"Peddle suggested that anyone that actually required this style of access could implement it with a single 74158." I don't see how that would work with just one, the 74158 is a quad 2-input mux, the bus is 16 bit. Thesource doesn't say "single" either, just "a". Someone with better knowledge of the topic, please fixAecho6Ee (talk)08:04, 12 November 2023 (UTC)[reply]

Yes it looks like you need four of them. More usual would be tristate buffers like the 74367, but the MUX are fine, too. Many of the early chips, and I didn't look up this one, could barely drive one TTL gate.Gah4 (talk)21:05, 12 November 2023 (UTC)[reply]

It seems that the Reset Pin in the pin configuration picture is wrong. It should be inverted. That means a Dash should be drawn over it, similar to the NMI and IRQ pin.WhyLee (talk)09:19, 30 April 2025 (UTC)[reply]

@WhyLee: Thanks, you are correct. The problem needs to be fixed atcommons:File:MOS6502.svg. The diagram appears in the article atMOS Technology 6502#Technical description. I would not be able to look at fixing a diagram for a month. Someone atWP:HELPDESK would be able to recommend how to ask someone to fix it.Johnuniq (talk)10:07, 30 April 2025 (UTC)[reply]

@WhyLee: OrWP:BEBOLD and update the picture yourself. You'll discover/learn along the way.RastaKins (talk)20:41, 30 April 2025 (UTC)[reply]

In the Furby article, in the technology section the original model's use of the 6502 is mentioned. Could that be brought into this article?Anamyd (talk)16:48, 1 May 2025 (UTC)[reply]

It appears that the original Furby did not use a 6502. It used a Sunplus SPC81A. This microcontroller has a huge 80K of ROM and 128 bytes of RAM. Although the architecture of the SPC81A is similar to a 6502, it is missing the Y register. The Furby source code is readily available on the internet. It seems like a beginner wrote it. (RAM is allocated with equates and most of the code is loads, stores, and jumps.)RastaKins (talk)15:38, 2 May 2025 (UTC)[reply]

What is this suggestion that the history of 6502 somehow goes back to 1960? The whole paragraph is too farfetched, and does not really have anything to do with 6502. Some of it related to the personal history with Peddle, but that is about Peddle and not about 6502. The section needs to be rewritten or removed.~2026-81565-2 (talk)04:55, 6 February 2026 (UTC)[reply]

I think the conception section needs a delete. This whole fanciful section was written by a single editor and started with this edit:

18:48, March 5, 2025 Chadalvarez2021 119,718 bytes +1,228 →History and use: Attempting to find further origins about the 6502 and what led Chuck to begin designing new technology of the time (I'll let you now when I'm done)

If anything, it should be in the Peddle article but I am not sure the cites are adequate for that.RastaKins (talk)16:13, 6 February 2026 (UTC)[reply]

I havebeen bold and trimmed out some of the stuff less relevant to the 6502 specifically. --Wtshymanski (talk)19:42, 10 February 2026 (UTC)[reply]
