Why this feat was done with ECS instead of AGA is beyond me, sorry...
Apart from this, it looks fantastic.

The AGA chips are probably harder to come by, and aren't they surface mounted for the most part in the 1200 and 4000?

I was wondering, how many people would be interested in getting one of these?
If enough of us are interested, I am sure the pbc boards could be bought at a reasonable price (2-300 us$)

I have an extra dead A1000 that I could steal parts from and would love to get one of these boards.  I know that it also needs parts from other Amiga models (like an A3000 perhaps), but I am sure I could find the other parts somewhere.

If someone finds a PCB manufacturer that can do a small run that is not ungodly expensive, count me in!

I'll take one so long as I can find a super clean A1000 to house it in.

I never had the original 1000 and I would buy this in a heartbeat.

I would easily plunk down $750 for a board.

Georg Braun (gb97816) released an updated version of his selfmade A1000 mainboard.
The latest version includes an extra adressline on the PLD for further 32 bit memory-expansions.
On the upper left side (under the DIN-VGA-Output) you can see a internal connector to feed in a vga-signal from a "undone" internal graphiccard.



Other (allready known) features:
68030/68EC030 @ 50 MHz support
68881/68882 @ 50 MHz support
(successful tested with up to 60MHz !!)
8MB 32 bit fastmem / 0 waitstaits
ECS-Agnus with 2MB ChipMem
ECS-Denise
Amber-FlickerFixer
realtime-clock
1MB flashmemory for drivers and addons
internal ZorroII connector
IDE-connector



There is also a new expansion for his boarddesign .. 2GB CF-Drive for the frontdoor.


Testrun with 60MHz (SysInfo untruly reports 66Mhz).

For more details (and eagle-files) visit Georgs homepage.

I have no experience getting pcb boards done so I wouldn't know where to start... I hope someone who knows more about how to go about doing so can help out at least with advice

I wonder if Acube could be of assistance here.

I doubt it as a number of parts must be harvested from other Amigas in addition to the A1000 I think and most are not installed in a socket, so Acube would have to get these in mass quantities, or have each user that wants a board to find and send to them so they could solder them on to the new mobo.

I don't see how that could work?

[trekiej]

Any chance for a CF card build?
Which is the best way to expand A1000 bus or Zorro2?

[Kristian95]

technically speaking you don't need the front slot cf card adapter as the motherboard has an IDE controller I figure an IDE to CF adapter should work there...

[Nostalgiac]

one question... WHY

I mean... it's not an original A1000
It's not an "improved" amiga...

so.. what is it ? an upgraded mb for an old plastic case ?

sigh... don't we have better things to hope for ?

It is a NEW mother board. that may carry the amiga legacy for another 20 years or so. when all the original amigas are loong gone...
All hail the designer
and hope something like this goes into production anytime soon...

Is there any chance these legacy chips will be replaced so that we don't have to depend on dead Amigas for parts?

[trekiej]

@Fester: I hope some one will make use of some FPGA,s in this area.
I am getting a book on VHDL and have a Xilinx X-board to train myself.

[trekiej]

If all the Rare chips get a socket and the rest soldered or socketed, I believe Acube could help.

[trekiej]

I beseech thee get rid of that barrel battery.

[BlackMonk]

Wasn't Jens reimplementing a bunch of the custom Amiga chips so that people could have replacements?  Or did that fall apart or something?

[trekiej]

I do not know. I hope that Clone-A is still going.
