This is a programmer for old OTP fuse PROM chips. Developed and tested with russian 556РТ (556RT) series, however should also be able to work with Western analogs.
The project has been restored from old P-CAD sources, shared on the original project forum (https://zx-pk.ru/threads/15617-programmator-ppzu-155re3-556rt4-i-drugikh ; russian language).
Current versions:
- Hardware v2.3
- Software v2.0
- Firmware v1.1
- Case v1.0
Unfortunately at the moment only a binary version of the software for Windows OS is available.
155РЕ3 (155RE3), western analogs SN74188N, N8223N 556РТ4 (556RT4), western analog 82S126 556РТ11 (556RT11), western analog 82S129 556РТ5 (556RT5), western analog IP3604 556РТ17 (556RT17), western analog IP3624A 556РТ6 (556RT6) 556РТ7 (556RT7) 556РТ12, western analog N82S136 556РТ13, western analog N82S137 556РТ14 (556RT14) 556РТ15 (556RT15)
There was originally no clear license terms defined. I asked at least one of original authors of the schematic; he was not against me opensourcing the design. I am not a fan of this legal stuff; let's consider it public domain. Any improvements are welcome; i will gladly accept them into the repository.
