Time travel?

​@@jacobmckenna8661Patreons get early release videos. KZfaq displays the video publishing date when it went public, not when it was available for people with the secret link.

I believe that method is called "sync on green" right?

Those computers used RGB 5-5-5 with 1 bit of padding in 16 bit (“thousands of colors”) modes. However, other standards and video hardware could use 5-6-5. On PC, ATi mach cards even offered both 5-5-5 and 5-6-5 sets of video modes. Might look like an oddity today, but at the time something captured by a camera or rendered that was not a high contrast full range picture, something that had large areas of similar tint, most often resulted in puke colors and banding when seen in HiColor mode. That extra color bit could be an improvement in those cases. Note that system interface and website graphics shown in the video stick to 256 color images, the default of that era, and thus don't change noticeably from switching to 16 bit mode and back. On the other hand, in software each color channel in QuckDraw is represented by a 16 bit fixed point value, which is way too future-proof. Maybe their intent was to make everyone handle color conversions in the most correct way possible.

Yup! Very much a trial & error whilst crossing your fingers and being at it MUCH longer than expected, activity. I rarely do it anymore, but I used to a lot a while back (1995-2009). I was a teenager, then poor....then had a kid, making ME even poorer(harder to justify spending money on stuff like gaming PC hardware). Luckily, I enjoy trying to make older hardware run as well as it possibly can since for a long time I had not choice during the long periods of time between builds. Especially since when I did build, I could usually only afford hardware that was just made "last gen" giving it less longevity at least for gaming. In 2005-06 as PCIE GPUs were coming out, I was looking to upgrade, but didn't have enough money available (with kid on the way) for a full build. I ended up going for the best CPU my mobo would take (Athlon 64) cheap used, and the best AGP GPU I could (ATI x850 ALLinWonder), and some parts for a liquid cooling loop. I cooled the CPU and the GPU via Thermaltake water blocks and an old dirt bike radiator inside an old mini freezer. I spent about 3 months messing around with settings on the hardware and cooling system to get it stable. Once I did, I was able to play Oblivion with some pretty nice settings. Not as well as I could have with a PCIE card and newer CPU. I ended up having to dig up my key gen for XP Pro so I could use more RAM, too. That was actually the last upgrade for me until like 2009ish. Unfortunately I fell for Nvidia Marketing. It was when they released their first card series with DX10. I always used ATI (AMD) after a bad Nvidia experience early on. Unfortunately having had such a long time between builds, I was worried I would shoot myself in the foot if I didn't get the DX10 card even though the AMD version was a much better value(some things don't change). I gave in and quickly regretted it. The card was a glitchy mess way overpriced. The worst thing about it all was that when I finally upgraded to my first full new build in a while years later, there were still hardly ANY games (at least ones worth playing) that even used DX10. I learned a lot from all of that at least. Mainly that it is almost never worth adopting the newest hardware right away since almost nothing will make use of it until it has been on the market long enough for devs to take advantage of it. Also, it often changed before then too! By the time DX10 games were regularly released, DX10 was quite different than the version that was first released by Nvidia. That happened again with my RX480 later on with DX12. However, I didn't buy it because it was an early DX12 card and it just happend to be a feature. Nvidia was really hyping I though. I think AMD prob only included it to avoid customers making that choice I did with the DX10 card. That was a great card though and the driver updates actually had it working quite well with DX12 even as recently as a 19 months or so. Back to overclocking, I replaced the rx480 with a Sapphire 6900XT Toxic (extreme edition) with integrated AIO liquid cooling and a 360mm(3 fan) radiator. Although, I didn't OC it, it was already done for me. It is prob the best GPU from that run except maybe the 6950xt version of that card which was not available when I got mine for an awesome price(at the time). It's a fantastic card! Especially with my 5800x3D. Anyway, that concludes this overlooking story. Overclocking has its place, but unless it's done for fun(to see if you can) there really isn't much incentive now days. Most CPUs come pushed about as far as they can be while remaining stable. Plus most CPUs on the market are already overkill for most applications unless you get a crazy expensive card like a 4090 or something and are trying to play at 4k with over 60 FPS full blast. Still, once you buy what you would need to OC a new chip enough to be worth it, you might as well just buy the better CPU. Heck, my "last Gen" AM4, 5800x3D ties or beats the 13k & 14k(aka 13k) intels that are nearly 3x the price in gaming. Ok now I'm done! $ end /rambling commrant\:

