Star Micronics Colour Dot Matrix Printer Unboxing (dot matrix printing)

I picked up this 1989 Star Micronics NX-1000 dot matrix printer from a recent computer warehouse haul in Auckland. There’s a good chance it hasn’t seen much use in 25-ish years, but I was surprised to see that it came in its original box. During the unboxing you’ll see that its manuals and cables all present and correct, so I had hopes that this epson compatible printer might work.This lovely little printer was one I was familiar with from primary school back in the day of the BBC micro, and it was a very nice machine back in its day.

10MHz V20 XT vs. a 6 MHz 286?

Here’s another quicky video! Call me dumb but I had no idea whether an XT-clone PC XT rated at 10MHz NEC V20 CPU with an 8087 co-processor, or an XT machine with a 6MHz Intel 80286 CPU and an 80287 co-processor would be faster. Surely logic would say that because 10 is bigger than 6, that’s better? Surely an 80287 would be better than an 8087? Right??? Well, the results may surprise you. Of course, the results are all 100% scientific. Legit scienciefied. The final benchmark which concludes everything is the old ‘Which one loads up Leisure Suit Larry 3’ test. Y’all know that one, right? 😉

Documentary: How and why IBM made the first PC

IBM released the IBM PC 5150 in 1981. Internally, IBM went through massive hurdles to get a personal computer to the market to compete with the other microcomputers of the time. This documentary shows all of the happenings organisationally as well as the trade-offs and decisions that led up to IBM choosing the sluggish 8088 CPU.

ST506 Drive ‘Find’

I recently took ownership of a banged-up old #IBM PC XT. The motherboard was toast, the case was all banged up, so I decided it wasn’t worth repairing after many hours wasted with a multimeter and desoldering.. I put a new old 10MHz Turbo XT clone board in and it complained about some boot issues. So whilst I was debugging the issue, I thought I’d put the #ST506 hard drive in from the old machine. I didn’t expect it to work, but I thought just having a controller in there might help the issue. What I didn’t expect is that the 25+ year old drive would actually work. To my amazement, it (almost) worked first time. And here’s the treasure trove on it. Always find it amazing just seeing what people leave behind on their computers. It’s like a time capsule. Apologies for the really rough video, I shot it on my phone with no mic or anything, I just recorded it live as it was happening as I didn’t know if the disk was going to crap out on me. Didn’t have time to prep

How to play music modules on an old PC (MOD/S3M/XM)

Up until now, listening to digitised music on a retro PC has been pretty much impossible. In this quick video, I’ll show you how you can play MOD / S3M / XM modules on a PC with as little as a 4.77MHz CPU. This is using brand new software (March 2020), which is still in beta so YMMV!

MS DOS Shell & Task Swapping Review

Many people didn’t even know that a utility called MS-DOS Shell shipped with the extras disk of MS-DOS versions 5 & 6. It was a handy file manager which looked and operated similarly to File Manager in Windows. One of it’s most interesting features was its ability to ‘swap tasks’. I’ll show you how to enable task swapping, and how it works, as well as give you a brief overview of the use of Dosshell overall.

How to get more than 640K RAM in a PC or XT

For years, I thought that it was impossible to access any more than 640K ‘Conventional’ RAM on my PC or XT. I was wrong. This time on Al’s Geek Lab, we see why and how the PC only addressed 640K, as well as how to take it up to 1MB without any major work.
