Thread: 4004 Development System

  1. #1

    Default 4004 Development System

    Hi all,

    Is there any interest in a modern 4004 "trainer"? I am trying to gauge some interest in the community to see if it would be worthwhile developing such a system. It would have similar functionality to an Intel Intellec 4.

    Thanks,

    Kyle

    Did you ever heard of a/the IASIS 4004 trainer? It might be nice to make yours compatible with this as well.

    Hey Bill, I've not heard of one before. Do you have one, or the associated documents? Didn't see anything on eBay or bitsavers pertaining to it.

    I have a manual only. ...paging through it....it's based on the MCS-4. A home study book that walks you through the instruction set, etc.

    here is one

    Do you have ROM listings in the manual? How about schematics? Maybe if you get a chance, you could scan some pertinent pages.

    I couldn't find any more information on the 4004 trainer pictured, other than describing what it can do. No schematics, code, anything.

    I have some ideas of what I want to do, but it'll take some time. I'll get there eventually! I have an Intellec 4/40 to play with, which gives me the ability to do some software development without any extra hardware.

    I believe he used a 4289 chip. Do you intend to make a
    interface circuit to go between the pmos to ttl or use
    something like the 4289.

    I was going to use either a 4008/4009 combo or a 4289. I may design a board that allows one to use either one or the other, along with either a 4004 or a 4040.

    Although, I see these available on ebay sometimes,
    it would be better to make a simpler interface with easier
    to get transistors and a few IC's.
    It is cool to use the original parts Intel created but
    this could cost unneed pressure on hard to get parts.
    Also, nether of these parts support the full 4002 RAM
    instructions.
