Need information about the Bell/Sumlock Comptometer ANITA calculator Mk 1. Supposedly it was built entirely of vacuum tubes (which makes it grist for our series of tube-computer articles in VACUUM TUBE VALLEY magazine). Can anyone supply a good-quality photo of an Anita, plus possibly a photo of the insides? And any available technical details about its circuitry, plus a bit of historical data.
We can pay up to $60 for such photos.
Thank you for your assistance. Call me at (650) 233-0429 in USA if you have questions.
