3-2COLPL.65D | OS65D V3.2 with Generic Computer Products Color Plus Hi-res Routines V1.1
Includes Color Plus BEXEC* and drivers for OS65D3.3 and OS65D3.2 along with sample programs. Supports a superset of Apple ][ graphics instructions. Looks like Color Plus board can interface as Head End Card on OSI or run as standard 48-pin bus card. Supports 15 colors + transparent, Resolutions up to 256x192, 32 sprites, 40x24 Text, 8bit analog joystick(2) or paddle(4) support. Sounds like TMS9918 based. Anyone have details?

C8-Active.65d | Dan Schwartz's OS65D 8" disk
Contains: ** DQ SECRETARY *** by Dwo Quong Fok Lok Sow - A copy of the full, original "Dog Star Adventure" (early TRS-80 adventure game) adapted for OSI, NOT the abbreviated version that was sold for OSI at one time. - A cleaned-up version of the Haunted House adventure game. - A fixed version of my "Hex 15 Puzzle" that always generates solvable puzzles. It also won't cut off the left edge of the screen if transferred to and run on an unmodified C1P. - Boots to DQ Secretary menu. Working backspace via backspace key on PC keyboard/rubout key on emulated OSI keyboard in both Basic and 65D (3.1/3.2). - Basic supports changing workspace limits with NEW (e.g. NEW 12*256 = reserve one file buffer), computed GOTO (e.g. GOTO 100+20*N), and doesn't require THEN keyword in most IF statements. - Old OSI utilities CREATE and ZERO do properly zero out the space claimed. |
