Doctor V64 - Specifications

Specifications

• CD-ROM access speed: Most early V64 models shipped with a standard IDE 8X CD-ROM . During the manufacturing lifetime of the device, latter V64 models shipped with 16X and eventually 20X drives. V64 units could be purchased without a CD-ROM drive. It is possible to replace the unit with a faster IDE CD-ROM unit (such as the 52X model in the image on this page).
• Many DrV64s shipped internationally were ordered without an installed CD-ROM drive, to save on shipping costs associated with weight, import duty on the drive and the ever increasing speeds of drives available. While theoretically a benefit in the user being able to use their own faster/cheaper drive, the variance in power draw of different manufacturers drives at different speeds caused issues with discs spin-ups up exceeding the wattage rating of the included Bung PSU. This led to users swapping out the Bung PSU for a more powerful model, or selecting low draw drives (mainly Panasonic drives sometimes badged as Creative).
• CD-Media: V64s can read CD-Rs and CD-RWs (provided the installed CD-ROM unit supports rewritable media). Supported media has to be recorded in Mode 1, ISO 9660 format. Doctor V64s only supports the 8.3 DOS naming convention. Joliet file system is not supported.
• RAM: 128 megabits (16 MB) or 256 megabits (32 MB). Original V64 units shipped with 128 megabits of RAM. V64 units started shipping with 256 megabits when developers started using bigger sized memory carts for their games. Users of the time had the option of buying a memory upgrade from Bung and other re-sellers.
• Power supply: The Doctor V64 uses a 4 Pin MiniDIN jack (as used for S-Video) for connecting the power supply cord. Power supplies included with Doctor V64s were very unreliable. Bung replaced the power supply with a sturdier version in later V64 units. Replacing broken power supplies became one of the most common maintenance problems with the V64. It is possible to modify an AT PC power supply for V64 use.
