I speak for the Swedish. Ask me anything. I will answer truly. Fascinated by mooses. Do you see them often? I hear they're a danger to drivers. Moose? Once I drove through south Sweden a moose walked out of the wood onto the road. It moved slowely across it, but it did not care about traffic at all …
Re: Mysterious earlier 386 motherboard VLSI

shit, i was looking for over an hour. and its listed as an intel chipset... still, 12 ram slots had me confused. The TOPCAT chipsets were developed by VLSI and supported 4 memory banks. Intel had licensed them and enumerated them with an own number. VLSI 82C320 = Intel 82340SX VLSI 82C330= Intel …

That is EDO DRAM. Do not mix them with FPM DRAM. Perhaps you continue with a FPM DRAM module first. EDOs in 486 were quite uncommon. Your cache chips are 64kx8. I cannot read your TAG ram, but I think it is a 32kx8.

Just be sure you won't connect Ground with Signal. It is unlikely you will damage the devices, but you'd better try to beep the Ground with a multimeter first.
Re: Covington 266 or 300
Posted on 2024-02-10, 10:34
Nah, the Covington is the Klamath without L2. There is absolutely no reason to have a Covington in use, except if you want to overclock a really bad CPU. On stock clock you'd get same results with Klamath or Deschutes @ 66 MHz and disabled L2-Cache. Due to the lack of L2 cache a Covington accepts …

2. I cannot confirm the scsi remark. First the bus master feature is known to not really do on 386. I benched a lot and posted it here somewhere months ago. Result: the 160gb Seagate will do it much better and more silent than anything via scsi. Maybe also because of 8mb cache. I benched program …

The DX2 has 5 Volt, the DX4 has 3.3 Volt. Are you sure your system supports 3.3 Volt processors? I am not sure, no. The bios detects it. I won't rely on that. It's you who perhaps has a toasted DX4 then. If I was you I'd either look for a power transistor like a 1085 or 1086 or a multimeter.

Re: What vintage CPU socket saw the biggest increase in CPU horsepower from release to retirement?
Posted on 2024-02-07, 03:45
I think socket 5 is probably the winner. You could get a brand new socket 5 board with a Pentium at 66mhz in 1994 and that was top of the line. Later you could buy a 3.3v Pentium MMX @ 200mhz as a drop in replacement - more than tripling the clock speed and giving you MMX. Socket 5 and 66 MHz …
