuning software yet, so I don't know for sure what it does.  I can see 3 different memory areas in SysInfo: a 2MB chip ram, a 1MB slow RAM 24bit DMA, and 62MB fast ram.

I have attached a pic of the board itself.  There are two 44-pin QFP chips near the amiga edge connector which have had the top surface ground away, so no marking is visible.  I think it was done on the board, because the small TSOPs underneath the QFPs had some dust on them.  I wonder why they would remove the markings on these chips.

G'day Richard, have you had any stability problems with your ACA1231?  Vesalia have notified me that they've not been able to ship the ACA1231 due to some serious issues with the first batch.

I haven't used it a whole lot yet (maybe 3-4 hours total), but I have not seen any crash.
