Lined VS Pi-Mainframe

Improvements to the Ada-GUI version of the MP music player and the Lined line editor

Got Lined to SPARK level Bronze, though I haven't figured out how to get it to check the main-program procedure, so this isn't very meaningful.

I had to remove the SPARK aspects from Lined to compile it with ObjectAda 10.2.

For maximal simplicity and minimal functionality, there's Lined.

I split the CPU simulations out of my Raspberry Pi Simulated Mainframe to provide more flexibility in their use. The CPU simulations are now in Sim CPU. In addition to the simple simulator that just blinks the lights in interesting ways, I have an 8080 simulator (and some simulated devices) more or less working. I am hoping to actually be able to boot CP/M on it before too long.

I've split "simulators" out of my Raspberry PI Mainframe Simulator. In addition, since I have an "Intel 8080/8085 Assembly Language Programming" book (from Radio Shack, remember them?) laying around, I've started writing an 8080 simulator. I've got over half the instructions implemented and tested. My goal is to be able to get CP/M running on it.

I picked up a MCP4725 I2C DAC and an ADS1015 I2C ADC from AdaFruit and plan to write drivers for them for my personal driver library (as a side note, if anyone wants to move any of these to the Ada Driver Library, feel free). I am thinking of using these to add another module to my Raspberry Pi Mainframe Simulator so that I can have some knobs and a meter doing important looking things.

I got inspired to make my own version of blinkenlights. This is before I heard about projects like the blinkenbone or PiDP-11. My version with 3D models to print and the Ada source code is here, Pi-Mainframe I think got simh running on it, booted RSTS/E and am now exploring PDP-11 assembly language for the first time since about 1985. Some of my routines are here, PDP-11 stuff. I hope that I've learned a few things since 1985 ;-)
