Woow! This is a great thing! Big respect for the amount of work that has been inserted into this project.

Hi, I'm thinking about this kind of software. Because current version of Slight-SID supports two SID chips, line in, and line out connectors, You can connect external audio signal and mix-it with SID voices, or use SID filters (LP,HP,BP) to filter the external audio signal. That can be of course POKEY audio. So if You have stereo POKEY inside Your Atari, than you can connect it together and have 4 channels of POKEY sound mixed with 3 channel SID sound at left audio channel, and the same is possible on right audio channel. Line IN and Line OUT connectors is 3.5mm standard audio mini-jacks.

Hi! Sorry for silence from my side. The project is not dead, but I have some problem with free time. I'm very busy with projects at work. For projects such as "Slight-SID", I spend my free time, and I will try as soon as possible to comprehend it all. But sometimes the prose of life leaves no time for hobbies. with greetings Sebastian

Hi Foft! At first I want to thank You for all great work that You do with this project! This is awesome! Now I have one question I have the Altera DE2 board ( http://www.altera.com/education/univ/materials/boards/de2/unv-de2-board.html ) It is possible to "recompile" Your project to work with this board? I'm curious that I can use this hardware (DE2) or must buy the DE1 version or wait for the final product? with greetings Sebastian

Thank You very Much! That photo is good quality and hi-resolution! This is enough After repair I will post the photos of my version of ViF! with greetings Seban

-- please delete -- ps) doubled post ;/

I would like Only family and work are cause that I does not have as much free time as I would want to have with greetings Seban

Hi! I have that piece of hardware too, unfortunately it's broken ;/ Maybe You can help me to fix my unit, after all those years? A long time ago I removed the broken chip and an IC socket was inserted, but at that time I could not get the new IC, so the interface lay in a box dozen of years. The broken chip was lost, and now I can not remember its symbol. Can you help me and take a picture of the interface board? If I remember correctly, that chip was a fast parallel 8-bit counter located in "top-left" area of the PCB, near the CD4046 CMOS PLL. As a curiosity in the "story of the past", I might add that this Video-Interface was used at various demos from us (Slight and Code3) , at this moment I remember that it was for sure: Digital Trash/Slight ( http://atari.fandal.cz/detail.php?files_id=304 ) Bitter Reality/Slight (http://pouet.net/prod.php?which=9749 ) Overmind/Slight ( http://pouet.net/prod.php?which=9748 ) Saturday Demo / Code3 ( http://atari.fandal.cz/detail.php?files_id=970 ) Some screens in each production was captured with use of this device. Long time ago I wrote additional software for this interface, it was called Multi-VIF, and I will try to find it on my old 5.25" Atari disks Maybe Miker remember more demos/intros where we used ViF. with greetings Seban/Slight

Hi! This hardware is not fake... here you have the real hardware: and here more videos: https://www.youtube.com/user/psu65816/videos you can see some software runing at turbo speed (14MHz)

Hi! I never thought I'd see the day, in which the 8-bit Atari will be able to play high-quality video! Fantastic Idea and great work Avery! greetings Seban

Awesome! nice trick with VSCROLL to avoid ANTIC screen-DMA access :]

Great production for VBXE! Thanks for this! Great music, nice graphics and cool effects for VBXE!

Hi Hias! Thanks for that information. But there is only one small problem, those type of connector must be mounted on top of the PCB, if I want to mount it on the edge of PCB there will be small mechanical problem (the distance between the rows of pins is about 3.58mm). I'm right? I buy some samples from mouser and check for possibility of mounting it on edge of PCB. greetings Sebastian

Hi All! The detection of Slight-SID cartridge is possible. Due to the passthru, this is possible but there are two problems... a) additional cost (connector, housing adjustment) b) the cartridge edge connector for making passthru is not easily available with greetings Sebastian

Hi! The second version of Slight-SID will have a line-in You can connect any external signal, such as audio-out of POKEY. You can use internal SID filters for external audio processing. In fact, the first version was a substitute for line-in, but it was too poorly protected (ESD), so I decided not to connect the first prototype. with greetings Sebastian

Hi! I'm the Seban/Slight (Sebastian Igielski) and I'm the author of the first version of SID cartridge for 8-bit Atari. The first several pieces was done as a prototype version, and all worked fine. But due to high cost of components there will be second generation of this project. It will be completely redesigned to reduce total cost of BoM. The first old version was based on PIC18 MCU and some external logic to handle two asynchronous clocks (SID clock and Atari clock). As mentioned Candle, at this moment I have about of 50pcs of original SID8580 chips, and that can be used do make commercial version of Slight SID Cartridge. So, if you would be interested in this product, I can seriously think about the production of more Slight-SID cartridges. The first prototype version look like this: with greetings Sebastian

Hi Heaven! You are right, there are no to much productions that use own SIO routines or IRQ loader. I don't have much free time, but if I find some free time, I try to describe how to do own SIO routines or how to write IRQ loader. The additional problem is my fatal "english" I don't write or speak very often in this language So sorry for any mistakes big greetz Heaven! Seban/SLIGHT

Hi! You need two things: 1) own SIO routines 2) ultra fast music player While POKEY do the serial transmission only two channels (merged in one 16 bit channel, to give 16-bit precise baud rate generator) are used. Next two channels is free for your use. The system SIO routines is not prepared to work correctly with any music player. But after some changes it is possible to adopt it to co-operation with simple and fast music player. But in my opinion the best solution is... write own SIO routines. How it works in real world, You can see our old production Overmind. This trackmo have own IRQ loader, and plays music all the time (while loading next parts, music player plays only 2-channel music) with greetings Seban/SLIGHT

Hi! If I correctly understand your problem, solutions is very simple, and the file structure must be as follows: <intro data segments> <init address> ($2e2,$2e3) <game data segments> <run address> ($2e0,$2e1) If you have two XEX files: intro and game, the intro source must have init segment, for example you can do in this way: ; intro code org $a000 init lda #$00 sta $22f ... ... intro code here ... ... rts; here is end of intro, rerurn to the loader. org $2e2 dta a(init) org $2000 ; game code run lda #$00 sta $22f ... ... ... game code here org $2e0 dta a(run) But remember that your intro code must restore all modified interrupt vectors, and turn off the sound generators (the simple way is put zero to $d200-$d20f locations), before do the RTS opcode. with greetings Seban/SLIGHT

Hi Fandal! Great piece of work! I have some questions about SuperCharcher. Now probably You know everything about supercharger can you tell us more details about it? (e.g. register map, commands, math). Can You tell us what kind of calculations done by the hardware? Looking at game code, we can see that the game code puts some values at $d5xx page, wait some time (nop,nop,nop), and read the result from $d5xx. Please tell us more I'm very curious about that. whooops... i have noticed that HiassofT described registers and commands of supercharger at post #14 in this thread so my question in that case does not have any sense sorry with greetings Seban/Slight

Hi! Some time ago on Atari Area forums we talk about it. In that time You have connected the second POKEY IRQ pin. Did you disconnect this PIN? It should not be connected. The IRQ pin of second POKEY must be not connected to anywhere. We talked about it here: http://atariarea.krap.pl/forum/viewtopic.php?id=4233 with greetings Sebastian Igielski (a.k.a. Seban/SLIGHT)
