I have 1 fully operational colecovision ... and another that operates but will only run 32k cartridges. If I put in the Ultimate multicart or a megarom cart it will not run. Multicart gets the splash screen and then goes blank. It seems to have problems with the bank switching. Just wondering if anyone has a suggestion .. other than blowing into the cartridge slot. Attached is pictures( more gold & yellow) of the coleco mother boards top & bottom from the system that will only run 32k carts And yes, it has a modified power switch but that was only installed last night and the problem predates it. And here is the fully working system ( more green & silver) of the coleco mother boards top & bottom from the system that will run all cartridges carts
Hi all, I have created the following post yesterday: Someone just told me that I should have created it in this subforum. I don't want to duplicate the post but I have also not found how to move the post here. Any suggestions? Also, if you can comment on the bankswitch schemes you currently use in your programs and any experience you can share on how to implement a bankswitch controller on a 8bit Microchip PIC will be much appreciated. Cheers!
Hi All, I thought I'd post to announce my new hardware project - I'm building an SD-card based Multicart. https://youtu.be/PjkCTXqirv8 Although its far from being finished, it already shows the available ROMs/CARs on the SD card on an Atari menu, and will then reboot to the selected cartridge. At the moment it only supports 8k ROMS and 8-mbit Atarimax ROMs, with bankswitching etc, but I plan to support all cartridge types soon. Adding a new ROM is simply a case of copying a new file to the SD card - no more flashing ATRs etc. Not sure if there's any other available hardware that currently does this? I don't have an SIDE or MyIDE. The hardware is a Altera Max 10 eval board, with my 3.3v cartridge breakout board attaching it to the atari. There's an external 1 megabyte SRAM which cartridges are copied to. Initially the atari boots to a small 8k boot ROM which is stored in dual port memory on the FPGA. The FPGA is also running a soft-cpu to copy files from SD card to SRAM. I'm planning to make a PCB for this next, with the aim of fitting inside a standard cartridge case. Never done an FPGA board before, so that may take me some time. The boot ROM is also far from finished - I'm having to learn 6502 from scratch. There are some other possibilities for this too - the same cartridge could be re-programmed e.g. as an atari co-processor/accelerator board. I'm planning to leave a JTAG/USB Blaster header on the board to make this easy. Robin
Hello, new member here: I just bought this game... ...Off eBay, and I thought I'd attempt to get a value/rarity estimate on it. Was $20 too much for this? It's similar to the multitude of PAL multi-carts listed on the rarity guide, but this exact design (a space program going horribly wrong over a field of box-art; four dip switches on the front) isn't listed. (Though the exact same image was shown on the box of another 2600 multi on eBay that recently ended-though the cartridge itself did not have the same image on it as its box.) I'd asked on Digital Press first, but since their forum is about as active as a sloth I'm asking here as well.
