| Floppy Disk The Floppy Disk DMA is now implemented and working. The picture shows the start of three sectors in one track read into chip ram. The data is still encoded in MFM. 
For now only the read mode in 880k is enabled. The others will follow when I can test them. Frame generation ...... ECS, fixed 28MHz pixel clock
SyncZorro Interface ... preliminary version
Copper ................ fully implemented
Video DMA ............. fully implemented
256 color registers ... fully implemented
Sprites ............... 16bit linebuffer
blitter ............... o
Video priority ........ half implemented
Scandoubler ........... fully implemented
Interrupts ............ fully implemented
Paula DMA control ..... fully implemented
Audio out ............. o
VGA out ............... working
DVI out ............... o
PCI ................... o
IDE ................... o
CIAs .................. fully implemented
(new) Disk DMA .............. DD, read only
Serial Port DMA ....... o
Slow peripheral I/O ... fully implemented
(Joy/Mouse/Keyb/PRT/DSK/SER)
Fast RAM controller ... o
Kickstart flash logic . o
15k Video out ......... o
15k Video in .......... o
Audio in .............. o

| Only the Amiga community would find floppy access exciting. Who else still uses these devices? The last time I needed to boot my PC to do an update I used a CDR.

| I use a lot of floppies for hardware synthesizers/samplers.

| Flashing a BIOS, but i suppose i could use the root directory of a HDD for that too if Windows allowed it. :P (Linux would be a option it it wasn't that limited to FS type.)
Yeah BIOS flashing, I am not wasting a CD-R on that.Besides it's great it's not terrific, read the somewhat sarcastic undertone. ;)

| Thomas - Nice work. I like the way you show the status of each mini-project with the changes each week or two as you go along. Perhaps we could see something similar for the 68050 core? Hint. Thanks

| It is very important that the Natami can have a floppy disk drive attached as virtually all Amiga software is on floppy disk, without it the Natami will have no software until it is released on cd/dvd.
Amiga compatibility includes being able to run software from floppies.

I coldn't agree more on that! It would be just lovable to insert some old "Giana Sister" etc. floppy game and enjoy it once in a while on a NATAMI!

Erm well we could also put ADF on some other media (stick) and read those of course.

| Yes we could but it is not as convenient if, like me you are up to your neck in floppy disks:)

| Only the first generation would need the option of a floppy disk drive, in a year or two we will probably have the most useful software on SD card or similar.
I have an 8 DVD set containing most if not all Amiga software, but most new users may not have that, it may be possible to download software off the 'net, but it's legality is questionable.

| this done list look maybe a little strange, because years ago is a working natami see. So wy can it happen that now blitter and some other features AOS need listet as not work ? My guess here is, that it is not so easy to move old code to new FPGA with other size and nm size so you must adjust some delay lines to avoid runtime influence because modern chips are smaller.
