Chinese consortium Covec was supposed to build A2 highway in Poland for the Euro 2012. Then in middle of construction they quietly stopped paying subcontractors while still receiving payment form the government, and finally moved their staff back to China when whole thing started hitting papers.
so I brought the 3000 home, snapped a shot of the ram and found it's not Sram and it's not Dram it's called static column ram - which is as close to Sram as you can get (but not Sram, yet we called it that).
Its not close to sram at all other than similarly sounding name, as I wrote in previous post it is an improved variant of page mode DRAM: >and here a definition of "static column mode" in case you would somehow think this means SRAM: https://www.jedec.org/standard...
In fact if you search for 9A9Z you get all sorts of answers of what it is.
datasheet: http://datasheet.datasheetarch... a big hints are -a whole timing diagrams section on refresh -multiplexed address bus -fact 4Mbit sram chips didnt exist until 1993, and when they first showed up they were >$140 a pop!!! -and fifth word of the datasheet reading 'dynamic':-)
This ram allows the same search and grab as Sram,
Now we are moving 2 posts back. You are confusing two separate things, type of ram and ability to recover data after reset. Those two are independent.
Both types of ram will keep its data mostly intact over a reset, and somewhat intact after total power loss depending on process size, temperature, time etc.
Difference between SRAM and DRAM is in physical construction. One uses multiple(4-8) transistor latch arrangement - you put logic level in and it stays there until powered down. The other uses _one_ transistor and capacitor and needs frequent refresh (recharging that capacitor).
More transistors to build sram means more expensive, around x10 was the minimum. This is why in the nineties a 256KB sram cache for a PC motherboard cost around the same as 4MB simm. This price difference (and use of slow processors) was the reason not a single Amiga featured sram.
1 this is A500 expansion 2 this is fast ram expansion, Amiga stores images/sounds in the chip ram (separate memory bus) so even if you had third party sram expansion it would do nothing for you because pictures and music was stored in different part of the computer. Amiga rasterizer and sound chips had no access to fast ram (where this particular sram extension installs). https://en.wikipedia.org/wiki/... 3 again - what you described (reset to rip memory content) _never_ required special memory type. You could do it on C64, Amiga, Atari, even consoles. 4 pointing at third party products to corroborate your faulty memory is like claiming Honda Civics came with Spoon engines, T66 turbo, NOS, and MoTeC system exhaust.
Got a late start eh, I don't think many on/. haven't worked on computers
cute:)
I get it man, you miss remembered something and now just cant let go. Its ok, its not the end of the world. I will leave you and your cognitive dissonance in peace.
there is no sram in amigas (except for 768 bytes of palette inside Lisa chip) The difference between sram and dram is _not_ that one of them can keep the data over a reset, its that one of them keeps data without explicit _refresh cycles_ when rest of computer is powered down completely. Reboot is not doing ANYTHING to ANY type or ram. Resetting a running computer without stopping current program was standard on Intel 286 (dram simms) when switching from protected mode back to real addressing: https://blogs.msdn.microsoft.c... Windows 2 and XMS could do it multiple times per second, this was early nineties.
No. Amiga used DRAM just like every home computer of that period. You are confusing couple of things. 1 you can reset machine without losing ram contents, this was possible in pretty much every computer at the time. 2 ramdisk for storing files in ram.
SRAM is static, that means you dont need to refresh it = you can power down whole computer leaving only ram voltage rail. This is how storage worked on early portables like portfolio.
Thats the whole point! They are BIGGER than west counterparts and still growing fast. Its a pretty big signal for Chinese, they can care less and less about west. Their well being is no longer linked to the amount of crap west imports from Asia.

no, it was not. 486SX were made using different mask set and had no FPU inside. Im guessing you are to young to ever own real hardware, and read about reenabling fpu on some random website:(
Assuming that this story is correct, and the fact that most with the phone never experience the described problem
what do you think 'class action' means? most users DO experience this problem just like most macbooks with defective nvidia chips died. Those are design defects.
The problem is they are NOT repairing the DESIGN DEFECT (thin bendy non supported PCB results in cracked BGA joints under touch sensing chip). Previous models had metal can (rf shielding) over the BGA chips, this metal can offered reinforcement and provided stiffness. But it added 0.1mm thickness, cant have that, in Iphone 6 Apple replaced metal can with a STICKER.
Cutting traffic means cutting ad revenue. Is this guy retarded? trolling? What is going on? also server cost? Are they running on node.js or something?

why the hell are you self hosting images then? let imgur or other cancer take care of that (and the money from ads they inject because apparently you are incompetent).
make 10 fake uber driver profiles with "scary" pictures, collect from all the fake rides you didnt do, count on cultural fear of ghosts to not get complaints. China is full of entrepreneurs like that.

there are tutorials on chinese social media how to make good money inciting other people to brake traffic laws.
Those repairs DO last because Jessa actually fixes Apples shoddy design by _reinforcing_ touch ic with additional metal shield, you know, the way Apple did it in previous models.
As for economics, would you rather pay another $600 when you can repair your current device for half as much?
this sound nice in theory, but doesnt exist in reality Do you know ANY network with data caps that has a cap close to 2.5TB? Its usually something pathetic like 300GB. This is why people prefer 10MBit with no caps.

nah, I think they will clone some other game this time and call it their own.

In own words of AMD driver developer:
"We don't happen to have the resources to pay someone else to do that for us."

AMD does hardware, but they dont support it with software.

This is Amiga 3000 dram: http://www.ubbcentral.com/stor...
as seen on page 6 of schematic http://www.amigawiki.de/dnl/sc...
here is detailed specs: http://amiga.resource.cx/mod/a...
and here a definition of "static column mode" in case you would somehow think this means SRAM: https://www.jedec.org/standard...
even scan doubler FRAM is based on DRAM
so again, there never was any sram in amigas
ps: I fix computers on a component level since nineties :/

The Amiga used Sram for memory.
no it didnt

its not System76 machine, System76 doesnt make anything (other than the stickers) its CLEVO.
All of the Amiga games were taken down after a ~week.
DisplayPort 1.4 supports DSC, lossless line speed zero latency compression (up to 3:1). I imagine they will reuse that.
