Built into the old IBM case is a C64E motherboard (the new, short board) from a late C64 C and a much older 1541 disk drive. Basically the machine is an original hardware setup – including the original power supplies. The C64 motherboard is mounted horizontally at he bottom of the case. The C64 PSU is attached to the flank of the case – not very discreet I know. The drive mechanics of the bulky 1541 drive fit perfectly to one of the 5 1/4″ drive bays. The motherboard (or logic board) and transformer have been relocated around the mechanics.
An external power cord plugs into the rear of the machine. The mains voltage is routed to the original transformers trough a two-stage switch and fuses. The two stage switch makes it possible to power the C64 without starting up the disk drive and also to switch off the 1541 while C64 remains on.
The obvious issue of keyboard was also solved in a rather straightforward manner. The keyboard ribbon was simply cut, and then wired to the PC’s serial port connector at the back of the machine. An extension cable for the keyboard was done from old printer cable, which then plugs into the port. Not pretty but does its job!
The other necessary connectors were also routed to the back of the machine. A composite video, dual mono audio and RF antenna connections were routed to the added back plate of the machine using RCA plugs. The transparent back plate is in place of the missing PC PSU. Joystick ports are available at the bottom, as the motherboard barely fits inside the case.
The C64 and 1541 use the case’s power and HDD LEDs as their power LEDs. The power button of the case acts as a reset button for the C64. Read the rest of this entry »
