Cp-mega88 - CP/M running on AVR ATmega88 with i8080 emulation

  •        0

What is this?This is an i8080 emulator running on ATmega88, and on which CP/M can run. Specificationto be written Software TestYou can try to run CP/M on POSIX environment. Build% hg clone https://cp-mega88.googlecode.com/hg/ cp-mega88% cd cp-mega88% make -f Makefile.posixBoot CP/MFor booting, you need a CP/M disk image named 'sdcard.img' in current directory. i8080 I/O configuration of CP/Mega88 is compatible with z80pack. So you can use the image for z80pack (see following external resources section). % tar zxvf z80pack-1.17.tgz% ln -s z80pack-1.17/cpmsim/disks/library/cpm2-1.dsk sdcard.img% ./cpmega88booting CP/Mega88 done.memory write test: 65535/65535memory address test: 65535/65535SDC: okFAT: error(02)EEPROM: initCP/Mega88>bA>_In addition to CP/M raw disk images, you can use FAT formated SD CARD images which include CP/M disk images. In that case, you should mount CP/M disk images before the boot command. % ./cpmega88booting CP/Mega88 done.memory write test: 65535/65535memory address test: 65535/65535SDC: okFAT: FAT16EEPROM: loadCP/Mega88>ls -rw- DISK1.IMGCP/Mega88>m DISK1.IMGA: DISK1.IMG okCP/Mega88>bA>_Monitor CommandsCP/Mega88>helpmonitor commands r : reset b : boot CP/M 2.2 wp : file system write protection a : auto boot mr : memory read from mw , : memory write to so : sdcard open sd : sdcard dump block buffer sf : sdcard fetch block ss : sdcard store block ls : file listing cd : change directory m : mount image disk vt : vt100 compatible modeHardware Testto be written Schematic Internal Resourcespin assignment development log slides demo movie LT slides External Resourcesz80pack ...
