AA3000 on A1K forum - the AGA A3000
I’m surprised no one’s reported on this so far, it’s pretty big news!
https://www.a1k.org/forum/showthread.php?t=66906 Scrat and Matze got hold of some of the few remaining AA3000 development boards, populated them and now have working AGA A3000s. Bonkers |

Was that the one with or without the DSP?

With. But they haven't fitted one of those yet.

Did it have any chips which cannot be sourced? Like the Amber 2?

no Amber on this board - no flicker fixer at all (the new AA-modes were supposed to render this unnecessary, but did not fulfill the promise as we all know now)
The chip that can not be sourced is the AT&T DSP along with its own real-time operating system, that was supposed to be accessible via new libraries from AmigaOS... |

It might be more interesting to know if there was supposed to be a boot ROM to go with it? (All these C= source leaks, isn't there anything from the DSP project somewhere?) |

Very cool. I personally wouldn't go through the trouble of hunting down the DSP though. :-)

better check the embedded stuff etc
might be able to use the DSP32C these were used in telephone equipment etc aka embedded markets stuff In the early to mid-1990s, there were several other DSP-based designs that were quite possibly inspired by the ACPA and/or Mwave. These included the AT&T VCOS/RoadRunner (AT&T DSP3210), Cardinal Technologies DSP and Adaptec AudioEdge boards (Analog Devices ADSP-2115), or Sierra Semiconductor Aria chip set (Texas Instruments TMS320C25, the same DSP the ACPA used).

They should reverse engineer the boards to make new ones!

DSP32C, DSP32xx: 32-bit floating point with 40-bits accumulator and 16/24-bit fixed point. The 32C has three 512 x 32-bit RAMs, while the 3210 has two 1k x 32-bit RAMs and a 256x32-bit boot ROM. 32C: Serial and parallel I/O, 3210: Serial I/O, timer, DMA-controller. 3210 available at 50 and 66MHz i would check into lucent telephony stuff eg stuff like this https://www.ebay.com/itm/Avaya-Lucen...wAAOSwBdhbT-J1 https://www.ebay.com/itm/Used-Good-C...ry!33702!US!-1 has a dsp32c and 3270 https://www.edn.com/Home/PrintView?c...ItemId=4352143 DSP32C-50 MHz; 225 mA typ at 5V; 1024x32-bit RAM; 4kx32-bit ROM; 24-bit external addressing; programmable wait states (0 to 3); two DMA channels; synchronous serial port, 16-bit parallel port; no timer; 133-pin PGA/164-pin BQFP (bumpered quad flatpack). $70/$57 (10,000). DSP3207-55/66 MHz; 150/282 mA typ at 3.3V; 2kx32-bit RAM; 256x32-bit boot ROM; 32-bit external addressing; programmable wait states (0 to 3); two DMA channels; 32-bit timer; general-purpose, 8-bit I/O port; 132-pin BQFP. $37/$42 (25,000). DSP3210-55/66 MHz; 220/285 mA typ at 5V; 2kx32-bit RAM; 256x32-bit boot ROM; 32-bit external addressing; programmable wait states (0 to 3); two DMA channels; 32-bit timer; synchronous serial port, 16-bit parallel port; general-purpose, 8-bit I/O port; 132-pin BQFP. $42 (10,000).

I doubt that any "C" variant would work, or anything other than the DSP3210:
The DSP on the board shares the same processor-bus with the 030 and the 882 and using FastRAM. But even If you find the right chip: it would just be sitting there, doing nothing at all. |

but if you cant get the 1 chip why not get something better that might be available so that way if anyone ever does do anything it would be faster |

The only way the DSP would be worthwhile is if a DSP solution for other Amigas could be designed. It could perhaps be interfaced with the clockport.

Bummer - The A1K forums are saying they are not taking new registrations - And I can't view the forums with the article on it. Is it invitation only?

I wonder can we emulate it via WinUAE? I supposed an A4000 with 030 and SCSI setup would be as close as possible? Just fantastic news for everyone.
