Hi,

I have a HP9820A and a plotter HP9862A with its interface cable. Unfortunately I can't use the plotter because a ROM in the calculator is required for this.

If you have Peripheral Control I ROM with the number 11220A to give away or to sell, please contact me: thfalk@gmail.com

Best regards,

Thomas Falk
