Paul Kimpel	6c51a5803b	Commit 220 emulator version 0.4: 1. Minor improvements to magnetic tape implementation and rearrangement of code. 2. Correct Processor CAD/CAA/CSU/CSA operation for operand signs other than 0 or 1. 3. Correct Processor LDB to load only the low-order four digits of the operand into B. 4. Correct Processor SLS shift count; improve mechanization of other shift-left operations. 5. Fix beforeunload event registration for Cardatron and Console devices. 6. Implement "Whippet" mode for Console TTY devices to print at 200 CPS instead of 10 CPS. 7. Expand B220PaperTapePunch translate table to cover all 256 8-bit codes; scroll end of punched data into view. 8. Minor code cleanup in B220PaperTapeReader.	2017-11-19 17:56:09 -08:00
Paul Kimpel	d518d6e044	Commit 220 emulator version 0.3a: 1. Commit initial (incomplete) implementation of magnetic tape drives (TSU) and control: MLS, MRW, MDA, MIW, MIR, MPF, MPB, MPE, MIB, MIE. 2. Change B220SetCallback.js "setImmediate" mechanism to use DOM Promises instead of window.postMessage(). 3. Minor styling and window positioning changes.	2017-10-19 09:18:48 -07:00
Paul Kimpel	a95b75bc88	Commit retro-220 version 0.03: 1. Implementation Paper Tape Reader devices and op codes. 2. Commit standard and inverse-format paper tape loaders for WINTER.PI program. 3. Fix positioning of Cardatron and TTY/Paper Tape Punch device windows.	2017-05-29 14:03:42 -07:00
