I aquired a HP 2671A thermal printer and know that there should be an
upgrade ROM to 'upgrade' it to a HP 2671G.
Thanks to Tony excelent work on HPCC CDROM i have the schematics and was
able to fix the head positioning circuit.
One of the driver transistors (TIP 122) was bad after replacing it and
cleaning the printer it works fine.
But now I want to use it for printing graphics (diagrams) and would be very
happy whith an image of the graphics ROM.
