Hong Kong To-do:
edit purge
  • Clean up all MTR station pages. They are literally all over the place. Two model pages are Tsing Yi Station and Sheung Shui Station. They each describe a feature special to the station, Station layout, exit, and connections, as well as neighbouring stations and the station "box".
    • We will also need plenty of updated pictures (e.g. removing all KCR-related images except those on the KCR article). Check that all pages have basically the same language structure as Tsing Yi Station and Sheung Shui Station. Links to location maps are good too. (Should also perform these checks on Chinese Wikipedia.)
  • Clean-up pages that link with TVB, especially its series pages.

The picture shows the name on the processor itself with a capital B: DragonBall. Shouldn’t the article do the same? —Frungi 22:48, 28 September 2005 (UTC)

Indeed it would. Freescale declares the processor as DragonBall, so I did the rename. --Arny 09:13, 23 October 2005 (UTC)

Someone put this note on the main page:
[Quick reader note: The Motorola 68k was 16-bit so the Dragonball -- which is fully 68k-compatible -- should also be 16-bit. I wish I could find clarification of this. The ARM CPU range is however 32-bit.]
You were right, I've corrected that and included the actual specifications from Freescale. --Arny 09:13, 23 October 2005 (UTC)


The DragonBall is 32-bit:

  • It's listed as 32-bit on Freescale's website.
  • The Motorola 68k is not 16-bit. The first implementation of the 68k architecture (the 68000) was implemented with a 16-bit databus and a 16-bit ALU (IIRC), but this was hidden from the programmer, and the architecture has always been 32-bit, including 32-bit registers and instructions that operates on 32-bit datatypes. Later implementations of the 68k-core was implemented with a 32-bit ALU, and a complete 32-bit data and addressbus.

[edit] VZ speed?

Was it really 37 Mhz? The one in my Palm m515 runs default at 33 Mhz.

I think you're right: Freescale website says 33 MHz, 5.4 MIPS. Letdorf 10:37, 9 November 2006 (UTC).

[edit] Name Origin

Did the name DragonBall Have anything to do with the DragonBall manga series. I noticed that three of the models have 'Z' in the name.

[edit] External Address Bus

It is a 16-bit processor with 32-bit internal and external address bus (24-bit external address bus for EZ and VZ variants).

Found supporting documentation for EZ at http://www.freescale.com/files/32bit/doc/prod_brief/MC68EZ328.pdf?fsrch=1. Can anyone verify VZ? - MSTCrow 22:37, 12 January 2007 (UTC)
