Here's the one I'm using with my 486. My first computer was a Compaq ProLinea 4/33 so I was trilled when my high school computer teacher gave this to me my senior year. I've never been able to find another one like it but I'm sure someone has one somewhere. If not I did scan mine in at high …

Finally found my scanner so I could scan in my MHz display configuration document. It's for either a T-583 or T-586 MHz speed display. Thought I'd share it here in case anyone needs to configure theirs. I scanned it at 300dpi so It's printable at Letter Size 8.5 x 11 in (215.9 x 279.4 mm), which is …

While going through some old photos I took as a young teenager, I came across 2 that showed my uncles computer at the time in 2005.

For the numbers display to work you need to provide +5V from the power supply. It's the last two pins in the center row of the display, labeled G (Ground) and 5V. Most AT power supplies came with a 2-pin +5V connector for this purpose, if yours does not have it you can build one, or use one of …

Hi, not sure. That i/o range seems to be used by serial devices sometimes, too. FreeBSD mentions them at ISA ports 100h and 108h, for example.. That would actually make some sense, being I have 2 ISA slots open one 8 bit and the other 16 bit. Question is why would Windows 95 even see the open slots …

I'm honestly curious what devices these could be on my 386 system. It runs fine in DOS and Windows 3.1/95 but I thought I'd post to see if anyone would have an idea. The Input Output Range of the devices are 0100-0100 & 0108-0108

Hi there, I just picked up a CLGD5428 VLB card to replace my ISA GD5429. So far the performance is great, but I seem to have some strange vertical lines on the display. Also in Win3.1 640x480, I get pretty bad flickering/artifacts randomly :( It's a little hard to tell from the pictures, but it's …

Great timing (double entendre intended), as I'm likewise looking at upgrading and maxing out the RAM on my new old 486 system I'm building. The motherboard specs call for 70ns, but what I can find in 72-pin, non-parity, double sided, 5V, 32MB per stick for 128MB total on matching sticks is 60ns. …

Great :D Playing around with the ISA clock speed can also give you decent gains, but push it too far and you get issues. I saw that in your 386 video when you were changing the ATCLK to CLK2/5, the lowest mine will go is CLK2/4, I'm going to do more experiments to see what are the optimum settings …

You can use this benchmark pack: http://www.philscomputerlab.com/dos-benchmark-pack.html I've added a 386 friendly Doom low resolution / details option that works well. It replaced Wolfenstein 3D that I used for a while, but it's easier using Doom because it's shareware and interestingly enough …

Yea I found the same. On a 386, using faster memory, and also cache, can let you use lower timings in the BIOS. But it does also depend a little bit on the chipset. So with fast RAM and Cache you might be able to use the tightest memory timings that the BIOS lets you select. I'm actually test …

How would faster memory cause issues? Just curious what you find with your research. It may be some misinformation from "Arasirsul" on arstechnica: Machines in the 486 era tended to use 80ns SIMMs, which is what you got. Often, memory faster than what the machine expected would cause issues because …

I think it will depends on how fast your processor speed is.(and how fast the motherboard chipset is). On a 386 DX 25 or 386 SX 25 it doesnt make any differents, lower NS memory will do to.. But for the average machines the best way it mostly go with 70ns if you can Lets see the processor is a AMD …

When choosing SIMMs for a 386 machine is faster better? I'm currently running two 1MB TOSHIBA SIMMs running at 80ns each. I want to max out the system at 16 MB and the modules I've found are either 60ns or 80ns. I've read in some research having faster SIMMs could cause problems in the system but …
