Yes that another option. The made a universal retro PSU as external brick which is the same for various older home computers and just supply a different connection cable from it to the computer. For this one you rewire the transformer plug to go directly to 4 pin molex inside your ti99 and remove the old power supply totally. If you want to keep your ti99 power switch and led you have to figure out your own solution for that part. Finally, once your ti99 is modified internally you got to be careful to not plug in an original ti transformer again or it will damage your console.

Easy to build a new one. You can just wire up a bunch of 1% resistors in the right pattern to the PIO connector.

Yeah that one thing I noticed with them. So what external 12volt power supply do you recommend? Is there a suitable one like on Amazon?

Yep, maybe now someone will make a small PIO board or adapter for the open-source Covox devices, and update the source code to support SAMS, or I will myself at some point, but now its all there to play with, hopefully someone finds it useful!

Digi-Port - The Sound Solution AUDIO-BYTE v1.03.9109.14 (BETA VERSION) (c)1991 By Oasis Pensive Abacutors and Western Horizon Technologies Originally, sold by Western Horizon Technologies, was a small hardware device that plugged into your TI99 PIO port which allowed you to play the '90s PCM 8-bit sound file format found on the PC, Amiga, Atari ST, Mac. Now, here is the TMS9900 Assembly Language Source Code release of the BETA VERSION which Oasis Pensive Abacutors wrote as test software for the device back in 1991, I don't recall there being another version released back in the day, there might have been, but anyway here is this version that makes use of the 32k (for short 10 second files), or expanded 128k VDP, or Rambo and Geneve memory for much longer. You can also play the sounds via the TMS9919 chip, but not as well, the sound quality is less, but it is easy today to build your own Digi-Port hardware device, see these pages for more info: * https://en.wikipedia.org/wiki/Covox_Speech_Thing * https://github.com/necroware/silly-sound-bastard GITHUB Release Link: https://github.com/gary99opa/Digi-Port DIGIPORT.dsk DIGIPORT-Sound-Samples.zip DIGIPORT-Source-Files-Only.zip DIGIPORT_1_03_GaryOPA_05_09_2024.zip

I been reading thru this thread @speccery and I was wondering if you have any strangecart boards available, and if possible would you be willing to ship one to Canada and for what cost, I love to see how it works in person, and possibly use it for some of my own cartridge software projects I been working on. Thanks.

Good idea. My original Phoenix logo that has various frames with it moving was all done by hand on various layers of graph paper, with space at the end for the hex numbers and thin enough i could do a new layer on top seeing where my idea of pixels were below on the previous frame. of course now there is actual programs that can do this for you, i think even one on the PC. I forgot the one for the TI that works well. But sometimes nothing works better for your human brain that picking up pencil and laying things out by hand. And of course can help if you sketching over actual printed object to convert it to pixels.

Yes. There seems to be a template that helps to generate fake Lego box artworks, as I seen many various cool LEGO sets that don't exist.

Thanks. I will check it out.

Sounds good to me, would not mind a PCboard up here in great white north, I will throw some beers into the snowbank to kept them chilled. Any thoughts on what type of regulated 12v DC power brick to use it with as this only supplies the clean 5v and -5v you still need an external steady 12v DC power to run it. But it would be nice to see a usb c version that runs off a a good 2amp charger.

I am game. What are the rules? Length of demo? Hardware allowed to be used? Original stock or upgraded with mods? Emulators allowed or not?

Could be I attended the Ottawa fairs and user group meetings on regular basis even tho I was in Toronto they had a stronger group and would organize fairs. The 9t9 one in Toronto never did got some reason. If you have any photos from back then would love to look through them. Out of all the fairs and shows I attended there not much photographic wise of me, many others but I only see two photos of me taken from shows, wish I could find more as I have no personal photographics at all before 2008.

Yes, I remember seeing it mentioned here. There is GitHub link it looks like from the photo pasted here but it's too blurry to make out, plus it's produced by oshpark so most likely can order the PCboard yourself and the parts list from GitHub and build one yourself and might end up a bit cheaper overall if you making a few together.

I see it before. But the cost is crazy. I thought about it for one of my silver/4a as the power supply is getting super hot and causes freezing after 48 hours running non stop, but comes to almost $150 cad with currency conversion, duty, taxes, shipping. I can buy a whole unused /4a console for that price.

I wrote one graphics demo for v9938 that goes through some of the built in commands they 38/58 offers for drawing boxes, lines, scrolling the screen, etc.

And I might have to fork out for a f18a myself as well soon.

I played a good one on mobile. Of course the longer screen helps. But it did like a preview fast scroll up when you are aiming. Similar to how some golf course games do when lining up a shot showing you the fairway ahead of you. The v9938/58 had feature to allow bit scrolling up but never was used on the ti99 but I think the f18a could do it well also.

Has anyone tried converting it to compiled basic?
