Anyone know what the RJ11 port on the side of this Belkin F1D066 KVM is for? Its not mentioned at all in the manual. I would assume remote triggering but how would I use it? Thanks

I have 3 T4400 power supplies that I'm troubleshooting after replacing all the caps. I get enough life from them to get blink codes ( variously related to memory initialization) I'm hoping someone could enlighten me as to the pinouts. I know the obvious voltage related ones but I'm clueless...

Ok, so I managed to get life, but Im just getting blink codes from the battery light. They are , variously depending on different factors hex. Bh, 15h, 7h

I did some basic meter stuff on the mosfets and none of them appear shorted and only conduct between 2 of the pins in only one direction. The big chip on the board is a microcontroller with prom. If it's hosed I'm out of luck. The battery prongs take current when they are given voltage. I...

I used flux remover and then some isopropyl. "It also looks like there are some custom hybrid modules used." Can they be decapped or depotted?

Here are photos of the front and back. I have a reflow setup and most testing equipment up to a scope if you have questions.

That's the big one though. We are extremely lucky if we find a schematic on any of our equipment, even when it was new. That aside, I recapped the board and all the 1000uf's were leaking. Traces under all look good. Still no life from the module though, and no current draw when trying to...

I got a few t4400 laptops as parts machines. I hook them up to 21v and they draw 0 power. Even when I hit the power button, nothing. Are they toast or can the caps cause this?

What exactly do the Receiver and Transmitter cards do? Signal Amplification? Buffering? What if a ribbon cable was used instead of a round one? I've seen ISA extender cables, what is the limit to how long the cable can be? Also, I believe Sergey's backplane only has holes for ATX.

I'm looking for the dip switch settings on a Kurta IS/one 12 inch digitizer. The same one in this video. All help is appreciated. Thanks

I've heard tell about Windows 3.1 systems using browsers that start to have issues.

Do you face any risks hooking up vintage gear to the internet?

I have managed to find a photo of the card. Here it is in all it's glory. Way more populated than I thought.

Unfortunately no. The correct one has simms as well as cache chips(required).

After spending an hour on Usenet(Google groups) I have discovered the part number for the Everex step 386 memory Expansion to be EV-1817. Maybe this will be helpful to someone else. I doubt I will actually ever find one.

Does anyone know if there is a way to tell if the HDD controller is installed without opening the machine up?

A manual set sold on ebay in July, so they exist.

That link is dead now. For a site that is for vintage computing they certainly have a hard time maintaining link standards.

I have an st-05x board
