But portable? That took till '81 as you say. I still have the TV, and with a converter box, it still displays OTA TV just fine; it wasn't great for text display, was something like 40 x 16 -- but that's better than 0x0. There are 9 D batteries --- it lasts about 2 days (48 hours). I used NiCd rechargeables, it lasted about 24 hours between recharges. And of course it had an AC adapter box.
- Someone 6y agoI guess you’re a few years amiss w.r.t. that tv (or do I interpret that 48 hours wrong?) https://en.wikipedia.org/wiki/Television_set#LCD_television https://en.wikipedia.org/wiki/Television_set#LCD_television says “By 1982, pocket LCD TVs based on AM LCD technology were developed in Japan”, so if we’re talking before the Osborne, it must have been a CRT. I don’t see you power that with 9 D batteries for two days. Reading https://en.wikipedia.org/wiki/D_battery#Dimensions_and_capacity https://en.wikipedia.org/wiki/D_battery#Dimensions_and_capac..., 9 D batteries is, at best, 250Wh. So, running for 48 hours would give you a power envelope of about 5W. NiCd batteries decreases that to 63Wh, or to 1½W. Can that power a CRT tv? Also, reading http://michaeljmahon.com/AppleCrateII.html http://michaeljmahon.com/AppleCrateII.html, even an Apple ][ board with empty slots takes 4.2W. For an 8008, you probably can get lower power usage, but who would be willing to sacrifice computer power for portability?
