Commodore C16 expanded to 64k (so PLUS4 games can also run on it...), modified with JiffyDOS (selectable).
The motherboard modification also integrates protections to improve static electricity resistance on the joystick ports (protecting the TED) and the cassette/disc ports (protecting the CPU) greatly extending their life expectancy.
The basic ROM, kernel ROM and PLA are replaced with modern chips that require less power (hence generate less heat) and are more reliability.
The selection between CBMdos/JYFFYdos is done via a button near the RF video output (no holes have been made on the case).
Power supply AC-DC added!
Console only: no power supply, cables, joystick, tape unit, monitor...
149€ 139€ 129€ + shipping + (eventual) PP fees
Inside it:
1) Jiffydos; a simple dual-kernal with a well-placed switch (no holes on the chassis)
2) a"JUGGLER" multimod, it implement:
2A) 16/64k RAM expansion based always on static RAM
2B) CPU replacement (a specific revision of CPU4C16 project) based on N-Mos 6502"A+" core (on Amibay) (an independent CPU4C16 test)
2C) The task of the "input keyboard/joystick port" (normally done byTED chip) is synthesized on board, so the C16 will work fine even if the TED used has problems with its port (LATCH problem: mixing the two signals of the joystick, reading the keyboard ...)
"The TED port can be easily damaged by ESD by plugging / unplugging the joysticks,
as the CPU port can be damaged by ESD plugging / unplugging the external drive (tape / disk) even if the devices are turned off!
On the CPU4C16/Juggler the CPU port is synthesized by CPLD so the N-Mos CPU core cannot be reached by the discharges of the external pins,
and on Juggler the same is for the TED port!"

Edit: Power supply AC-DC added!
