Commodore/MOS 6510/8500 to 7501/8501 CPU Adapter PCB/Module [C16 Plus/4 C116]

Description: Foreword This printed circuit board (PCB) implements the MOS 6510/8500 CPU adapter circuit for Commodore computers that use a MOS 7501/8501 CPU, designed by Andrew Challis. Please consider supporting Andrew's work and purchasing from him if possible; his eBay listings and website are listed below. https://www.ebay.co.uk/sch/hackjunkcom/m.html http://hackjunk.com/2017/06/23/commodore-16-plus-4-8501-to-6510-cpu-conversion/I am offering this listing to improve on delivery time and costs for residents of the United States of America, when compared with other listings available to only the United Kingdom. If you live outside of the United States of America, the shipment for this listing is processed through the eBay Global Shipping Program.If you are unfamiliar with how this adapter works or its limitations, please review Andrew Challis' website linked above. Overview This listing is for one (1) fully assembled CPU adapter module. The 6510/8500 CPU is NOT included. The optional modified kernal EPROM is NOT included. The socket for the 6510 is of the machined/precision variety, as are the round male header pins (for insertion to the main board). I have verified that these round pins will install into both the single-wipe and double-wipe socket; the factory-installed socket is likely of single-wipe variety.The photos in this listing depict the fully assembled module, a bare PCB, and an example of a fully assembled module with 6510 CPU inside of a Commodore 16 computer. All solder joints have been inspected for tidiness and cleaned of excessive flux, and the module was tested by ensuring proper continuity between all male and female pins.Furthermore, this module has been modified from a previous version to be smaller, and to also include breakout pads/pins for the A14 and A15 address lines. These two address lines are often connected to 64KB Commodore 16 memory expansion projects.PCB Dimensions: Approximately 59.5mm x 20.8 mm Overhead: Approximately 10mm from top of 6510 socket to male pin-header mating surface (black plastic above pins) Brief demonstration and video overview of the adapter PCB: https://youtu.be/q8fJ7YQBNzsCombined shipping is available for multiple purchases. InstallationEach of the computers in the Commodore-264 series (16, Plus/4, 116) has different clearance between the system board and the bottom of the keyboard, so please evaluate your situation carefully prior to purchase. I have only verified this adapter to install to the factory CPU socket of a Commodore 16, with a 6510 CPU installed in the socket of the adapter PCB. In this configuration, the RF shield makes contact with the top of the 6510 CPU. It should install into a Plus/4 or 116 by removing the factory installed CPU socket on the system board (noted on Andrew Challis' web site above); please verify with above dimensions prior to purchase.
