Hi all, I've been fortunate lately. Recent system arrivals include a Motorola Exorcisor&Disk and MEK 6800d2, an OSI Challenger iii and replacement power supply, an OSI Challenger 500 with a chunky doc set, a MITS 680, a KIM-4/hb tvt-6/etc...,and a Heathkit H-11/H-27. Frankly, I'm overwhelmed, but enjoying it. It's hard to find all the necessary time each of these machines are screaming for between all my other grand schemes but I manage. I've been pretty quite lately but lurking when I get a chance and as usual have enjoyed it all. I know there's alot on the h-11 in the archives and I'll hit them too but I know zilch about it right now. The cards in the tilt out qbus(?) are: 1. Digital M7264 2. H-11-5 Serial i/o 3. H27 Floppy i/o 4. H-11-5 Serial i/o 5. M8044 CB 6. M9400 YB 7. WHA-11-16 16k x 16k Memory First question, does it matter how these boards are plugged into the backplane? If so, where do they go? What are boards #6 and #7? The WHA-11-16 had a memory chip that was partially popped out and the right drive latch on the H-27 is cracked but repariable I think. Next question, anyone got a recommendation on where I can find that rectangular(4x6 pin) serial connector? And lastly, dc on, dc off... ??? I'd appreciate copys of any docs for this thing anyone is willing to copy (and software too...) My goal is to get rt(h)-11 and some decus? software (a c compiler) software humming. Thanks for any help - Mike: dogas(a)leading.net
