ography is not tolerated on EAB you know

p.s. ALT+0169 on numeric keypad will give you a © symbol

Jakodemus · 12 March 2010, 22:05

Droool......

I want one with 1GB of ram. Can I have it now if I ask nicely? ;D

Sure, but (c) is old sk00l!

... and old sk00l us dead sexy!

r6stu · 12 March 2010, 23:12

specs? price?

Zetr0 · 13 March 2010, 02:39

I cannot beleive that I missed not only this thread, but also the original thread!!!

Truly Amazing!!!!

I have to ask, was it just the cache holding you back from the Supervisor on boot?

I have to admit tnt23 this has seriously imspired me to get down and dirty with some verilog!

alexh has provided me with some FPGA's and a devboard, and hell I have more blinkety blinking leds than 100 christmas trees =D

A truly Awe-inspiring project! and its one I do hope that you are proud of!!!

so where are you going to tak it now?

thought about 200pin SODIM ? =D

I'm afraid not on this board, unless you manage to stack a pile of them SDRAM chips on top of each other to get 1GB and then solder enough chipselects to rule them

That's a big problem, to tell erotica from on the internet these days :-P
For the (c) sign, thanks! I was just in a hurry you see

I knew Zetr0 you'd like it

I'll see if I can fit more RAM chips on the board without any serious rerouting or going 4 layers. Also alexh mentioned throwing an AHI compatible card in there, that might be fun (and some Kick kicking and perhaps IDE/SD interfacing, you name it).

Looking at SODIMMs would probably be better then soldering separate memory chips on the board, but it'd depend on the price. I got one 64MB chip for roughly $20, so you can guess what 256M or 512M bank will be.

Should you want to dig Verilog on Amiga, grab the sources at the project's site (http://code.google.com/p/z3sdram/). The schematics and PCB will find their way into the repository soon.

First then there has been a bug with DQM lines, but I think main problem was with not registering (resampling) some input Zorro signals.

Very very nice work....

Truely fantastic project!!!!

It's a Zorro III RAM card for A3000/A4000 computers, carrying up to 64MB of memory. Check the link in the first post for more info.

r6stu · 13 March 2010, 23:12

Will it not work on A2000?

redblade · 14 March 2010, 04:31

Glad there are Electrical Engineers who design new Amiga Hardware

rkauer · 14 March 2010, 06:09

Count me as interested in one board! Even the 64Mb will be more than enough to my Amiga aspirations.

My first Zorro-3 Amiga! Equipped with brand spanking new hardware. Yay!

@r6stu: no. Zorro-2 have 8Mb RAM as the maximum amount. No circumvents for this issue.
