  1. So far, when I answer by saying "This call is being recorded for fraud prevention purposes, is that okay?" I get either (A) They immediately hang up. (B) "No sir, it's not being recorded." to which I reply "No no, I'm recording it to prevent fraud" after which they hang up. (C) [BY FAR the most common] the computer-controlled message-spewing system has no idea how to respond to that, and so it cavalierly proceeds to tell me I promised them a $35 donation six weeks ago. I usually respond by saying "It's taped to the back of a tortoise, he'll eventually wander your way."
  2. In these pics, are you attempting to assassinate the tornado?
  3. If he doesn't go for the "there's something on the wing!" gag during the flight I'll be disappointed.
  4. Oh, I think I get it now. It's not about refusing to learn kicad - this designer friend of yours wants his boards done the old(er)-fashioned way as an aesthetic choice. And, that is a very visually appealing board design he has there. I've actually seen some of those acetone board-fab videos before on YouTube, so I know what you're talking about. The process looks quite difficult, but as you say, it's technically do-able (just not at large scales) if you can find someone willing. I hope the designer is able to find someone - maybe try contacting the people who made those YT videos; since they already have an interest in it and have already put time into getting the process down, then maybe they'll take an order, for the right price. Just a thought.
  5. Although my current favorite keyboard is a Logitech K120, that company also makes the worst keyboard I have ever used: the K380. This is the wireless (Bluetooth) keyboard that can switch which device it's connected to; I bought it because it solved a problem I had at the time (lots of computers with small desk space). The connectivity and switching aspect worked great, but the keyboard itself was awful to type on. It would often log two key presses even though I felt like I only pressed it once - on any key. This lead to a lot of doubled letters or unexpected confirmations (if it logged the 'return' key twice when I only intended once). I thought it was faulty so I returned it, got another one of the same model, and had the same problem. I'm assuming the problem lies in the way the keys are made (they're very flat and have a shallow travel distance), but I guess it could be a glitch in the bluetooth connectivity, for all I know.
  6. Neat. What do the three keys on the LH attached module do? Are they custom assignable? Also... no cursor keys? My favorite keyboard was a Dell Quietkey from (I think) the early '90s. I used it well into the modern era, with a PS/2 > USB adapter. Alas, I spilled a drink on it about two years ago and fried part of the traces inside. These days my favorite is a relatively inexpensive Logitech K120 with 'half height' keys.
  7. Ohhhhhh, I finally got it. It took me way too long, but it was @kelli217's trochaic tetrameter clue that finally turned the lightbulb on. Since Mighty Morphin' Power Rangers never had a movie (as far as I know), it must be... Just kidding of course. As you likely know, I got that from xkcd, which also helped with the trochee clue. The only thing that's throwing me off is... I never played any TMNT video game, but I don't recall any magic in the MNT universe, or transformations. So maybe I haven't guessed correctly!
  8. Thank you all who answered. @paulscottrobson's answer happened to be the one that made it the most clear, and after reading that one, I went back to read the other two and they also made more sense. Two last clarifying questions, if no one minds (I hope these questions are helpful to the thread in general)... Why would we need 9 address lines to access a 256 byte window? In my ignorance, that sounds like it's addressable in 8 bits. So when the CPU is writing to the area that is acting as the 'window', it's writing to VRAM instead of CPU RAM? Or the write affects both RAMs?
