... unless you already have a BIGRAM card :D


Zorro III RAM is fast, but is it comparable to local memory on the accelerator?

Not even close, AFAIR.

I know there've been a few speed tests posted before.  Personally I'd be more curious to see speed tests comparing an A4000 with a A3640 and that 64MB motherboard memory hack and vs. one with an '040 card with local RAM.

Is A4000 motherboard memory faster than memory addressed through one of the Zorro III slots?  (I would assume so)


Ooooo!  I never knew about that hack.  Neat!

I highly doubt it, but I'll defer to the more knowledgeable folks here.  For my own (key word) personal use, it would have been good enough.  A moot point, however, as I've got my eye on another road bike instead.


I can imagine it's fast enough for my purposes, as well.

There were a few kits available on eBay, too, a few months ago (which is how I heard of it).


I like the idea of this 64MB hack.  In Acill's thread he mentions he's done this for a customer, so I would infer he could do it for others.  Had I known about it before I sent him my main 4000D board I would have had him done it alone with the PIO2 upgrade.  I have one more board to send, so that's on my list.
