I still have six (6) of the S-100 bus extender boards left if you are looking for them. http://s100computers.com/My%20System%20Pages/Extender%20Board/Extender%20Boa rd.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 send your board(s). Thanks and have a nice day! Andrew Lynch PS, I am also accepting pre-orders for the S-100 buffered prototyping boards and will be making a manufacturing order soon. All the details are the same as the S-100 bus extender except send a message with "S-100 buffered prototyping board" as the subject.
