This is very impressive. A nice 1970's build of industrial equipment, looks like a 1974 build from the chip dates. There will be good work to do, in reading off the ROMs and working out how it did what it did. restoration to operation is a doable challenge, depending. And apparently there may be loose ROMS, they might provide clues about how the compiler worked. "Compiler" being the action of programming those ROMS for use in the companion controller (another 4004 unit). "read the fine documentation" that Christian pointed to for details. Christian, thanks for letting people know you have this, and for preserving it. In time, if Web-references get around, people who knew this may contact you, give you more information, have other units. That's why I have a Web site, among other reasons. Hope you find a venue for further technical discussion of this and work done with it. Regards Herb Johnson On 1/16/2024 1:10 PM, Christian Liendo wrote:
Here is a picture of the unit. I pulled it out of storage and I didn't have a day to really work on it. But it should give you an idea of what it is and how it was assembled. -- Herbert R.
