if it plugs into the 68000 socket, will it work in an A2000 also? besides clearance issues with the drive cage or whatever?

As far as I know, the A2000 uses the older (huge!) DIP-style 68000 chip, whereas the A600 is surface-mount...

How fast were you going to clock the 68020?

I would be interested in 1 (or more!) of these for the A600!

I can also buy one of those cards for my lovely 600 according to the price and shipping possibility.

This could work with the A2000 series flagship computers as it also has the same CPU as the A500.  (Just ask George Campbell) LOL

Man, someone accused me of being obsessed with Doomy a couple of years ago, I think you've taken my mantle TJ!;-):-)


Nice work by the way!

Having a nicer upgrade solution for the A600 would be wonderful. I would certainly consider buying a modern option for a more transportable A600 machine.

Hallo,

The plan is to clock it at 16 MHz. Higher clocks can be achieved, but I don't know how much those 68EC020 can be pushed. They are -16 parts, means were meant for 16.67 MHz, a couple more MHz can be squizzed, but another limiting factor will be the flash rom. 70 ns flash should work even at 20MHz... but all that should be tested.
Remember that memory will be accessed in 3 cycles (except chip of course), so that should achieve maximum throughput... and so performance.

I'm a bit late with this due to my phd demanding some work from my part ;-) but hope to get again on track very soon.

The A500 version uses the DIP connector, so should be pluggable in an A2000, but I don't have one to test... (any volunteers ;-))

regards, and thanks all for the great support !, I hope I can deliver something soon

What's the PhD in?

Lemme guess - its gonna be Physics, Computer Science or Electronics right?

[hppacito]

Until I was arount 18, I was sure I'll study Electronics. But that very year I changed for chemistry. I think gives more of "how the things work" than EE.... time will tell ;-)

Please include me on the list of buyers when they are ready!

hi! exist any new from the project?

[hppacito]

Ja,

I'm still working on it to fit all components in such small board !, and down to 2 layers.

Thanks for the support !

[rigardie]

hi! again you still working on this?
thanks

A500/A600 Accelerator a dead project???

[Jethro_Tull]

Hello there! Glad to see that someone's still thinking about old non-AGA Amigas.  I really like your posts, down to earth facts and to the point progress reporting. They inspire confidence.  I would cerainly part with my hard earned cash to upgrade my little A600!  With the ACK for the A1200 and your accelerator for the A500/A600, retro Amiga owners are in for exciting times!  

Good Luck with your exams, and of course with the accelerator!

yeah what's up with the project???
