I just received the Calculator Buyer's Guide 1978 - 1979, puplished by Application Calculators Incorporated in 1978.
It covers not only the HP and TI products but includes Casio and Sharp and features such iconic calculators like the Casio fx-8000 and Sharp CT-500/CT-600, EL-5804/5806/5808.
Pretty intereting to see a HP-10 compared to a TI-5025 or a TI Datachron next to the Casio AQ-1000. Overall, with technical data and a pricelist, an incredible resource for us calculator collectors.
Short question: Are there Buyer's Guides from Application Calculators Incorporated out covering earlier or later years?
What happened to the company? Not a lot on the web - just a nice patent application for a calculator display stand ;-))
Thanks and Regards,
Joerg
