[emu71] - about :HDRIVE1

[MattiMark]

I have been trying to initialize a HDRIVE1 for the emu71 v. 1.06 in order to transfer a SOFTROM of the MATHROM into a physical HP-71B. But it is not working out any well...

emu71-vice:
I have loaded the HP-IL--ROM into port 0.
MATH-ROM into port 2.

The HDRIVE1.DAT is 32 KB and in the same folder as the emu71.exe

When I run the command: INITIALIZE :HDRIVE1, 2000 I get the error message;
HP-IL ERR: Device Not Ready.

I have a HP-PIL BOX and a 32 KB RAM for my HP-71B. Have not yet cutted the cables. When I connect the PIL-BOX I get 3 blinking red LEDs.

Questions:
1. How do I format the HDRIVE for use with the emu71?
2. How shall I do in order to proceed with my task?

TIA
