SBC6120 (a build-it-yourself PDP-8 clone) Last Buy and End of Life

SBC6120 Last Buy and End of Life If you've never heard of it before, the SBC6120 is a PDP-8 clone, including an optional front panel, that you build yourself http://www.sparetimegizmos.com/Hardware/SBC6120-2.htm http://www.sparetimegizmos.com/Hardware/SBC6120_Front_Panel.htm Spare Time Gizmos has been selling kits for them since 2001. Last November I announced that I was running low on SBC6120 parts and that I wasn't planning to buy any more http://groups.yahoo.com/group/sparetimegizmos/message/110 and the last kit was shipped to a gentleman in France at the end of March. Since the web page was updated to show them as "Sold Out", I've been inundated with requests. Apparently people thought that Spare Time Gizmos would keep selling the SBC6120 forever :-) I really wish I could, but given the minimum orders for some of the parts and the rate at which it was selling, it would take years to sell off the inventory. I just can't afford to have that much money tied up waiting for somebody to buy it. But, we can do one "last buy" for the SBC6120s, if we can get enough people together to make the minimum orders for 6120 chips, bus connectors, and PC boards. If all the people who have emailed me recently sign up, then that should be more than enough! The last buy will be for a SBC6120 partial kit that will include: * A four layer, silk screened, solder masked PC board * The HD6120 chip and 3 HM6208 SRAM chips * The special stacking bus connector I don't know exactly how much this kit will cost - it will depend on the price I can get for the parts - but I estimate that its going to be around $150. All the rest of the parts used in the SBC6120 are modern, easily found parts and there's a complete list, with suppliers, in the back of the manual http://www.sparetimegizmos.com/Downloads/SBC6120.pdf Pre-programmed EPROMs and GALs, if you need them, are also available from the Spare Time Gizmos web page. I may also sell full kits of all parts (I used to before I ran out) if there is enough demand. BTW, the SBC6120 is an entirely "open" design. All the schematics, firmware, and GAL programming is GPLed and available from the web page. If you're interested, email me and I'll sign you up on a list, and if we get enough orders then I'll let everybody on the list know the details. Oh, one last thing for people in the EU, the SBC6120 parts are not RoHS compliant and it's not likely they ever will be. If you want one, you'd better get it before July 1st!
