Default Re: Retired Texas TI99/4A engineer needs help please.

Wow, lots of useful help there. I was thinking in excess of an amp from the 5v rail, this powers the optional speech synthesizer and the cartridge port as well.
Am I correct in thinking that as I am getting +5v from the output driven by the UA723 that this chip is likely to be OK?