I'm pretty sure there's an equation for this I forgot what it's called but it's related to the mandelbrot set

@@hp4985yeah, there would be but you would have to know things you likely wont have the data for. Actually, what likely causes instability is by raising the voltage will change the bias of the transistors and if the bias gets to saturation then… ya know. And speed will have to do with capacitance and inductance. Too fast and the signal will become a blur. You also have diode breakdown voltage. So if you have a formula for all this, good on ya. Lol but its not worth much except for having some fun with math. You may as well experiment. Now it could be useful if ur chip is super super expensive.

Depending on how you are overclocking this can be due to various bus or clock straps/ratios - they'll often have a certain number of multipliers relative to the CPU frequency and as the CPU frequency increases after a bit they reset back to the lowest ratio then start increasing again (grossly simplified).

100% evergreen comment there!

Like a decimal floating point format.

10×10¹ Ω ;)

i know for a fact they would do that with a powerpc upgrade too (ie a quadra 810 would become a powerpc 810)

They are so cheap now as well ... so just setup some ports for 10/half duplex and you won't ever have issues with the ancient machines.

One to remember, at 10M half-duplex collisions will be normal on that wire, just not excessive ones. It’ll actually be doing CSMAD as designed. To a point.

You can also avoid having to configure anything for your older systems by plugging them into an unmanaged NETGEAR GS305v3 switch before going to your regular router. It works perfectly well with older Macs and PCs with 10Mbps half-duplex Ethernet as well as strange early 100 MBps cards while segregating them and their quirkiness from the rest of your LAN.

The other reason to use managed switches, or at least partially managed smart switches (which can be cheaper), is to use VLANs to separate out these older machines with vulnerabilities and odd behavior from the rest of the modern computers on a home network. I also put an older B or G level router on the same VLAN so it's isolated given the known vulnerabilities in these older routers that might only have WEP or WPA1. This is one part of my strategy to manage older machines, including running Win98/XP/7/etc for safety.

​@@Cherijo78Just a heads up, most of those cheap managed switches don't support VLAN, or at least not in hardware. Probably wouldn't matter for these old machines, but I'd pop for a Mikrotik hEX or hAP ac2 for full manged and VLAN hardware support. As a bonus, something like the hAP ac2 can even be used as a switch to wireless bridge so you can connect these machines to a WiFi network.

That doesn't make any sense. Swapping resistors wouldn't change the clock frequency. Unless it's using an RC oscillator which I strongly doubt.

For me, a crumpet is a pancake-like food usually eaten with butter&jam... can you elaborate on what you used?

@@rivimey it’s an autocorrect error. Should have been “crimpers”. We used some creative methods to get things done with our limited budget but I don’t think we ever resorted to baked goods for anything other than our morale.

gives new meaning to the song push it to the limit🤣🤣🤣

Fun fact, it also ended up on IBM's LAN Adapter/A Microchannel Ethernet adapter.

It can be done, but depends on so many factors that it'll normally be better to treat it as program-specific rather than to treat it as a generic subject. For example, slightly more adventurous ISA bus hardware+driver combos could transfer most or all of their data movement to DMA channels, but less adventurous examples might implement all of that in software, leading to massive performance differences...

Ah well, oops. Thanks for pointing it out sadly no way to fix it now. (I'd have to take the video down)

@@adriansdigitalbasement all good, great video. You have inspired me to try doing some similar mods on my C610! 🙌

Ive got an apple workgroup servre 60 and it makes the chime but then it does the crash up sound and I do not know what is wrong is there any thing you can help me to do to save it?@@adriansdigitalbasement

I’m open for nearly any Mac architecture. I only have Intel and PPC right now, but I want to get a 68k machine. MX is too expensive right now.

Ah that's good -- I hadn't heard of that trick before. Nice! Yeah that Ram Tester is a rare thing to have -- so 99.9999% of people won't have the luxury of using it.
