Another old timer saved from the bad fire - finally got round to recapping my old Abit BE6 (Caps Replacements). Only replaced the main Tayeh caps FTM with Panasonic FR series, but did get some others in just in case the rest start to show. Board now working & stable to 1GHz 😀

Nice!

I also have a BE6, it was my first slot 1 board, so it is a bit special for me. Unfortunately it is very unstable! Do you think a full recap would help?

Thanks

Snagged a V00D00 4 4500 off eBay for the price of a VooDoo 3 3000, got it sitting here waiting for its new home a P III 1.4s Tualatin system I also snagged. Tho I'm debating if a TnT2 Ultra with SLI Voodoo 2 would be a better fit for a P III, but Im excited to get that V4 up and running.

I think I got lucky with the P III, its a SiS635t board with DDR so it should be quite a fast little retro box when finished 😁

I had a BE6-II, it was the most unstable POS Slot-1 board I ever used to be honest. When I got it all caps were shot, and even after a recap (to be fair I did use cheapo caps for the job..) it was flaky as hell. It frustrated me so much that I simply junked it.

Cleared out some of the junk from my Versa parts stash after attempted fixes.

- Ultralite Motherboard (too much leaky cap and seafood damage)
- screen parts (frames, glass, etc)
- a few other bits

Ordered another "V/50" (actually a 40EC) for parts. If I cant fix the real V/50 ill build a 2nd 40EC so me and the wife are on the same hardware when LAN gaming (40EC, 20MB RAM, Cisco 802.11b wifi, dos 7, wfw311). Ill put the marble screen on this one and give it to her (nicer) and Ill put the other on mine, then sell the V50 for parts (lots of good parts). Then its DOOM/Duke3d/Diablo time.

Fabricated this 60mm Noctua fan with 60-50mm adaptor on a Pentium 60.

I'd just figure out a socket 4 mount for an AX7 if I figured out a P5 clockchip mod to 100Mhz 🤣

What are you planning on doing to that poor p60?

Today I had my first "I regret this hobby" day. It started with attempting the circumvent the 504MB limit imposed by my BIOS by using EZ-DRIVE. Sure, everything worked up until the program decided that it should just boot to the HDD despite being told to boot to the Floppy drive, so I couldn't install DOS 6.22. After that, I went and picked up a completely different brand of mouse, and again managed to somehow get one that can be detected by CTmouse and windows, but can't move. At all. Even when directly rolling the rollers, there's zero movement. I am at a total loss as to how I can fix the issue, as both my VLB and ISA IO cards have the exact same problem with both mice. I also can't google the issue, as I only get completely unrelated questions.

Hmm, is that serial or PS/2? check the voltages on the serial port / isa pins. I seem to recall on this forum that people have had similar problems and it turned out to be corrosion that had damaged the -12v line which disrupted serial comms.
If it's getting as far as detecting, the pinout should all be good at least.

Yeah, at this point I think it’s just the motherboard. The mice work on other computers without issue. The computer was also having trouble detecting the IDE CD drive that had zero issues using the CD driver from windows 95, so I said screw it. The system is once again a pentium 100 on a case that’s Badges Pentium 75

Is this a propitiatory OEM motherboard? Iv had more issues with those then iv had anywhere else.

Nothing special, just running it at 66 MHz, because why not. And I like Noctua fans. 😉

It's certainly possible - the instability could easily be a sign of failing / failed caps. I only changed the 6 main Tayeh 1500uF as they were visibly failed (blown + either leaking or popped base plug) and the board would no longer even POST, but many caps regularly fail with no visible sign at all.

BE-II was more of an attempt by Abit to produce a performance / OC BX board than the basic BE6 so maybe that hand a hand in it (never had a BE-II but the similar MSI MS-6163Pro v2 is still one of my best BX boards)

It’s a GA-486VT with an absolutely basic BIOS from 1993.

I've been getting into contributions to vintage tech wikis lately. Started adding to preterhuman, thinking about adding to the Vogons wiki. Mostly hardware info.

Shot a very candid video on the Crystal CS-4231-KQ last night (NEC Versa M/75). I think my next sort of "when I can" project will be figuring out ways to get that crazy monster working in DOS. Showed off some games that work, some that should but don't (7th Guest and AD Cop puking onto the DOS prompt from setup) and explaining what I know. Seems theres not enough WSS codec stuff out there. Not sure if other laptops have the same settings but maybe it'll help someone with an M/75 at least.

Today I got everything back up and running with my P5 system, and I am wondering if I really even need L2 cache on a completely DOS Pentium system.

That's heresy!

*EVERY* system needs to be the absolute cutting edge it possible can be! It has to have the FASTEST P5 processor, all the memory banks need to be filled with as much ram as humanly possible! Overclock it! replace the processor with an Overdrive (tm) and overclock THAT!

If only I could afford to actually do that with some of my systems, like the TI-99/4A and VIC-20. Especially the TI. Those expansion boxes are so expensive.

I use to have a TI for a little bit before i realized I didn't have much money to dedicate to another type of retro computer. Its a weird little machine but fun for sure. You really need the ram expansion and atari joystick adapter if you want the best out of it though. Last i remember there was a community made PI based replacement for the peripheral box. But i might be wrong.

Speaking of weird things. I do have a PC9821 i got stuck with. Not the biggest Touhou fan on earth, so it just kinda ....sits in the cupboard and judges me....

Cool talking piece though! Love Japanese oddities.

Awesome. The TI I got was in box, “non working” and even had an Atari adapter. Of course, the only real problem was keeping it from booting was the fuse glued to the end of the transformer. Problem for me is, though, that I have the absolute worst keyboard membrane ever produced in there, making it hard to even use the system.

Had a wild hair tonight when I woke up to grab some water....ive been on a roll with card services for awhile and learning PCMCIA stuff. What I thought was a Panasonic KXL-D20 comes up as a KXL-C101. Got the bare driver going in DOS and the Win95 driver working. Port 330 OPL3 FM is working and so is SB compatible audio on port 240h...just cant hear them....no breakout box.

Looks like next will be setting up some kind of probing setup to listen to I/O for the audio signals off each pin. Once pins are identified, it appears pin 62 (SPKR) on the card is unused. Maybe Ill patch into that. That should send audio out thru the internal speaker. Then Ill have OPL, Soundblaster, and WSS all in one laptop...still some major R&D is needed first...may ho extetnal flat speaker instead. All depends how the 62/spkr line works.
