Talk:Hitachi 6309

Hirotsugu Kakugawa
I'm putting his name back with the proper spelling. I'm not fluent in Japanese by any means, but "Kakugawa" is a sensible spelling and Kakagawa is not. Please refer to the link on the page where his original postings are archived on Google Groups. -- Lamune 03:25, 20 May 2006 (UTC)

Intro Paragraph
I rewrote it, I think it flows better this time. You be the judge. 00:21, 22 May 2006 (UTC)

speed comparisons
It would be interesting if someone posted a cpu comparison to other cpus such as the 68000, 6502 ect. If somebody does it, I hope it is acurate and isn't rigged to make one of them look better than it is. Cpu comparison charts are can be so easily manipulated sometimes.

From: 75.57.187.99: "Compared to other less related cpus, it is somewhat faster than a 68000 clocked at equal speeds, but is much slower than a 32-bit SuperH or an ARM risc cpu." I don't think this should stay unless a good reference is cited. Tlindner (talk) 04:31, 4 March 2009 (UTC)

For object code which takes advantage of the efficient addressing modes (present in the original), and which doesn't take advantage of 32 or 64 bit advantages of more modern processors, a fast 6309 will do quite well. For anything which depends on I/O speed, modern buses and memory speeds will leave it in the dust. Emulation is likely the best way to go... 69.118.209.149 (talk) 06:19, 30 December 2016 (UTC)

Seriously, why do you always delete what I write less than 5 minutes after I write it, yet you let other people write retarded lies all the time and do anything about it, and keep it up so long that 200 websites already say the same information, and you delete my stuff after 2 minutes?

production question
Is the Hitachi 6309 still manufactured today? Retailers seem to carry them in the thousands. This would be a valuable clarification to this wiki page IMHO. —Preceding unsigned comment added by 173.66.219.167 (talk) 01:33, 26 October 2009 (UTC)

Static vs Dynamic
Someone a long time ago claimed that the device is "fully static": https://en.wikipedia.org/w/index.php?title=Hitachi_6309&oldid=48448210 That's wrong. The datasheet specifies a minimum clock frequency of 2MHz for both the HD68B09 and the HD68C09 and they will lose their state when the clock speed is too low. Source: My eyes. But in all seriousness: https://electronics.stackexchange.com/questions/474253/fully-static-hd63b09ep-loses-state-when-clock-is-paused I changed the article to reflect that, but I am unsure whether my writing style is appropriate. I would appreciate it if somebody could check that.
