Wang 700 ROM Reader
The Wang Wire Braid ROMs are now fifty or more years old. They were fragile when first made and operated near to their technical limits, requiring individual adjustment for optimal performance. It’s quite reasonable to be apprehensive about the operating state of any such ROM today. Furthermore, since all functions of the Wang 600 and 700 machines are generated by microcode, a single bad bit in a critical area can bring down the entire machine and render it dead and unresponsive.
With these considerations in mind, it was easy to see the need for a stand-alone ROM reader that could
- dump the contents of a ROM and
- exercise the ROM to test if it was reading consistently.

DoPECC is keen to build a library of Wang Calculator Microcodes. When used with the DoPECC ROM Emulator these codes allow matching machines with defective ROM to be restored. If you have ROMs that you are interested to read, see below for details of how to obtain and use the ROM Reader
