[How] to check long term and short term fuel trims
Do you know of a way to check long term and short term fuel trims on the Gen 1's?
Will a high end scan tool do that on obd1 systems? I have not found any information on it.

Sorry that I don't know the situation there in US. Here in Japan, you need to use a special scan tool manufactured by Denso to measure the fuel trim for older Toyota cars before the S2000 for UCF20/21 and others was released. Both those tools were only sold for authorized dealers though.
The link below may help you some.

Oh and you do need the power cable to connect to the battery, I don't know why.
