GIVING NEW LIFE TO AN OLD FRIEND There's a been a resurgence of the 8-bit Commodore 64 computer over the last few years. There's a lot of great programs & games that were created for the Commodore 64 computer and with the help of some technological advancements, avid Commodore owners can relive the enjoyment and excitement of the Commodore 64. Despite being a great little computer for its day, one of the biggest problems with the Commodore 64, was the power supply. Originally, the power supplies were repairable and had a ventilated case. The design was later changed to what is referred to as a "solid brick" design, where the internal circuitry is "potted" or filled with epoxy, making it completely unserviceable. The "brick" power supplies were well known for going bad and blowing out the RAM and other chips in the Commodore 64. The supply didn't include a power switch, so even when the Commodore 64 was turned off, the supply was still running. It also was pushed to its limits with add-on Accessories. The epoxy prevented the supply from adequately dissipating the heat from the supply causing component failure. In the early 80's, BBS Sysops (Bulletin Board System, System Operators) asked me to design a rugged alternate power supply for the Commodore 64. These BBS systems operated 24/7, causing the factory supply to eventually overheat and damage the computer. So by demand, we designed the heavy duty "Cylonsoft Electronics PS-1". Features: Fully compatible with the factory power supply Well ventillated and fully serviceable Fuse protected (2A 5x20mm AC input fuse - user replaceable) AC overvoltage protection (MOV) Current/power limiting & thermal shut-down protection On/off power switch Power indicator Output regulator is thermally heatsinked to the enclosure for cool operation Non-skid rubber feet Standard 6' power cord w/3-prong grounded plug (AC input) 7-pin circular DIN plug w/5' cable (to C64) Holographic serialization label Proudly designed & built in the USA Electrical Specifications: AC Input: 120VAC @ 60Hz DC Output: +5VDC @ 3.0Amps AC Output: 9VAC @ 2.0Amps Dimensions: 5.25" (133.4mm) wide x 3.1" (78.74mm) high x 6.0" (152.4mm) deep Weight: 5.0 lbs (2.27 kg) Warranty: 1 Year The PS-1 was a very reliable power supply for the Commodore 64. We've never had a single failure during the entire time that we were into production. In fact, we've NEVER had a single failure! What we really didn't realize was that many of these BBS systems switched over from landline access to access via the Internet. As a result of advancements in technology, accessories are now available to add an ethernet port to the Commodore 64, as well as a fully 1541 compatible drive that uses USB stick memory rather than magnetic media. These advancements allow die-hard Commodore fans to copy their programs and games from 5-1/4 floppy disks to USB memory, making it possible for a single USB stick to hold the data from many floppy disks. So, we've been asked again if we would bring the PS-1 back.... and we have! but it is now the SHARCNET-USA CPS-64 (Commodore Power Supply-64). So, if you need a very sturdy & reliable power supply for 24/7 operation or need a power supply to replace an original supply that has failed, we highly recommend the CPS-64. The CPS-64 can be ordered directly from us for only $34.99 USD + $13.45 USD shipping (includes $50.00 USD insurance) within the US via PayPal. We accept all major credit cards via PayPal.
