Things that work with the Suzuki QChord, primarily a reproduction QCard that can be built with completely off-the-shelf parts.
You can get one as long as stock lasts at my Ko-Fi shop!
A single cartridge that contains the entire Q-Card library, selectable by dip switches. The flash should be programmed prior to assembly, by concatenating the 4Mbit dumps you can find on archive.org.
A rewriteable reproduction QCard PCB using SMD components. The flash module uses a TSOP32 package. It can be reprogrammed after assembly with the programmer adapter below.
3d printable cases for the flash QCard and multicart QCard. Prints easily with FDM printers.
BOM:
- 2x M3 screws
A cartridge adapter to allow programming the reproduction QCard after assembly. Optional but highly suggested for ease of use.
BOM:
- 1x 36-pin (2x18) card connector slot, 2.54mm pitch
- 2x row of 16 header pins, 2.54mm pitch
To program a flash QCard:
- ensure JP1 is in the "program" position, that is, the middle and top segments are bridged by a solder blob
- insert the adapter in a TL866 programmer with the front as indicated by the outline on the adapter, and insert the QCard with the parts side up as indicated on the adapter
- program using XGPro with the SST39SF040-TSOP32 profile
Optional unless you are going to dump QCards. Very similar to the programmer PCB.
To dump an original QCard:
- ensure that J401 is closed, J402 and J403 are open
- insert the adapter in a TL866 programmer with the front as indicated by the outline on the adapter, and insert the QCard with the parts side up as indicated on the adapter
- read using XGPro with the AT27C040 profile
- there may be one or in some cases two undetected pins, which you can safely ignore
