Loaded two IBM 1130 oriented projects into Github

SHARED THE IBM 1130 CONSOLE PRINTER EMULATOR ON GITHUB

https://github.com/cclaunch/PC1053 is the project entry for the console emulator, with Fritzing diagrams, Arduino code, plus an optional testdriver to put the emulator through its paces. It is now sitting next to my 1130 waiting for when I can power up and do the final checkout on a live machine.

PREPARING THE SUBSTITUTE CONSOLE DISPLAY LIGHTS FOR INSTALLATION

I did a final checkout of my three PCBs that will install in the console display pedestal on the IBM 1130, above the console printer. The existing IBM method of inserting the nearly 200 incandescent bulbs plus the SCR driver circuitry is a nightmare to service, so I had designed and built this alternative that uses miniature incandescent bulbs plugged into large PCBs which sit directly on the rear face of the display honeycomb.

UPLOADED THE IBM 1130 LOADER MODIFICATION TO GITHUB

I whipped up a simple Arduino based enhancement to an 1130 that simplifies and speeds the entry of data into core. The user switches the 1130 to Load mode, then connects to the Arduino and issues words of four hex digits to have them loaded into core. https://github.com/cclaunch/1130Loader

If the word being entered includes an @, that character is ignored and the hex word is loaded into the IAR so that subsequent words will load in core starting at that address. Similarly, if the word being entered incudes a #, that is ignored but it toggles the control over the 1130 and loads that word as the IAR. Initially the device is not controlling the computer.
