Bob Armstrong at www.sparetimegizmos.com is trying to get enough order requests together to meet the numbers necessary to justify a last time parts order of his sbc6120 kit of a pdp-8e work alike clone. This kit is based on the harris hd6120 used in decmates and runs the pdp8 instruction set natively. He left a message on the alt.sys.pdp8 newsgroup. You can contact him at bob at jfcl.com. He estimates costs at $150 U.S. for a circuit card, cpu chip, static ram and stacking connector. the rest of the parts required are still manufactrured and available thru places like digikey/mouser/newark. About 50 people built this sbc from the original parts buy, it works. For $ 150 bucks how can you go wrong? I'm not in any way related to bob or sparetimegizmos. But I can't buy one unless others make the bulk parts order cost effective for Bob. He had 18 orders and needed more than twice that much by 10 june to go forward.
