I will dig thru my boxes but doubt have a CJ13 or CJ17, have a CC-93-9F sitting here but the pinout looks different on the board connector.

Finished off the RiscPC replacement cmos battery project. Nipped the old battery off leaving about 3mm of the pos/neg posts sticking up from the mobo. Added some solder to them then tinned two pieces of 32 thou lockwire and soldered that to one positive and the negative posts. Bent the positive …

LOL love the topic you chose: "Cache woes. Is it Faulty or is it the Motherboard being spastic?" Are all the ram SIMMS the exact same ? If not could explain the "RAM at megabyte #3 is REALLY slow". Also try cleaning the simm sockets and simm edge contacts with ISO Alc. You should also try the cache …
Re: Need help identifying 386/40 motherboard
Posted on 2020-11-26, 02:32
Possibly Biostar, judging by the logos on the BIOS and KBC stickers. Agree ! The AMI BIOS id is for Biostar and the board logo's/locations also suggest Biostar. The closest match I get is a MB-1333/40 AEQ-K/AEG-K which is an American Megatrends 386 motherboard. Any help would be appreciated. the MB …

And does it detect your harddisk? Good question. I was not able to see that part, think because the System BIOS cleares the screen to show the config table too fast. Maybe I should try to switch off the HDD detection in the BIOS and see if it boots anyway. There maybe a problem with some NICs not …
Re: hdd replacment - sd card, cf card or scsi

A retro PC without spinning rust is an abomination unto the machine god. Keep your Seagate, keep it hunnid I'm switching to SSD and CF for all my retro systems, and SSD only for later systems. I am primarily a collector of graphics cards and CPUs, as well as a range of motherboards to cover all x86 …

Yes a good 486 without a true mechanical HD is like throwing a new crate motor in a 1970 Chevelle. Some things are better with closer to original equipment than some new tech stuff. I will never replace the mechanical HD or floppies in my Laser Turbo XT/3 with SD card HD/Gotek floppy but that is …

Re: Do I really need a floppy drive?
Posted on 2020-11-23, 06:02
Depends on what you are thinking of putting it in. If an XT, 286, 386 or early 486 then yes you will most likely need one. A Pentium or P2 you could go Gotek or floppy even if you think you can get by with just a CDROM. Thumb drives just do not work well in most anything below a P3 from my …
Re: Any Tips for installing a replacement Creative Sound card?
Posted on 2020-11-23, 05:49
Never had a problem with Win9x and Soundblaster drivers. With XP and above there is a file usually called CTZAPXX.exe that will be on the original CD or in your Windows folder somewhere, if you run that it usually removes all the SB drivers. When I moved from a cheap PCI-128 to a SB-Live under XP …

Yeah somewhere is my stack-o-crap have a few ISA jumper set old NIC's, think the BIOS might work in one of those but probably not in a software programmed one. I will find a flash chip and burn the rom for my DTC1181 some time soon

Thank you ! added: the ROM file looks good. Contains DTC LBA BIOS EIDE22A 04/02/98, and DTC YEAR 2000 (Y2K) Management BIOS Y2K13A 05/17/99. The PAL may be tricky to dupe but the 27C256-15 EPROM and 74LS245 are common, might be possible to build one by some reverse engineering. Am still trying to …

I got this kinda cool card, I put it in my 486 and it instantly worked. It is like XTIDE except it's OG XTIDE from the 90s before XTIDE existed. Also it fixed y2k bug. It detected my 32gb CF and let me format 32gb. no compatibility issues with my VLB Adaptec IDE controller. It also cost me way less …

Would anyone happen to know any socket 939 motherboard that would support dual floppy drives? I have a good socket 939 build and I could just switch the motherboard if I found such. Ha No ! Have one and has no floppy support at all. Not even a floppy header for one drive but guess that depends on …

Very odd that even going back thru Asus.com on Archive.org does not explain jumpers for using a standard 5v DX or DX2 very well except in table form. Did go thru a bunch of web pages/archives and Am guessing that when set as a Intel 80486SX, 80486DX, 80486DX2 or 80487SX that it bypasses the VRM and …

This ultra-cute 386SX system, with cute 9" monitor and some additional stuff. Needs some repairs as the pins in the PSU socket are broken. Perhaps needs new PSU too. Shouldn't be too much of a problem. I bought it mostly for the ST351A/X XTA compatible HDD which seem to be hard to find nowadays. …

One last question: Can Slot 1 motherboards boot up with an ISA-type video card installed? Or do they only accept PCI/AGP? Yes. I generally go with the lowest form of slot for video if testing a board. Have yet to see a Slot 1 not boot up with a good ISA video card (have never seen a Slot 1 with out …

This is interesting, particularly for those boards that do not have any of those socket tabs at all (early s3 CPU sockets). I'm not sure if the board pictured here is the board you are trying to create this fan mounting printed assembly thingy for, but even with just the 2 tabs (1 each side) and …
