I took the package with all PLCC adapters. It works great. Erasing/blanking/flashing is unusually fast comparing to regular motherboard flash from floppy 😀.
Unfortunately, it's not supported via "minipro" on Linux., unlike older TL866A, CS or II Pro.
TL866II Pro is the only one supported by both: latest XGecu software and minipro.

OK, minipro you say.. And here I was using Xgpro under WINE the whole time, I'm an idiot 🤦

Eh, didn't test Wine setup 😀.

Cyrix 6x86 150+ @120MHz. This is the first working Cyrix processor I've purchased.

I have a question. NSSI reports the name as random ASCI characters, is this normal?

Woow! That was the cpu in the first system I've built! So it was my first ever cpu 😀

Tried to overclock my 6MHz AT to 10MHz. It was already at 8MHz, and I had tried 10MHz once before with the result being a system that booted but froze after a minute. But now I have a few 68-pin PLCC sockets and I heard about putting a PLCC 286 into a socket and plugging that into a PGA 286 socket. I thought I had a 10MHz PLCC 286 in a drawer somewhere. It turned out to be an 8MHz part, but that is still likely to do better than a 6MHz one. So I put it in.
It boots at 10MHz, but with only 512KB of RAM. The memory on the Basic Time AT 4x4 Plus expansion card is no longer recognized. Some of the DRAM chips were 150ns, and I found 120ns ones to replace them with but it still wasn't enough. The Checkit 3.0 memory test showed no problems in the base 512KB, but if I keyed in the address ranges for the expansion memory (512KB to 640KB and 1.0MB to 1.875MB) it came up with a lot of errors. Guess I'll have to stick with 8MHz for now.

I'm playing with the VS440FX system, trying to install windows 98 and get the dvd-ram/pd drive to work with windows 98, and it is not the best experience in the world.
The panasonic driver work, but it won't play nice with external usb device, it will hang the system when I open the explorer until the driver was removed.
Nero inCD work fine, but sometime the system lock up for no reason.

and dvd-ram write speed is super duper slow.....
no wonder nobody want to use dvd-ram at all.

Finished Wing Commander: Privateer - Righteous Fire on my 486. Only played the main game as a kid.

Probed the faulty Roland SCC-1 with my oscilloscope today.

I confirmed the DAC appears to be getting a clock and digital input signals, but generating no output.

I'm going to do some further testing on voltages. Unless anything else jumps out, I may just replace the DAC and see if that fixes this card.

Posting about this now because it took me a week to get things going mostly right. I even replaced terrible old fans in the case and power supply with Noctua ones.

Yeah, I've been working inside my new-to-me Power Computing mac clone. One of those clones from the company that was getting new PowerPC processors before Apple, and got bought out at the end of the program as well. Still going to replace the not-working SCSI CD drive.

The thing is, it's also got something special inside it.

I got incredibly lucky, and got a Newertech G3 inside it as well. Combine that with the 320MB of 168 Pin EDO inside, and I have a mostly good machine.

Made an some silly Win 3.1 modification by the motives of Motif Unix window manager 😀

- partial LFN support
- FAT32 defrag
- file managers
- program manager replacement
- shrink it and make more DOS 7.1 compatible

Try PC Tools 2.0 for Windows, which includes Central Point Desktop. It is by far my absolute favorite graphical shell for Windows 3.1. The only downside is that there is no LFN support.

Tnx! I know it from the mid of 90’s but it not my fovourite)))

Unlocked 1024x768 in GLQuake. Now my ultimate Win98 build is finally complete with a PIII-S, FX 5200 Ultra and the Voodoo2 SLI.

Yesterday I broke my Nokia 445ZA out of the limits of its EDID EEPROM, by making an utility to produce a new one that exposes all it can do not just "1600x1200@85Hz". I will do this with all my VGA devices eventually.
I did a mod to move its EDID EEPROM to the neckboard for easy access, in case I needed some tweaks, since the original location is on the mainboard and in front where it is absolutely inaccessible and everything must be dismantled... and it was a good call as I had to change EDID version from 1.4 to 1.3 or WinME wasn't gonna play along and not recognize the monitor. This is why newer monitors will just be "default monitor" with limited capability since they advertise EDID 1.4.
I also repurposed the useless Serial Number Descriptor field as another Established Timings one to get bunch more supported resolutions+refresh rates instead of needing dedicated timing entries., 9x won't respect it but newer OSes will so it makes sense to do it that way too. In any case I no longer have to jump through hoops to get more tha 1600x1200 on this monitor or higher refresh rates ~
I plan to develop the EDID builder a bit more, give it some user interface and release it so people can try to break their monitors out the limits of EDID too.

I attached comparison of old and new EDID content, as presented by my EDID parser that got written before the builder.

very nice!!!!
does the new higher resolution stress the monitor components more?

Stress is function of operating freq, for example 1920 x 1440 @ 60Hz is 90kHz and 2048 x 1536 @ 60Hz is 95.3kHz which both are less than 109kHz of 1600 x 1200 @ 85Hz which the monitor advertised as its preferred mode.

Why use a 5200 Ultra, out of curiosity. A GeForce 4 Ti or a 5600 (non-ultra) I think would have been a better choice?

My personal preference is actually the GeForce 3, when I want to retain some shader support but don't care about or performance is bottlenecked by the CPU anyways.

For one good reason, I already had the FX 5200 🤣 I actually have the GF 4 Ti 4600 in the wishlist but since I don't need it urgently I'm waiting some listing at good price (like mostly of what I bought until now, that Voodoo2 was ~30€ + local shipping).

I don't think 5200 are actually that terrible in dx7 and dx8, kinda lower half GF3 levels, it's dx9 where it is dire. For the $20 they are worth, they are better value for money than other GF3 or GF2 options.

Given that I've had 4400s and 4600s die running stock speeds from BGA/solder issues on the RAM and two 4200s that do fine, one of which clocks high enough to give ~20k 3DM2k1 I would only attempt to acquire additional 4200s for additional GF4 requiring systems myself. If you want to hang it on the wall and look at it, get a fancy 4600 with original cooler and styling, if you want to use it on the regular, get a 4200 and upgrade cooling.

soldered new reset button on megadrive 2 now i can use saves on mega everdrive x3. success. followed this guide: https://youtu.be/6klndBZFU7Q?si=kP8HxS-LMTYh-f9b
desoldered one capacitor (JPCON 10V 1500uF) from MS-5191 which was bulging. motherboard works but crashes when changing audio properties, this one cap was suspect because of bulge. Still waiting for 10v 1500uF panasonic to come in the post. The motherboard is littered with tayeh capacitors which are shi*e. This was my orignial motherboard for my time computer with onbiard ati rage 128vr. it even boots on post screen with 'time computer systems' in the top part of the post screen.
ordered flux and wick (never used before), decapping wasa pain in the ass, the holes wouldnt clear. had to change tip to fine tip which could poke through multilayerd motherboard.
