Finished up the NEC Versa laptops last night, now all are working. The only future plans are power supplies, hard drives, bags, and other boring stuff. I MAY do a project where I modify the battery to utilize USB LiIon batteries like those you plug into your phone - the charge output looks to be, per digital multimeter, almost 100% dead on. Definatley something for me to look at.

Did electronics wizardry to the M/75 and upgraded the screen from a 640x480 to 800x600. The input board in the screen hinge cover had an unpopulated SMD resistor place above one of the IC's that is present in my Versa P/75, so I copied that with regular resistors - it's a 1.5K Ohm - and BINGO, the N.O.S. 800x600 panel came right up nice and bright. The backlight was a little "yellow" so I put in the backlight from the dead NL6448AC30-09 and it's really nice now. I still kept the other CCFL backlights from my other dead/damaged screens so if I need one, I've got plenty of spares on hand, at least 4.

The 40EC was put back together with the 16MB card I bought 3 years ago and it's original NL6448AC30-06 screen. Booted right up and it's happy now. So now all four work, have working screens, setup HDD, and I have one working battery ATM....maybe two since I plan to try the USB pack experiment on the 40EC (that one has always been my guinea pig).

That is amazing.

Which sound card does the M/75 have? I'm eyeing on one on eBay (cannot post the link since it's an active auction) and it's in great shape for its age.

The NEC Versa M/75 has a Crystal CS-4231-KQ WSS Compatible chipset and no OPL/MIDI. It can emulate digital audio SoundBlaster in games compatible with WSS or via Windows using SB Emulation Layer/Windows Sound System SB Emulation.

Man, I was hoping for an ES688F and a YMF-262M. On the plus side, I have an EXP CD-ROM + SoundNote that I can install on the system.

Haven't posted anything in awhile, did some minor stuff today for a few different computers.

First up, I had the itch to build a late 2004 system floating around in the back of my mind, with early Socket 775 and first gen PCIe.

While doing some extensive physical media backups (scans and CD/Floppy dumps) in the last couple of weeks, I re-discovered the advertisement inserts inside the original World of Warcraft Collector's Edition box, singing the virtues of the well-loved Pentium 4, the cherished Intel 925X Chipset platform, and absolutely adored Nvidia 6000 Series cards. So I thought "hey, why not just build a system using whatever these advertisements tell me to?"

Got my hands on some good parts for it - Asus P5AD2 Premium (as seen in the Maximum PC Dream PC 2004) complete with all accessories, a Pentium 4 640 that I permanently borrowed from some Dell office machine will eventually replaced with a P4 560 or 570 when I can get one at a good price, 2GB of 533MHz DDR2 that I had laying around, an Audigy2 ZS Platinum for sound, an Antec P160W for the chassis, two NOS 2008-dated 250GB SATA HDDs, and a Corsair RM550X for power. There's also a Thermaltake Pipe 101 CPU cooler that I'm not going to install until I get the right CPU.

For the graphics I wanted a 6800GT PCIe since 6800 Ultra is unrealistically priced and scarce. It turned out that the 6800 GT PCIe aren't easy or cheap to come by either, since people are asking 6800 AGP prices for the PCIe cards. I compromised and picked up a Quadro FX 3450 for next to nothing - they're cheaper than no-brand S3 ViRGE cards these days which I can't complain about. Building for a period that is not in fashion at all has its upsides after all!

It is equivalent to a 6800GS, and performs near identical to a 6800GT at stock. It overclocks like a beast too, but I'm only keeping minor overclocking on it. If I can get some more cheap ones I will push it a bit further. Seems like the perfect stop-gap card until I find the real deal at a price I'd be willing to pay.

However, the Quadro fan shroud was bothering me even though I couldn't see it. The mere presence of that ugly, plastic, cheap black corporate soul-sucking, fun destroying shroud was ruining my uber l33t 2004 gamer rig.

To remedy this I ordered some new old stock Nvidia Reference design 6800 fan & accompanying shrouds (feat. Nalu) to put onto the Quadro.

D7MHEFGl.jpgCRdwnKvl.jpg
i8FvOrxl.jpgTR99C2jl.jpg

I know it's still a Quadro as etched onto the chip, but just having "6 Series" on the shroud instead of the Quadro logo makes me feel better until I can get the real thing. With RivaTuner & some BIOS modding, the cosmetic appearance both physically and in-software is there.

