HP 21xx update

So, I'm mostly recovered from the move to UT and I've gotten back to working on the HPs I acquired. http://rikers.org/gallery/hardware I've fixed the visible issues with the HP-2116A and powered it up slowly with a variac with a minium of cards installed. Fans spin up ok, I get a couple of the power circuits live, but fuse F8 blows and the rest of the power circuits do no come up. No lights on the front panel etc. I'm reading through the HP-2116B vol2 manual on bitsavers (Thanx Al!): http://bitsavers.org/pdf/hp/2116/02116-9153_2116B_Vol2_Oct70.pdf But there are some differences in the power supply between the 2116A and 2116B. I don't have an A1 card for example, and the core memory is completely different. I'm kinda beating my head against the wall on this one. Still hoping Bob or someone else will dig up a Volume 2 manual for the 2116A sometime soon. =/ In the mean time, I've repaired and powered up the HP-2108A system. Things seem to checkout ok. Now anyone want to suggest a light chaser program to key in for kicks? I don't have any manuals specific to the HP-2108A here, but I suppose I should try some of the memory diagnostics routines from the 2100 or 2116 to check things out. The basics seem to work. I can store/recall values from registers and memory. I've not tried all memory locations or anything yet. I'm hanging out on #classicmp on irc.freenode.net as usual. I was hoping Jay would be around sometime or others that might suggest what to do next. ;-) My paper tape reader seems to spin up ok now, but I've not tried to talk to it in software yet. Also I don't have real tape images for things like the basic1 environment: http://oscar.taurus.com/~jeff/2100/hpbasic/basic1.abs I've got my hacked simh that has ANSI text register displays to test out routines on. That's been very useful. ;-) Any suggestions on getting pc based paper tape images over to real HP hardware? I do have a paper tape punch, but no docs on it. Also I don't currently have any blank media.
