Hello Sean. Ok. I'm back. Sorry for the silly question of which DL11 board you have. You mentioned it in the board list. Anyway, here's how I have connected the M7856 to a VT220 (EIA, RS-232C). +------------------+ |.(B) ...... (VV).| |/ |.(A) ..... (UU).| | =====================================================|\ == (viewing the edge of the M7856 where the BERG connected is) The lower righthand side pin (closest to the board is A. Right above it is pin B. At the lower lefthand side, the pin closest to the board is UU, and above it is VV. Then, the alphabet on the BERG connector is as follows. B D F J L N R T V X Z BB DD FF JJ LL NN RR TT VV A C E H K M P S U W Y AA CC EE HH KK MM PP SS UU The following wires run from the BERG connector to the DB25 connector I have at home (forgot to write down if it is male or female). Also, because I made it fit to a longer wire with DB25's at both ends it *_might_* be a null-modem cable.... BERG DB25 =================== VV | 7 DD | 20 V | 4 J | 2 F | 3 Further, a small wire connects (E) to (M) on the BERG connector. BTW. My 11/35 has an BM872. It is a boot card (dual) with diodes on it to form a matrix addresslines/datalines. So, you can solder your bootstrap program's zeroes and ones in real hardware :) Success, Henk.
