Hi!? There have been several requests for another round of the S-100 Bus Extender PCBs.? Since these are essential tools for any S-100 builder I think we should get some more.? We need 20 PCB pre-orders so I can make a manufacturing order. The S-100 Bus Extender board is ready for ?production?.? If you would like to get one or more of these very useful boards please do the new usual pre-order.? I will set aside your board so you get them as soon as they arrive. Here is a link to S100computers.com website with information on the updated S-100 Bus Extender board: http://www.s100computers.com/My%20System%20Pages/Extender%20Board/Extender%2 0Board.htm The PCBs will be $20 each as per the usual arrangement.? Shipping in the US is $3 for a single PCB and $2 for each additional PCB.? Shipping internationally is $10 for a single PCB and $3 for each additional PCB.? This is for the bare basics USPS first class postage with no tracking or insurance.? The builder assumes all risk of delivery as per usual arrangement. Please send a PayPal to LYNCHAJ at YAHOO.COM with the subject ?S-100 Bus Extender? and I will reserve your board(s).? Thanks and have a nice day! Andrew Lynch PS,? We are still doing another order for S-100 Buffered Prototyping board bus and have 6 boards in the queue.? If you would like one or more S-100 Buffered Prototyping boards please let me know.? The pre-order arrangements are identical to the others but please send them in a separate email so I can keep things straight on this end.
