I know there are some vintage tech guys on here, last weekend I picked this up at a car boot sale, 1970s ( I presume ) Texas Instruments SR-51A, only to find out when I got home its doesn't take normal batteries, its a rechargeable battery pack meant to be used with a power supply, the cells are AA sized but its not a simple matter of dropping them in, the connectors are soldered on to make the circuit, doing some research, there are aftermarket modified packs that can take the AAs but as I don't know if it even works Im loath to buy one ( from the USA it seems ) until i know it works. Looks pretty clean inside and the cells hadn't leaked so Im optimistic.
Does anyone here have one that would be willing to take mine and test it with their BP1A working pack ?
I couldnt leave it behind for the sake of 80p It even has a case.
