  1. Just goes to show you my memory isn't all that great Wow that would be nice 👍 Although I won't hold you too it, since it probably sits at the bottom of the stack of things you'd like to do
  2. If I recall correctly @flashjazzcat never continued with XEP80 support because of not having the actual hardware for one. So whatever version of TLW there was with XEP80 support, I'm pretty sure it predates the latest version by quite a bit as in years. I don't even know if it actually saw a public release. Hopefully Jon can hop in here and give us an update.
  3. For me it was interesting for maybe an hour or two when I was connecting to various active BBS's, but quickly the novelty wore off, and then all the reasons why I stopped using my A8 to go online focused into realty once more. Personally I think instead of going back into the past with this next generation tech, instead we should be focused on something more modern now that this tech allows for bridging the gap. As to what that would be... well I for one would find being able to log into one (or all) of my existing email accounts in either POP or maybe even IMAP, and then send and receive text messages, a very useful app on my A8. This is something that is bridging old with new in a practical and useful way.
  4. That would be particularly appropriate for all SMD based boards 👍
  5. The gumby circuit has been done many times, with small variations by various people including myself in the 1088 series boards, so no real point in me publishing anything specific to the 576NUC+. Besides I really don't wish to encourage dual Pokey setups with how difficult they already are to get a hold of. I was under the impression that PokeyMAX was a very good FPGA clone of the original Pokey sound. You feel differently?
  6. @ivop I think this will cover the dimensional data you were after. SIO2MIDI-S2.dxf
  7. Not a bad idea, although I'll leave that up to others to do whatever they want. For me this project arrived where I intended, and I consider it completed However with that said, the schematics are available for anyone that wishes to go in some new direction.
  8. I wouldn't count on DVI working. I tried it on a fairly new DVI only monitor and it was no dice. Best to stick to monitors with HDMI input. Because there's no guarantee the DVI will work even with an HDMI to DVI adapter. Edit: Just add to that, the 1080P mode seems to work the best at displaying a nice centered image with all the content viewable, which really isn't compatible with those older DVI computer monitors. BTW the 4:3 aspect ratio setting on the HDMI converter works great, and makes up for the HDTV possibly not having that ability.
  9. All thru-hole parts on the main board, and the AV-to-HDMI daughter board is purchased as an assembled item. Check out the BOM on that XEP80-II page I linked to (scroll down to the bottom of the page to see the downloads). It's a pretty easy build - takes me about 3-4 hours max without breaking a sweat Because of the general electronics shortage you may have to do some substitutions, but all the parts are pretty generic in nature so a different manufacturer is no biggie.

  11. I did do prototype a board called the XL-CF4 which I put into my 'Monster 600XL', a title that i gave it due to all the upgrades inside. It picked up all but one signal from the Antic piggyback, and even provided the extra signals that a U1MB requires. https://ataribits.weebly.com/blog/category/monster-600xl Although it did work, it only seems to like a small amount of Chinese Clone SD Cards I had purchased a few years back, and nothing else. Kinda funny actually, since it is normally the clones that are the problem, and not the solution. Once again it all comes down to timing, and because the stock 600XL uses a different glue logic vs. the 1088XEL, it was enough to cause issues with many of the normal CF Cards not working. Luckily I have 4 clone cards that work great in it, so I'm set
  12. Hi Doc In the beginnings of the 1088XEL development I remember running a series of tests with LS, HC/HCT, ACT, and F type 7408 chips which has one of its gates used as the phi2 buffer. If I recall the LS was actually a tad bit faster than the HC/HCT, which was enough of a difference to make or break certain timing aspects that were very important to PMG routines. The F series was just a bit faster still, and insured that all would be good. The ACT although better in speed and better in power consumption than the F, was actually getting to be too fast for our 8-bits, and was producing some big under and overshoots due to the ringing. Most likely with a better board layout this could be overcome and the ACT's would then be the chip of choice. Since so few of the F series are even needed, the extra power consumption really isn't an issue (one for the main board and 4 chips for the XEL-CF3). Thanks for your insights 👍
  13. Yes I agree, this could certainly be a big hit 👍 When I was doing a few mods to the AtariWriter 80 disk to enable the automatic 40/80 column video source switching, I also decided I needed a good readme file example that could be quickly loaded while I was testing stuff out. So what better than to write up a description of the new XEP80-II system as that example. So here I was actually using my Atari 8-Bit for the first time in well over 25 years to do word processing, and it was actually very enjoyable and absolutely great to see so much of the writing on-screen all at once. Then printing that to a PDF via FujiNet, it suddenly struck me that this was a very usable system to write stuff in Using the HDMI converter with the video source switcher was the icing on the cake, since it was completely painless to move from 40 to 80 columns, and back, with no more fiddling with the vertical or horizontal size adjustments of the monitor. What I'd like to see happen for the future of AtariWriter 80, is the incorporation of @phaeron's Ultra Speed Driver. This was beyond my Atari coding abilities. Also it would be nice to see a few of the quirks ironed out, such as the need to occasionally press break to reformat the screen when editing (although that's a minor annoyance), and to not have to resort to adding an additional blank line with return at the end of a document so that it can be smoothly scrolled up and down as the page transition occurs.
  14. There was a correction needed on an image download from my website. the image was a depiction of the specialized navigation keys triggered by the use of the ALT key in combination to add the ability to easily maneuver around the AtariWriter (Plus or 80) word processing program. This came about when i was testing AtariWriter 80 with my new XEP80-II board, and I was getting tired of having to memorize the odd key combinations to normally do so. Here is the corrected version. This is presently only available on the V1.7 firmware for the NUC TK-II. Eventually I'd like to migrate this over to the standard TK-II for use in all machines, but first I'll need to do some refactoring to make space for it. Other changes in the V1.7 Firmware... FIXED: When launching into FujiNet with Basic Disabled, the No Basic aspect wouldn't stick and still required holding the Option key (F4) to insure that Basic stayed off when loading a file. FIXED: A CTRL+SHIFT+A was being sent for clearing the keyboard buffer that was interfering with the AVG Cart. This has now been moved to occur very early in the process, so it should no longer be an issue.
  15. The first production board order was recently placed by @MacRorie, and he has a fully assembled prototype I gave him for evaluation, but not much time has passed on that. So I would imagine it'll take a bit more before the production wheels really start spinning. As for the case, I need to get back on that project, especially now that @Mr Robot released the 576NUC+ based blank STLs. I was originally working with an earlier STL that still had some stuff left over from the NUC, so I'll want to transfer over what I was working on to the new blanks, giving me a clean start. When I'm done and the new case has been test printed and proven out, then I will release the STLs for download, and The Brewing Academy will certainly have the actual 3D printed version available as well.
