Hi, There is no way that it could be ported to the MiST. Aside from the FPGA capacity, the main issue would be the 64-bit data bus. The board I used for this purpose is a decade old Stratix-II evaluation board found by chance on eBay, coupled to a custom daughter board for VGA output. The main advantage of this board is that it features a 32-bit SSRAM, which was convenient. Starting from the original netlists guarantee that Tom and Jerry chips are 100% exact. However, the remaining parts may not be so accurate. But it should be quite easy to fix, especially by someone that knows the machine, like SCPCD. Now, it would be nice to find a board that features all the required parts (maybe a DSP-oriented FPGA board), and cross fingers for the price tag. Regards

My bad. In fact I've added a rough SD-card interface and selector for the Chameleon-64 hardware, but if it is of some interest, I could add them to the DE1 version. There will still remain the issue of joystick interface, though. Nice work by the way, I've considered at one time working on Atari 8bit series of computers, but it seems useless now

Well, before adding support for other hardware, I still need to do the "basics", as connecting a joystick or adding sound output Also, as it is a bare port of the netlists, it currently runs only on high-end FPGAs. One of my primary goals would be to trim down the reqirements, by removing/enhancing existing logic so it would run on a Cyclone III for instance.

The blank band comes from my scandoubler (for VGA output) miscalculations of blanking periods About sound, joystick, etc. I still need to connect Jerry's I/Os to something... It shouldn't be too hard to do

Don't worry, bugs are still there, I may have added a few myself Some changes have been made to the netlist, most of them were done to cope with the weakness of my compiler/translator. I had to change a bit the memory controller to handle a "RAM ready" signal, but it may be unnecessary now (I had to "map" the 64-bit DRAM access logic of the original design to the 32-bit SSRAM available on the FPGA board).

Well I'm not that much into Intellivision, I just made a proof-of-concept cartridge emulation with a FPGA. However, I'm planning to do it again, using a fast MCU this time. Very nice! If you don't mind sharing your work, I think I could help on some of these tasks. BTW, did you know this guy's project ? I'm contacting you right now

Someday I'll finish my 2600 VHDL project. In fact, I might just release the source code when Wanga comes out!

I'm playing with FPGAs too, and I would be interested by what you've done so far with the 2600. I've emulated some old (obscure) computers myself (the latest one being the Oric-1). Have a look at my website, there is some information about my projects.

You can also use EEPROMs instead of EPROMs (no need for an eraser in this case). Here is what I did to use a 28C64 EEPROM on a Pixels Past 2K/4K PCB : Works fine on a 7800 I own, haven't tested it on a 2600 though.

Nice to see the site back online. On another note, the store is "down for maintenance". Is it related to this issue or not ? Does anyone know when it will be back again ?

Go to Options, Input Settings, in the Emul. Events tab. Select the "Toggle debugger mode" item, click on "Erase", then "Map" and press the key you want to use to enter debugger mode.
