Plan to build one more. | |[[builderpages:speed3ple:ecb-bp-12|ECB-backplane-12]] |1 x working |I got a Siemens 505-6508 PLC case for this. Still trying to figure out a power and wire placement in that case. | | | | | |ECB-SBC-v2-3a |3 x working |Solid board, no trouble at 4, 8 and 10Mhz. 1 built with vintage 7400 TTL at 8Mhz. | |[[builderpages:speed3ple:ecb-sbc-v2-004z|ECB-SBC-v2-4z]] |2 x working |Works fine at 10Mhz w/TTL+CMOS Z80. Got sound, speed switch works, recovery mode switch not tested yet. | |[[builderpages:speed3ple:ecb-sbc-v5i|ECB-SBC-v5i]] |1 x working |Seems to be working and stable at 10Mhz with LS logic and RomWBW v3.0.1. I'm testing this now. Looks great! | |[[builderpages:speed3ple:ecb-z180mk4|ECB-Z180 mk4]] |2 x working |Solid board, no trouble. Works good at (1:1)18.432Mhz with pure LS logic. Got 3 fake Z180 cpu first… | |[[builderpages:speed3ple:ecb-kiss-68030|ECB-KISS-68030]] |1 x under construction|Still not working! maybe I got some bad parts? | |[[builderpages:speed3ple:ecb-mf-pic|ECB-MF-PIC]] |2 x under construction|Completed but un-tested | |[[builderpages:speed3ple:diskiov3|ECB-DiskIO v3]] |4 x working |Angled IDE connector for easy topside CF card access | |[[builderpages:speed3ple:ecb-dualsd|ECB-DualSD]] |1 x working |Works fine with SBC v4z (12Mhz). PCB made from the new Gerber files (Thanks!).\\ Compile RomWBW with SDENABLE.SET TRUE and SDMODE.SET SDMODE_DSD\\ The SD card sockets I have (ebay) needed bending of WP pin.| |[[builderpages:speed3ple:ecb-ramfloppy|ECB-RamFloppy]] |2 x working |R11 version. Built with 8 x xAS6C4008. I used a TLC7705D SMD version. Good read/write speeds! | |[[builderpages:speed3ple:ecb-cassetteif|ECB-Cassette IF]] |2 x working |Built both version, 300+600 baud. Value of timing capacitor C2 is critical. | |[[builderpages:speed3ple:ecb-vdu|ECB-VDU]] |1 x under construction|Does not work yet. Maybe got some bad parts? | |[[builderpages:speed3ple:ecb-vga3|ECB-VGA3]] |1 x under construction|Does not work yet. Maybe got some bad parts? | |[[builderpages:speed3ple:ecb-propio-v2|ECB-PropIO v2]] |3 x working |Runs firmware from RomWBW v2.9.1(v0.95). | |[[builderpages:speed3ple:ecb-zilog-p|ECB Zilog Peripheral]] |1 x under testing |PCB v2, with 1xDART, 2xPIO and CTC. | |[[builderpages:speed3ple:ecb-4pio-r04|ECB-4PIO-R04]] |1 x working |I got it working, will make a new cable and test more. | |[[builderpages:speed3ple:dsky|DSKY]] |1 x working |Completed and is working | |[[builderpages:speed3ple:ecb-ecb-bus-monitor|ECB-Bus Monitor]]|1 x under test |Blinkenlights blinks, but I don't fully understand how to use this… | |[[builderpages:speed3ple:ecb-usb-fifo|ECB-USB-FiFo]] |1 x under test | | |[[builderpages:speed3ple:ecb-prototype-iii|ECB-Prototype-III]]|3 x under construction| | |[[builderpages:speed3ple:ecb-atb|ECB-ATB]] |1 x under test |Got this working, i think, but… | |ECB-SCG |1 x under construction|Status: have PCB, collecting parts… | |ECB-VGM |1 x under construction|Status: have PCB, collecting parts… | | | | | |**Hardware Terminals** | | | |Geoff Graham |1 x Built, testing |Serial RS-232 to VGA/Composite hardware terminal based on Microchip PIC32MX250F128B. Single chip ASCII video display terminal with VT100 and VT52 emulation. | |uTerm-S |1 x Built, working |Serial RS232 to VGA hardware VT-100 terminal based on STM32F030F4P6 CPU.
