(sorry for not posting it in this thread, but I didn't find an easy way to put the table here... any ideas?)

Anyway, I hope it helps.

Big book of Amiga hardware has a pictures, but not a jumper settings. http://www.bigbookofamigahardware.com/bboah/product.aspx?id=180

Amiga.resource.cx has two entries for this card series 1 and series 2. Ity has a jumper settings for series 2 card and RAM32 module, but not for series 1 card and RAM8 module.

With google I have found some questions for this, BUT all answers point for series 2 accelerator and RAM32.  

Serie 2 card jumpers settings doesn't help me.

I was looking them from there :( Just wondering are they updated page just few days ago?


Sure, after your question I looked for the jumper settings and updated the A3001 description accordingly.

Just wondering, cache / MMU jumpers doesn't seems to work as descripted. My board is jumpered so that caches should be disabled, but they are not.


MMU and cache settings can also be changed by software, so please try booting without startup-sequence and have a look again.

Also memory board is jumpered so that ram should be mapped to 32 bit space, but it uses 24bit Zorro II scape.


Actually, there is no jumper for that - J5 on RAM8 is just to select between 4 and 8 MB.
But anyway, I also would have expected the memory not to appear in Z2 memory address range. No idea here...

Wondering why and how only 50mhz version of card uses it own address space.


Why do you think the 50 MHz model is special in that regard?
