Jan 5, 2024 · My personal experience is that the Rev.5 NTSC board is the most tricky one to get working right, but that might have been the special sample I have with a 8370 NTSC OCS Agnus. It was my first "hard nut to crack" during ACA500plus development, and it was the final nail in the coffin of "make it work with a synchronous clock".

Apr 1, 2022 · Hello, I'm using a socket for a FPU 68882 at A1200 mainboard (U0). Without accelerator and with FastRam ACA1211 the OS detect FPU. However if ACA1221lc accelerator is used, then the FPU is not recognized. Do you have any idea how to fix it, so I can…

Oct 29, 2024 · The one thing that I have kept secret all over the development time is that the FPGA is wired up in a way that it can halt the 68040/68060 CPU, but also keep the CPU of the host computer off the bus. In that state, the FPGA takes over …

May 8, 2021 · In the A4000D computer, J214 gets in the way. It needs to be bent aside before the flicker fixer can be installed. The pictures show how far it needs to be bent, so anyone who wants to buy can judge before buying if he's willing to do that. The jumper has been put there by Commodore in preparation for a new chip set that never saw the light of day.

Nov 8, 2024 · Hi, I recently installed my Indivision AGA MK3 into my Amiga CD32. All works well except for when it has been running for 30+ minutes. The video output remains stable, the Live mode functions as expected but saving any changes to the Configuration via…

Feb 11, 2022 · Hello, nice to greet you. I wanted to make an inquiry. I was thinking of purchasing the ACA1234 upgrade. I have an ACA1234 at 33mhz and I was thinking of taking it towards the value of 50mhz. Before starting to carry out the tests that the ACATOOL…

Jan 13, 2024 · The flicker fixer is not connected to any part of the CPU/RAM subsystem of the computer, so technically, it does not have any means of making the CPU crash. We therefore need to dig deeper to find the root cause of your problem. If the computer crashes, it may *seemingly* be caused by the flickerfixer, but it may still be a power problem.

Apr 30, 2022 · Wow! Ok, will drill deeper into mmu configuration docs and see if I can manually edit this. Note I re-installed 3.2.1 on top of a clean 3.1 without mmu libs installed, this time taking special care to install the mmu disk from Hyperion with the special A3000 modules.

Jun 12, 2024 · Yes. 256 colours out of 21 bits colour (=2 million colours, not the 4096 that you know from OCS/ECS), 1024x768 and 1280x1024 pixels is the development target that you can see in the first post of this thread.