I went ahead and set up XP Pro SP2 without issues, installed all the drivers and went back to the good ol' days of community modded ForceWare drivers. I figured it's right in the perfect hardware time period to play with them once again. After tossing up between DriverHeaven Zer0point, Omega and NGO, I settled on the DH drivers for now.

A few more important pieces of software later - SpeedFan, X-Setup, NVHardPage, some era appropriate games and other miscellaneous tweaks, the system is ready to go. There's no cable management done yet since I want to wait for everything to be finalised other than the GPU - so two more hard drives, a non-Noctua rear fan, the CPU and so forth before I go to the effort as it'd all have to be undone to add any of those after the fact.

Secondly, some minor work on the long-neglected ABIT TH7II-RAID.

While ordering the aforementioned 6 Series shroud & fan, I picked up some Socket 478 retention clips to mount my old Australian Made Silverprop socket 478 CPU water block to the board (I've been hunting this for about 10 years and finally got one about 6 months ago!), so I installed that today. Luckily it was spot on and it holds very securely! I still have to recap the board and do a whole lot of other stuff, but it's a very low priority project. Baby steps.

Finally, some blank EPROMs for XTIDE BIOS for my main project at the moment. Only verified they work and aren't fake. Was able to successfully blank check, write to one and read it back, so it's all good!

Picked a 27C128 series to use the larger version with menus and whatnot after padding.

I hate bent pins. This DX4ODP100 was utterly mashed up. Managed to get almost everything reasonably straight when this corner pin S17, ADS, broke 🙁

Might be able to sort of fix it, but at best this will now be a fragile CPU to gingerly lower into a socket once and keep it there :'(

The picture is a little blurry, but it looks like there's still quite a bit of metal there to solder in a new pin. Luckily, corner pins like that are the easiest to solder since you can hold your iron off to the sides without touching other pins.

Dual processor board for Proliant 1500,
Investigated the dipswitch and BF0 and BF1 and, sw 1 for BF0 and sw 2 for BF1, which can run either 100, 133, 166 and 200 using unlocked Pentium 200 processor.

Setting SW 1 or SW 2 "on" pulls low.

Cheers,

Gave my newly build Commodore64 SixtyClone-250466 "Black Bessy" a test for a couple of hours. Tested settings in the ARMSID, and chose filthers 3 notch down. After that I played some Batman the movie, Giana Sisters, Golden AXE, Super Cycle and Winther Games.

I also had to get rid of the RF Modulator replacement, and used an original NOS one that I initially bought for the project. I am blown away by how good the image quality is. This is like 1986 all over again, because the build is a clone of the 1986 model that Commodore produced. Next step is to solder in the cartridge port shield, install some casemod that I have in mind (internally non destructive to the case) and add a silent fan to give the VIC-II and the 5volt regulator some better cooling. I also have to source more aftermarket replacement parts, like S-Ram upgrade and some ESR protection to the CIA chips. I also had to use a CIA from an Amiga500, because one of the C64 version was completely dead, to the point were DeadTest gave no error, yet brought the entire system down in a seriously big way. Strange....

Oh well... My homebuild and completely new Commodore64 is a reality now. I am extremely pleased with it. And proud that I was able to actually build a functioning computer from scratch. All solderwork was done well and in one go. I think that it was done well, because I took my time to do it right. I did not make any solder bridges and electrical contact is perfect on all soldering.

Don't eat stuff off a 15 year old never cleaned cpu cooler.

Reconfigured the compaq deskpro 4/33i for 386DX 33 mode via dip switches and replaced 486 with 386DX and is running doom for testing. In 386 mode does use 395DX cache controller as zero wait state 16K.

Also moved a jumper to turn off the onboard audio chip.

Have to decide which sound card for it. DOS only, ESS1xxx or Aztech sound card which is good?

Yes, that's why I'm optimistic I can fix it. Ideally I'd use an interposer so I can keep the dodgy connection in the same socket all the time. Does however somewhat defeat the purpose of the ODP to use an interposer after all 😉

My floppy drive arrived, so it has been maintainance day for my 2005 time machine project, the floppy drive is installed and i finally managed to find a pinout for the USB ports of the case so i could finally hook them up to the motherboard. For those curious the USB 2.0 port header on your motherboard will have a gap in the left bottom, from that angle the top row is the 5V, the row above the gap is the ground. That should help you hook it up properly if you do not have it as a single connector in your case.

