GBA1000 Order

[PJM]

my understanding is, it has two sockets, one for a KS rom, and one for another KS rom and you can swap between them, so you need a single KS rom set (so not a a1200/a4000 double rom set).

Excellent - a ROM switcher as well.

[PJM]

well, someone with better german should confirm, it says something in the german pdf, its in the rev 00.zip file.

The manual says one socket is a ROM socket and the other EPROM. You can use your own custom kickstarts in the EPROM. In this instance any kickstart chip from the A500/A2000 should work in the ROM socket.

[PJM]

This would be useful. I plan to do a new website to replace the one that was lost .

In studying the schematics between V4 and V5, much is the same when it comes to general Amiga chip set portion of the circuit. Obviously the V5 CPU and memory is radically different than V4 and also the IDE. Braun did a lot of detailed electrical engineering as evidenced by reviewing the eagle files for V4. A ton of work was done, so hats off to him for basically reverse engineering the general Amiga circuit.

I see Braun does not speak too highly of the IDE in the V4 board. This must have been his inspiration to go into an A600 IDE design in V5.

I also compared initial board release schematics with V4. Various small changes were made, but overall it is quite the same.

One other thought comes to mind...That being a small hacker board containing clock ports being added to a V4 board. Might be possible, thus giving the V4 a nice feature boost w/ 3rd party add ons. (Subway USB, Delfina, ?) Maybe someone clever can work on something along these lines?

I am confused by Kickstart version. The V4 looks to be a straight up 2MB based ECS design to me so one would assume that 3.1 Kickstarts would be a possibility.

The board now takes both of the ECS 2mb Agnus chips (A500+/A3000). The board can run kickstart 3.1 with no issues or your own customised kickstarts. A clockport could be added, there's a couple of places it could be taken from. His schematics are fantastic. You could build your own Amiga design with them. The A600 IDE design is far better, as used in a number of A500 expansions. In the future I do plan to adapt them to ATX for my own purposes.

[PJM]

is the parts list different from v0 to v4? ie: the spreadsheet in the a1kboard_00.zip is valid for v4?? if you have the v4 files, can you release the spreadsheet?

The spreadsheet in there appears to be good for v4.

As for the GBA1000. Do not forget the board is based on the Phoneix and several expansions that Braun added to form a new design. The schematics for the most part are nothing new, it's several AMIGAs effectively hashed together and held together by Brauns magic and workarouds including the ide controller. It's the board layout/design that is unique. Brauns schematics are easier to read than the Amiga equivalents, this is the point I was trying to make.

[PJM]

the schematics are great, yes. but the spreadsheet tells me I need X count of resister Z, Y count of 74x chip etc. otherwise I have to go over the schematic and try and count each one individually.

the phoenix board was great, we saw quite a few, since they were locally made/designed.

The second part was me answering billit not you sorry. I forgot to requote. I fully understand why you want the spreadsheet .

[PJM]

Significant changes will require a lot of engineering, hence for an immediate result, use Braun's V4 as is.

Regarding PCI...A new design in 68060 combined with PLX9054 chip is far superior to anything currently employed on Amiga. Reference the R Czuba designs made for Atari (CT60. CTPCI). Big engineering required to get this into Amiga. Even adapting AGA into the equation will require a bit of effort. Hence I remain content for now with the Braun V4. Not that I wouldn't like these other possibilities in the future however...

Theres actually a now open-sourced AMIGA 4000 PCI expansion so it wouldn't be that difficult if based around the hardware from that. But thats not the point as this thread is about the GBA1000.

[PJM]

Idea: Make a board where any Agnus type of chip can be used ie OCS/ECS/AGA, same for CPU such that it can use 68000/020/030/040/060, and other periphial chips like Paula etc.

Such that any combination can be used depending on what chips can be found from otherwise "dead" motherboards. So if you find a working AGA on one motherboard, 68000 from a second, and Paula from a third.

Practical design would be multiple PCB pads. And possible configuration with jumpers. Ie use the ones you can populate. So that no scrap motherboard components would be wasted.

Nice idea - but you couldn't have a motherboard with AGA and ECS support. Its one or the other. The OCS/ECS is possible with this board to some extent. Don't forget the chip packages are so different across some of the models.

I opened the project in eagle and generated parts list in which creates qunataties etc
eagle didnt like some names so it added a @ after some devices.

this may help some people

Do you mind joining eab if you arn't already a member and visiting this thread:

http://eab.abime.net/showthread.php?t=67619 and posting that list perhaps?

[PJM]

OK, it's time for a stupid question: What about FPGA? I assume it's not possible or somebody would have suggested it by now... but I don't mind playing the fool and asking.

If you want the FPGA route then your better off with the minimig, natami or fpga arcade. This board is about the real hardware .

[PJM]

Oh.. Are there any plans to kinda merge the component order I see going down on eab.abime.net?  I see a group order forming there for the CPU's and sockets.

For the larger more expensive components yes. The easier to get bits there's little point but we'll see what develops.

[PJM]

First post updated with a pre order by the Feb 24th and pay by the 3rd of March.

[PJM]

Pre-order is payed to kipper, is that correct?

Yes he got a good quote on the pcbs. When he's ready to take the money ill post details.
