I did this same mod on the same aopen cobra card, but only soldered on the SBLink header, not the resistors. It seems to work perfectly. Is there any concern with not populating the 10k ohms for R49 and R50 ? This card is amazing.. perfect for my DOS/win98 rig!

Just wanted to confirm that the remote control doesn't seem to work with VXD drivers, but does with WDM driver. Verified today with Windows 98se. Too bad!

Ah-Ha... so what I've discovered is that long traces themselves seem fine, but there's those little "resistors" (thicker black lines) at each key.. right by the key's circular pad. All the bad keys seem to have much higher values. For working keys, I'm seeing 13-20k ohm For broken keys I'm seeing …

Of course why didn't I think to test the keyboard as is. Silly me, I'll do that first and see if the keys are still bad. Appreciate all your repair tips! I'm still worried I won't have enough plastic to secure the board. Some of it came off with the iron. If that's case, is there something else I …

Okay so I used a soldering iron to melt the plastic bits and separated the keyboard. There was a bunch of gunk on the right side of the plastic sheets so I cleaned that all up.... but I'm having trouble putting it back together to see if it works. I tried my best to keep the pegs intact, but isn't …

I followed the ifixit guide and was able to take it all apart.. you're right about the brittle plastic though, I had a small tab break off, but it all closed nicely and didn't seem to actually hook to anything. I didn't notice any leakage, cmos battery looked fine (and actually holds charge). Caps …

WOW... this is incredibly informative. Thank you SO much! I think I'll try what you suggest; see what I can do to take apart the keyboard and fix it. If I can't fix it, try to keep an eye out for parts model. If that fails, try this dock mod or find one with PS/2 support. My bad keys seem to be: 8, …

I recently picked up a Libretto 50CT laptop. A beautiful device!! It works fine, except it has issues with the keyboard. Most keys work, but some are "finicky".. like pressing ENTER does nothing, but if I press SHIFT+ENTER it works. RIGHT arrow doesn't work at all So I took it totally apart and …

Thanks for the suggestions @darry! I tried few things, and here's what I found: 1) Bret Johnson's USB DOS tools are very impressive. Unfortunately I could only get a few of my USB controllers to work, and none that I would want to use for gaming. PS3, PS4, PS5/dualsense, Xbox one controllers, 8bitdo …

Is this possible? Or does a USB/BT->gameport dongle exist, where you pair with the dongle and it converts to GamePort ? I would love to use my PS4 or Xbox one controller in DOS games (ex. duke1, apogee platformers). Finally, if pure DOS isn't possible, perhaps through Windows98se, DOS games? I'm …

I just tried manx's BLASTOR.EXE and indeed, this AOPEN "sb pro 2.0" clone does not mimic the PCM reversal, and thus outputs to the wrong channel. OPL stereo is perfectly fine.

Before I flashed powerleap3 I took a dump of the existing BIOS from my Gigabyte GA-6BXC motherboard (bought off eBay). Oddly, the BIOS screen claimed it was v. F3, however I found it does not match any existing v. F3 BIOS out there. I'm uploading it here for the sake of preservation.

I moved from a v.F3 bios to powleap3.bin and holy what a difference. Now it actually reads my Via C3 type/speed properly, bootup is crazy fast, no mem check, more bios options (better boot order config for example).. and no more random crashing. Thanks, and thanks gerwin for linking it.
