I have this Toshibasatellite 220cds in my hands, but it doesn't show an image, nor does it rotate the HD, it just turns on the LEDs. My debug card connected via the serial port indicates that the last codes were 04, 05, but Toshiba used its own bios at that time (was it its own bios or just a …

In fact, there are a lot of complaints about the mouse on the 86box, they tried to improve it compared to the PCEm, but it ended up making it just as bad.

I currently have an ADW, and this ADZ appeared at a great price, but I don't want to buy more things to store them here. I read in some places people saying that ADZ supports higher temperatures because in fact the core was made to operate at 160mhz, but with the launch of the AMD K5, AMD feared …

I'm looking for a USB card to purchase, I tried via 6202, but it only works on some computers, and it definitely doesn't work on my Intel Advanced/AS AT which doesn't have 3v, or ACPI, installing the driver will crash the computer, or it will crash during boot. So I decided to look for NEC, I didn't …

I have this computer, the image produced by the video card has this strange horizontal effect (out of sync?), the attached image I created in photoshop to accurately illustrate the problem. I can also notice a "morié?" ghost in the image. Facts: - I'm using an LCD LED monitor in perfect condition, …

Both the PSP and PSVita ended up becoming very niche products, as smartphones evolved and became more powerful. People simply emulate these consoles on their smartphone. Personally, I love them both, and I intend to acquire them in the future for nostalgic reasons.

Just be cautious with Mach64, only the pre Rage models are capable of handling 3D, most of the Mach64 line (non GX) is 2D only (usually limited to 1 or 2mb of vram)

Any accelerated video card from 2MB to 4MB. This configuration was very common in 98, 99, and although there were cooler things at that time, I believe you are trying to recreate an average computer from that time. Yes, there were powerful cards up to 8MB, just like there are RTX4090 nowadays, but …

I followed the topic here because I have the same doubt as the title, but so far no one has talked about UniPCEm. I haven't used it yet, but I think it's somewhere between dosbox and pcm perhaps? UniPCEm continues to be developed? How fast is he? What requirements?

Oh, sorry, I forgot to provide some information: The fuse is perfect (maybe it's new), and when it's connected to the PC, when you try to turn it on, the speaker makes a noise, but it doesn't start if you want the fan itself. When removing it from the socket, I can hear that brief thin noise …

It does not have a traditional …

I have such a motherboard, but without video. It has been running P-MMX 233 for many years without an additional VRM. To set the multiplier to 3.5, a wire jumper is used on the processor pins. This board also has a working PS/2 port, you just need to solder the mouse header and FB8N1, FB8N2, FB8N3. …

Im skeptical about this being a footprint for a dual voltage regulator. Those need a way of being wired between CPU and power source, that means jumper links when one is not fitted. No jumper link means CPU is hard wired to 5V. btw where is the ram for mach64? does it come with a daughterboard out …
