I was on the hunt for old keyboards and a guy in my area was selling off all the parts from his former computer repair business. One picture showed a bit of what appeared to be 70's vintage in a very large case. They were Honeywell Hall effect switches (cool!) but I opened up the case and there was some kind of motherboard in there. He asked for $10 and I walked away happy.
There were no markings on the motherboard that identified the manufacturer but there was a Apple II disk adapter in one slot so I started searching for a motherboard revision that matches the look of this one but I couldn't find one.
Given the nature of the machine (non-Apple power supply, keyboard, and case) I suspect it is a homemade clone, but I thought I should check with people who know. Anything you can tell me is appreciated. Or if there is somewhere else on the board I should look for identification...
Digging deeper, it may be this one... looks the same. Not in an ITT case, though...

It's definitely a clone.
More or less a ][+ style motherboard but set up to use 2732 style EPROMs so it is switchable INTBASIC or Applesoft. Probably a Taiwan or Hong Kong imported mobo.
Ah, they explains the floating point / integer switch, thanks.
It seems to power on, but I'll need to connect it to a monitor to be sure, and locate a floppy drive to see if it will even attempt to boot up. For the price I paid I'm willing to invest a little more to have some fun with it.

It has an RF modulator attached, so you could hook it up to a TV which will take old analog broadcast signals. Floppy drives are cheap and easy to find. They are all over on eBay, etc. For that card you will need a Disk ][ style drive with IDC20 connector. The newer UniDisk 5.25 or Apple 5.25" style drives with the DB19 connector would work, but you'd need an adapter cable.
The TV end of the RF converter is bare wire... it looks like they ripped it out of the TV.

A lot of old TVs just had screw terminals on the back where you'd put the antennae wiring. So that is pretty normal you'd just have bare wires.
Do you have a picture of your computer?
