Talk about the history of the keyboard 40: DELL Dell SK-8100/SK-8110/RT7D00/RT7D20 membrane keyboard

1 Introduction

This time is really the last issue of DELL's SK-81xx series keyboard. It really is... This time it's about DELL's SK-8100/SK-8110/RT7D00/RT7D20, SK-8100 corresponding to RT7D00, The SK-8110 corresponding to the RT7D20 is the Asahi and NMB OEMs, respectively. The same size of the two keyboards is actually only a little different in appearance, SK-8110 put 4 function keys to cut off. This keyboard can be said to be the originator of the SK-81xx. It is a model farther than the SK-8115, but it does not use a narrow frame design like the SK-8115 in appearance. Since the version of Asahi OEM is relatively rare, the UP master only has NMB OEM's RT7D00 and RT7D20. They have blue and gray colors and are non-US, so this issue introduces RT7D00 and RT7D20, respectively. Four keyboards.

2. Appearance

The following keyboard sequence is RT7D00 (gray) / RT7D00 (blue) / RT7D20 (gray) / RT7D20 (blue)

The four keyboards are in bulk and there are no boxes.

Three of the keyboards are European-style and the US version is RT7D20, a standard 104-key layout. The keyboard does not have a narrow frame design like the SK-8115.

It can be seen that the two keyboards are the same in size, except that the RT7D20 has hacked off the four function keys.

The RT7D00 uses an undercarved engraving LOGO. It also has three function keys that are simple and functional. On the right side of the F area is the sleep key. (Design is very fucked in this position. If you accidentally touch, you sleep. )).

The RT7D20's LOGO is only printed.

NMB is divided into two production bases in Thailand and China. In general, the Thai production has a better feel. We can see that RT7D00 is produced in Thailand and RT7D20 is produced in mainland China.

There are two rubber non-slip stickers under the back of the keyboard, the effect can only be said in general.

Although the RT7D20 cut off the function keys, but at the same time in some places to improve, such as the RT7D20 increased drainage holes.

The two keyboard footers are all one-step open and feel elastic.

Two keyboards use a crater structure. According to past experience, the SK-8100/SK-8110 structural model of Asahi OEM will be slightly different.

The keycap is made of ABS material, easy to oil, the same model of the two keycaps.

The font is a silk screen transfer process, and the RT7D20's screen process is even better and more violent. The key cap surface is estimated to have a coating that feels a bit like skin and feels very good.

Cap wall thickness RT7D00 (gray) = 0.7mm RT7D00 (blue) = 1.0mm RT7D20 (gray) = 0.8mm RT7D20 (blue) = 0.8mm , much thicker than the subsequent replacement models introduced in previous issues, in particular KB522 Only poor 0.4mm.

Rely on the height of the keycap to achieve ergonomics.

Because the back of the keyboard is a curved design, the keyboard is not small.

The height of the back of the keyboard itself is relatively high. After the foothold is opened, the entire tilt angle of the keyboard is larger. Now the alternative model is more and more reduced, and the foothold is almost identical to the egg.

As the model is relatively old, the PS/2 interface is used for the keyboard, and the wire diameter is about 4.2mm, and the data is solid.

Weight aspect RT7D00 (gray) = 725.4g RT7D00 (blue) = 728.9g RT7D20 (gray) = 747.8g RT7D20 (blue) = 740.7g . In terms of weight, RT7D20 is about 20g heavier than RT7D00, which seems to be better than expected.



3. Summary

RT7D00/RT7D20 these two models can be said whether in the design or the material compared to the previous few slag replacement models simply conscience to the home, the worst material KB522 cap wall cap only 0.4mm diameter only poor 2.9mm , And this section of the keyboard cap wall is about 0.7mm-1.0mm, wire diameter of about 4.2mm, but also does not have the same key short-range key. In the feel of RT7D00 and RT7D20 difference is still quite large, RT7D00 significantly softer, and RT7D20 is much harder, harder feel led to a stronger point in the sense of resilience and paragraph on the RT7D20, as a whole are two types of keyboard are The tea axis feels, but the RT7D00 feels more comfortable. The RT7D20 has been improved in some places compared to the RT7D00, such as increased drainage holes, better keycap fonts, and heavier weight (generally the heavier the weight is, the better the material is).

The keyboard has been discontinued for a long time, and the richest family could not be found. Only one company is selling in bulk, but it is the European version.

The next notice: Say this is the final period of the SK-81xx series, although the next period is still DELL keyboard, but it is AT101W, ALPS mechanical shaft.
