The drawings will take at least a couple of days to complete. It is proving difficult, but not impossible, to measure such small objects. The tops of the keys have the edges slightly rounded, but the radius is much less than the minimum radius I can measure accurately (1mm).

The scans I made from each side of the keyboard show the lower edges of the keys to have been polished away, leaving a vertical skirt of 1mm or so at the bottom. If it were not for this, the keys would measure 18.5mm square across the base.

I have three A500s and an A500 Plus. Strangely, this feature is more evident on the later keyboards, so it cannot be due to wear and tear. Indeed, the earlier keys are much sharper at the bottom edges, so that those keyboards appear to have less clearance between the keys.

The drawings will depict each of the five unique key profiles. For clarity and best accuracy, only the four edges will be shown dimensioned with the angles between them specified.

The effects of rounded edges and polishing will not be shown. I know nothing about how features like this are incorporated into the rendering, but I imagine that the extent to which these are implemented is best chosen at the rendering stage to give the most pleasing result.

I understand fully if you can't measure stuff less than 1mm, and that's not necessary either. About the rounding I think it should suffice if you scan the top and bottom of one key. Beveling/rounding could be done in a bunch different ways. It may be easy or superhard to change depending how far you are with model. But I'll do some test renders to see if we're on the right path.

Hi bLAZER,

Here are 600dpi scans of the ESC key. This key measures 18mm square at the base, and the top is 12mm wide x 14mm deep.

I'll try to get the drawings completed and uploaded in time for the weekend.

Wow! With so perfect measures you could make this model in 3D.

And here's a video really interesting for modellers about it:

I found it in this incredible project that you have to read too:

Pretty cool C-64 model there... it's still a bit expensive to print 3D models though, but prices are dropping of course.

Hi bLAZER,

I'm uploading the drawings to The Zone for you now.

The drawings show the left side profiles of the keys in Rows 1-4 and 5&6, where Row 1 is the front row and Rows 5&6 are the back two rows.

I made the drawings at 10x scale and then scanned them at 150dpi.

The dimensions and angles are given in the table below. The back of each key is shown on the left and the front on the right.

Code:
Row          1        2        3        4       5&6

Top        14.0mm   14.0mm   14.0mm   14.0mm   14.0mm
Back        8.5mm    8.0mm    8.0mm    9.0mm   10.5mm
Front      13.0mm   11.5mm   10.5mm   10.5mm   11.5mm
Base       18.5mm   18.5mm   18.5mm   18.5mm   18.5mm
Top Back    113     110     105     100      97
Top Front    92      97     102     106     106
Base Back    83      82      83      84      85
Base Front   72      71      70      70      72

Excellent work! I'm off work for 4 days so I'll have plenty of time for some modelling.

OK, so I think I got all the keys modeled pretty good (not shift, alt etc) but do you think you could measure somehow the angle they are layed out? Either the angle or if you measure the distance from the bottom to the top of the front and back. See the image. (As you can see the keys are not aligned properly.

The angle is 13, but it looks like you have the keys reversed, i.e. the back row keys at the front and the front row keys at the back.

The views I drew were from the left side of the keyboard.

Edit: But you will find - even when you turn them around - that the tops of the keys don't align properly, as my scan from the left side of the keyboard showed.

Ah, I forgot about those two photos from you... will do some adjustments though, and thanks for the angle!

You were right, I had the keys reversed. Now they look pretty good and fit well. The only think that I had to eyeball is the curvature of the key and the bevel. I think it's good to go now.

Yes, I agree. That looks quite realistic now.

Yeah, with some minor tweaks and a better material I think I will look fine and dandy.

For the love of god STOP, have you not seen the matrix? You are making it too easy for the machines to recreate the peak of our civilisation!

This goes double for you Toni Wilen if you're listening, seriously, you better quit it before some leather clad hackeress comes knocking . . . .ah wait . . . now I see what you're up to, night after night, sitting at your computer, you dawg.



Amazing stuff though, the grimy tank mouse looks amazing, if I hadn't been tipped off I'm sure I would have though it was a photo. Look forward to seeing the finished 500. Are you a professional bLAZER?

No, I'm not doing any 3D in my day job, just programming and some 2D.

So, the keys are looking pretty good now, just the two enter/return keys left to do. Also the Del/Help keys doesn't seem to fit exactly as they should in the cut out, maybe I measured the hole wrongly. I'll check again otherwise I'll adjust so it'll fit, no one will notice anyway.

Wow! That looks just like my photo now, except for the different viewpoint. Great work, bLAZER!

Thanks! I'm gonna wait with the texturing for the keys because after that's done there's no turning back, and maybe I find something that I want to change.

So when you have some time over it would be nice if you could do some more measuring of the body.

Okay, But the rest won't be given the same priority as the keyboard area, as this was (for me) the most difficult part. I'll continue with this as and when I have time.

Next, I will measure the rest of the features visible in my photograph of the top. The remaining measurements will be much easier to describe, being made in a plane parallel with or perpendicular to the surface of the body.

Then, I'll photograph the two sides and provide measurements, followed by the back and then finally the base.
