Yeah ! it speed up !
How can I compile my gtBasic code ? Is it commande line ?
PS : unfortunately my Gigatron fell on the ground in his case and does'nt work anymore. Power led is on and stable but the blinkerled are off (sometimes 1 or 4 briefly light when powering on).

Re: Where to find gtBasic emulator
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 within the emulator.PhaustSceptique wrote: ↑10 Apr 2021, 12:55 Yeah ! it speed up !

- Re-seat any socketed chips.
- Check for a stable 5V rail.
- Check for a healthy CLK.
- Follow the trouble shooting guide in the manual.

Re: Where to find gtBasic emulator
- socketed chips re-seated !
- 5V is stable !
- CLK1 = 1.44V, CLK2 = 1.54V;
- I checked pins soldering but I will do once more later if I have no solution;
- I tested each pin relative to excel file : diode mode pin check is ok but voltage mode is not. Here the differences :
Code: Select all
Pin |U1 |U3 |U4 |U5 |U6 |U14 |U39 |
1 | | | | | | |2.8 / 0.9 |
2 | | | | | | |2.8 / 0.9 |
3 | | | | | | |1.46 / 1 |
4 | | | | | | |0 / 0.7 |
5 |1.44 / 2.5 | | | | | |2.2 / 3 |
6 | | | | | | |2.14 / 0.7 |
7 | | | | | |3.98 / 4.6 |0.4 / 0.6 |
8 |1.48 / 2.5 | | | | | |0 / 0 |
9 | | | | | |3.5 / 4.5 | |
10 | | | | | |5 / 4.8 | |
11 | |2.5 / 2.4 |0 / 2 |0 / 0 |0 / 0 |3.6 / 4.6 | |
12 | |2.48 / 2.4 |0 / 2 |0 / 0 |0 / 0 |5 / 4.9 | |
13 | |2 / 2.5 |5 / 2.4 |0 / 0.2 |0 / 0 |5 / 2.3 | |
14 | |2.44 / 2.8 |1 / 2.4 |0 / 4.8 |0 / 0 |5 / 4.8 | |
15 | | | | | |3.9 / 4.2 |2.5 / 1.2 |
Re: Where to find gtBasic emulator
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 over-stress some of the more delicate stuff.
I'd supplement this by turning power off and just doing continuity tests on every track and across every diode, will take a while, but will eliminate a lot of possibilities.
