A HC508 Amiga 500 accelerator card project from mc68k:

 Finally, the project has reached a stage when complete system tests are possible The integrated CF + IDE allows running the complete OS 3.1 with WHDLoad.
Key feaures:

  • 68HC000 CPU running at 50 MHz (100% MC68000 compatibility)
  • 40 pin IDE connector for HDD, CD ROM etc.
  • Integrated CF connector
  • 8 MB Fast RAM (1 wait state)
  • 512k FlashROM for Kickstart (1 wait state)
  • Utility for disabling / enabling every module separately (XCPU, XRAM, XROM, IDE)

Project info at Amiga projects blog.

  • Drone: So these go for around $330 USD and NO published calibration procedure online or otherwise? Given what's inside - I don't think I'll be considering...
  • Pekka Akselin: This is ridiculous!? :-) We are back at 256(!) byte EPROMs that needed multiple, a handful, of voltages to run! :-(
  • KH: Let's try a back-of-envelope calc balancing energies. From MCP1700 datasheet, there are graphs for a 200mA load step. Estimate the energy shortfall as 12uJ. Say...
  • Daniel: It's been a week and my comment is still awaiting moderation. Apparently the CIA doesn't want their involvement known?
  • KH: Agree, so okay, I guess he must have learned from somewhere. 100nF and 1000uF is so far apart, that was jarring; it's more magic incantation...
