Hello all,
I developped a Windows software in order to emulate TU48 tape player (an old numerical drive, mainly used to store PDP-11 bios). PDP-11 is used for example on Aciera milling machine.
This program uses the RS-232 link of PC (serial link) to communicate directly to the PDP. It can both get the bios data from the PDP and store it on the PC or send the saved data to the PDP.
I wrote this program to avoid all the mechanicals problems raised by the TU48. It works fine on an Aciera F55 and an Aciera F45.
