A3660
« on: May 01, 2022, 05:16:37 PM »
Hi all,

Anyone had experience with the A3660? Im looking at this for my A3000D:

https://amigastore.eu/en/827-a3660-rev-11.html#/

Ive got a CSMKII 060 in my 3000T. How does the A3660 compare? The MKII has got RAM but does it make a visible difference? MIPS quoted for the A3660 @ 60 MHZ look to be more than what SYSInfo shows for my MKII @50 MHZ c39 MIPS.

Also anyone had experience of AMIGAStoreEU how do they compare other AMIGA stores - Amigakit, Retropassion, Vesalia, Alinea?

Any accelerator with local memory will be significantly faster than an A3660 for any games/apps that move lots of data into and out of memory. Games with texturing like Doom/Quake/AB3DII TKG, for instance.

A3660 will use motherboard ram, so youre looking at max 14MB/s read for a 3660.

Your CSMk2 at 50mhz has approx 33MB/s read, so it is over twice as fast in this respect.

More ram speed comparisons can be found in this thread:

That's what I was reckoning - fats ram on the accelerator board like the CSMKII would make quite a bit of difference. The A3660 will still be an improvement on the stock 25 mhz 030 though. I did manage to get a v3.1 A3640 with a low height heat sink working years ago. I might give that a go again.

Yeah, in terms of pure speed the 50mhz 060 will run rings round an 030. And for stuff not involving ram intensive stuff then there’ll be little difference between the a3660 and CSMk2 at 50mhz - rendering a vistapro scene for instance

That's awesome that Amigastore has them populated. I bought a bare board a while back and trying to find a 68060 with mmu/fpu is nuts right now. 700+ dollars and up just for the cpu

Yeah - looks like that prebuilt has the LC 060.

I actually sent Heisener a request for price on NOS Freescale 060s. Minimum order of 5 units at 750USD a piece  :o That makes that fully populated one a right steal TBH

My CSMKII has a rev5 060 with MMU and FPU. I picked it off ebay years ago with the SCSI module for less than €200! At the time I thought I'd got a good price looking back I got an absolutely fantastic price given how prices have moved for full 060's. I saw rev 6 being touted on Amibay for silly money.

What are the limitations of LC 060 in everyday use when compared to full version of 060?

LC lack functional FPU, so as long as you stick with software not built for “full” 040, “full” 060 or 882, it will be ok. Back in the days, using LC040 and LC060 was a bit of an oddity, so not much software is optimized for them.

I stumbled across this:

https://www.exxoshost.co.uk/forum/viewtopic.php?f=75&t=5188

This looks awesome - on board ram and IDE - if it all comes to fruition I'll get one of these. Some test boards on youtube show them working pretty good.
