Wicher 500i rev 2c (the newest) Turbo Card for Amiga 500/500+ with very fast IDE.
Wicher 500i rev.2c turbo card has been designed for installation inside Amiga A500/A500+ computer. It supports 68000/68010 CPUs (using PLCC68 package), up to 12 MB of Fast RAM (using 16-128MB standard SIMM72 memory modules) and IDE 2,5” hard drives. CPU clock speed can be set up to 50 MHz. 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 1-128 MB 50/60 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).
AmigaA500/A500+ compatibility (in place of the original CPU),
PLCC68-packaged MC68000, MC68HC000, MC68010 chip support,
recommended chip version: MC68HC000
recommended Kickstart version: Kickstart 3.1, s
upported CPU clock speeds: 7,12,14,16,25,28,33,42,50 MHz (originally set to 25 MHz)
RAM expansion: industry standard SIMM72 (FPM/EDO) 1-8MB or 16-128MB, 50/60ns memory modules up to 12 MB FAST RAM,
Amiga A600-compatible IDE controller,
Amiga 500 (Custom Kickstart 3.1, MC68HC000FN16 CPU running @50MHz, scsi.device V46.0, MAPROM function enabled)
IDE transfer speeds: ~6.3MB/s (using IdeFix97 ~6.7MB/s)
RAM transfer speeds: ~7.02MB/s
The above results have been achieved with SysInfo 4.0, AIBB 6.5
The provided software facilitates user-inititated configuration changes via CLI command or additional 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:

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 12-28 MHz clock speeds. However, not every unit will operate without errors at 33-50 MHz clock speeds.
