Re: New 486 Build

I am testing with an ATX PSU + adapter, works fine so I don't think that's the problem. However, by looking at your jumper settings I noticed the following differences with mine: - JP23: you have 3-4, 5-6, 7-8, according to the DX/DX2 section on the manual it should be only 5-6, 7-8 - JP24: looks …

Yes, with the speaker connected you should be able to hear the error codes (unless the board is totally dead). I assume most ISA/VLB cards should work well with the LCD monitor, at least for boot screens and DOS. I never had any problems with getting my old cards to work with LCD screens. What …

Re: New 486 Build

Anybody know why the speaker has 5 pins allocated on the pin out? I am trying to use an ATX case and my connector has 4 pins. Just got my board a couple of hours ago and noticed the same thing when I was setting it up for testing. I think it's a mistake in the jumper diagram, you can use the last …

Re: New 486 Build

Based on the white mark in the top right of your picture (which should be pin 1), the "20" on the lower left and trying to match the diagram with the text on the board, this would be the pinout for the front panel on the picture you posted: 10 09 08 07 06 05 04 03 02 01 20 19 18 17 16 15 14 13 12 11 …

Re: New 486 Build

I also have a converter for the PSU but I think it is designed to let you use a modern PSU with an AT case and motherboard. I want to use it to let me use the old motherboard with a modern PSU and ATX case. There are 2 wires coming from it that I assume would be used to connect to the old power …

Re: What is your age?

34 here. I'm a software engineer, up until I was 30 I was almost completely dedicated to my work, but lately I've become pretty disappointed with the IT industry (all people seem to care about nowadays is social networks, stupid/useless mobile apps and hardware that cannot be disassembled :blah: ). …

Re: New 486 Build

Yes that board. I think it has the cache not sure how much. I have attached a picture of the board. I will be switching that CPU, I have several options for that. I have an AMD DX4-100. Will that work on that board? If I have the cache would 32MB be the best option? According to motherboards. …

Re: New 486 Build

You have the Acer/AOpen Vi15g right? Each 72pin SIMM slot on that board is an entire bank, so it's not necessary to install SIMMs in pairs. Regarding the amount of memory, either 16 or 32 MB will be fine if you are running MS-DOS games and applications. Assuming you have 256KB of cache, 32MB should …
