Original Basic Binary Loaders
These are disassembled and newly-commented versions of the old BBLs. The machine code used for the disassembly was obtained from the "STANDARD SOFTWARE SYSTEMS Operating Manual" for the 2116A/2115A models (1967).
A simple program to demonstrate the various shift and rotate instructions.
The front panel is used for the display.
This program was obtained from the back of the 2116A Vol. 1 manual.
ABL - ASCII Binary Loader
A new basic binary loader (BBL) for downloading a binary image into core, but requiring only ASCII characters to be transferred over the communications link.
It is coded to use a type 12531B/C/D I/O interface (serial async RS-232), located at octal channel 11.
As with the original binary loaders it resides at the top of core.
