The -RC model reduces the total part count of the SBC6120/FP6120 combination, eliminates some of the parts which had become difficult to find, uses a simplified front panel construction with commonly available switches, and is both significantly cheaper and easier to assemble than the original SBC6120/FP6120. The -RC version has a functionally identical front panel to the FP6120, uses the same firmware (and indeed the same EPROMs) as the SBC6120, is still able to run OS/8 and any other software that would have run on the SBC6120. The -RC also has a dedicated spot for attaching a [http://www.sparetimegizmos.com/Hardware/VT.htm VT6 terminal] board which allows it to connect directly to a VGA monitor and PS/2 keyboard. There are already extensive PDF manuals online for the original SBC6120 and FP6120 front panel and much of the -RC functions, including the operation of the front panel and the built firmware reference, will be the same. This collection of wiki pages documents the aspects of the -RC which are unique to that model. It is Spare Time Gizmos first foray into user supplied community documentation, and it will be what you make it. Although I have a soft spot for the PDP-8 and sympathy for those who do too, the SBC6120, especially a reduced cost version, doesn't pay the bills and I simply do not have the time to provide the documentation that it deserves. == Contents == * [[Overview]] * [[Assembling with or without the VT6]] * [[Assembling the PC Board]] * [[Assembling the Faceplate]] * [[Final Assembly and Checkout]] * [[Using the Front Panel]] * [[Hardware Description]] * [[Firmware Description]] * [[Detailed Parts List]] * [[Drawings, Schematics and Firmware]] * [[FAQ]]
