Apple II

Does anyone know how to perform a serial loopback test at a BASIS-108 computer?

More interesting is the question what cable needs to be used to transfer data via ADTPro to a BASIS-108, because a Null Modem cable doesn't work (as normally when using an Apple IIe instead the BASIS-108, for example).

I'm trying to get an Apple II+ clone fully working (it boots up like it should, but there's no response from the keyboard -something I'm looking into, suspecting the keyboard itself needing repair). However, there are some other things worth considering like the power supply output. With the computer switched on I measure these voltages:

- 12.009 V+ 11.480 V+ 4.998 V- 5.033 V

My concern is the +12V line. Is it too low? if it is, what action will likely remedy this?

I have an Apple IIgs setup that I would use more if it wasn't for the monitor.

It's the AppleColor RGB A2M6014. It works okay, though some of the geometry could use improvement, but it runs too hot.

By "too hot" I mean that after it's on a while, I can smell the hot electronics, unlike every other vintage CRT I have, and soon after that I can smell the hot plastic of the shell. It's not pleasant and doesn't seem right.

Hello,

New member here.

I was wondering if someone might know anything about the books below which we found while decluttering? What are they, what are its significance (if any), etc.?

I did a search earlier for Fred White (the author of one of the books) to know more about him, but wasn't sure which of the results besides the ones that come up on Amazon but with incomplete biography, was him.

Also, the Applesoft Tutorial book is unlike those I see online, most of which are spiral bound while mine is paperback.

Any input is greatly appreciated.
