Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Forum Index : Microcontroller and PC projects : IBM 1401 restored

For anyone interested, I recommend to take a look at Marcs Videos about restorting a Apollo Guideance Computer; a quite complex task.

One of those Guys involved even wrote a Guidance Computer Emulation on a FPGA with the ability to attach real AGC Hardware to it, in order to test their functionality, reading / checking Memory modules and so on.

Btw, this is a Video which shows how the AGC was built back then.

High school in 1976... I had a dial up(110 baud phone cradle modem) account with the University of Minnesota mainframe. Whopping 256kb of storage(other students had 64kb...) I was writing a basic word processor program and the UofMN head of computing called me and told me he liked what he was seeing and upgraded my account.

My senior year when I was putting finishing touches on it he partnered me with a grad student to really turn it into useful software. The college ran it for 3-4 years in their data centers then the Apple II's and IBM PC's took over. Earned me credit for the first 2 years of programming classes! Cost me zero so a huge tuition save!

I had already graduated college by then but someone ported my program over to IBM PC use and put it up as freeware. Not sure how many actually used it, by then Easy Writer then Word Star were in use on the PC's.

To think I lived from the start of this mainframe to what we have now... my cell phone is more capable than my first PC was LOL
