fixed it, a jumper for monochrome was enabled, which is odd because at 256k and 512k it didn't do anything so i remain confused

So I have a paradise card with the 8900c chipset, it came with 256k, I added more ram to make it 1mb but at 1mb it only works in black and white, if I take it down to 512k it works fine again, I'm tempted to try 768k but haven't yet. Anyone have any ideas? This is in my 386sx

The old CPU marking is NG80386SX-16 (L1344284), however, the old CPU is not the problem, I can even overclock it to 20MHz. The thing is, that the "new" CPU is actually Am386SX/SXL-33 with markings NG80386SXL-33, NG80386SX-33 (C 224BA8E), however I can't get it booting with 33MHz and even 25MHz seem …

Just one question, and I'm not the only one: Why on earth would you cover up an actual usable port and state in the manual: break me if you want to use an external keyboard??? Just open it up in the first place. Saves a little material (and money over thousands of laptops) and don't let the …

It wouldn't make sense to change clock speed on the fly, the 486 doesn't support it, that's in the documentation.

For memory you need a ram card, I'd get a ram card combined with I/o though as the PC only has 5 slots.

I added active cooling to a 486 DX2/66 (heatsink and small fan), and I have a large one on a DX33. Those chips get quite warm, and while they can operate, I think for longevity it is best not to allow them to heat up significantly, to avoid stress of thermal expansion. There is no harm to adding a …

P19 doesn't support it out of the box, but p15 does? Seems counter intuitive. Yes... that sounds strange, but that's how it is. With a newer BIOS, the PC will boot up, but you will get an error message saying that the processor isn't supported. The same happens with some 440BX mainboards made by …

I use the similar method a laptop uses for mine, I take 2 cr2032, a speaker wire stripped and put red to + and black to - electrical tape it then heat shrink and then on my 386 I let it just sit on the board since it's a desktop not a tower. Works well, has the convince of cr2032 but connected to …

I noticed similar with my St dx2-80 aka cyrix, in Doom and 3d bench it scores slightly slower than the dx2-66 from Intel I had. I'm keeping it though because everyone does Intel or maybe and, but who does an ST 486.
