Re: [midatlanticretro] MARCH's PDP 11/05's
- I have learned that PDP 11 series is very robust and are easy to work on. If you're looking to get into something, I would suggest the PDP 11/05 because it's PC sized and parts are easy to come by. Much easier than an early S-100 system. I don't understand by more people don't collect 11/05's, this is the smallest PDP 11 from the 4 1972 models, and IMHO is a personal computer, even if they were not marketed that way.

Bill, It's fabulous that you got them both to do anything! Jim B Degnan wrote:
All, I was able to take apart and clean the two MARCH PDP 11/05's. They're both essentially identical 4K core RAM systems. One has a stuck 7th databit in most address locations, but the other 4K Core memory card is OK. With the good card I can call/write/retrieve memory along the 4K pages on either machine. If we can find another RAM card they'd both be usable. One of the two also has a serial interface card set to 300 baud (I believe). There is no OS, so that's about as far as I can go with it short of toggling in a boot strap etc. Bill
