Re: Explore the Gigatron music engine, using GLCC

When the Gigatron audio channel uses only one channel (any of the four channels), and only the square wave is used, the wavA will be able to control the volume of the square wave, in the range of 64-128, with decreasing volume. You can also use wavX to introduce random noise or effects at 60Hz, (ve...

Re: SDCard browser for Pluggy Reloaded:

The makefile from https://github.com/kervinck/gigatron-rom/tree/master/Contrib/at67/gbas/apps/Browser_SDCard is needed to build the .h files needed for making the arduino code (both ROM and NOROM), but what about the makefile needed to build the sdcard.rom file to be flashed onto a 27C1024 EPROM? W...

Re: SDCard browser for Pluggy Reloaded:

I'm adding some optimisations to the Browser this weekend, so the ROM and NO_ROM versions will be getting another update. I'll update this thread, the DropBox links and the main repo when it's done. These new links will supersede all other/old links. The browser did assume that NextByteIn_32 would r...

Re: That Addictive Word Game

Looks like a great candidate for porting to the Gigatron, either through 6502 emulation or using vCPU etc.

Personally if I had time I'd love to code it using gtBASIC, but I don't unfortunately.

Re: Dead pixels / solved

Yeah I take back what I said, in Discord about a year ago those same black pixels were seen by others in the same positions. This was my best guess back then: the screen corruption is most likely the SDCard handling code for the unfinished expansion card Marcel was working on, there are a number of ...

Re: Dead pixels / solved

Much more likely that your ROM was not burnt completely correctly, (verified), or had not been erased fully before programming. Re-erasing and pre-programming it with DEVROM probably just overwrote a bad ROM image with a good ROM image. I have never seen ROMv5a exhibit artifacts like that in emulati...

Re: Roadmap and status of Gigatron TTL

The maximum download speed is 3900bytes/s and maximum upload speed is 7.5bytes/s for any of the Arduino solutions, (including Pluggy).

I just realised you probably meant bits per second, so same answers :)

Re: Roadmap and status of Gigatron TTL

I'll add my 2 cents: - IMHO everyone is free to do what they want, do whatever you like with the Gigatron and share, (or don't), your findings, musings and results with others here on the forum. - Whatever motivates you to have fun or to learn with the Gigatron, do it, I think that's what Marcel wou...

Re: how to burn in a 27c1024 EPROM a single .gt1 file

Can invader.gt1 be trasferred to a real gigatron using sendFile.py from a PC? or too big? It transfers fine to 32K RAM hardware, the same as PucMon. The glcc c compiler does work with roms v3, v4, v5a (does existst v5?), what are rom versions ROMvX0 and romAT67x? ROMvX0 is a ROM I have been working...
