I'm slowly working through my VBXE install in an 800XL. I have it installed I think, and when I turn it on, the machine works and I have a picture (just composite for now). Unfortunately, it's in black and white. Where do I start troubleshooting? Here's a pic of the install (large picture!):

How do I do a GRAPHICS 0 command in assembly?

With the three day weekend, I'm starting down the path to learn assembly. It's just a Pong clone, but hey, we have to start somewhere. So far, I've got it to set the background color to black and draw the field: Why can't I get rid of that cursor? Here's my source so far: ; Death By Paddle ; 2015/09/06 org $2000 ;Start of code block COLOR2 = $2c6 CRSINH = $2f0 SAVMSC = $58 SAVMSCLO = $58 SAVMSCHI = $59 XY = $c0 XYLO = $c0 XYHI = $c1 start lda #0 sta color2 ; Set background color to black lda #1 sta crsinh ; Turn off cursor ; Set up player scores lda #16 ldy #5 sta (savmsc),y ; Temporary, print a score of 0 for player one ldy #35 sta (savmsc),y ; Same for player 2 ; Draw playfield drawplayfied lda savmsclo ; Save screen locations adc #112 sta xylo lda savmschi adc #3 sta xyhi ; Calculate location of bottom line (savmsc + 920) lda #82 ; control-w ldy #40 line sta (savmsc),y sta (xy),y iny cpy #80 bcs linedone jmp line linedone vline clc ; Set up to draw the vertical line ldy #0 lda savmsclo adc #99 sta xylo ; in xy store the location of the vertical bar lda savmschi sta xyhi lda #0 ; Loop counter to do it 20 times sta $c2 lda #124 ; Vertical bar - first bar sta (xy),y vlineloop clc lda xylo adc #40 ; Calculate next position sta xylo bcc contline ; If the numbers wrapped, increment hi clc lda xyhi adc #1 sta xyhi contline lda #124 sta (xy),y ; Print the bar character inc $c2 ; Increment loop lda $c2 cmp #20 ; Are we done? bcs vlinedone jmp vlineloop vlinedone jmp *

If this thing is just going to be an emulation machine, count me out. I thought it was going to be a new retro style console...

FYI, on Windows, if you don't have Java and you go to java.com, by default it downloads the 32-bit version. Which means, if you download the 64-bit version of WUDSN, when you try to start Eclipse, it just fails silently. I ended up going to show all downloads (http://java.com/en/download/manual.jsp) and download the 64-bit version.

When this was first announced, I was interested, even at $150. I was hoping for games in the style of mid '90s games and before, like this: Imagine what the game play could be like with the history we have of games. NES Battletoads is an example of a game with brilliant gameplay released when platformers were beginning to be old hat. But now, the focus seems to be moving toward an emulation machine. An itch that is already scratched with the Raspberry Pi, modded Xbox, or computers. The cartridge adapters basically ended native development for the machine. Why would I develop for a machine where my product is going up against tens of thousands of games? It didn't save the 5200, didn't help the Colecovision, or make OS/2 a major player. One idea I had: Stage 1: Put a Pi 2 in the case, wired up to 4 db9 ports on the front. Create a USB based cartridge reader for the machine, allow hot swappable carts. Use an SD slot on the front for game saves. Sell cartridge games in the store. Max of three button controller. Allow anyone to distribute games that play from the SD save game slot. Pare down a Linux based OS so you get SDL and 3D basically for free. Stage 2: (Which people aren't going to like.) Online store for games, download to the SD card that's used for game saves. Allows for $5 games. Stage 3: Have the USB port for WIFI or NIC exposed for LAN play. BOM is less than $75, which means you can reach the price point of $150. Probably a bunch of holes in this plan, but makes sense to me. :-)

Duh, I was reading it as fixing ports on the computer, not joysticks.:-( And the ones I linked to still have the little "ears", but I think they'd probably still work.

Good looking set up.

By reboot do you mean turning it off and back on again, or just using the Incognito cold-restart?

I finally got brave enough to update my Incognito tonight. I started with the PBI BIOS, afterwhich i lost access to the hard drive. I figured as much, so i upgraded the BIOS from a disk image. But even after i upgraded the BIOS and re-enabled the hard drive, I still didn't have access to the hard drive. Hmmmm, after several cold boots to no avail, I had the bright idea of powering the machine off. Which fixed my issue. Did I miss that in the directions somewhere? (wouldn't be the first time

As our school district is going to Chromebooks, it would be awesome to use the A8 as an introduction to programming. Unfortunately, compiling atari800 to Google's portable native client is way above my skills. Has anyone thought about doing this? I guess I could run the DOS version under DOSbox in Chrome, but that seems to be adding another layer for no benefit. :-)

Ill raise you extended color basic:

The 800 blew the ][+ away (full color, four voice sounds, player/missile graphics, LOWERCASE!), but the Apple was a lot more open. Atari didn't really want to share anything about the inner workings. Plus, because of the FCC and Atari insisting that the computers include an RF modulator, meant any sort of slots were off the table. This really hurt Atari trying to compete. I also didn't know at the time that Apple basically didn't let anyone sell the ][ mail order. This increased user satisfaction of the machine because users mostly bought local and had someone there for support. I think this sold a lot of Apple computers. By '83, once the 80 column card and AppleWorks was released, there was really no hope for any other 8-bit computer.

That would be pretty hard to do as president since it would violate the constitution. I guess he could promote an amendment though. :-)

How about asking for transcriptions? :-) I'd be willing to sit down and do at least one.

I may start digging around for RMT tunes and exporting the instruments. :-)

What OS do you run on your computer?

I'd love to contribute something... Do you take submissions? Need a guest from Ohio? :-)

Is there a source for RMT instruments?

In no particular order, these are just the games I play the most: - Klax - Asteroids/Missile Command (I'm surprised this isn't listed as a favorite more often!) - California Games - Battlewheels All great games to pick up and play. Sent from my iPhone using Tapatalk

Put me down for one.

That is a good point!

I think there is some confusion. The micro SD to SD adapter I showed is for the older Raspberry Pi so the SD card doesn't hang out by 1/2", and instead, is flush with the motherboard. Unfortunately, the SD slot in the Ultimate cart is enclosed, which doesn't allow you to use the Pi micro SD adapter. If we could use the Pi micro SD adapter, then the SD card would not be hanging out. :-) It's more of an aesthetic issue at this point, since FJC confirmed the Ultimate Cart does fit in the 800.

I didn't think it would require a redesign of the PCB, just the purchase of a different SD slot (I have no idea what the name of the slot that is soldered onto the board is called). :-)
