doku188Last nht I completed my 80188 based SBC-188 build. It is a ECB board desned by John Coffman in the Retrocomputers forum that provides an Intel 80188 coupled with 1Mb of RAM and 128k of ROM.The BOM for the 3.1 and 3.2 boards are the same except for the addition of the 3×2 pin_array. The GAL .JED files are the same. Use sbc-188v3-gal-3.0-002.zip (above)..
