I'm trying to restore a Victor series 1400 CRT tube display calculator, and wondered if anyone had any information about them. It's got a 3" or so green CRT display with masks for the numbers, and a big board full of mostly unmarked chips. It used to work fine, but one day it quit, and I have no clue why. It's just totally dead. Have checked the fuse, caps, etc. A schematic would be wonderful. -Bill Richman (bill_r(a)inetnebr.com) http://incolor.inetnebr.com/bill_r - Home of the COSMAC Elf Microcomputer Simulator, Fun with Molten Metal, Orphaned Robots, and Technological Oddities.
