Wicher 500i accelerator

Re-stock: September 2019 (delayed). Rev 2c. Wicher 500i turbo card has been designed to be installed inside Amiga 500/500+. It supports 68000/10 CPUs, up to 8MB of Fast RAM (using standard SIMM72 memory modules) and IDE 2,5”/CF adapters hard drives. CPU clock speed can be set up to 50 MHz. A CPU Motorola MC68HC000FN20 20Mhz (nominal) and a 8MB 72pin SIMM module are available as option.

Wicher 500i 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.

Our product allows expanding Amiga’s RAM with standard 1/2/4/8MB 60 ns SIMM72 FPM/EDO memory modules. It also provides a necessary interfaces for connecting 2,5” IDE hard drive and SPI bus-equipped modules (e.g. RTC, Ethernet). A CPU Motorola MC68HC000FN20 20Mhz (nominal frequency) and a 8MB 72pin SIMM module are available 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: 12,14,16,25,28,42,48,50 MHz,
  • RAM expansion: industry standard SIMM72 (FPM/EDO) 1-8MB, 60ns memory modules (not included, available as option),
  • Amiga A600-compatible IDE controller,
  • SPI controller
SysInfo Benchmarks   Wicher Startup Control   Wicher Boot Menu   Wicher CLI commands


  • 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.

Wicher, list of options:

  • VERSION - display version information 
  • STATUS - display actual Wicher config 
  • LOAD - load config from a file 
  • SAVE - save config to a file 
  • CLK - change CPU clock speed 
  • FASTMEM - (on/off) enables/disables FAST RAM 
  • CFGRAM - automatic configuration of memory controller 
  • IDE - (on/off) enables/disables IDE controller 
  • SPI - (on/off) enables/disables SPI controller 
  • RAS13 - (on/off) enables/disables support for additional memory banks in the SIMM module (two-sided modules)
  • BIGRAM - (on/off) enables/disables support for SIMM module 16MB-128MB (experimental function)

* Example: wicher clk=28 RAS13=on

Please note: Not every CPU unit remains stable when overclocked (i.e. clocked with higher speeds than the one prescribed by its manufacturer).

Most SIMM72 memory modules should function correctly at 12-25 MHz clock speeds. However, not every unit will operate without errors from 25Mhz to 50Mhz on all A500 systems. We warranted our SIMM modules (available as option) will works upto 25 Mhz clock speeds.

Available options:

  • MC68HC000FN20 20Mhz (nominal frequency).
  • Printed manual.
  • Memory: 8MB 72pin SIMM module.

Warranty: 2 years.
