    16:13 It's interesting to see how the game fills the first page of graphics and then switches to the other. We can clearly estimate around 1.5fps in the flight sim.

      That is a really interesting insight and IIRC, SubLogic claimed 2fps at the time. Thanks for watchng :)

    This was the first computer I bought new. Why? I was young and didn't have a lot of money and this offered a pretty good value. Full-sized keyboard. The two 720K floppies. A screen. Software bundle. Case. And the 2400 bps modem. And 640k ram. For me to buy all this functionality in the day in an IBM or compatible, I'd have to spend a lot more. I'd have to buy a monitor, spend to upgrade to 640k ram, upgrade to a 2400 bps modem and buy software. So for me, it was a good value. I still have it. I bought a second one that I have played with. I removed the clock chip and put in a RTC. I build an expansion board for the back and can run/boot from a Compact Flash card. And I have screen to run color CGA by replacing the mono LCD SuperTwist.

      Exactly! Despite it's unusual appearance the machine was actually capable and good value. I'm very tempted to do a screen upgrade :)

      @@backroomboy4420 Well, I have the screen to do it but I have not installed because of the expense of the CGA TTL-to-VGA convertor. I can't afford to dedicate one to one computer. Unless I am wrong, the convertors are running about US$100. We (vintage computer enthusiasts) need to get the cost of these convertors down.

      @@Fezzler61Agreed. There are a number of solutions but none is especially cheap and when you decide to buy one you find they're unavailable because of a shortage of one or more components.

    I had one from new. The screen was awful and it was slow and heavy. But it was cool at the time.

      Ah, you were 'that bloke', the one person who bought the machine new, lol! Yes, despite it's failings, and they are legion, it definitely has a quirky, cool charm too. Thanks for watching :)

    What's it doing with 14 pins just for monitor DC-in? I was sure it was gonna be monitor signal AND power in one port.

      I know, weird right? The 14-pin connector has -5v, -12v, +5v and +12v (of which, the PPC uses +12v, -5V and -12V) as well as a number of ground pins and separates these from the video signals which might otherwise be subject to intereference.
