The Amiga graphics overlay with a Genlock had a very interesting purpose back in the 90s. There were people out there who would get copies of anime (usually via very expensive laserdiscs or even just tapes copied off of Japanese TV) and would use the Amiga to put fan subtitles on these and then output it to a VCR. It was incredibly manual and tedious work but once you had a master copy you were gold. The US (and in many ways global) anime market owes a lot to those nerdy bootleggers messing with Amigas in their college dorms.

@kaitlyn__L 2 года назад

I knew where this was going from how it started but I’m so happy that 90s VHS anime bootlegs used Amiga for subtitles haha

@milk-it 2 года назад

When I was at uni I used to watch these bootlegs in the '90s at a lecture theater on a Saturday night. These nights always sold out really quick, whereas the nights without the subtitles had empty seats! The humor of Japanese anime blew my mind and left me in hysterics! :-).

The performance of the shared video improves markedly with the addition of (1) fast RAM, and (2) a faster CPU. If you only have chip ram, the bus is contended with Agnus DMA requests coming from the main system, as well as the bridge card.

Great video as always Adrian. I seem to recall, back in the last days I had an Amiga, there was a very hacky monitor driver that I got off Aminet that let you drive a 1084s up to 640x480 with relatively low flicker in WB, but it would cost you like 9 pixels of vertical resolution, plus it would dim the display somewhat. It's what I used up until I sold my 1200 (which I wish I had back :/ ).

The Amiga 3000 had a scan doubler built in so you could run a standard VGA monitor. It had a separate VGA port and a enable / disable switch. When you connected a VGA monitor to the Amiga 3000 you would set the switch to enable and it automatically scan doubled the slower signal to a signal compatible with VGA monitors

@judgegroovyman 2 года назад

Well the Genlock feature was used extensively in video production. There were lots of animation studios doing animation on Amigas. The most famous one today is of course Dingo Pictures. At least in Germany getting a 15kHz CRT is incredibly simple, people just throw those out and any newer one will have an RGB input. The only problem, however, is that those are mostly low resolution ones.

I'm guessing the mode I used for Workbench must be AGA only, it's called DBLPAL and allows for progressive scan at 676x540(this, of course, with gratuitous use of overscan) at 50Hz by the RGB out. I currently use it plugged into a modern multi input LED TV via VGA cable, which can autodetect what I'm running and switch modes automatically. Back in the day I had to have dual screens, one a regular TV hooked up via RF if I wanted to play a game in regular PAL and the second a VGA monitor for using Workbench and productivity stuff.

@ClearComplexity 2 года назад

The most expensive part about putting one of these together would probably be the components. It's a lot more efficient to order (at least the basic stuff) in bulk, when I build keyboards I get enough parts to put together most of 4 or 5 for the price of ~2. Then again I only do that because it cost the same to order 5 pcb's as 1 on most places too, cheaper in bulk all around. If you're good at soldering (this project looks fairly straight forward, the smaller SMD stuff can take practice) a person could probably put together a few of them at the same time and sell the extras to easily cover the RasPi and parts.

@nilswegner2881 2 года назад

The Chip that does the memory Management is called Agnus in OCS amigas Like the 2000 and 500 and the Upgrade you have on that 2000 introduces an ECS memory Controller that's called fat Agnus that would normally only be found on an A3000, an A500 plus or an A600. Although there are some exceptions Like in everything that has to do with Commodore...

@NozomuYume 2 года назад

Not quite accurate. Agnus was the ICS/OCS DIP package version of the Agnus. Fat Agnus was the OCS PLCC package version of the same chip introduced in the A500/A2000. It was functionally the same as Agnus, it was just in a square package (hence it looking "fat"). Later ECS versions of Agnus didn't really have a proper name but were often called "Fatter Agnus", "Obese Agnus" (for the 2M version), or "Super Agnus" colloquially. The ECS Agnus was mostly identical to classic Fat Agnus, but had the ability to access more memory, allowed arbitrary vertical refresh rates, and allowed larger blitter operations (the blitter didn't work any faster, but you could blit more with just one command -- nothing really used this feature until AGA, but you could theoretically reduce how often the CPU had to talk to the blitter and work in fastmem or cache instead).
