I'm selling off one of the SBC6120 prototypes from VCF 6.0 on eBay http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem <http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2782363270> &item=2782363270 (I decided that four prototypes was more than anybody could need :-) This is the one on the far right (sitting on the easel) in the picture http://www.vintage-computer.com/images/vcf6/sbc6120.jpg This unit includes the lights and switches front panel, black aluminum bezel for wall hanging, a 16Mb Compact Flash card for mass storage (that's the equivalent of eight RK05Js!) and a wall wart style power supply. It's all ready to plug in; all you need to add is a terminal. If you haven't heard of it, the SBC6120 is a fully functional PDP-8 clone built with contemporary (more or less!) electronics. The SBC6120 executes the PDP-8/E instruction set, includes a full 32K words of main memory and KM8E compatible memory management, has a KL8E compatible interface for an RS232 console terminal, can connect to any IDE/ATA disk drive, and best of all (as you can see from the pictures!) has a fully functional lights and switches front panel. The SBC6120 can run all standard DEC paper tape software, such as FOCAL-69, with no changes. OS/278, OS/78 and, yes - OS/8 V3D or V3S - can all be booted on the SBC6120 using an IDE disk drive as mass storage devices. Bob Armstrong
