Hello All. the LED on my upright starcastle CPU board stays on when powered up. I checked the 5v dc and its fine. I went ahead and ordered a new 74LS259 and 74LS32 just cause they are on the frequently failed parts in the maintenance manual. Just wondering if anyone had any input or experience with this issue in the past. Thanks!
 
You just need the right tool. Contact Bill and see if has any more of these available:

I was familiar with Sig Analysis from Atari's, so the learning curve wasn't steep- but Cine's are more unstable (thanks to Bill for verifying that I wasn't losing my mind and I hadn't assembled the harness poorly). My first Armor Attack took a while as I tested pretty much every IC before finding it was only 2x bad RAM. My second AA went quicker, 3x bad TTL ICs and 1x PROM, plus pulled and socketed the 3x RAM all in under 90 min including diagnosing and repair.
