I've checked my device and the VendorID (VID) is 0483 and ProductID (PID) is 5740. However, I'm still not convinced the problem is with the Vortex86 SOM. When I plug in my KVM it allows me to type a few characters and then displays the exact same message ("Internal stack overflow, System Halted"). …

Ugh ... Same problem. It reports "Retro wave device not found." and then a few seconds later "Internal stack overflow, System Halted" I'm also trying a separate power source: weeCee VCC -> N/C weeCee D- -> RW D- weeCee D+ -> RW D+ weeCee GND -> RW GND+weeCee GND PSU -> RW VCC PSU GND -> RW GND+ …

I'm glad to see the interest in the HDMI (or DVI) output since I have also looked into this and considered the LVDS->HDMI adapter but it would require a board redesign (weeCee) to provide the connector and then the additional hardware to convert it. I've also looked into other options for scaling …

Hmmm, it still doesn't work but I think the problem is between the Vortex86 (weeCee PC) and the RetroWave PotatoPi Lite. (ie. the RetroWave OPL3 is connected to the PotatoPi Lite) As I mentioned, when I plug the PotatoPi + OPL3 into the weeCee, the PC immediately reboots. I've tried using a USB Y- …

Ahh, OK... It sounds like the AXP version will have more features (ie. added serial port). I think that's the version I ordered PCBs for so I'll keep an eye on the project and order parts after everything is finalized (and hopefully the PCB doesn't need to change). Thanks much!

Rasteri, do you have a BOM for the projects? Also, what's the difference between the two versions of your project? It looks like one outputs the mouse over serial and the other is over PS/2? What about the KBD?

How accurate is the Sound Blaster support on the Cirrus Logic CS4237B chipset? I'm not talking about the FM synthesis (OPL emulation) but the DSP part of the chip. If I understand correctly, a Sound Blaster is basically FM + DSP so I'm wondering about using an Adlib (or OPL2LPT/OPL3LPT) + CS4237B to …

Did you try without unisound loaded ? I've just re-tested it without unisound and it still has the same problem: When I plug the RetroWave into the weeCee USB port, it immediately reboots the computer. (I'm using a 4 amp PSU so I don't think power is the issue) Afterwards, if I try to run RWDDOS it …

OK - I'm trying to run VGATV on the "weeCee" (Volaris Z9s chipset) and it detects the chipset as Tseng Labs but it the OSSC reports the signal as 263p (31.54 kHz, 119.93H) (using NTSC command-line option). If I try to play a Sierra game (ie. PQ1 AGI), the OSSC can't sync. The OSSC LCD flashes …
