Oh man, my A600 would *LOVE* that!

Zetr0 · 16 December 2007, 22:49

OMG!!!!!!!! this is just what i am looking for

coze, i thank you so very much!!!!

I wonder if that altera cpld has enough room to generate enough signals for the 68ec020 ? hmmmm

Zetr0 · 16 December 2007, 22:50

FANTASTIC!!! awesome awesome awesome!!!

Charlie · 16 December 2007, 23:21

Bah! First Sputnik and now A600 ram-boards...
...those darn Ruskies!

Paul_s · 16 December 2007, 23:37

I'm seriously going to do the 'pin up' girl sticker on all my Amiga's

keropi · 17 December 2007, 00:09

Awesome!

Shoonay · 17 December 2007, 11:04

@Charlie: and exactly which Sputnik you have in mind? Cause the newest one was made by "our" engineers!

lvd · 17 December 2007, 12:51

Hi!

Beware of us! We are coming =)))))))

Shoonay · 17 December 2007, 12:53

Hello and welcome to EAB!
Drop by, in my place, when passing by, you should!

You can check if it's compatibile with my A600!

coze · 17 December 2007, 13:09

Welcome to our fine boards Lord Vader ! I'm sure Zetro will take pleasure to show you around, but before him I'ld like to show you zetro's fine Musashi Tornado project, which may be of interest to you, and will breath new life into our A600's once completed !

Read a little about it. My board won't work with 14MHz 68000 since it is clocked by cpu clock pin and has very tight memory cycles, with both refresh and access cycles being made during one 68000 bus cycle. Running it at 14Mhz will just overwhelm DRAM chips. My aim was not to delay 68000 cycles, just because it is impossible ($200000-$9FFFFF area is /DTACK'ed by chipset, but bus is floating).
For 14MHz 68000, one must re-invent DRAM controller with wait cycles/whatsoever.

@lord vader

Hello there,

A BIG welcome to this fine forum i call home, there is plenty of mischief to get up to around here

I have read your project with much awe and interest, congratulations on building such a beastie.

I developed a prototpe board based on LS logic but was nearly 4 times as big LOL.. never be able to power it !!!

Currently I have been submerged into the LUCAS project to see if i could add an 020 cpu to the a600 and rework for the a500! we shall see I almost have all the bits

Again your project is indeed inspiring, thank you for joining here!

Chain · 18 December 2007, 07:54

for Zetr0

Where did you get 020s? I have some 68030 in PGA, but not 020...

Is it also on 74LS logic? ;-))))

Merlin · 18 December 2007, 13:50

OMFG!!!

We just HAVE to have the schematics for these babies... I have a couple of A600s just begging to be pimped with goodies like these....

Photon · 18 December 2007, 14:41

Yes, unless either developer sees a market and would like to make money building these, please share schematics...! And if you are the only ones who can get the right components, please share that also.

Amiga (classic) hardware is dead, what we can do is keep it running with newer and newer components that can be bought off the shelf. I believe strongly in this.

Zetr0 · 18 December 2007, 15:01

@Chain

Thank you for the hardware pron... indeed its delicious!!!!

the funny thing is that the pcb electronic prototype i made is actually about that size LOL.. not sure on the physical proto in the pic, but all mine could do was upto 4mb. and to be honest, i am not sure there would be enough juice to power it LOL. I have been looking into replacing those 30pin simms with one 72pin sim, as well as possibly small factor 72pin sim (similar to old laptops) it all comes down to available memory, clearly 72pin is in abundance.

@Lord Vader

Most of the PGA 020's that i found are on ebay, and there over priced IMHO, so i decided to get a small cache' of these ic-china
i have 6 at the moment, i am more than happy to donate a couple for you projects as long as you promise to post hardware pics and hardware pron

Both designs need to take a leaf out of Jen Schoenfeld's book WRT to the mounting screws.

From personal experience I know that if you move your A600 around a lot, without mounting screws, accelerators (and RAM cards) tend to come loose from the PLCC 68k of the A600.