  9. So, I ordered the C256 Foenix Gen X, which will come with a 65C816 processor. It will also come with a slot into which you can insert cards that Stefany sells that allow to use one of your choice of a handful of other processors alongside the built-in 65816. I have no interest in other processors and have not preordered one. I'm a musician and I have been looking for a way to get into chiptune creation more deeply. I am also an 8-bit era programming hobbyist (not expert, but not a newb either). A few years ago I adopted an abandoned C64, nursed it back to health, was pleased to find that its original SID was still working and have been learning to program for the SID directly onboard in assembly. It's fun, but I haven't yet found a workflow that really makes it practical. I started work on programming my own little compositional utility, when news of the Gen X reached me. The Gen X will include five different flavors of sound chip: SN76489 Two Gideon SoftSIDs in FPGA, and two more slots for hardware SID chips (real or emulated) OPM (YM2151, as a JT2151SA - an FPGA version Stefany designed that also incorporates the amp chip that's supposed to always go with the 2151.) OPN2 (YM2612, as a JT2612SA - similarly, an FPGA version) OPL3 (YMF262, apparently as the actual F262 chip) ...also a piezo "PC speaker" for what it's worth, heheh. And, it has a MIDI input (No Output or Thru). I like MIDI a lot, I've been working with it (even at a binary, programming level) for a long time and know its ins and outs well. So what I'd like to do is program (in 65816 assembly) a program that will let me route the incoming 16 MIDI channels to whichever voices of whichever chips I want, and assign MIDI parameters to whichever aspects of those chips I want. I see this as a do-able challenge. The hardest part will actually be learning to make the graphical interface on the C256, since I'm really ignorant about graphics processing, and the Foenix is not the simplest setup to learn learn on. I'll likely do it in character graphics. There is also a tracker (already written) for the existing Foenix systems which should port easily to the Gen X, so while my own MIDI handler is under construction, or if I can't write it after all, I can fall back on the existing Tracker (I don't care for trackers, frankly, but I can use one if that's what's there.) The five chips and MIDI input are also available on the FMX, but as far as I can tell this is not being sold. The chip shortage would have forced Stefany to redesign it to bring it back to market, and my understanding is that she decided to move on to her next thing, the Gen X, instead. So, I've been mostly ignoring the 68k news because that's not my chip of choice. (Stefany has said, however, that it is her favorite CPU.) I should say, I may have misrepresented the A2560: I don't think it's 68SEC000 is built-in after all, I think maybe it has no built-in CPU but the 68SEC000 is the card that it comes with (swappable for other CPU cards). The Foenix systems have not yet involved a 68k CPU, the forthcoming models will be the first to have any flavor of the 68k series. For this reason, the already-developed software all 65816 based. One big project that everyone's trying to make a push for right now is a C-based Kernel that can be compiled for any of the potential CPUs; there's a team working on that one. There are other works in progress. A member named 'vinz67' is working on porting EmuTOS for any of the supported 68k series. Another user named 'gadget' is working on her own OS, aiming to be usable by any of the CPUs. So I guess the short answer to "is there a fair amount of.." is "No, not yet." Or at least, not specifically by the Foenix crew; how compatible existing 68k homebrew material would be, is beyond my knowledge.
  10. I'm wondering if someone could, very briefly, explain/summarize the difference between these two graphics approaches. (Not necessarily @paulscottrobson, your post was just a handy one to quote that mentioned both.) I'm not a graphics guy at all (all my work in assembly has been SIO/text, or sound), and for either the X8 or the X16 I would have to learn how the graphics system works. For anyone else on the forum here who might fall into that same boat, the briefest of comparisons might aid the discussion. Not a tutorial on how to use the two, just maybe a 1-2 paragraph overview, would be greatly appreciated. (Apparently the 'window' approach requires more pins on the FPGA - why? Does one or the other demand more of the CPU's cycles? etc.) If such an explanation already exists (possibly in another thread) then I apologize and would appreciate a link. Thank you!
  11. The website could be a little more clear about the different models and their releases, but, if I understand correctly: What's shipping in September are two models in the new "A2560" line, an MC68SEC000-based version of her existing Foenix U and U+ consoles, as well as the original (65C816-based) versions of the U and U+ which were unavailable for a while. These will begin shipping in about three weeks (so, late September). The Gen X is still slated for October or November. Apparently there's also an MC68SEC000-based version of the Gen X in the pipeline, called the A2560X, launching around the same time as the Gen X. (Both have the slot for a second processor; the difference is the built-in processor is the 65816 on one and 68SEC000 on the other. Maybe also something different about graphics, I don't know, I'm not a graphics guy.) And, somehow, a keyboard-case variant. We're over here arguing about whether the X8 should be allowed to ship or not and she's over there bringing to market whatever 3 or 4 new versions popped into her head this year. We'll see how these two different approaches play out. Personally I'm pleased to be in both communities. (Also, as a music guy, I'm so excited by the idea of having five sound chips in a system that I can program to work however I want, that I am optimistic about the Gen X. I did indeed put my money in for a pre-order, a few months ago.)
  12. If you get a chance, show us a picture! Even if it's still empty for now. Would be cool to see.
  13. That game looks like fun! And the creator seems very nice. Thank you for sharing it!
  14. Yeah I'd never even heard of the first game, and while I had heard of the last one I'd never seen the box art (and didn't expect it to look like that!).
  15. I haven't yet, but I am looking forward to it. I was sort of waiting for the audio chipset to be finalized, and sort of waiting for real hardware, but mostly just busy with other life stuff. I hear there's already a tracker for it - or for the emulator, anyway. I'm hoping I have time between now and launch to finally get the emulator going and familiarize myself with it.
