It seems that the BBC micro falls foul of the same issue as the Brake Testing Machine - http://forum.retroprinter.com/viewtopic.php?f=4&t=26

Tbe BBC connects pins 19 to 32 to GND, and so were draining the 5V from the Raspberry PI. :(

We have one user with a BBC Micro B who found that he needed to disable the 5V to connect the Retro-Printer to his BBC. After that, it works correctly, and he can print from Interword.

However, when he tries:
<CTRL><B>
LIST

the BBC prints two lines and then sits waiting for the printer.

Any ideas why the LIST command doesn't work, but Interword does? We are sending the correct ACK signals etc.... Should pin 13 on the centronics be connected on the BBC end (and maybe it is a problem with the centronics cable)?

The problem with using LIST from BASIC was fairly easy to resolve....

For some reason, this BBC Model B defaulted to sending the printer output to serial.
A quick:

Code: Select all

 *FX5,1
resolved it - although why the default is not parallel (as per the user guide) is beyond me.

Hi Rich,

I tried this on an Acorn Electron & Plus 1. The Plus 1 adds a printer port to the Electron.

To get the screen ouput spoolng to the printer, affter CTRL B. I had to issue *FX6,1 and the everything on screen went the printer via RetroPrinter correctlt.
