New Features
RCT programs EPROMs
The RCT can now also program several EPROMs. This requires a simple, inexpensive adapter that provides the programming voltage. This feature is currently classified as experimental and I would appreciate your feedback on it.
Supported are following EPROMs: 2708, 2716, 2532 and 2732
Improvements
- The ROM padding of 4-bit ROMs can be selected between 0 and 1.
- „Misc Logic Tests“ menu splitted into two menus.
- Memory with a data bus width greater than 8 bits can be dumped, MSB is saved first.
Bug fixes
- Small bug fixed that saved random data for analyzing purpose was not correct.
New Adapters
- 2708 Programming Adapter
- 2716/2532 Programming Adapter
- 2732 Programming Adapter
The Gerber data for the current version of the adapter has already been published. The schematics of all adapters are available in the BOM.pdf now.
