Re: Apollo Team announces developing of Vampire standalone version to run as AMIGA and ATARI ST

The design which will be compatible with more original software developed 20 years ago will be more successful. Gimmicks like video playback won't change anything. Everyone has at least smartphone which can play the video with less hassle than any new CPU in Amiga/Atari. Look at New Genaration Amiga...

Re: Apollo Team announces developing of Vampire standalone version to run as AMIGA and ATARI ST

A lot of low-power devices use special macro-commands or HW modules to playback audio and video. Apollo didn't invent anything new here. But still, it's useless. There is no market for their CPU today. It's fully occupied by modern devices.

Re: MiST VGA upscaling experiments

I use Avermedia U3 capture with HDCP patch :) The problem with VGA is because it's not VGA actually.
De-interlacer in LKV362A is pretty good. Better than in other similar by price scalers.

Re: Apollo Team announces developing of Vampire standalone version to run as AMIGA and ATARI ST

Faster and cheaper ARM SoCs are readily available, and most people here seem to lack the imagination to see where such a fast clone could be successful. So that leaves the retro stuff. I think we all agree that the really fast 680x0 clone will not help the retro games/demos department. Which leaves...

Re: (Poll) Most wanted new MIST cores: FINAL ROUND

I think most of my USSR retro cores won't ever appear in such poll, but it doesn't matter since it's fun to make them.
So, don't mind if you are working on core not listed here.

There is another problem - they've added new instructions into 68K which will confuse and may break apps/games/demos expecting original behavior.

Re: Apollo Team announces developing of Vampire standalone version to run as AMIGA and ATARI ST

There is one of big problems: once you use this board (add-on or standalone) you loose original 68K CPU. So, if you install it into A600, then your only choice is this emulated CPU. While developing cores for MiST, almost every retro system i've touched has been depend on exact CPU and chips cycles....

PDIP case and up to 1.7MHz clock. Could be 10MHz SPI, but it's not enough pins on MIDI header.

Re: Extra MIST I/O?

If i remember correct, there is I2C->parallel converters. Need more exploration of availability of such converters. So, if they can work on high speed (through MIDI 4-pin header), then we can have more GPIO for retro. Obviously these converters should support two-way communication. From other side, ...

Re: Apollo Team announces developing of Vampire standalone version to run as AMIGA and ATARI ST

What is the point in a cycle exact 060? Is there a single piece of software out there that needs that? I'm talking about Amiga where some software for 060 do exist. I don't thing Atari will be supported in the near future, especially with their style of coding under the blanket. Any turbo modes are...

Re: Apollo Team announces developing of Vampire standalone version to run as AMIGA and ATARI ST

No, i wanna say, this project will have very little demand comparing to modern boards. For example Raspberry Pi has much bigger demand. I didn't ask them to put a lot of effort to develop the core which basically won't be used at the level they expect. There is open source 68K core which could be ad...

Very questionable "advantage".
Owners of real retro computers (C64, Amiga) are adding HDMI/DVI output, while you cripple the video intentionally on capable hardware.

C64 has licensing issue - this is the main "hand brake" in its development. You need to complain to original author of C64 core.

Re: ZX-UNO Spectrum FPGA

The biggest downside is the smaller FPGA which rules out some cores there a several big downsides: 1) small FPGA (it's not only smaller by LE, but also smaller FPGA RAM which is cruicial for some implementations). 2) small RAM chip. Only 512kb. The usage of RAM is not only for emulated systems, but...

Correct targeting of your product is also big part of success. What is audience of Amiga and Atari computers today? People of 40+. And more time pass, older audience will be. Only small fraction of younger ppl are interesting in Amiga/Atari. And they are not bound by nostalgia when you could see the...

As far as i know, Apollo team go closed source because they want their investor give the money for ASIC version. But why they don't want to use Kickstarter? They've said they need around 250K which can be made through Kickstarter. ASIC won't allow you to change the core once it's in silicon. It mean...

Re: MiST VGA upscaling experiments

another opensource scaler: http://www.staringlizard.com/2015/09/14/amiv-3/
This looks more capable than OSSC since it has 1MB frame buffer (although it's not enough, IMHO). Unfortunately, it also misses audio injecting part.

Re: MiST VGA upscaling experiments

Just ordered a LKV362A. It does seem like the most cost-effective solution. Cheaper SCART upscalers are bad; I picked one to try and while it works in general, it has a lot of interlacing and lag. At least it also works with Composite / SVideo; so I have some use for it. Don't you have XRGBMini alr...