I have also been playing with TCP Optimizer a bit in XP, and now i can finally get maximum speeds on the rig! To do this i put it on 100mbps mode, and then clicked custom. There is a value that you see increase as you slide it, should be at the left top. I changed that to 7777777 (7 7's) and rebooted. Now i can finally enjoy my full 30mb/s (250mbit) downloads on the retro machine, and i am no longer capped to the default 3mb/s or as i previously had it tweaked 9mb/s.

I have been playing a lot with the modded drivers for XP that i could find as well, so i will share a few of my experiences on my 6800GT
- Latest Omega, Seems nice at first but avoid it. The moment you plug a VGA cable into it instead of a DVI cable it implodes.
- Latest NGO, seemed fine but i didn't notice anything to special.
- Zeropoint, Haven't tried it yet but its quite a bit older than the others so i also did not see much reason to try it.
- DNA-Force latest, seemed promising contains a fun tweak utility to. But turned out to have serious texture problems in some games like Wolvenstein.
- DNA-Force 3.8.163, this one gives me really good gaming performance especially since they let you pick what kind of performance mode you like. So definately a great gaming driver, its stable to, but i did notice that firefox doesn't use GPU acceleration on this one, making my browsing experience very choppy and slow. Not sure if thats a tweaked driver bug or the fact the driver is just to old for firefox to really use it. This also is debloated, so no NView or Background services.
- XTreme-G 191.07, this one is pretty basic to similar to NGO's driver. Just a period correct driver with some tweaked settings. Firefox is smooth here, games run great although not as great as the performance mode on the DNA-Force driver, great stability so far, and new enough to ship with cuda and physx in case you ever want to use it on a card that supports it. Because its based on 191.07 this driver is substantially newer than the other modded drivers i have found so far and i think this alone fixed my Firefox issue. Picky games like Wolvenstein with the texture bug, or Half-Life 2's Retail version which also had texture bugs on the latest nvidia driver run fine here. Newer games like Unreal Tournament 3 run great to! So all in all its a great mix of performance, stability and compatibility.

So my current winner is XTreme-G 191.07, but if anyone knows other tweaked drivers that are even better than the ones i listed i'd be happy to try them. I absolutely loved modded drivers especially since it was such a hot thing in this period. And my XP install mostly runs off modified drivers. I modified the VIA Chipset driver for compatibility with my T5710 in 98 despite being newer than the driver it supports and also to include the audio driver rather than having to download it seperately (Only if detected). Got the PAX-NewYear driver for the Audigy which gives you the Audigy 2 ZS / Audigy 4 software suite (Also works on the Soundblaster Live for those interested) and then the mentioned GPU driver.

2x WD SiliconDrive II 1GB RAID0 + 2x Kingston 16GB RAID0. Windows 2000 boots pretty fast, but not as fast like some post-modern SSD.
Maybe I'll get two 16GB CF cards more, and configure RAID5 so the i960 and RAM will get some work to do. 😉

a post modern SSD wouldn't be fast, it would spend all its time arguing in an unprovable and ever shifting way about relative power imbalances and relationships between parts of the stored data therefore accessing data, or 'socially conditioned data discourse' as it would have it, must not happen at any speed which disadvantages other data, or something like that!

I bought a spares and repair Dell XPS 1530 laptop without a HDD. It has a t8100 2.1GHz CPU, 3GB of RAM and an 8600GT video card. I was hoping the Spares and Repairs just related to it not coming with a HDD but it didn't power up at all when I got it.

I took it to bits right down to the chassis and couldn't see anything funky so put a new CMOS battery in (you need to remove EVERYTHING to get to it, unhelpfully) and still no joy. I treated it to new thermal paste whilst I was in there, and dug out a 120GB SSD for it.

I bought a new charger for it and now it boots up, yay!

I'm going to use it for a bit as an XP laptop and play some games and then drop Windows 7 on it to see if it is bearable as a "modern" laptop.

The P/75 has that exact setup I believe. It has OPL3 support that much I do know. Surprisingly loud for a single speaker output laptop from 1995.

Whoah, how well does that card work? Does that have OPL? I'm looking to slap some OPL compliant cards in my V/50 and 40EC, maybe even the M/75 if it has Adlib support. I've been hanging out in the PCMCIA Sound Card Megathread a lot since I got the 40EC in 2019. Theres a part of me though that's tempted to make my own PCMCIA SB16 compatible card though since I have skills to do that sort of stuff.
