Ultimate64 Elite - Flash Rom Files

Flash ROM Files

Due restrictions the Ultimate64 Elite board come without kernal, basic and chargen rom files. So at first startup you have to flash it from USB stick (the files can be found in e.g. VICE emulator C64 folder).

Needed files:

  • basic
  • chargen
  • kernal
Add file extension ".rom" or ".bin" and copy it to the USB stick.

Turn on the device, choose the USB stick, navigate to the files and select each ROM and run "Flash as Orig. ... ROM".

Guide can also be found here.

Amiga 1000 PSU recap

If you have stability issues with your 34 years old Amiga 1000 it's a very good idea to check the output lines of the power supply: +12V,-5V and +5V! Plug pinout: Check with scope to also see ripple and noise or rough with a multimeter!                    Current Voltage      Min.    Max.             Stability        Ripple & Noise ------------------------------------------------------------------------------ +5V            2A         8A               +/- 5%           150 mV P-P +12V          0A         1A               +/- 5%           150 mV P-P -5V             0A          0.25A         +/- 5%           150 mV P-P When it comes out that the output values are too bad you have to replace the old capacitors of the PSU! For this you must disassemble the whole computer due the position of the power supply: I have the Shindengen CA1000PS/EC (PAL Version)!
