SuperCard+ for the Commodore 1541, 1541-II, or 1571 disk drive. For use in a 1571 disk drive you would need to attach a wire from the SuperCard+ board to pin 23 of the 1571's CIA chip. This is the ultimate hardware for copying protected disks. Commonly referred to as the 'ribbon cable' version, this device was designed for the 1571 originally (with the required wire) but it also works in the 1541-II and the 1540 or 1541 without any wires. Installation information for all drives is contained on side 2 of disk 1. Soldering is required for 1571 installation and may be required for other drives if the 6502 (CPU) does not already have a socket.These are BRAND NEW, never installed or used. These are not knock-offs that were found on , sold by people from overseas. These are the genuine SuperCard+ boards manufactured by Utilities Unlimited or Oregon, Inc. How do I know? I was co-owner of the company, and the person responsible for developing all of the products that came from U.U.I. I have thousands of pieces of inventory from this company that are being saleed off!I will include a set of the latest SuperCard+ (v6) disks with the sale. I can also include .d64 images of these disks via a file if requested.These boards provide 8K of extra RAM for the disk drive, so they can be used with any programs that took advantage of the additional RAM, such as Maverick, Renegade, Copy ][ 64/128 v4.x, and others. RAM is located at $6000.These were the final version of the SuperCard+ boards and never released to the public. The EPROM is the final version designed for the v7.0 software (which was never released). The RAM chips are also faster. At some point, I may release the v7.0 software. The v6.0 software included are produced new, with 3 sides (2 disks) total. These disks and documentation can also be downloaded from my website: www.cbmstuff.comShipping fee is a flat rate via USPS priority mail w/delivery confirmation. I will combine domestic shipping costs on up to 6 items purchased from my sales. So, for the same price of $5.35 you can get 6 items delivered to you in the same box... that's potentially less than $1.00 per item for 2-3 day USPS shipping! I ship world-wide using USPS International Priority (shipping costs calculated at checkout).I accept Paypal only! Thank you for looking at my sales!
