Ok, better late than never, but here's all the Ten X stuff I have ATM. This is a smallish Nextcloud server that will need to be moved to...

I have a copy of the 9402 Problem Analysis Guide I didn't remember owning that's got some MAPs and stuff that you'll probably find...

I had trouble on my 9402-F02 with the on-side of the EPO switch being faulty. Test it with a multimeter. Mine was dual-throw so it was...

That's an internal clock doubled frequency. You're actually trying to run it at 50 MHz by installing it in a 25 MHz board. So that's...

the diagnostic disks are standard pc style format. double sided, 18x 512b, 500k data rate (1440kb). if you ran out of space you were not...

The PLD is a Mac thing for decoding what amounts to a "double" SIMM.

KM41C400 is 4 megabit (each chip gives 4 M x 1 bit). 8 chips gives you 4 MB. 4 SIMMs each with 8 chips gives you 16 MB. HY514400 is...

Regardless of console, there is no output during self-test. Only the front panel LED codes. All of (more or less) the chips on the CPU...

This turns out to be the key fact, and the key misunderstanding I had of the system: I assumed that, even without the RTC chip...

hmm, that's not very good. but I think there's not much you can actually have killed besides the RTC, with it in backward. You end up...
