Schematics of Atanasoff-Berry Computer logic circuits?

Hi, to make use of my spice tool set was indeed the first idea, but I dont have enough time yet so I didnt answer. Its no problem, there are still models for tubes available and its not to hard to make new models for the originally used tubes. The schematic is quite simple, maybe you can remember the first logic chips available where made in so called RTL (restistor Transistor logic), which is exactly the same as the ASM do, only the levels are shifted. Because of the problems with the resistor networks, the so called TTL chips are developed, which replaces some resistors by transistors. I am shure there is enough information out. Once you have seen how RTL works, you will easily find out how ASM works. Sorry, that I am short?with time, but I am very interested on this project and as I can spare some hours, i will join, if possible. With best regards Gerhard
