x0x 231 — Complete

[This is cross-posted from here because I am too tired / whatever to write a new post for here right now.]

x0x 231, my x0xb0x, is complete. After a fair bit of work and a lot of waiting (mostly for the new artwork to be printed) it’s done.

If you would like to see photos of various phases of my x0xb0x building — including stuff relating to the new artwork — please head on over to my x0xb0x photo gallery (photo gallery retired) and have a look around.

As you can see, I made some new artwork for my x0xb0x. I ordered a few extra pieces, and most of them have been reserved by others, but if you’d like one, email or private message me. I have three pieces left, and as I am making no profit on them, I will not be placing a second order.

The cost for one of the panel overlays is US$41 and includes US Postal Service Priority Mail within the US, and one of the red keycaps you see above.

As far as the rest of my x0xb0x goes, if you’d like to make your x0xb0x like mine, you also need to do the following things:

– Add a power switch.
– Replace R1 with a 200 ohm resistor to make the PS a bit more noisy.
– Replace all LEDs with red diffuse ones. (Digi-Key Part 67-1105-ND)
– Replace all the resistors tied to the LEDs with 820 ohm ones (Mouser Part 291-820-RC)
– Paint the rear panel black.
– Design a new overlay for the front panel and use a red keycap for the RUN key. (As if this one wasn’t obvious…)
– Replace all ‘important’ transistors with ones with ‘high beta’ ones as follows: Q10: 338, Q9: 338, Q8: 349, Q36 & Q38: 335, Q27: 337, Q33: 331, Q1 & Q2 & Q31: 327
– Replace the rotary switch knobs with knurled matte black aluminum ones. (Digi-Key Part 226-4090-ND)

And… That’s all I can remember for now.

I must say, though, I’m glad it’s done.
