    And the person that needed to get it,

    Got it ;)

    Good. Sorry that the price got driven up so badly, but glad to know it is in the right hands.

    The chicken says, "Cluck, yeah!"  I eagerly await a Fetzner/Guidry/Brent/Hagerty reproduction.

    Me too!

    I'm glad @FarmerPotato listed the price, because after that I didn't even bother to check it out.  

    I was excited until I saw the word "mockup".

     

     

    But I was using it as a segue to confirm something I suspect, but don't know.

     

    My assumption is that, if I see a device I know is of great interest and it isn't being talked about, it is an attempt to avoid guiding scalpers and "black hole" collectors to it.

     

    I'd hate for the community to miss out on a device I know is desired for documentation if I happen to be wrong. And I'm worried I've already been too precise in my wording if I'm right.

    No one's said it, but Extended BASIC is much more powerful than the console's woefully limited built-in BASIC. Even if you wanted to play with an unexpanded system, I'd get an Extended BASIC cart or put XB on your FinalGROM, and forget that regular BASIC exists.

    you know, I come from the Atari 8-bit world a I don't remember anyone modding the case of an Atari. Seems to be a thing more here.

    I think it is really a combination of two things.

     

    1. The TI's short life and quirky architecture led to it having an unusually large percentage of enthusiast users. The kind of people who view it as a tool to be modified to suit personal tastes, inside and out.

    Maybe they're just trying to fix the crappy video output, maybe they want the 32k as integral to the system's form as it is to the system's use, maybe they're through waiting for wait states. But moreso than most, it is a system that begs to be modified(and arguably HAS to be, thanks to the self-cleaning cartridge slot). And if the guts aren't sacred, why should the skin be?

     

    2. I mean, if the flimsy aluminum trim is gonna get damaged ANYWAYS...

    As for that list in the documentation, I did my best to track down which products in the 80's used the '9928.  It's tricky because there seems to be a lot of (slightly) incorrect information out there.  (E.g., I've seen Colecovision described on more than one website as having a '9918 which has never been true as far as I know.)

    Oooooh yeah. There's a tendency to write everything in the family down as 9918 or 9918a. From a specs and programming point of view, this is even accurate.

    ...

    And then you flip a coin to determine if the writer writes "9918a" for both the a and non-a families, or writes "9918" for both. Of which neither approach is right in any way.

    I believe it is true of the 99/4a in PAL land, but not the kingdom of NTSC.

    In America, TI used a 9918a that directly outputs composite video.

     

    The 99/4 with no a used a 9918, not a 9918a. Not sure on the PAL-land situation there.

    Why isn't/can't the 5v on the side port be used to power the CF7?  Is it not rated for enough amperage?

     

    I know it won't pass through the speech synthesizer. Is that the only reason for the secondary power design here?

     

    As I understand things, it is rated for very low amperage as the pin exists specifically to power the speech synthesizer. It was designed to supply pretty much exactly that amount of current, and not one drop more.

    After building and using a super cart it occurred to me that the RS232 might benefit from a battery backed-up RAM, letting the programmer load a driver that works for them.

     

    Has this ever been done?

    Yeah. That was the HDX mod, if I'm not mistaken.

    If money was not an issue, what fantasy item would you like to hook up to your TI?

    A flux capacitor.

     

    Seriously, it isn't what I want to hook to the TI, it is more what TI I want to hook things to. Lacking financial obstacles, I'd be figurin' out what to do with a 99/8 right now.

    One thing that would have been very useful, both now and BITD?

     

    If TI had produced a better data-recorder, that had a PWM drive control lead, in addition to the REM connector.  Then it would have been possible to have a datasette recorder that could fastforward, rewind, play at half speed, etc--- by sending the cassette mechanism more sophisticated signals.

     

    It could (and likely would) have been used for user-port like actions as well (since it would essentially be a 2 wire serial interface without flow control) 

     

     

    My assumption is they wanted users to use any old cassette recorder instead of requiring a custom device with additional expense. That was usually the goal with audio cassette storage.

    As it was not on either list, I've taken the liberty of scanning my Star Runner manual.

    ...

    I swear that paper doesn't look as orange in reality as it does on my screen(Understandably, it has yellowed with time and is no longer white). The blue mottling is legitimately a part of the manual, though. Part of me wonders if it wasn't an effort to stymie duplication efforts(it'd xerox TERRIBLY).
