That's another problem too I suppose. I'll search for it. EDIT: found them a generic one. I'll try it soon. I've at least four different NE2000 similar cards, I'll take a photo to ask you which might be the best for such old machine (considering also I'd like to make it works in Win 3.1).

Understood. So I may use the NE2000 card into the 8bit bus and cover the 16bit part with eletric isolation tape and try to see if it works. I would have even used a 8bit sound card to free up a 16 bit connector but their prices seems a bit too high. Or maybe are there any combo cards like ethernet …

I don't own many AT cases so if I've to build one old machine like my latest 386DX one and I found a very similar case like I had in my first x86 pc (classic slim one with riser card) I like to keep at least the computer (not the monitor) enough period correct or at least the fastest/modern one …

Many ISA Ethernet NICs, including those based on the Realtek RTL8019 chip, can run in an 8-bit ISA slot . IMHO, parallel port Ethernet NICs are more trouble than they are worth and should be considered in a last case scenario only . But are they intended to work that way as retrocompatibility or it …

Hi, I've built this 386 machine which mainboard had enough 16 bit ISA connectors but I wanted a slim case so I had to use a riser card that have three 16bit bus and three 8 bit bus. The computer works, I'm still adjusting the components choice but anyway I wanted to have a ethernet capability into …

I just bought a flasher and a few blank EPROM chips expecting to need to put an LBA BIOS on a 486 motherboard I just bought, only for it to arrive and already have that updated BIOS on it. OP, is there a particular 64kilobyte image you're looking for? Maybe you can give me a use for it. …

I've seen that these UV eprom are sold on ebay already erased but the flasher may be expensive..

I've the PCI post card unfortunately when I bought it I didn't think to the …

Afaik there is no motherboard that can program UV EPROM on board, so you'll need an external programmer. But I think the problem is not with the EPROM, but most likely jumpers issue. I was thinking it too but I've seen an ebay auction of the same mainboard sold with a Dx2-66 and I checked in that …

About cleaning those cases, beside the chemical classic UV treatment, are there any fast and easier things to make them just a bit brighter/cleaned, I don't say like new but at least removing the "darker" shades of white/yellow. In past I had good results with the usual oxigened water and sunlight …

playing mp3 on 386 is only possible by using decoder chip on lpt port. MAS3507 for example. https://www.heise.de/ct/artikel/Mucken-statt-drucken-287008.html Sorry German :-) Interesting, it'd have been nice to see it into a specific ISA board instead of the parallel port.

Ah, sorry that this didn't work.. 😅 If you like, you can try MOD4WIN also. It's a MOD player only, but has FPU support for its IDO filter. When enabled, it will use the x87 to provide better interpolation and filtering (to get rid of harmonics). Definitely worth a try, I think. On DOS, Impulse …

I don't know if even back then there were different core stepping that had different realistic working temperature/TDP like happened on some Pentium4 where the same cpu could have had a 10-20W lower TDP depending if you're lucky to have a specific core stepping, but if I watch at the Intel 486 …
