From the video description:

A CPC6128 was built in a Desktop case. It got the following additional features:
- 20 MB Dobbertin HD20 hard disc
- Dobbertin 512 KB memory expansion
- 224 KB Dobbertin EPROM expanson
- Dobbertin Time-ROM with RTC (switchable)
- 5.25" HD floppy, 40 / 80 Tracks switchabel, side switch
- A-B switch for 3" and 5.25" floppy
- Mouse port (delivering 5 Volts, also for Autofire-Joysticks)
- Regular video output, VHS and S-VHS video out, Multisync monitor
- Two seperated Joystick ports
- Switch for AMSDOS or X-DDOS
- Reset button
- 50 Hz / 60 Hz switch
- Bigger internal speaker
- Seperated keyboard, either from Amstrad or Siemanes
Eventually it's a great system for serious work, gaming or to run FutureOS. FutureOS does actually support all the included hardware.

What keyboard do you use with it?

Either a keyboard from the CPC6128 or a Siemens keyboard (which has some advantages, for example no keyboard clash).

And some disadvantages, like input lag. But since you said it's to use the CPC for productivity, the input lag is not an issue.

Well, ...

- There is no input lag, because the keyboard is connected directly.

- Yes, it's a CPC, faster compared to most PCs in real life, so I'm glad there is no keyboard lag.  :D

Directly to the normal keyboard connector? Did you wire the keys yourself?

What you mean directly? If you use the same PPI lines than for the CPC keyboard, how is that you don't have keyboard clash?

That's an extremely vague claim. What exactly is faster? Because the only way to compare completely different systems would be to compare MIP's and I can't think of any way that a CPC would faster than even a 90's PC.

eto and abalore: The Siemens keyboard is different, therefore no clash.
Yes, it needed a bit of reworking connections, but the keyboard itself makes it pretty easy.

Bryce: No intention to have the same discussion once more. I talk about real life, no abstract technical specs.

No idea, what you are talking about. As there is no keyboard buffer in your routines, things like the texteditor are completely unusable (when you type in fast, half of the chars are missing).
An actual PC is about 1 million times faster/more powerful than a CPC - even in real life.
Everyone can love our CPC, but telling stupid things doesn't help at all.

It probably has diodes in its matrix. You can get full n-key rollover with a diode next to every key switch.

Exactly! That Siemans keyboard has that. And therefore no keyboard clash either.  :)

Exactly! So please stop telling stupid things!  :P :laugh:

If you want to start a "FutureOS bashing" thread please create a new one, instead of derailing this one - once more.  ::)
