For CGA emulation in Hercules there is HGCIBM. Is there a solution to emulate EGA in Tandy (PCJr)? Because the video modes are similar (320 × 200 × 16) — https://groups.google.com/g/comp.sys.tandy/c/qQ7XYKSLItA And also, perhaps, similar solutions for Olivetti and Plantronics Colorplus?

The author did a great job adding Tadny support to Q(uick)Basic. However, as I understand it, new commands have been added to draw graphics, and LINE (PSET, CIRCLE) is no longer working. Accordingly, graphics are not displayed in ordinary BASIC commands.

Perhaps the op should consider using C or C++. Or even Turbo Pascal. Helped at the cyberforum: ON ERROR GOTO etrap er = 0 SCREEN 12: SCREEN 0 ON ERROR GOTO 0 IF er = 0 THEN a$ = "VGA": GOTO pr ON ERROR GOTO etrap er = 0 SCREEN 9: SCREEN 0 ON ERROR GOTO 0 IF er = 0 THEN a$ = "EGA": GOTO pr ON ERROR …

Is it possible to determine the graphics adapter using Q(uick)Basic, at least for compatibility with CGA-EGA-VGA?

Thanks again. Can't run SCREEN 13 mode on QBasic despite running TCR — Re: TANDY Dos-Gaming-Thread (1000RL/HD) Now going to deal with the attached library.

Greetings! For example, Hercules Graphics Card (720 × 348 × 2), is emulated by the resident program msherc.com ( qbherc.com ), and the CGA modes are emulated in it hgcibm.com or simcga.com , and some ohters ( 320 × 200 × 2 or 620 × 200 × 2). Hercules InColor Card is emulated as well? Interested in …

Thanks a lot for advice! As far as know, Tandy and EGA modes are not compatible. Is it possible to emulate the SCREEN 7 mode 320 × 200 × 16 in Tandy (PCJr)?

Is there a Tandy resident driver (TSR) that allows to use the missing SCREEN 5 and SCREEN 6 video modes in Q(uick)Basic?

Excellent reult! Is there a Tandy resident driver that allows to use the missing SCREEN 5 and SCREEN 6 video modes in Q(uick)Basic? P. S. For the Hercules, a similar one existed in the form of qbherc.com (msherc.com).
