Re: Gigatron Clone Ideas

Schweet! Fixed the FPGA code by adding if(cu_pl_n) to the PC increment. Tested on ROMv3/v4/vX0. (Love those DIP switches!)

Re: Gigatron Clone Ideas

Sounds consistent with the two known failures we've been talking about.

Re: Gigatron Clone Ideas

https://forum.gigatron.io/viewtopic.php?p=2301#p2301 Hmm... Looks like exactly the same thing. I haven't seen this myself, though I have had other strangeness happen specifically on ROMv3 Pictures when it showed Jupiter. Are Blinkenlights still running? I assume that you already received your Famico...

Re: Would emulating vCPU on a Propeller 2 be feasible?

I've been toying with that idea too. The 8 PIOs offload much of the serial data manipulation from the main dual core M0+. It's crazy when you think about how much processing power you get for $4.

Re: Gigatron Clone Ideas

Congrats! I'm curious... what make/model RF modulator?

Re: Not sure what to do with pluggy reloaded

Answering your PM in this thread. The syntax for using sendFile.py is in the python3 script itself. I found this thread using the search function for "sendFile.py" https://forum.gigatron.io/viewtopic.php?p=3147#p3147 The truth is I only used it one time and haven't looked at it again since...

Re: Not sure what to do with pluggy reloaded

I guess I missed the part where you're not actually using a Pluggy Reloaded and don't have an Arduino Pro Micro. If you're not comfortable with Arduino coding, IMHO your least painful route would be to use a Pro Micro since you wouldn't need to edit any code (it's the only one that supports SD card ...

Re: Not functional; Blinkenlights static

5) All 7 resistors can be measured in system without desoldering (with 5V power disconnected).
R3/6/7/10/19 = 2.2k
R1 = 1M / R2 = 1k (that said your clock waveforms in #1 look OK, so measuring R1/2 is purely an academic exercise)

Re: Not sure what to do with pluggy reloaded

Measure 5V on the pluggy reloaded header. Make sure you have at least 4.75V otherwise you need a better USB cable. The tinyfont files generate the fonts for the text you see within the CTRL-F2 menu. You shouldn't need any special files on the SD Card, just the gt1s that you are trying to run from SD...

Re: Not functional; Blinkenlights static

5) Also check the value of R3/6/7/10/19 . They don't look right and will affect PL_B/PH_B/Audio DAC operation. While you're at it, check R1/2 as well. I can't really read the colors from your photos but they will affect clock oscillation.
