Guest sjdavies Posted February 8, 2012 Report Share Posted February 8, 2012 Hi All, am new to Papilio, bought a 250K but it's still in the anti-static bag. The arcade megawing 1.1 turned up today. Have been working with a Digilent S3 starter board and apple2fpga. Have got a working Apple][ with SD ram disk. I would like to be able to use the Papilio & megawing as a dedicated retrocomputer (apple][, C64, Vic20 etc.) AND for retrogaming (eg. galaxians, space invaders etc.). I would like to be able to do all of these functions standalone i.e. without reconfiguring via USB/JTAG. Moving to the Spartan 6 sounds fantastic, as does the provision of external RAM. I'd also like to propose some additional features. Consider other configuration options besides JTAG/single flash. Possibly make M0/1/2 strapable (if they exist on S6). My thinking here is to allow some sort of menu system to select one of many game images present on an SD card i.e. to have selectable MAME ROMS to play. Consider adding an AVR or external logic to act as bootloader for the FPGA. Another thread has suggested something similar. From the viewpoint of retrocomputing, a second SD card is desirable. Allow it to be configured as the floppy/hard drive for the retrocomputer. Configure the FPGA from the first SD, allow the retrocomputer to boot from the second. The megawing 1.1 has loads of empty board space, why not make a 1.2 and add some solder pads for user config and/or extend the pins coming up from underneath? Papilio One and the arcade wing are interesting but after buying into the concept it really doesn't offer enough flexibility to do what I want to do. Disclaimer: what I want is not necessarily what other peeps want to do . Papilio seems to have a lot in common with http://www.fpgaarcade.com/. I intend my comments to be taken as constructive criticism. My personal ideal is to have a standalone box where I can select arcade games AND apple2/C64 games stored on SD cards. What do you think?
