Wicher 508i accelerator

Wicher 508i turbo card has been designed to be installed inside Amiga 500/500+. It supports 68000/10 CPUs, up to 11MB of Fast RAM and IDE 2,5”/CF adapters hard drives. Also provides a I2C bus. CPU clock speed can be set up to 50 MHz. A CPU Motorola MC68HC000FN20 20Mhz (nominal) is available as option.

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.

Features:

  • 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.
 
SysInfo Benchmarks   Wicher Startup Control   Wicher Boot Menu   Wicher CLI commands


Benchmarks:

  • 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


Software:

  • 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).

Available options:

  • MC68HC000FN20 20Mhz (nominal frequency).
  • Printed manual.
