GBA 1000 board

[trekiej]

Do you think it would be a good trade if I traded my GBA1000 for a working A3000D?

Thanks.

P.S.
It is a blank board.

Good for you, not so good for the other guy.

A Blank GBA1000 for a working A3000D ?

Geezus where did you find the guy, that's like offering $5 for a Ferrari F40.

If you are that comfortable with the offer, take him up on the offer, then buy ANOTHER GBA1000, and use the chips from the A3000D to populate the GBA1000.  Thats one HELL of a cheap way to source the chips needed for the GBA.

Why should he do that? an A1000 can never be as fast as an A3000! right?

It can, if you have the GBA1000, its that new motherboard that was released to the Amiga Community.

It is basically an A1000 Motherboard, with the chipset of an A3000 (it uses the A3000 chips), and according to sysinfo, at *LEAST* twice as fast.  (Cant keep up with a 4000 though.).

so the intent is, to swap a BLANK GBA board for a fully working 3000, then all you do is take the components from the A3000 and solder them to another purchased GBA board and you end up with an A1000 that can at least DOUBLE the speed of an A3000.

    * CPU: Motorola MC68030 at 40 or 50 MHz.
    * FPU: Motorola MC68881 or MC68882 at CPU-speed.
    * RAM: 8 Mbyte 32-bit SRAM, 2 Mbyte ChipRAM.
    * Chipset: ECS Amiga (ECS-Denise 8373 and Fat Agnus 8372/8375).
    * Built-in flicker-fixer with VGA-output.
    * One Zorro-II slot.
    * 1 Mbyte Flash-ROM for optional software.
    * Real-time clock with battery backup.
    * IDE-controller.
    * Two Kickstart-sockets.
    * Fits directly into an original Amiga 1000 case.

(a lot of good information)

Thank you very much for the information. I did come across the GBA1000 while here at amiga.org but did took the wrong impression that it was meant only to replicate the A1000 ... obviously I was wrong! Thank you very much for the information, really appreciated ... maybe one day I might think of such a project.

Pimp the GB A1000 to the max.

My GB A1000, has the fastest 030 CPU Card.
2 MB Chip, 8 MB Sram, 32 MB Dram, 4MB Ramcard in the Frontslot, a special Picasso II Graphiccard, and external USB.

Here is it:

the GBA board is more like a A3000 trying to disguise as A1000. The only thing missing is probably the Zorro 3 bus and the A4000 style CPU accelerator connector.

God that's dead sexy.  Can you requote some of the details from the photos for those of us who don't speak German?

@evillord,

I guess I have not been keeping up with the news for the GBA1000 boards.  I thought that only GB himself had a prototype PicassoII board for the GBA1000?

Has a production run of the pcb's for the PicassoII card been done?  How many exist and where can I get one?

[trekiej]

I do not have a buyer. I just want to find out if the trade would have been worth it.

I do not have the money for an A3000D.
What I really need is a main board for my A3000D case.
Just can not afford it right now.

Thanks.

@Amigadave: GB (Georg Braun) lives only 70 kilometers from me.
I test all his hardware an so i have all the hardware, too.
Only two Picasso II, two 32MB Dram Cards and two Adapter´s for USB (Highway) was made.
The 4MB Ramcard for the frontslot is the only one prototype.
Georg made a 8MB Ramcard (Frontslot) for himself, this is the only one prototype.

I told Georg, we need a A3000/4000 CPU Expansion, but there is no place for it.

Georg made some expansions for the Pheonix Board, AT 2008 clone, 2320 Flickerfixer clone and the Pheonix (68030) Turbocard.

His dream was a selfmade A1000 Motherboard with all expansions on one Board --> the GB A1000.

Here is my Pheonix A1000:
http://www.a1k.org/forum/showthread.php?t=6738

This are very old pics, with the first functions tests.
There is the photo from the Phoenix Turbo II (Prototype).
At first the proto works with 32 MHZ, after any modifications it works with 40 MHZ.

After the Pheonix II Turbocard was a small series made. I´do know how much Pheonix FE Turbocards was made, 10-20?

The card had 4MB 32 Bit Sram.

Georg made only one card with 8MB Sram and 50MHZ. It´s named Turbo Speed. (this was the fastest 030 card for the amiga)

What do you think would be a fair price for an A3000D Mainboard?
I looked at what I paid for the board and would have to say that it was a bad idea. :-D
 I thought I had paid more for the board than I had.
Sorry.
Some one had asked if I wanted to trade for a working A3000D board but he has not responded to my reply.
I am thinking of keeping the board but have not decided.
Cheers.

Lucky you!  I need to get started on my GBA1000 board project.  I have some of the needed parts already.  I wonder if Georg or one of the other builders has a recommended order to install parts from?  I'll go check the forum for the group of builders.
