A little while ago I purchased a new Corsair case, see it here, undecided and short on cash at the time for other parts. Received in the mail today were several items bringing me closer to having this PC complete. I ended up taking the AMD route this time, which I haven’t done since the AMD Athlon days in the early 2000s.
eBay Purchase Price: $275.50 AUD

Purchased from the same seller as the Creative SBS10 speakers, this was a highly contested item at auction. The desirability of the card was based on a combination of factors, though was a rather uncommon example of finding one with retail box and all. Here I’ve installed the card in one of my 486 PCs.
eBay Purchase Price: $20.50 AUD

After scoring a brand new sound card for my 486 build, a Sound Blaster AWE 64 Gold, it crossed my mind as to the likelihood of finding a PC speaker set of similar vintage. After searching for a while on eBay, the chances looked rather slim. Then out of the blue, these new set of speakers came out of nowhere and fortunately I had won the auction. With the lack of thrift stores compared to North America, finding items such as these makes it all the more challenging.
Lately I’ve been spending some of my spare time on considering my next major desktop PC upgrade.
The combination of having less room at home with a second baby on the way, aging desktops, and enough new standards such as DDR4 and M.2 SSDs, it seemed to be a good time to consolidate and update. While this blog is focussed on earlier computing, it will however be part of the PC I’ll eventually use for further updates here.
“We always overestimate the change that will occur in the next two years and underestimate the change that will occur in the next ten. Don’t let yourself be lulled into inaction.”
That was a quote from Bill Gates’ book, “The Road Ahead”, published in 1996.
I thought it was fitting for this post, after recently coming across a feature article from a magazine (PC Magazine) dating back to June 1998. Describing their predictions for computing in the years 2001 and 2010, let’s see what was accurate, delayed, and just didn’t happen.
In Part 1 of the series, I’ll be covering processors, home network devices, the TV PC, and digital video.
One of my earliest laptops is this IBM ThinkPad 755Cs dating back to 1994. According to the website ThinkWiki this model came with a colour display, either a 486 DX2 50 or DX4 75 Mhz processor, 4 MB RAM, 1 MB Western Digital WD90C24 video, Cirrus Logic CS4248 for audio, and a choice of a 170, 340, or 540 MB hard disk drive.
This particular one was maxed out with the DX4 processor and 540 MB drive, so it fetched some decent coin when new. It had also been upgraded to 20 MB RAM at some point.
Since around the year 2000, LCD (liquid-crystal display) and later LED (light-emitting display) monitors gradually became the de facto standard replacing the earlier CRT (cathode ray tube) technology available. Over the years the size and resolutions of the monitors have increased significantly. These days when selecting one to buy it’s really just about choosing the desired screen size and whether it’s capable of 1080p or 4K resolution. No consideration for colour depth is required for instance.
Of course, during the 1980s and 1990s this wasn’t the case. A series of acronyms were used to give an indication of the monitor’s capabilities, and were frequently stated. Some of these acronyms were EGA and VGA. Over a number of years now low-end or built-in video adapters in motherboards, have no problem with displaying millions of colours on a 1920 x 1080 resolution screen. However, in the past it was more pertinent to ensure that the video adapter was capable enough to handle the monitor’s capabilities or vice versa.
In this post, I’ll be covering from the CGA and MDA standards of the early 1980s through to XGA in the 1990s used by IBM and compatible PCs. Before closing out, they’ll be mention of some of the other standards that became available. PCem is used for many of the screenshots due to the lack of physical hardware.
IBM released the ThinkPad 380 series back in 1997 as a mid-range laptop to use essentially as a desktop replacement. These were part of the long running 300 series dating back to the early 1990s when IBM released a 386 laptop known as the ThinkPad 300. While initially housing the original Pentium processors, the 380 series had typically used a Pentium MMX or later a Pentium II. From what I can tell, these normally were preloaded with Windows 95, though drivers are available for Windows 3.1, NT, and OS/2 as well.
Today I pulled out my two 486 desktops to work on some loose ends that I’ve put off for a while.
The first one with IPC branding I bought earlier in the year from a bloke in Perth, though was missing a serial/parallel port cable for connectivity. I purchased a new one cheaply off eBay a while ago but finally got around to installing it. Now I can use a serial mouse.
The specs are fairly modest for a 486. It runs a PcChips M918i motherboard (also sometimes known as a Amptron DX-9300) with fake cache chips that were relatively prevalent in the early 1990s. Not ideal, but these days I’m thankful for having a working 486. Still I consider having PCI slots and using a replaceable coin battery instead of a soldered barrel of acid positives with this board.
