this ISA wire wrap board is essential and a lot cheaper than the PCI bus version. $24.95 vs $75 although the one i use has a ground & +5V going around the perimeter this one will do fine. It is Jameco Part # 28206ca.

The programming information is included in the programmign datasheet, you need to follow the (very unclear) instructions in that. But you do have to supply the full number of clock pulses, in order to clock the data in to the correct place.
tell me about it ( very unclear) is an understatement..
have you seen their Memory Maps ? Absolutly laughable.. or cryable..
So i do need the clocks on the commands without the associated "data" ?
i apologize for the format of the command list (below) but it was hard to post the chart from the pdf.
Load Configuration [ X X 0 0 0 0] ( 0, data (14), 0)
Load Data for Program Memory [ X X 0 0 1 0] ( 0, data (14), 0)
Read Data from Program Memory [X X 0 1 0 0 ] ( 0, data (14), 0)
Increment Address [ X X 0 1 1 0]
Begin Erase Programming Cycle [ 0 0 1 0 0 0]
Begin Programming Only Cycle [0 1 1 0 0 0]
Load Data for Data Memory [X X 0 0 1 1 ] ( 0, data (14), 0)
Read Data from Data Memory [X X 0 1 0 1 ] ( 0, data (14), 0)
Bulk Erase Program Memory [X X 1 0 0 1]
Bulk Erase Data Memory [X X 1 0 1 1]
if you look at this pitiful "chart" the
increment address,
begin erase programming cycle,
begin programming only cycle,
bulk erase program memory &
bulk erase data memory , have no associated (start bit,.. 14 data bits,..stop bit)
