The possibility of installing USB platform on TDS3000 oscilloscope

[button.ch]

Hello everyone, I have owned two Tektronix TDS3000/B for a long time. Following the guidelines of this forum post, I installed a floppy drive simulator. But I'm still not quite satisfied. I accidentally discovered a USB enabled chip and wanted to install it on the TDS3000/B. I'm struggling to find corresponding contacts for several related functional ports, and I don't know https://hackaday.io/project/172242-extension-card-for-tds3000-scopes/log/179520-the-actual-informations Does the description of the 100 pin port function in this link correspond to the function shown in the attached image. Especially the four functions of INTRQ, NRD, nCS, and nWR. I would like everyone to evaluate my idea and how likely it is to be implemented? Thank you everyone!
