List of calculators with magnetic card readers

Of course, HP-9810/20.

The Canon 164P, 167P/P-II and 167P/P-II line also had the Canon 1614P; but all were punched paper/"plastic" cards, not magnetic. As was the Canon SE-600 (paper). They were hand-punched with a stylus:

Can't make out the part number, but you'll notice they are IBM cards used in 50's or 60's stuff. (they are skinny, not the standard 80-column 12-row IBM card) The "holes" were perforated and you used a Port-a-Punch (which was for 80x12 cards) and stylus to knock the chad out. Various calculator manufacturers used these cards when not utilizing magnetic cards. But can't think of them at the moment. The cards had 40 columns and 7 rows.

Canon had magnetic cards in the SX-100/300 series: SX-100, 103("Japanese" version), 105, 110, 310. The main 100/300 difference was the 100s had internal memory only and no I/O ability. Most SX-3xx models had a cartridge tape (not casette). A continuous loop tape virtually identical to a miniturized 4 or 8-track, but a fixed 1 head position track.

All 300's could attach an external memory box (one). And an additional interface plug for peripherals; singly or in a (somewhat) "daisy-chain" attached. But dead-ended, i.e. not a loop (pretty sure). Wish I had some of those peripherals and software.

Sharp used magnetic cards in the CS-363P (was OEM'ed for the Burroughs as the C3660), CS364P, CS364PI-III and CS365P. Don't know if there were others. I don't have any cards for the 363P, but from the slot it appears similar to the 9810 in width.

An old post, I found when Googling the Sharp 364 models, as I couldn't remember the model numbers:

which lists already mentioned items and a few additional ones. One, to my embarrassment, is the Victor 4900. Embarrassing as I have one & forgot.

Also the Sharp PC-3600 programmable calculator used mag cards. Wish I had the manual, as I have one. There was a similar PC-2600, which also used magnetic cards.
