Info on SB-104 display drivers

[Michael Tallent]

My National data book for 1973 lists the DM8880, it says it is custom
design to drive the Sperry Panaplex II display.  The DM8880 has a
minimum breakdown voltage of 80 v.  I don't know what voltage the SB104
operates at so if it is very high then a substitute will be difficult.
