    After the dalliance with a CP Code reader coming off the reverse of a
    Bermuda riser, I was bringing the generators up to speed before phasing
    them to the grid. Add coffee. Watched the walls flex.

    Wow. We suck. No link from the 90 planar page to any DBA ESDI pinouts.
    Must be them constantly drunk Moravians. Lazy bastards. Long, rambling,
    near incoherent longing for the glories of the Red Banner Tractor
    Factory #57. slivovice flows freely.

    But anyways, what pins are needed, and what's the circuit to produce the electronification needed to drive the Holy HDLG-2416LED ?

    Good point. Fixed.

    Toš šak tobě by se ňáká ta slivovica taky zešla, abys přečkal tu drsnů

    8 data lines, 16 (?) address lines, and some basic control signals - all available on the DBA connector. Then you need something to realize the
    address decoding (PAL?) and one 245 (normally on the planar). Pretty simple.
