Gigatron Hackers

Awesome stuff!

Another update, I have added Bullets; 4x4 user definable patterns that use XOR to draw and restore, (all the usual caveats apply when XOR drawing).

Reading your page3. It seems that the Bcc instructions no longer need three bytes (e.g. BEQ = 35 3f xx). One can get the same effect without the 35 prefix. Yeah but that would break compatibility unfortunately. Also a question: PEEKX/POKEX do INC or INCW after peeking or poking? PEEKX/DEEKX are 30 ...

Can you get your hands on a CRO? You'll probably need to diagnose the actual CLK waveforms. Another thing I would do is to inspect for physical damage to the PCB and more sensitive components like the diodes using a magnifying glass or digital microscope. An abrupt force from falling is likely to ov...

Thanks at67, that did it. 8-) If you exit the emulator mid upload to the hardware, then that is a guaranteed way to get BabelFish out of sync with whatever tries to talk to it next. The upload process in the emulator is handled by a separate thread, so it's very easy to exit whilst a long upload is...

I am trying and failing to use gtemuAT67.exe's "download to HW-Gigatron via right click .gt1 files in its file browser"-function with Pluggy reloaded. First question: Is this a supported function of gtemuAT67.exe v1.0.9R (Windows 10)? Yes it is. If yes: I tried to use Babelfish from Norgates Gihub:...

if i use 74LS logic what crystal should i use - 8mhz? Most people who have overclocked with LS/HCT have gotten to around 8~9MHz. if i use 74HCT can or should it be 10mhz? Not sure you can get to 10MHz on HCT without some other changes to the clock circuit and possibly the diode decoding matrix, (th...

Yeah ! it speed up ! How can I compile my gtBasic code ? Is it commande line ? You can compile from the command-line, there is a at67/tools/gtbasic/gtbasic.exe command or you can press CTRL + B and navigate, (left click on folders), to your *.gbas source code and then left click on the source code ...

Add the path to SDL runtime library to the windows path in order to be able to run gtemuAT67.exe; You can also just copy the SDL2.dll file to the same folder as gtemuAT67.exe , that way you don't have to modify your Window's path, but either method is fine. Run manually the gtemuAT67.exe found in a...

Thanks ! I guess it was included like the TinyBasic. I tried to compile under Windows without big success as with Linux. I've downloaded cmake and added it to the path. I've downloaded sdl2 binary and sdl2 sources in separated directories. But I don't know how to configure cmake to find libs, the "...
