HGFX HAM Vandalism[edit]

Do not revert the article about the HGFX HAM. You did not give any relevant explanation. The sentence "Not about the Spectrum" has no relation to the HAM technique. Any relevat comment, e.g. how the HGFX HAM is close to the Amiga HAM, are welcome. Are you involved in debates about the start- and end- pixels and colour markers of the HAM (as the author of the DaDither did in many discussion forums?) Do also study and test practically, before any deletion: https://www.dadither.com/ 89.203.142.224 (talk) 14:43, 31 December 2023 (UTC)[reply]

The article Hold-And-Modify is about the Amiga mode. Graphics modes on the ZX Spectrum are not relevant here. Feel free to put a single link to a relevant article in the See also section but don't elaborate undue and misplaced details about a totally different system. Also, Talk:Hold-And-Modify is the right place to discuss any of this, not here. And if you keep accusing me of vandalism I'll report you. --Zac67 (talk) 15:22, 31 December 2023 (UTC)[reply]

You are not supposed to chat about the article in Talk pages. Smallcat101 (talk) 00:25, 15 February 2024 (UTC)[reply]

OSI model[edit]

Hi You removed my commit, can you please expand on it? Is it only the "Layer 0: " you don't like?

=== Layer 0: Physical media ===
ISO/IEC 7498-1, refence to physical media as:^[1]

"provides the means for transfer of information between open systems" (4.2.8)

Is part of the four elements that is basic for the OSI-model (5.1.3).

The lowest layer abstracts the physical media that connect them (5.2.2.4)

Real subnetwork, is a all the equipment and physical media, which forms a autonomous system (7.5.1.1).

This includes:^[2]

Cabling infrastructure

Wavelength-division multiplexing

Radio

Whatever Belden's marketing writes, there is no layer 0 in OSI. The physical media are all layer 1, the physical layer, , see ISO 7498 clause 7.7.

And we're not discussing this here but in Talk:OSI model. --Zac67 (talk) 06:28, 4 April 2024 (UTC)[reply]
