Oh gosh, I remember in college, playing with PCMCIA cards in laptops, and you'd have to kinda point them at each other. Can anyone confirm if that could be correct, or that I'm actually misremembering something?
- Tade0 6y agoCan't confirm because what we had instead was a task to implement a custom protocol over an RS-485 linear bus. The device in question was only available on appointment, so we only had a few shots at this. Eventually we went with adding a checksum and resending the whole "packet" (one byte) when it didn't match, because we couldn't get the damn thing to send stuff correctly 100% of the time.
- downrightmike 6y agoI had a pentium laptop with a IR port built in back int the day, circa 98
- rasz 6y agoI wasnt familiar with any dedicated IRDA PCMCIA cards ever existing. But apparently IBM made one :o https://www-01.ibm.com/common/ssi/ShowDoc.wss?docURL=/common/ssi/rep_ca/6/897/ENUS194-436/index.html https://www-01.ibm.com/common/ssi/ShowDoc.wss?docURL=/common... or https://groups.csail.mit.edu/mac/ftpdir/thinkpad/old-archive/HTML/tp-1994/msg01797.html https://groups.csail.mit.edu/mac/ftpdir/thinkpad/old-archive... only picture I could find of one: https://www.ebay.com/itm/0934340-IBM-INFRARED-WIRELESS-PCMCIA-ADAPTER-NOS-0933878-/142052774528 https://www.ebay.com/itm/0934340-IBM-INFRARED-WIRELESS-PCMCI... Still you wouldnt be aiming whole computers with pcmcia cards in them, there was a dongle, most likely with a clip or velcro to slap in on the back of laptop screen.
