Hello everyone, I'm a bit curious about something and I haven't found much information on the internet, so I thought I'd ask here to see if anyone has any idea. I have a couple of computers that use SBCs on ISA blackplanes, mostly 386 and 486 computers. I noticed that there are some backplanes with …

Fair enough @keenmaster486, If I could have the VB code just so I have an idea/starting point. I haven't had much experience with VB in my life, especially when it comes to doing networking stuff. Thanks!

Hi! I wonder if you still have the source code for the Windows 3.1 app, I wanted to play around with it, but the link seems to have died. Do you still have it?

Hi @whitepawn, I think @snufkin solved it. I can't find a revision number on the board though. Hi @snufkin. I think it's all solved, I'll give it a full test later!

I will probe it with the multimeter tomorrow and put my findings here. Thanks for the help! Yeah, J1 goes through R24 (220 ohm), so that could be an LED output. JP2 pin 1 looks like it goes through R27 (330 ohm), with JP2 pin 2 going through Q1 to ground. So could also be an LED output controlled by …

Thanks for the response. I'll try to probe it with my multimeter later tonight. In the meantime, here's a photo of JP1. WhatsApp Image 2022-01-26 at 11.24.53 AM.jpeg From the back it does look like it's connected to a resistor: WhatsApp Image 2022-01-26 at 11.24.54 AM.jpeg JP2 looks like it's …

Hi Everyone! I have an a 486/5x86 SBC, it looks the same as the one from this post here ( https://www.vogons.org/viewtopic.php?f=46&t=80048&p=1036738#p1036738 ). Mine is not labeled PC420-G2 though, instead it's labeled 486/5x86 SBC Ver:GC. It seems like it's the exact same one from this site: …

Hi Whitepawn, I have the same SBC. Have you figured out how to connect the HDD LED, POWER LED and RESET button? I can't find any documentation on this thing. Hi, I couldn't help myself and bought another single board computer which labeled as PC420-G2 by protech company. Here is SBC page in 1997: …

Yep, I got my CF card and no luck. The still gives me a blank screen. At this point I'm giving up, I have tested multiple hard drives. Unless I need something in the file system for it to be detected, I don't think it's working.

Yeah, sadly it didn't work with my msata. The led in the msata turns on and the hard drive led on the laptop stays solid green but there's no sign of life aside from that. I'm hoping the CF card solves that. Edit: I got a hard drive from another toshiba laptop and no luck. The hard drive turns on …

I have ordered a CF card and the adapter to test it out, I'm still going to try to find a hard drive in my garage. I have a 32gb msata drive and an adaptor I can test, I'll report back.

It could well just not like the adapter, do you have an IDE drive to test it with? It's certainly normal behaviour for my 110CT when there's no hard drive in it or one it doesn't like.
