Re: Jr Cartridge blank for eprom

fantastic work! We should give the bootloader to one of those demo scene guys who can put an entire chess game into a boot sector to see if they can optimize it further to make the menu pretty but still fit. :) After I'll get experience how to write for ROM using C/C++ then I'll do better compressi...

Re: Jr Cartridge blank for eprom

It would be oddly cool to take this project: http://www.brutman.com/forums/viewtopic.php?f=3&t=364 where I converted a bunch of cartridge games to run off a floppy disk and convert it back to running entirely off cartridge again! I don't quite recall how much storage space all of the games requ...

Re: Jr Cartridge blank for eprom

makes sense then why colorpaint when launched directly from my "carts on floppy" disk fails to load. No DOS == no worky. If I ever go back into that project for another update I will remove colorpaint completely. or you can make your disk DOS-bootable and call your menu program from AUTOE...

Re: Jr Cartridge Ethernet {IDEA}

How about VGA output vis-à-vis the TRS80 M1 MISE http://bartlettlabs.com/MISE/index.html (which uses a WIZ830MJ)? Mike I think it's too much (especially for the price $330 - you can buy brand new computer for that : ) I want to keep price below $100 (preferably around $50, but not for the 1st batch)
