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 »

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 »

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 »
