Trying to fire up my old calculator for both museum and practical purposes, thank you for a great online resource! Had to use power supply as the BP-78 is missing.
Im standby verbraucht der nur 19 Mikro Ampere - das reicht für 7 Jahre. Ich betreibe den nun aber mit einem 9v-Block. Vielleicht ist das noch interessant für deine ic Liste. Ich hab einen sehr alten Programmer (LTA4877) mit dem Za0675 chip. You may like to correct the battery type information on your model information here: Your site is great, with a lot of information. I tried to insert 2 x LR-44,but it is impossible as it doesn't fit.
It uses 2 x LR-43 type as indicated in the back cover. I have just acquired one of these machines, and I have an information concerning the batteries. I just changed my battery this month (November 2016) for the first time that I can remember, since purchasing it back in the day. NNovember 18, 2016: I have a TI 1100 II calculator Used fairly regularly, still sits on my desk fully functional and interestingly still on the original battery! December 22, 2016: Texas Instruments TL-30 Galaxy calculatorįound your details on the web after googling my Texas instruments
