  1. 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.
  2. @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
  3. 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.
  4. 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
  5. I know have passed 7 years but may be useful for whoever happens to pass by here. 🙄 sm300.pdf
  6. Hi, Yes I think that I can give that in dozens also. 🙂
  7. What the title says. 50 pieces for 500$ including shipping cost, anywhere in the world. Connectors are new, never used! Thank you.
  8. 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
  9. 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.
  10. 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.

  12. 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.
  13. 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!
