HP 2647A Intelligent Graphics Terminal from 1980

Display: 12" white CRT
Display Format: 24 lines x 80 columns, 720 dots x 360 rows (graphics)
CPU: 8080A @ 2.4575MHz
RAM: 64KB
ROM: 64KB
Ports: HP-IB, RS-232
Model: 2647A
Serial Number: 2020A03434
Notes:

This terminal has a severe case of screen rot, as do many others of its age. One of the tape drives has been pulled for repair, because the rubber on the capstan has deteriorated. The rubber on the remaining tape drive is intact, but has turned tacky and must be replaced before use. A set of manuals came with the terminal, as well as a batch of tapes. Three of the tapes are the User Instruction tapes (02647-13302 and 02647-13303), and the Multiplot/BASIC Interpreter (02647-13301).

In order to get this terminal working, I had to replace two 4116 RAM chips on the first Universal Memory PCA. It now passes all self-tests.
