message: So what's with the removal of the category? I don't know of any policy against categorizing microprocessors, so removing a category should be just as bad as deleting correct content. Stan 16:27, 15 Jul 2004 (UTC)

message: I've added all that I know about the 6800 (having at least programmed them when I was younger).  I could not find more information about the designers- if you know more, please add the information.

thread_title:  M6800 Patents 

message: Anybody knows why it's called 6800? I know it follows common number series of that era (think of Intel 8000/8080 or 82xx series, "TTL" 74xx, etc.). I'm just wondering if 68xx was the next product line after "67xx" or how they came up with that number. Or was it just the marketing department at Motorola that wanted the product(s) to look 'technological' & 'hi-tech' so they opted for a labelling and marketed it in accordance with that era's "way of doing it"?

thread_title:  The name 

message: The big thing lacking from most of these microprocessor articles is the pricing. Initial pricing at the time of release is the absolute must. Usually these prices varied according to the quantity ordered. Also, if the info is available, it would be good to see how the price changed through the years. Maybe a section on Marketing is called for to contain this information. JettaMann (talk) 14:27, 10 September 2010 (UTC)
thread_title:  The Pricing 

message: Hi all, I was advised to come here by User:swtpc6800 to not "use an ambiguous template". So, the article needs to get some wikilinks inside it. It's (very?) well-referenced, but there was not even a link to Motorola, the manufacturer. I'm not familiar with microprocessor articles, so I don't know if the sections/text is up to scratch, but for general readers... I'd say it needs a bit of work, for example there's no explanation of common computer terminology (RAM, ROM, ICs [I had to look it up, I guess this is the correct meaning??], I/o, etc) and the article seems a little complicated at first glance.
When I have some time I will be coming back to improve the article where I can, although I think a template would definitely be helpful for any editors, as it's easiest indication of a 'to-do' list on an article :) - ChrisWar666 (talk) 19:45, 13 July 2011 (UTC)
replies: text: Usually the "Wiify" tag is applied to blocks of text that have no formatting or internal links at all; it's not as useful in flagging an article that already has some internal structure and links.  If you find you have to look up a term to understand it, then that's a good term to have as an internal link. --Wtshymanski (talk) 20:43, 13 July 2011 (UTC)
thread_title:  Wiki 

message: The article states that the 6801 had 10 new instructions but it looks like the datasheet lists 16. I could not find the "Product Preview MC6801" attributed in the references to confirm.97.40.64.122 (talk) 04:38, 29 October 2017 (UTC)
thread_title:  6801 instruction count 

message: This article mentions a few uses in the microcomputer field, but fails to mention the obvious - the 6800 was pretty much unused compared to the competition from Intel, Zilog and MOS. Cost was certainly one factor in this, at least until the 1976 time frame when that fell to be similar to the 6502, but that doesn't explain it all (especially considering the 8080 was a similar price yet required a more complex 3-voltage supply).
The part that's missing is performance. On every contemporary benchmark - and there's not that many of them so it's difficult to find - the 6800 invariably finishes behind every other CPU. The Rugg/Feldman_benchmarks are a BASIC test, and one can see the difference a change of the interpreter makes, but comparing Altair BASIC 1.1 times (MS 8k w/strings) on the Altair 680 and 8800 one can see a significant difference in performance.
By the time the Byte Sieve rolled around the 6800 had already been abandoned, but even the 6809 puts in a terrible show, being outperformed by the PET of 4 years earlier.
I think this needs to be mentioned, so if anyone has additional sources from the era that would be very useful.

thread_title:  Relatively unknown in the microcomputer field, why? 

message: The current page includes a paragraph that says the 6801 contains a 6802 core, which is a mistake that can be verified by examination of relevant manuals and data sheets. As mentioned in the talk section about instruction counts, the 6801 includes new instructions. See the 6801 reference manualMC6801 8-bit Single-Chip Microcomputer Reference Manual MC6801RM(AD2) and compare with, for example, the 6802 data sheet"6802/6808/6802NS Microprocessor with Clock And Optional RAM" available in various places on the web.Reiisi (talk) 03:42, 21 September 2020 (UTC)
