Just finished all upgrades and work that I had to do on my Toshiba T3200SXC.
Here is the overview video: https://www.youtube.com/watch?v=WX30t3lYezs

Now it has:
- an internal Wireless LAN + USB storage ISA card (ethernet card with OpenWRT module and SMB server for USB)
- WPA2 network scanning and connecting from within the MS-DOS
- Internal stereo speakers
- New DC-DC power supply, which can be powered from USB-C powerbanks
- Replaced LCD screen
- Replaced lithium battery
- MS-DOS 6.22 + Win 3.11 with boot menu properly set up
Old power supply and new (smaller) custom power supply:

This is how the network card looks like. The base is a generic NE-2000 compatible card. Currently it works in 8-bit slot, so it might even be XT-compatible. The bracket is 3D printed, not only to hold the wireless module (A5V11), but also to let the wireless signal go inside (metal bracket obviously would not work). +5V power is stolen from the ISA card via two wires soldered to GND and +5V pads, with a 500mA polyfuse in series.

Here is USB drive accessed as a automatically mounted network drive in Windows 3.11. It works in MS-DOS too with MS Network Client software. Reading, writing and execution works fine.

Wi-fi scanning and connecting works fine from pure MS-DOS with some client-side and server-(OpenWRT)side scripts. I can even pair this laptop with my digital camera, which currently has no use, but looks fun. I probably could even take some photos and download them by sending proper HTTP requests.

I need to put together the instructions on making such an USB+WiFi ISA card and configuring OpenWRT properly. Probably will post that in a separate thread when it's done.
