@foft I have no objection to this. Go right ahead with the poll. I look forward to reading it discreetly.. as an observer! 🙂

Found on ebay. 🙂

Necro-bump I got in my hands a Atari 130XE for repair. It had a defective oscillator. In my case also I not seen the 4 large bars on bottom of memory test screen, in the self test mode. I tried what the post Nr 6 says (Rybags) with success. Then I tried to load T34-The Battle game with success also. Specific after the intro during loading a message "extra memory detected and used" appear and the rest of game load normally. Menu appear and after I choose the play option game start normally. Very strange. 🤔 PAL 130XE BOARD CO70067 REV-B ROM CO61598B-01 BASIC CO24947A MMU CO61618-20 EMMU CO25953-20

I would like to buy the "reset" and "break" keys for Mitsumi XE series keyboard. If someone have some as spares please contact me. Thank you.

@Rom Hunter I did it! I tried those also in Stella emulator. Stella recognized and named these except of two. 16 roms x 4KB.rar 32 roms x 2 KB.rar

Thowing a second look in pcb, this cartridge support 32 games of 2KB, and 16 games of 4KB. Whenever the switch marked as A16 goes high it return the control of the A11 of mask rom to Atari. So this can handle the last 16 games as 4KB roms. So we speak for 48 games total.

Multi game cartridge for the Atari 2600. Is marked in its upper decal as “Multi-Games” and it have 64 games. It have 6 switches and a 1Mbit mask rom of 28 pins. Below attached the rom content. A2600 Multi Games DUKE chk 8D1E.BIN

I know have passed 7 years but may be useful for whoever happens to pass by here. 🙄 sm300.pdf

Hi, Yes I think that I can give that in dozens also. 🙂

bump

Very vintage feeling!❤️

What the title says. 50 pieces for 500$ including shipping cost, anywhere in the world. Connectors are new, never used! Thank you.

I need this specific Sega custom ic, new or used in working state. Thanks. https://wiki.megadrive.org/index.php?title=File:315-5364.png

I haven't some fancy psu like usb etc, just the original by Atari. The only thing which changed is the monitor. I have a Philips tv/monitor with a native 640x480 IPS panel. But I think is incompatible with VBXE.

The same here on my Atari 1200XL installation! 🥺 Very weird! In the past it worked right! Now it have the right colors but a very snowy screen! I have try the sync from composite video either direct from cd4050, but with the same exact result! I have right clear screen from the stock composite video, if I remove the VBXE and restore the removed components... This is a PAL 1200XL using the GTIA PAL adapter form Dropcheck.

Ok lets say some things about it. Is a board for the third memory slot of A800. My intention and its main operation, is to run SDX with RTC and to handle an external cartridge above of this like the standalone SDX cartridge. As usuall, without the need to modify your computer. At the same time it must provide the lost 16K memory of the third memory slot. This memory will be needed for the users that have only a simple Axlon memory board (for example 512k) in the middle slot. Will not needed for the owners of GPB, or those with some Axlon boards who provide also the rest of main memory. The setup of this board will be available from a menu, like this in the GPB. I'm also thinking about what I could do with the remaining 256KB of the flash rom, like putting some OSS tools in there, selectable via Patrick's menu. We'll see.. Now as for the external cartridge, it will be work via an small adapter which will snap into the left cartridge slot of the A800. In this someone will be able to clip the external cartridge. For the most skilled user who can disassemble his Atari, and place a small adapter on it without naturally solder cables etc., the profit will be to be able to use naturally, without adapters, the left cartridge of his Atari as is. As I said these are my intentions, but I will know better after the sample pcbs arrive here and work with these.

Hi Larry, 1. At this time I work on another project complementary to this one. I have already design the pcb and prepare the logic but I still have a way to go.. But if for example 10 more interested members would be found, I think I could arrange one more batch. 2. Why I think that this must be answered by Patrick? 3. Yes this menu is an excellent work from Patrick. I like it also very much!

I bet that if Mr.Atari share his MyBIOS source and notes, you would take it to another level! 🙂

Wow Patrick excellent work! And what speed among the changes! 😀

Maybe I didn't understand well. 🙄 So to understand, how many external ram I need to have in my Atari computer so the uflash it be able to burn the whole 512K version of SDX, in Lenore's super SDX cartridge?

Hi John. I am not programmer so just I wonder if someone write in the flash rom(AM29F040) the SDX 512K version via a external programmer, it could work correctly after in this super cart? Panos

Question! Have anyone find the schematic diagram of PAL CPU board for Atari 800 anywhere? In every service manual that have in my possession, only the NTSC CPU board is available.

👍+1 I support your cartridge shells 100 + 1% and I propose to the new and existing hardware inventors for Atari 8 bit, to use it! Personally thank you, who was take the risk and the cost to manufacture these in quantities.
