| + | ====== ECB DualSD card ====== | ||
| + | |||
| + | PCB made by JLCPCB from the new Gerber files, but had to rename some files and re-zip before uploading. | ||
| + | |||
| + | Compile RomWBW SBC.ASM file with these switches:\\ | ||
| + | SDENABLE .SET TRUE\\ | ||
| + | SDMODE .SET SDMODE_DSD | ||
| + | |||
| + | Hardware:\\ | ||
| + | The SD card sockets I have (ebay) needed bending of WP pin and a small cut with a knife to the GND pad next to the WP pin to ensure no short there.\\ | ||
| + | I used a 9pin 33K SIP resistor in RR3 and a 9pin 1K in RR1. Schematics show that a 10pin is not needed at any of these. All TTL is 74LS. | ||
| + | |||
| + | Jumpers:\\ | ||
| + | The P3 and P4 is like this: [818881] as in 8=open, 1=short.\\ | ||
| + | I'm not sure how to use P6 settings for IRQ.\\ | ||
| + | The K2 Reset is set to Kontron std. | ||
| + | |||
| + | Seems to be working fine together with SBC v4z, DiskIOv3 and PropIO | ||
