replies: text: No, that image has too much Japanese text in it to be intelligble to those of us who don't read Japanese. But the article does need a block diagram of some kind.--Wtshymanski 21:41, 18 September 2007 (UTC)
thread_title: Illustration needed

message: Is there more to explain about bank switching in 
video processing?  As I understand, the issue there 
is timing rather than address size.  Isn't one page 
displayed while another is drawn; the fresh page 
only displayed when complete?  Thanks to anyone 
who can explain more.   ... PeterEasthope (talk) 22:46, 22 February 2008 (UTC)

message: The article doesn't describe the philosophy or technique of the bank switching. It just explains how useful it is, but nothing about its usage or how the "trick" works. pictureuploader (talk) 18:20, 7 December 2009 (UTC)
replies: text: I've added a diagram but I should also add some explanation of how it would work. Some magic subroutine must live in common memory that keeps track of what bank is currently active and what bank is next to be accessed; then the subroutine must set up some memory controller hardware that controls which chips actually get to respond to the CPU memory access cycles. It's a start, anyway...--Wtshymanski (talk) 02:10, 27 March 2010 (UTC)

thread_title:  Microcomputers 

message: Bank switching did not originate with PCs, and statements specific to microprocessors, or to specific microprocessors, belong in appropriately labelled sections. In particular, Bank switching#Technique should be generic. Historically bank switching used an internal register for the bank number. Shmuel (Seymour J.)

replies: text: In what way is Bank switching#Technique PC-centric? The techniques described appear to be the ones used on Z80 CP/M machines and on the Commodore 128 as well as the early PC ISA extended/expanded memory cards that cam out when large Lotus 123 spreadsheets started using more than 640K. -Guy Macon (talk) 16:11, 3 June 2020 (UTC)
replies: text: Because it assumes external bank registers and microprocessor support chips. IBM marketting notwithstanding, I consider, e.g., the S-100 bus machines, to be PCs just as much as the IBM PC, and the Techniques section ignores everything earlier than that. The whole section needs to be separated into generic material and material specific to particular systems. Shmuel (Seymour J.) Metz Username:Chatul (talk) 18:34, 3 June 2020 (UTC)
thread_title:  [[WP:NPOV]] - too PC centric and ahistorical 

message: Intro section says:
"Unlike memory management by paging, data is not exchanged with a mass storage device like disk storage. Data remains in quiescent storage in a memory area that is not currently accessible to the processor (although it may be accessible to the video display, DMA controller, or other subsystems of the computer) without the use of special prefix instructions."
It is presumed paging is the same as page swapping, which is incorrect. Paged memory can work without a backing secondary store and is indeed a memory management technique, a more modern one but not completely unlike the cruder technique of bank switching. A better intro should be provided if someone can find a good source.

thread_title:  Problematic definition in the intro 

message: Was the DEC PDP-1 (1959) the first computer to use bank switching? IAC, the article should mention it and the more common CDC 3600 (1963). --Shmuel (Seymour J.) Metz Username:Chatul (talk) 10:01, 1 June 2022 (UTC)
thread_title:  History - was PDP-1 first 

message: The article makes an incorrect statement regarding the Sega Genesis/Mega Drive usage of the technique. While Super Street Fighter 2 did have more than 4MB in size, there weren't "several" cartridges that also did so. Actually, during the console's lifespan, SSF2 was the lone game to exceed the maximum size. And only five aftermarket homebrew games (Pier Solar and the Great Architects, Paprium, FX Unit Yuki: The Henshin Engine, Demons of Asteborg and Astebros) surpassed that value, making them just a handful, not several more games.
