Quote from: gflorez on 15:34, 15 September 21The selection of the CPC ports for MSX hardware.... that is something that was decided by Prodatron, and I don't know from who he took the idea. The target was to fix the upper byte to &FF on the MSX adapter, and so, every &FFXX port access triggers only the lower byte, &XX, to the cartridge.
Quote from: gflorez on 15:34, 15 September 21What I want to say is, the CPC &FFXX range was selected time before making the real adapter, the Amsdap. It was not a chance.
Quote from: gflorez on 15:46, 15 September 21I encourage any development of a V9958 graphics card, it would be great. But... apart from the difference on the ports, the MSX games make an intensive use of libraries on Roms, that would force the conversion coders to add translation Roms on the CPC versions.Another drawback is the use of different memory paginations on CPC and MSX.----About the Coleco, SG1000/SC3000 conversions to MSX, these machines are pre-MSX, so they share more hardware architecture than only the Video chip with the MSX.
Quote from: TotO on 15:54, 15 September 21I know, as I have said that to him by email/PM or at the Revision event.Sorry, the problem is the "chance" word into my sentence. I mean the luck to have a 16-bit I/O port to allow that.Well... The Coleco and SG1000 do not have the MSX ROM or paging system too. The CPC already have the same CPU and sound chip, while them have the same CPU and VDP. Anyway, it does not apply to the existing SymbOS programs.
Quote from: TotO on 11:45, 15 September 21Yes, the V99x8 are already supported by SymbOS that already made existing applications for the OS runable for a CPC with it.
Quote from: Trebmint on 10:55, 15 September 21I'm not sure why people would want to move backwards from a v9990 to v9958. The v9990 is so superior, already exists/works, and does anyone really believe that people will port MSX2 games too the CPC.
Quote from: gflorez on 19:10, 15 September 21Ok, now I understand it. You meant the opportunity to have a spare 256 port range at &FFXX.
Quote from: Edoz(MSX) on 19:29, 15 September 21The v9990 is on the MSX an add- on card. I see it more like the Voodoo card for MSX and now for CPC and ENTERPRISE as well. Running it on different machines would be cool as one release for a game will work on all the machines and no porting is required. Yes there is less software for it but I would hope people will like it and start there own devs for it
Quote from: HAL 6128 on 11:12, 16 September 21Hopefully Trebmint will release his new QUIGS? The IDE so far is quite impressive and interesting and the language easy to understand. I mean, SymbOS is a very attractive environment, also due to it's very good and deep documentation. But you still need to be an machine code professional to create something. QUIGS could be an approach for Non-Professional/Nerds (like me) to program at least something? Would be cool....and after embedding the driver/language support for the V9990 the OPL2 / Adlib sound cards with Pulkomandys Willy adapter or the LambdaSpeak / Midi-Board (with same sound chip) could also be enhanced by Trebmint?
Quote from: Edoz(MSX) on 13:35, 25 September 21Here you can find the new G9K BETA release for Quigs:https://www.msx.org/forum/msx-talk/development/new-symbos-development-quigs-beta-release-with-g9k-support
Quote from: zhulien on 15:03, 04 October 21There seems to be 100s of CPC users here on these forums, but only 17 that want better graphics?
Quote from: ajcasado on 16:03, 04 October 21I'm one of the 17. The problem may be that the price is high and probably also that it will only be supported by SymbOS.For a cheap VGA capable expansion the RPi PICO is a good option. Less than 5€ in Farnell:https://es.farnell.com/raspberry-pi/raspberry-pi-pico/raspberry-pi-32-bits-arm-cortex/dp/3643332?cjevent=f8ea7a5f250b11ec823501d70a18050d&cjdata=MXxZfDB8WXww&CMP=AFC-CJ-ES-1765328&gross_price=true&source=CJSee the yet ready extra libraries : https://github.com/raspberrypi/pico-extras.More functionalities are also implemented in the MCU, as UART(serial port), SPI, I2C, I2S, digital I/O, Analog Input, USB host.It has 30 GPIO pins, so several of the functionalities (audio, VGA, storage, comms and I/O ) referenced above could be used at the same time in a not very complicated expansion board for de CPC.It comes with 2MB of flash to support the desired functionalities code and 264kB of RAM that can be used as VRAM and buffers for I/O, storage and audio.
Quote from: zhulien on 16:48, 04 October 21Something like this interfaced with CPC directly would be a very good CPC gfx card solution because of it's software upgradability. I wonder if @revaldinho could easily modify CPCLink to cater for the Pi Pico?https://picockpit.com/raspberry-pi/raspberry-pi-pico-video-output/
Quote from: revaldinho on 00:01, 05 October 21I like the idea of the Pico as a generic video processor for 8 bit CPUs.
Quote from: revaldinho on 00:01, 05 October 21I haven't see these before, but I like the idea of the Pico as a generic video processor for 8 bit CPUs. This is a totally different direction to the V9990 cards though and might be split off into another thread.
Quote from: Trebmint on 02:47, 05 October 21So you guys want to buy a cheaper graphics card with no software at all, that has yet to be designed, built, and still not that many people will want... hmmm.Software is coming for the v9990 that will make more people want this card
