Checking back on the order page in PCBWay, the plates ended up 1.6 mm thickness (I just sent the gerbers as is from Andy's stuff). I'd definitely try something like 2/3rds or half of this easily. It'd be interesting if Andy aka TheRasteri did something special to his order with regards to the …

Thanks very much. Are there any specific instructions when ordering the PCB? (surface finish, spacing, hole size, etc?) Nah, not really. Default options on most board houses should suffice. Well maybe pick the appropriate soldermask colour for the front (blue) and rear (black) plates, or different …

Have the final gerbers been released? I see the shared project on PCBWay but I'm not sure if it's final (ie. no bodge wire?) and I'd like to compare prices with JLCPCB. Also, where can you purchase the VorteX86 module in the USA? So far I've only received a response from WDL Systems ($183.00). …

It's a TD3088A-based board. Looks identical to this one : http://www.vgamuseum.info/index.php/cpu/item/ … amarack-td3088a Maybe the ISA bus on my athlon machine (KT133) is crippled somehow

You weren't joking about the hercules mode requiring a fast processor. My fastest two PCs with an ISA slot - Athlon XP 2800+ and Pentium 4 2.8GHz - get 18.052FPS and 27.129FPS respectively. Awesome work though 😀

Would you mind sharing the gerbers for the aluminum case sides? I tried to generate them from the circuitmaker even following PCBWay guide but I have no idea what I am doing and can't get valid ones to generate. Yeah Circuitmaker is totally broken since the 2.0 update, I'm in the process of …

2) it gets proper power for an interval of time before it lowers back; isn't that that indicative of a capacitor that can't hold its normal value of charge, tries to rise to it before a short happens? No idea if that is a regular failure behavior. They don't teach these things in college …

Yeah the VREG is a 3.3v one, it powers the SD card and the pullups on the ethernet port. If it was broken the SoM would still likely work. I would say triple-check the soldering on your SoM headers, perhaps when the SoM is connected it's causing a short because of a mis-soldered pin. BTW update …

Edit2: after reseating the SOM for a couple of times, I get a bright blue led again, but the voltage goes between 4.40 and 4.80 (jumps around periodically), even under minimal load (no ps2 peripherals, no vga, no network, etc) Does the SOM work in your other board? Just trying to narrow it down …

So I think I'm going to recommend people use a 16KB eeprom (24LC16 is what I used) then they can just use the Orpheus flashing tools. Note that you need to edit CSMPU330.ini to enable Adlib - add the text "IFM" to the GlobalConfigBits field (so it ends up being "GlobalConfigBits = IFM SPS WTEN" ). …

Yeah it's not a cheap project (especially in Canada, apparently) but if someone wanted to manufacture these in quantity the price would come down significantly. I'm just a hobbyist really so I'm not the person for that job. I do have a cheaper Vortex86 SoM (the SOM-128-EX) but I'm burned out on …

Yeah it's fun to get MS Network Client working just for fun but it's pretty rubbish for actually transferring files, pretty much every time there's a new Windows update it breaks something. The ODI ones are what you want for network gaming

Can you increase the I/O recovery time on that machine? Does it make any difference? That doesn't seem to work either, unfortunately. I've fiddled with all the other PnP/PCI/ISA settings I can in the BIOS and nothing makes a difference. TBH at this point it's pretty academic, I figure everyone who …

Hostload works perfectly on my Vortex86 SX motherboard and PC/104 CS4237 soundcard. As there's basically no difference between the PC104 board and my carrier board for the Vortex86 DX SoM, I'm beginning to wonder if there's something weird about the DX variant when it comes to ISA. At least it seems …
