The processors start running in the …

Looking at their website, they don't even have cases in stock - and they want to sell those and the keyboards separately. It's a microATX motherboard so it'll fit any standard microATX case. Something I gotta wonder though - might it have been possible to reverse-engineer the VIC-II chip and make …

No, there is a list of games that support dual OPL2 on PAS only or SB Pro 1.0 only. This was discussed previously and it's due to the …

From the video, it sounds like it's mainly the PSU fan. A newer PSU will be quieter as it'll use a 120mm fan instead of 80mm (lower revs for the same volume of air moved), have a temperature controlled fan, and be more efficient (80+% compared to 70% or less for PSUs from that period; that's from 20 …

My understanding is that Trim support is more of a device /driver/ file system issue than a legacy vs AHCI mode issue. While trim and AHCI came out at about the same time, they don’t necessarily depend on each other. Trim is an ATA-8 / ACS2 command. Seems to me that it is fairly likely that what …

JemmEx is open-source, which means anyone can modify it, subject to the terms of its licence. It's a good thing that it is otherwise the only option SBEMU has for port-trapping for real-mode software is the closed-source QEMM as EMM386 cannot trap I/O ports below 100h, which means no ISA DMA and …

The SM2236 product brief does not mention support for TRIM. Even SATA SSDs need the SATA controller in AHCI mode to …

The common answer to your recent questions is StarTech. They sell a number of different internal power cables , have look through to see which ones you need. E.g. there are also SATA to 2 Molex, SATA to Molex and floppy power, etc. At least it'll give you some search terms when looking for them …

By special characters do you mean non-ASCII characters like letters with accents and cedillas (e.g. ê, ç)? Then it is likely a character encoding issue. Linux usually assumes UTF-8 encoding whereas DOS uses code pages which specify a different characters for the 128-255 range, usually 437 for US …
