Description: The trusty old PDP  8.

 

What's wrong with PAL10? 
  I've heard the complaint that PAL10 is lacking in features with respect to later versions of PAL8, but that said features could be added back in to PAL10 by a competent PDP-10 programmer. So. What's wrong with PAL10?

Richard Lary-influenced systems family tree 
  To make it clear, there is a family resemblance of a lot of PDP-8 systems. Here's an attempt to sort them all out. 1) R-L Monitor System, aka MS/8. Written primarily and originally by Richard Lary and Lenny Elekman. These two people wrote a stand-alone system called Poly Basic on the R-L monitor system by a conventional... more »

"Pure" postings, please! 
  In the interests of bandwidth, please ensure that cross-postings are used in a useful manner. A lot of topics have nothing to do with the other common alt.computer or whatever groups, while some obviously do. It was rather curious that some people were discussing a system coincidentally called AMOS while an unrelated PDP-8 system also has... more »

CPS-4K for the LINC-8 and other hardware and related issues 
  I suspect few people have had any contact with this system, mostly because it was never written for any hardware except on the LINC-8. Along the way, it shows partially why no "mainstream" PDP-8 software ever occurred "naturally" on the LINC-8. First, what is a LINC-8 besides the obvious? The LINC-8 is a standard "Straight" -8 that got "modified" [to quote... more »

AMOS 
  Just to make everyone's day: AMOS is the name of a [nearly working] minimal O/S for a PDP-8/e with TD8E and one or two TU56 drives, 4K and a teletype. It was developed in Australia by two young students circa 1973, albeit not copyrighted, and was what today we would call "freeware" [and probably almost worth... more »

More about Old-school programming techniques you probably don't miss 
  Test post. I have had three posts swallowed by the previous topic. This one is not posted to a.f.c. in case that's the problem. cjl

Old-school programming techniques you probably don't miss 
  TIME Magazine Person of the Year for 2006 Peter Flass ...Sure, total memory was plentiful. On the PDP-8 we could indirectly address 4K and field switching gave us 32K which was enough for anybody, or even a luxurious 128K on a specialty PDP-8/A. But the 8 could only directly address 128 words of page 0 and 128 words of the current... more »

Thanks to Rich Alderson, PDPplanet, and Vulcan, Inc. 
  My family and I (including my parents, a Sister-in-Law, and a couple of nephews) toured the machine rooms where the online museum is located. We started with a PDP-7 in the midst of restoration that was in use for about 40 years! We next saw a couple of live VAXen heating up a small machine room (no AC), then moved upstairs to see the 2065 and the XKL... more »

TSS/8 
  Well, I have gotten the urge again to try to figure out how to build what is available for TSS/8 and to try to create an RK05 disk instead of the RF08 disk. If I can do that I'll then try to modify the resident monitor code to read/write RK05 tracks. I Know the RK05 can't read/write single words like an RF08 could. But I... more »
