I will add to my order boards for others who are interested. I am not planning to kit or assemble. You will have to do that yourself. For information on the board see http://www.pdp8online.com/mfm/ Email me if you have any comments or questions. I did two different layouts, one all through hole and one with 3 surface mount chips that has some minor advantages. See link above for discussion. I plan to only order one version. If you are interested in a PCB's email me with 1) How many you wish 2) If you prefer or are only interested in the through hole or surface mount version. Unless you state I don't need to I will email you back when I get ready to order with the final price for confirmation that you still wish them. I plan to collect money when I am ready to ship them. The cost to make one is: Beaglebone $55 (they increased the flash by 2G and the price by $10) PCB $30 (depends significantly on quantity) Parts $54. Can reduce by $24 if you don't need the holdup capacitors. See the BOM for parts and prices. See description of board for what the holdup capacitors do. TBD Shipping Unless only a few are desired I will likely buy a couple cheap PCB's without the hard gold on the edge fingers to verify I haven't made a serious error. This will delay final order. I tried to get my cat to peer review but it only shredded the paper.
