DS1000 delay line adapter
DS1000 is an open-source printed circuit board by reinauer, from the reinauer/DS1000 repository on GitHub. It is a 2-layer board of 9.8 × 18.4 mm with 2 parts on 13 nets, routed with 50 tracks and 8 vias.
This project lets you use SMD delay lines on old iron like Amiga computers.
Newer (A3660) accelerator boards have a footprint for the smaller SOIC part on the PCB already. But if you are rebuilding an Amiga 3640 accelerator, this will let you use the much more readily available SOIC version of the DS1000 (e.g. DS1100z)

| Qty | Value | Footprint | References |
|---|---|---|---|
| 1 | DS1000-25_(SOIC) | DS1000:SOIC-8_3.9x4.9mm_P1.27mm | U1 |
| 1 | amiga.technology | Package_DIP:DIP-14_W7.62mm | DS1000 |
It measures 9.8 × 18.4 mm and has 2 copper layers, 1.6 mm thick.
2 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the reinauer/DS1000 repository on GitHub, at the commit this page was made from: the board is DS1000.kicad_pcb and its schematic DS1000.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask reinauer before reusing the design.
