Hi all, > - The PDF says: "I/Os are not 5V tolerant". I see a lot of resistors to > handle this. For what it is worth, I have finally resurrected the Vic-20 all-in-one Flash+RAM cartridge project from near death. I have lacked the motivation to finish the software; the hardware is OK since several years ago. Watch this space for a release announcement in the next few weeks. We will release all plans and code for DIY people; I am not going to mass produce it. All parts are 5V. The Am29F032B is probably the largest useable flash memory (4 megabytes, 8 bits wide, 5 volts, TSOP package). The 32k SRAM is a 62256, TSOP. The logic array is a Lattice 1016 in TQFP package. It is definitely too small for emulating a 6502, but there are bigger chips in the family. I have not done the VHDL or touched the mouse-wiggling software for doing that. I merely specified the needed I/O registers to my friend who did it. Marko Message was sent through the cbm-hackers mailing listReceived on 2010-02-03 10:00:22
