Deniser: Open Source replacement for Denise chip On GitHub, Martin 'endofexclusive' Åberg has established a resposity called 'Deniser' for building and programming a Denise chip replacement. Denise is the Amiga custom chip responsible for most of the graphic related tasks such as bitplane display, palette registers, smooth scrolling, hardware sprites, flexible screen object priority, collision detection and more. In the Amiga, Denise operates in concert with the Agnus and Paula. Schematic, BOM and more information can be found in a separate PDF file. Status of the project:

Developer log: This Week in PiStorm 2021-08-15 In his weekly column 'This week in PiStorm' the developer Andrew Hutchings summarizes the latest progresses on the 'PiStorm' project. In his latest entry among others he has reported, that Claude Schwarz has started developing an Amiga 1200 version of PiStorm. It is supposed to be based on a Pi Compute Module 4. Furthermore the support of the Emu68 emulator for PiStorm was continued. It "boots DiagROM and is mostly all the way to booting kickstart." (dr) [News message: 17.

Accelerator board: Returning the Buffees for rework In the middle of June the developers reported that a second batch of 60 beta Buffees was ordered which now arrived. They "managed to power them up." However, new problems were found, as the developers further report: "While we did manage to boot them up and verify that some of the issues we had with the alpha were fixed, we also managed to introduce a couple of more. And a third issue that doesn’t really hurt us too much, but it is a pain:
We’ve made excelent progress on Buffee despite all these set backs and have developed a new method of handing the weird world of the variable length 68000 instruction and it’s dasterdly sidekick, the extended addressing mode. This has been the one last issue with PJIT that I had yet to solve. The current method was to bake in the complex decode logic into every instruction that uses it – and for an addressing mode that’s not nearly as often used as say register direct or simple load/store operations, it was eating up a huge amount of the code base, since the “inline” nature of PJIT meant copying the same 20-30 ARM instructions for each opcode. Not efficient! And not fast either, the instruction routinely had to dig back into 68K memory and to do that, it would need to compute the 68K program code since we don’t always track it and … well, it was a mess. So of course the answer was staring me in the face all the time. Our old model shows all these NOP’s filling the operand-gaps between opcodes – so why not simply shuffle them around and have all the literals and extended addressing modes get handled BEFORE we execute the actual instruction. Most 68000 opcodes are a single word and PJIT must either compile these to a single, inline ARM instruction or branch to a subroutine to handle more complex operations. But there are many 68000 opcodes that take considerably more than one word and PJIT can handle these by having special operators for each word within the whole instruction." (dr) [News message: 17.
