I don't know a ton about how EGA compares to VGA and SVGA, but I was under the impression that there would be differences, at least when comparing monitors? I could be wrong though. I'd actually like to be wrong because that would mean having one less thing on my pipe dream wish list.

In my experience, there isn't anything particularly novel about EGA monitors by themselves. An old CRT monitor with a VGA card running an 16-color EGA game will yield the same experience.

Though EGA monitor can be used with Tandy computers, which makes them handy to have for that reason.

IMO it gets it's "Least worst PC video standard of 87-88" title by having better colors than hercules, and better text and resolution than CGA.

IMHO, 16-color graphics was pretty solid for the time. It was a significant step up compared to CGA or monochrome.

There is some amazing EGA art used in games. I'm still in awe of the Sierra games of that era and how they used dithering to create some impressive art with so few colors.

Actually, for real EGA experience you need an ega Monitor that can take 15khz and show 320x200 pixel perfect without scandoubling.

Thanks for looking into that and all the info on NT 3.11 with this board.

I might do a stand-alone test install with another G7S620 board to see if it's worth putting on the main build.

Yeah, that's why I use a dedicated, but still fully compatible graphics card with NT 3.1. I have a PCI Cirrus Logic GD5446, a PCI Tseng ET4000, and a PCI S3 Trio64 all fully functional with NT 3.1 drivers. My personal favorite with NT 3.1 is my Compaq QVision 2000+ based on the Matrox Impression Plus chipset. I added a 2MB memory module to bring its total video memory to 4MB. High colors and high resolutions look great in NT 3.1 (it probably doesn't deserve to look that good 😀 )

In the mean time, I need to figure out if I can get Windows 3.11 to run at higher than 60 Hz.

Unless you can set your graphics card's refresh rate outside of Windows using a DOS TSR, I don't think you can adjust the generic VESA driver from Windows 3.11. If you're looking for a graphics card with drivers that support higher refresh rates, I'd recommend a Matrox card up to the G400. Matrox has high quality Windows 3.1 drivers, and the drivers support a large number of monitors with particular refresh rates. If the driver doesn't include the refresh rate you need, you can even specify a custom image signal by editing the MGA.MON file (it just contains text) provided that the card's DAC can handle that rate.

I just did a quick scan of the MGA.MON file from my Win 3.11 install, and it looks like the highest pre-defined non-interlaced refresh rate is 85Hz with most Matrox cards.

Apparently, the cards are limited by both the DAC clock and the memory clock (which impacts the pixel clock) according to the instructions in the MGA.MON file.

Repaired the input solder joints on a 1084S. It had a problem where if the input cord was wiggled the image brightness would be reduced by probably 50% until you wiggled it a bit.

I think this is the reason I got it so cheap, it’s in practically perfect condition otherwise, so I think the previous owner thought it was just dark but actually it was just bad solder joints.

I fixed that problem but it turns out there’s a bad cap somewhere near the flyback also causing problems. I’m not a fan of desoldering the metal ground plate on the bottom of the analog board, but hey what can you do.

Finally put the Thorton 2400+ to rest from the Soltek SL-75FRN2-RL, and upgraded to a mobile 2600+ Barton.

Still dunno how to fix that "Unknown CPU Type" string but as long as CPU-Z sees it properly, I'm happy enough.
If anyone has a suggestion on how to fix that string (and on a nForce 2 mobo no less), I'm all ears!

Yeah that's what I'm saying. There will be some arguments about aspect ratios, but there always are, even with VGA stuff, and my answer is the same, "You got what you got" on the screen of older monitors, within your tolerance for twiddling the v-size/h-size knobs to something different for everything or just leaving them in a compromise setting that gave you bigger borders or slight offcenter for some things.

Maybe the Vintage Edition of CPU-Z would detect it properly? I keep both the Vintage Edition and a modern version around since they seem to detect things slightly differently.

Nice upgrade btw!

Just tried it, still reports Unknown CPU Type.

Found out a USB Toshiba floppy drive. I'm happy 😀

After bringing home the 5160, I was able to find out a few things about it.

On the nice side, it has a full 640k installed between the 256k Motherboard and a RAM card. I was also able to get the MFM hard drive to come back to life after tapping on it. On the bad side, it can't boot Cassette BASIC due to an issue with one of the ROMs, and the HDD is a rather intensely loud. Like, it sounds like a jet engine at times. I was able to put my recently acquired EGA card in there, so I have a mostly working system. At least for the moment. I might be able to create a bootable floppy before the HDD dies again, and from there I might be able to get an XTIDE going as well.

trying to install windows 2000 on the dual pentium pro meeting with a lot of problem related to the file corruption and bluescreen.
it seems like the ram i'm using is not happy with 60ns setting.

set ram speed to 70ns and try again right now

Today I went back to my Nexgen Nx586 system to install Windows 98 SE on it. It works fine,

System is:
- NexGen Nx586-P90 on PCI mainboard
- 64MB EDO RAM
- ATI Mach64 VT2
- An ISA Acer M5105-based I/O card, better compatibility for serial mice than the controller on the mainboard
- IDE to SATA (SSD) adapter
- Not on the picture, but an ESS Solo-1

The lackluster original CPU heatsink/fan has also been replaced by a modified socket 7 one, much better in any regard. The RTC module was of course dead, so now it has a disconnectable battery.

Used this to power a cpu (Pentium with Vcore and Vi/o @ 3.3V) while waiting for the replacement (LM1084).
Edit: I tested with Vcore= 3.3V; 3.45V; 3.55V; 3.6V : no POST

Didn't post, Vcc is correct but maybe amperage at 2A isn't enough.

Today, I managed to revive my old system gifted by my father.
AMD K6-II 3DNow 500 MHz with Zida T530B-S Super Socket Motherboard.
I need to replace the BIOS IC and the Clock IC.

One small issue still exists.

In this setup, 256 MB x3 RAMs are showing as 128 MB x3 RAMs!
The eBay seller already said - "It displays 256MB on motherboards above version 815, and 128MB on motherboards below version 815. It requires updating the motherboard BIOS to display 256MB"

Is there anything to do?

Stress testing my yesterday built Tualatin Slotcket mod.

I had Celeron 500 original cooler laying around. However its fan produces rather annoying slight whine. So replaced it with modern fan. While it's not CPU cooler with it's 2100RMP (instead if intel 3000) it seems to be providing enough airflow to keep my temps in 45 - 55C bracket. Not pretty with self tapping screws but I'm Ok with function first looks later approach.

Today I tried to recover three MB, an ASUS P2B-F, a Compaq Camaro (Mitac), and an ASUS K8N-E Deluxe, with the first I have to do a test, to rewrite the BIOS via floppy (recovery BIOS), but if not the only solution is to change the BIOS chip with another (probably new one), if that doesn't work, I don't know what else to check or try.
For the second one, the Mitac I have to try some tracks on the back, maybe one or more are interrupted or damaged, if I find one interrupted, it could be fixed and the card maybe works again.
To finish the K8N-E Deluxe, I tried to install Windows on a 40 GB WD SATA disk, via CD reader, no version installs, tried from 98 to XP and even 7, when writing to the disk the installation stops block.
The only thing 😨 I can do is change the location of the SATA cable, but I don't think it will make any difference.

1st: I had that with a dead bios chip; but also with a dead RTC, and a dead crystal. If it helps at all.
3rd: don't you need to slipstream SATA drivers into the installation ISO image? IFRC sometimes loading from floppy fails. IDE works?

Edit: isn't 2E 2F video card related?

codes also point to

2E Detect and initialise hard drive
2F Detect and initialise math coprocessor

Bios chip rotten too?
