It depends how much free time you have. I would

All of the ICs are socketed in this 680.
Oh, in that case, go for taking them all out if you want. In the two 680s
I've worked with everything but the ROM, processor, and 6850 was soldered
to the PCB! : )
I was wondering about getting a copy of VTL-2 in
ROM/EPROM.
$30 + shipping, or less if you want to mail me 3 good 1702s.
Just a
pointer, when the Altair 680 is working *properly* the heatsinks
(especially the upside down one) are hot/burn to the touch. Same thing
with the 2W resistor.
That's good to know.
The ACIA is normal temperature, the 6800 gets kind of warm (do you have a
ceramic one?), and the 1702 can get pretty warm. This is based on the
surronding ICs.
I've learned a lot about debugging Altair 680s. I've repaired 1, and built
2 more from scratch in the last few months. : ) Its a pretty easy
computer to work with. I like it.
