Did you try all driver versions between 8.05 and 30.82?

ElectricMonk, you might find interest in these threads, The Ultimate 486 Benchmark Comparison Phil's Ultimate VGA Benchmark Database Project There is quite a bit of data out there which indicates the Intel DX4's having a clock-for-clock advantage over the AMD DX4/X5's.
Re: Anouther dual Tualatin machine.
Posted on 2014-07-09, 06:48
I have been running my dual Tualatin system at 1.5 GHz for approx. 2 months now. The system is on 24-7 and I have not had any problems arise that I am aware of. I think 1.53 or 1.54 GHz was the max that would run reliably at the stock CPU voltages, so I took the speed down to 1.50 GHz. I do not …

The performance effects of 10 ns vs. 15 ns cache on a 486 are inconsequential. Noticeable performance benefits are controlled by the cache timings set in CMOS. Vetz, did you use an SRAM tester? I ordered over some 150 units at one point and tested all before sending them to a few forum members. …

As I no longer have time to devote to this hobby, I'd probably let it all go, but only if it all could go at once for the original price paid. Free the mind, fill the pockets, save space.

If in an instant you could regain all the money you've spent on your retro gear since you started this hobby and forgo all the gear, would you?

Picked up a Cypress CY7C187-15PC 64k x 1 TAG chip to fill the U28 DIP-22 spot in my Asus 486SP3G board today. Hopefully this will mitigate the WB issues. Also.. finally ordered a bunch of the IS61C1024-10N chips from China. They should be here in a few weeks. How many did you order? Expect a 10% …

Between the Raritan, Vetra and KVM-based converters, I personally found the Raritan to perform the worst. I wonder if the types of PS/2 mice tested has something to do with it. My test mouse was a Logitech MouseMan (trackball). My screen resolution was 1280x1024 in Windows NT 4.0. I do recall …

It really boils down to if I beleive there is a greater risk of fire or burglary. I will have an absent minded relative staying at the house in my absence. She has been known to leave the patio door wide open at night and to also leave the stove on. As such, I predict the risk of burglary and fire …
Personal dilemma - going on holiday
Posted on 2014-06-26, 11:11
At some point this summer I'll be going on holiday. I have a rather large fire safe at home, which I was thinking about storing my more rare CPUs in. Here is the dilemma - do I store the CPUs in the safe to protect them from a fire, or leave them sitting in a box in the closet? If there is a fire, …

You could desolder that header from a dead motherboard. Even if you have a 4+ pin header, they are meant to snap to reduce in size.

MX8315 for generating the FSB. This chip will generate 20, 25, 33, 40, 50, 60, and 66 MHz FSBs from your 14.31818 MHz crystal. There are 3 inputs on the MX8315 which select the FSB. I suspect that if you solder in the missing jumper header, JP19, that you should have access to the full spectrum of …

If you don't mind your mouse skipping around a bit with some lag, go ahead with the vetra systems converter. Also keep in mind that they have 3 such converters. All convert PS/2 signals to RS-232 signals and each unit requires a very specific mouse driver that you will need to hunt down. The driver …
ATI Rage 128 VR does not cooperate with Cyrix 5x86 chips in NT4/W2K
Posted on 2014-06-25, 13:24
I have an IBM 5x86-133 system setup with a PCI ATI Rage 128 VR card. The display driver works fine in Win9x using the IBM 5x86-133. In WinNT 4.0 and W2K, I get BSOD upon reboot after installing the drivers. I tried every driver revision I could find. Normally, I would conclude that this graphic …

I only put the battery in. How much do you think these can go for? After shipping and such, a brand new RTC from Maxim is around $22 USD.

I have only seen it whereby you can use DB9 RS-232 and RS-485 serial devices on a USB port, not the other way around. If you have a link to someone who has made a converter that lets you use USB mice on a computer's RS-232 serial port, I would be interested.

I few minutes in google should provide plenty of answers. This topic has been beaten to death. 1) PCI PS/2 cards are really USB cards with a PS/2 converter on it. You need to install the USB drivers for this to work. It will not work out-of-the-box with DOS. You will need to figure out how to get …
