    Well, I wrote the first versions 8085 emulator using only the Prop Demo board LEDS as debug output!

    Then I graduated to an old 2 * 20 line LCD which got things running up to the CP/M command prompt.

    Since then it's mostly the terminal in BST unless I can borrow the telly for a bit. Which is not so good for CP/M anyway.

    Outputs:
    PST: always
    TV: Tried it but old small tv's w/video not readily available. Daughter took my 1987 Amdec 300 computer monitor for her vcr.
    VGA: Just tried it yesterday. Fun to play with RGB. Up to my *** in old VGA screens!
    other: LCD: 2x16 and 2x8.
    3.5 digit LED: made a digital Volt-Amp-Freq meter once. (w/dimmer!)
    Proprietary HTML, SNMP, Telnet board. I just send it serial, the board does all the magic.

    Inputs: mouse: not yet, but today ain't over.

    Q1: TV for the win--I have used VGA exactly 6 times. smile.gif
    LCD--Still haven't found out how, but am working on it...

    Q2: I love using a mouse, but it is difficult to interface to the Gadget Gangster pcbs... So I use it primarily with my demoboard. Verdict-- I use it occasionally.


    The one thing I must say about VGA vs Composite is that it is a LOT harder to connect to VGA and requires a mot more I/O, while with a TV, all you have to do is rummage around in your closet for a cable and you're set to run PropDOS. smile.gif

    Here's the question... If your in front of the computer, lets say programing the chip. Then don't you need to use a monitor? So it could be assumed that everyone who can actually use the chip could purchase a vga spliter or they might just have a second monitor to use to display the vga output...

    ...or just do video capture and put your propeller in a window on the PC display.

    It's really easy to come by an extra VGA screen these days. Space is a premium for me though, as is portability.

    But yes, I think people could just get a switch, or extra screen or maybe just have one.
