I have the exact same model of case, I bought mine new 1997 if I remember right. Its a great case as it supports both AT and ATX form factors which is kind of rare. I would not do any modding to the case it self, if you want to add switches in the front, mod a 5,25" fan controller.

Skyscraper Would be nice if you tried Speed Test in DOSBox on default BIOS settings. There is no clear data still about DOSBox emulation on 486 CPUs. This system only has DOS 6.22 installed at the moment, sorry. If I load "BIOS deafults" and set all settings manually I get even more memory …

I could not find a general 486 Speedsys thread so Im posting some results here. Asus PVI-486SP3 with 256KB cache, an unknown AMD DX4-100 probably a NV8T and 2x8MB double-sided FPM. The CPU cache is jumpered as WT as I think the CPU dosnt support WB. I can not upgrade to a newer BIOS than 0205 …

Im messing with my Asus PVI-486SP3 rev 1.21, SIS chipset revision B4, BIOS 0205. I had almost forgot how fun it is to play with these boards. The board came with BIOS 0203 and an Intel DX2-66 mounted in the socket but with totally different jumper settings than it should have had... I tried to …

Nice! I updated your Socket-1366 system's score aswell as I missed your edit, now that system's performance is more in line with what it should be! 😀

Holy cow, that case is amazing Holy cow, that case is amazing I've never seen anything like it. I would love one of these to run my Socket 3 and Socket 7 in one case! LOVE THAT CASE! Someone tell CaseLabs to make an AT version of their $600+ cases! =) Its a pretty spectacular case :) I found it in …

The board running Nice case! What is the name/brand? I do not really know but here are 3 photos I took two years ago. The only thing missing in these pictures is the PSU as it was missing at the time, I have found it again though. The PSU has enough cables for 3 complete systems. big case 1.jpg big …

the Asus board will likely run an AMD 5k86-pr75. Did you mean 5x86? I was under impression that 5k86 is an older name for K5, a pure Socket 5 chip. I need a 5V 486 CPU for testing an old unidentified ISA only board, the Asus board will likely run an AMD 5k86-pr75. 5x86 is the 133mhz AMD 486 chip :) …

I got another 486 motherboard today. Its an Asus PVI-486SP3, it wasnt very cheap, ~60 Euro with shipping but it seems to be the going rate and the board has the B4 rev SIS chipset and is in perfect condition so Im happy. I also bought an Intel DX2-66 for 18 Euro shipped with the board. Intel 486 …

I replaced the bad NICD 3.6V rechargable battery with a NiMH 3.6V rechargable battery on my PC Chips M209 286 motherboard. Plan A was to use a battery pack with the external battery header, there is no polarity marked and my multimeter only measured +0.2V at most on the header pins, I guess there …

How do I identify an C series RTC? Does it have an marking C? The boards I want to replace had an ODIN RTC 887A Modding the old ODIN RTC is easy if you want to save a little money. I used sandpaper to wet grind down to the battery, it took perhaps 10-15 minuts. This way the mod will not look as …

Yet another flawless victory! I could not get more than 560KB conventional memory free with the PC Chips M209 80286 motherboard equipped with 1MB DIP memory as the board dosnt support using the upper 384KB as XMS memory. Someone said it was a pain in the rear to fit SIPP modules in this kind of SIPP …

That's a LUCKY STAR motherboard, not MSI. I have the revision "d" version, it is a very good performer Like mine it probably has an Award bios with the Y2K bug, just set the year to 1998 and the days and month will be correct. No bios flash possible as it probably has a non flashable eprom like …

I will be testing them using the same unscientific method I used for the smaller drives only with DOS 7, FAT32 and a motherboard with better support for disks larger than 2.1GB. 1. See if the disk spins up without making nasty sounds 2. See if the system can find the drive. 3. Remove all partitions …
