[@lukhash]

Great presentation Travis. I'm loving my TeensyROM!

[@TravsterOR]

Thank you much LukHash! Love your music, and glad you're enjoying the TeensyROM! 💜

[@C64EVO]

A brilliant presentation and an amazing feature set! Congrats on all you've accomplished. We love our TeenyROM!

[@TravsterOR]

Thank you for the kind words and for all the EVO team has done in support. You guys rule! 💜

[@theoasisbbs]

TeensyROM is on fire Travis!

[@TheSunnyvaleTrailerPark]

Your audio sounds perfect! What brand of headphones are you using there mate? ✌️🇦🇺

[@TravsterOR]

Thank you much! I use Logitech headphones for voice, the C64 audio is direct.

[@igork3522]

Great presentation! Cannot wait to receive it. Thank you for your hard work.

[@TravsterOR]

Thank you for the kind comment and your order, much appreciated!

[@StatMatsVidz]

Excellent presentation Travis, you did really well! And great to see OneLoad64 in action along with the NFC loader. The TeensyROM is definitely the best featured C64 cart imho. :)

[@TravsterOR]

Thank you much StatMat, you know how nervous I get. ;) Indeed, OneLoad64 is the perfect collection! Getting to be that time of year again, can't wait for the next release! :) Joery mentioned you in the interview portion, and what a nice guy you are, to which I fully agree. You seem to know everyone in the scene!

Hi ! Just ordered my TeensyROM a few days ago and I'm very excited to discover it ! Keep up the good work! Thx from France

[@TravsterOR]

Thank you so much, can't wait to see/hear what you do with it!

[@erebos007]

@TravsterOR I really want to build an NFC reader with some good looking cards like you described in another video and I think a "carousel" front-end in the like of the TheC64 would be awesome but I don't know if it's possible nor if I'll ever have the skills to do that. 😁

[@TravsterOR]

@@erebos007 I'm not familiar with the carousel front-end, but in a quick search, it sounds somewhat similar to the TeensyROM Desktop UI by @hExx, check it out here: github.com/MetalHexx/TeensyROM-UI There's also a link there to a great demo video showing it's features. Regarding NFC, there are a couple places selling readers/card/cases, but it's fairly straight forward to do yourself, details can be found here: github.com/SensoriumEmbedded/TeensyROM/blob/main/docs/NFC_Loader.md Just let me know if you have any questions, or on the TeensyROM Discord. Thank you much!

[@erebos007]

@@TravsterORThank you. I'd like a front-end running on the C64 not a PC side UI. That would be great and maybe the TR running as a coprocessor could make it possible, I don't know how it's interfaced with the VIC-II. But if it's possible to display text and a little picture side by side and that we can scroll to the next entry maybe, idk😁

[@TravsterOR]

​@@erebos007 Interresting thought. @StatMat has paved the way by including C64 display compatible images in the OneLoad64 collection. Adding that it to the potential future ideas list, thank you! :)

[@AppliedCryogenics]

Does the Teensy have a way to offload the bus interface to some peripheral so the CPU doesn't have to continuously poll GPIOs?

[@TravsterOR]

Yes, basically, but not via an external peripheral. An interrupt fires each phi2 cycle and it checks to see if the transaction is for it to service, or immediately return control to the main routine/loop.

[@kd5inm]

Can the Teensey Rom access a usb hard disk? For instance in stead of a usb or sd card?

[@TravsterOR]

Interresting. Had to research some as I haven't been asked that. It appears that the general answer is no, but there are some reports of SSD/USB adapters working with Teensy: forum.pjrc.com/index.php?threads/usb-host-and-ssd.71398/ I don't know of anyone who had tried on a TeensyROM, SD/USB sticks have been large enough in my experience. Thank you!
