Wicher 508i came into being as a universal solution for users looking for highly-clocked MC68000/MC68010 classic Amiga CPUs. Stable configurations running at 50 MHz have been confirmed when paired with MC68HC000 series chip. Unfortunately, not every unit is capable of performing at this clock speeds over longer periods of time.

Wicher 508i allows expanding Amiga 500 RAM upto 11MB. It also provides a necessary interfaces for connecting 2,5” IDE hard drive and I2CI bus devices. A CPU Motorola MC68HC000FN20 20Mhz (nominal frequency) is availabe as option on this page.


  • AmigaA500/A500+ compatibility (in place of the original CPU).
  • PLCC68-packaged MC68000, MC68HC000, MC68010 chip support.
  • recommended chip version: MC68HC000 (not included, available as option).
  • recommended Kickstart version: Kickstart 3.1.
  • supported CPU clock speeds: 7, 25, 50 MHz.
  • RAM memory: 16MB (AmigaOS can use just 11MB).
  • Amiga A600-compatible IDE controller (Kickstart >= v2.05 [37.350] is required).
  • I2C Bus controller.

  • Amiga 500 (Custom Kickstart 3.1, MC68HC000FN16 16Mhz CPU running @50MHz, scsi.device V46.0)
  • MIPS: ~4.43
  • Dhrystones: ~4245
  • IDE transfer speeds: ~3.1MB/s (using IdeFix97 ~5.8MB/s)
  • RAM transfer speeds: ~6.99MB/s
  • The above results have been achieved with SysInfo 4.0, AIBB 6.5


  • This software lets you to configure Wicher's init options via CLI command or the WicherBootMenu module, allowing creation of custom Kickstart versions (with Remus program). WicherBootMenu can be accessed by holding down the left mouse button when turning on or rebooting your Amiga.
