Mostly Z80 ECB stuff here…
| System/Board | Status | Comments |
|---|---|---|
| ECB-backplane-4 | 2 x working | Nice little test bench |
| ECB-backplane-8 | 1 x working | This is the backplane I use the most. Plan to build another. |
| ECB-SBC-v2-3A | 3 x working | Solid board, no trouble at 4, 8 and 10Mhz. 1 built with vintage 7400 TTL at 8Mhz. |
| 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. DS1210 bypassed. |
| 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… |
| ECB-KISS-68030 | 1 x under construction | Project startup… |
| ECB-MF-PIC | 2 x under construction | Project startup… |
| ECB-DiskIO v3 | 4 x working | Angled IDE connector for easy topside CF card access |
| 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. |
| ECB-RamFloppy | 2 x working | R11 version. Built with 8 x xAS6C4008. I used a TLC7705D SMD version. Good read/write speeds! |
| ECB-Cassette IF | 2 x working | Built both version, 300+600 baud. Value of timing capacitor C2 is critical. |
| ECB-VDU | 1 x under construction | waiting for parts… |
| ECB-VGA3 | 1 x under construction | waiting for parts… |
| ECB-PropIO v2 | 3 x working | Runs firmware from RomWBW v2.9.1(v0.95). |
| ECB Peripheral | 1 x under testing | pcb v2, with 1xDART, 2xPIO and CTC |
| ECB-4PIO | 1 x under testing | With only 2 PIOs, corrected pcb with wires |
| DSKY | 1 x under construction | waiting for parts… |
| ECB-Bus Monitor | 1 x under test | Blinkenlights blinks, but I don't fully understand how to use this… |
| ECB-USB-FiFo | 1 x under test | |
| ECB-Prototype-III | 2 x under construction | |
| Non-ECB systems: | ||
| Zeta 2 | 2 x working | Stable at 16Mhz(LS) and 20Mhz (AHCT). 1 built into a metal case together with ParPortProp as a unit |
| Easy-Z80 | 1 x working | Small and easy to build. I got the v1.1 pcb. Nice! |
| Z80-GrantS | 1 x working | Small pcb based on Grant Searle Z80. Runs basic. |
| ISA bus boards: | ||
| ISA Micro8088 | 1 x working | |
| ISA backplane | 1 x working | |
| ISA XT-IDE | 2 x under testing | |
| ISA Super-VGA | 1 x working | |
| ISA-XT-CF-Lite | 2 x working | |
| ISA-FDU-Serial | 1 x working | |
| ISA-RTC | 1 x under construction | |
