    1) The man himself wrote a description on post 11 here:

    2) Yes. New hardware is constantly being developed by those just insane enough to attempt them. DPC+ was an enhancement over Crane's DPC co-processor design...and the recent CDF is an original (and more sophisticated) co-processor approach.

     

    Spiceware wrote how some sample code is reduced in size by utilizing different co-processor methods here (post #5)

    3) Yes. Anything that is using co-processor hardware as part of its design.

     

    4) Possibly irrelevant. Custom hardware means one can create new rules that may or may not utilize TIA (like AtariVOX).

    Just read the post, very interesting! Just thinking that the 2600 can have more features via expansions just keeps making it more and more awesome! So the TIA can be used as a 4 bit DAC? This actually gives me an idea for some demoscene, though I've no way nor knowledge to develop and implement it; and even if I did, my 2600 doesn't work right now...

    As for question #4, I was trying to ask if sound based expansions could be added to TIA tracker for advanced music, in a way similar to the expansions you can use in FamiTracker, though I do understand the possible issues of nonstandard expansions.

    Up until now I've never really thought about how Pitfall II had both the soundtrack and the sound effects at the same time. A quick lookup on wikipedia says that the game uses a special chip to give better graphics as well as sound, in a sense it's like the expansion chips for the NES to give it more sound options, or the Super FX chip for the SNES. While I doubt any other official games used an expansion chip for the 2600, it does raise some interesting questions, of which I will list four:

     

    1) how does the chip work and what did it do?

     

    2) would other similar expansions be possible?

     

    3) are there any homebrew games that use an expansion chip of sorts?

     

    and lastly, but kinda optionally,

     

    4) Can this kind of functionality be added to TIA tracker?

    I found out rather recently that beepi, the atari st/falcon emulator for the raspberry pi, has a pc version. I figured I'd give it a try, but I got this error at boot-up on virtualbox:

     

    This kernel requires an x86-64 CPU, but only detected an i686 CPU. Unable to boot - please use a kernel appropriate for your CPU.

     

    Here's the thing though, I already knew the solution to this problem; just go to BIOS and activate hardware virtualization. The problem here is that that option was ALREADY ENABLED, even before going to the BIOS menu! Any help appreciated!

    While I and many others have a hankering for an atari st to mess around with, I have noticed that finding original hardware that is still in working condition to not only be pricey, but also a rarity (although I have found several 8-bit systems on ebay, as of 12/2017); especially if you want a set complete with monitor, keyboard, and mouse along with the system itself. It seems, however, that there are a select few other computers from years past that have had a 'remake' of sorts, (case-in-point, https://www.specnext.com/) which has left me wondering: are there any modernized atari st systems that not only exist, but are still available for purchase?

     

     

    (second question: can the same be said for the atari 8-bit systems too?)

    I'd be interested in a homebrew compumate. I have a little experience in hardware design, but I have always been an amateur.

    good to know I'm not the only one! It could be done, perhaps with enhancements like better keyboard, sd card support, etc.

    After getting some things from the basement for my computer, I gazed forlornly at my well-used 2600. I remember reading about a perhifrial called the compumate, which converted the 2600 from a video game console into a weak but useful computer. That got my wheels turning, and left me wondering, has anybody ever thought about making a homebrew compumate? And that is the question/discussion I cannot get out of my head.
