In another thread I mooted a separate thread to maybe find out just how many 65816 systems there are, so I'll start with what I know:

Older, commercial systems:

  • Acorn Communicator - 1985
  • Apple IIgs - 1986
  • Super Nintendo entertainment System (SNES) 1990

Modern ones in no particular order:

  • BDD's PoC - under development.
  • Gordon/Drogon's Ruby 816
  • Neon 816 - dead end
  • Foenix - various versions - several made and sold, project moving onto other CPUs

And what else? Please add, update, correct mistakes, etc.



-Gordon

Good start... as I'm mostly unaware of the '816 systems.

However, would the WDC W65C816SXB being currently sold count as an '816 system?

Only two or three of these look like they are mature, but since you included a WIP in your list some of these may qualify:

I'll add my projects:

- a 6502 replacement/accelerator card http://www.6502.org/users/andre/pet816/index.html
- my CS/A computer with a 65816 CPU card http://www.6502.org/users/andre/csa/cpu816v2/index.html
- the MicroPET Commodore PET replica http://www.6502.org/users/andre/upet/index.html

An older commercial system famous in the Commodore community is the SuperCPU, a 20MHz accelerator for the C64.

Other 65C816 units:


My POC V1 series now consists of four working units: V1.0, V1.1, V1.2 (first one to reach 20 MHz) and V1.3. Hardware design in all of them is stable at this point, so technically none is under development. No further design work on the V1 series is planned.

POC V2.0 is awaiting final assembly, testing and debugging, so it would qualify as "under development."

Nice thread!

I would mention Beeb816, an in-socket upgrade for the BBC Micro and other Acorn machines, not entirely unlike the idea behind SuperCPU and UltraWarp already mentioned, and perhaps the Transwarp with '802 upgrade.

Another work-in-progress is Dominic Beesley's blitter project which has all sorts of possibilities including a 65816 running BBC Basic.

I'm working on one as well:

https://github.com/jmstein7/soft_65c816_core_SoC_23LC512

Jonathan

Code:
This project comprises a 65c816 Soft Core SoC with Serial SRAM Driver (23LC512) and XMODEM Bootloader to load your programs into RAM from a PC via a terminal program. The target here is a Xilinx Arty A7, using a soft 65c816 core, with block memory for the RAM and ROM, though the design has an additional 64k of serial SRAM mapped from 0x10000-0x20000.

Bitbucket require you to accept cookies, turn off adblockers and jump through various other shenanigans just to see their advert ridden content. That's the price to pay for free hosting these days.

I get a blank page in my regular browser, but see it just fine with a sandboxed browser allowing all cookies by default, adverts allowed, canvas data extraction, selling my soul and everything else.
