A lot of cases used the max height spec for the PC/XT which is shorter than that of the PC/AT

That's correct - don't mess with H. Lin(earity) you will just warp the picture. H. Frequency is what you want. The linearity coil is a ferrite core adjustable inductor which is typically set and glued in position. They are easy to damage

I have a Pentium machine connected to the HD15 input of the Extron with a standard VGA cable. I have the R,G,B,S output connectors of the Extron connected to a BNC to HD15 converter, that is itself connected to a VGA 15-pin to VGA 9-pin converter through a gender changer, that is connected to the …
Re: Anyone have AT form factor specification?

I don't think any of my AT-style systems have the DIN exactly centered in the hole. It seems the spec was pretty loose on this

Your unstable picture looks like the horizontal oscillator is out of sync. The nominal horizontal scan rate for the 5175 is 30.5 kHz, whereas VGA uses 31.5 kHz. You likely need to adjust the horizontal oscillator in the monitor to be able to capture the 31.5kHz signal using the "horizontal hold" …
Re: Think I got a faulty gameport y-splitter

My guess is the second pad is not getting +5VDC. Most joystick splitters would have been designed for analog sticks which don't require power for the axis like digital gamepads do

Does your system offer separate settings to shadow the system and video BIOSes, or is it all or nothing?

At this point I trust the Chinese government more than the US government to be honest, which isn't a high bar though 🤣

It sure seems like you guys have shit luck with power supplies. I have a fleet of like 10 AT PSUs from the 90s that all run like raped apes. Some I've recapped some I havent, all been checked for ripple with my scope and perform well. Now early 2000s ATX supplies are another matter entirely...

There is a bug in 3C5X9CFG if the card does not support plug and play or full duplex. Toggling the transceiver type will cause those fields to appear but they have no affect. In your case, since the fields did originally appear before your issue, I would suspect a hardware failure on the card …

Same type of KBC was used from the original AT to the late pentium era. Not really 286 specific. It's just an Intel 8042 uc with a ROM burned to it
Re: Good news everyone! A new mTCP is available! (2022-07-01)
Posted on 2022-07-18, 01:18
What router/DHCP server is this? I really need a proper bug report with a packet trace to tell you what is going on. If your router is doing this, it seems like bad behavior but it is not really affecting anything. None of the mTCP programs use the hostname field. It is just a request to a DHCP …

My dual voodoo2's are in a dual pentium pro 233 system. Happy with it, but 266 would offer a little more headroom
