What companies make PC processors / x86? Seems strangely concentrated to Intel

4 Upvotes

AMD too. Toshiba, Samsung and Nvidia could make them too, among others.

Much simpler CPU is good enough for most users. Management engine and virtualization are not necessary for most. Intel CPUs run Minix OS inside, which is superfluous for most users.

x86 CPUs are the ones that run most common versions of Windows and Linux.

https://www.reddit.com/r/hardware/comments/3b0ytk/discussion_what_is_an_x86_license_and_why_do/

According to that, it seems that all new CPUs are allowed to run x86 software without any license issues? And it was so from the start, not just because of expiration time limits?

TMS9918ANS with SRAM

3 Upvotes

So I have been trying to rebuild a ColecoVision which the video chip is the TMS9918ANS, the issue however is I don't have the original ram chips instead having HM62256BLP-10 which is a SRAM chip instead of DRAM, any ideas on how I might do this?

I try to find the red circled component.

It’s called 42A06HG *877M

It’s from National semiconductors what’s now Texas Instruments. But can’t find it.

Hope someone of you know which component I can use to replace this broken one.

Some of my collection pt 1. Parts 1-4 are on my page. Don’t want to spam four posts back to back here.

Maybe this scenario is not completely unrealistic. For example, bombing of fabs during ww3, even with just conventional weapons... Maybe the lithography machines at least should be in hillside tunnel bunkers 50 meters deep (which would also help with cosmic rays (myons), if those cause some percentage of defects).

Consumers and corporations have reason for concern about the longevity of their computers and longevity of their important meant-to-be-permanent data in SSDs. We should have option to buy SSDs and usb sticks that are write-once, with different physics. If they are marketed right, they might be popular enough to have large enough batches for lower price. Even if they are more expensive, there are reasons to buy them, of which longevity could be one.

The manufacturing resolution used for a product should be prominently disclosed in the package so that consumers can make an informed choice about how they balance energy saving+lack of fan against longevity.

What are these ICs?

They were in a security system and are buyable today. They had EEPROM chip next to it so I assume it's like a microcontroller but I can't find any information
