Looking for Univac 1005 manuals
I've been providing technical assistance and moral support to Stephen Boyd, who has written an emulator for the Univac 9200 and the 1710 keypunch. Now he's tackling the Univac 1005, which is a follow-on to the 1004. The Univac 1004 is what you could call the next evolutionary step from the IBM

Univac "Flow Matic"
Bitsavers recently uploaded a manual from 1958. Flowmatic was a predecessor of COBOL, looks a lot like it. It includes details on the Univac II and peripherals. The Univac/Remington Rand logo includes electrons in orbit, as did so many logos of that era. Also has sort of a helmeted figure

On second thoughts ...
On second thoughts, having previously expressed dissatisfaction at the ARM instruction set for lacking instructions with memory reference, now that the PDP11 thread had me reading again the 1969 PDP11 (NOT PDP11/20) handbook, and realising that memory reference in the PDP11 added extra words to

Preferred colour scheme?
Having been reared on DEC machines, PDPs 8, 11 and 10, which was the better colour scheme, the pink and purple of the 11, the yellow and orange of the 8, the blue and green of the 12 / LINC, or why? The advantage of the blinkenlights approach was that you could, when necessary, get very close
Wallace Tree Correction on Web Site
I've made an important correction to my web page at http://www.quadibloc.com/comp/cp0202.htm Chris Wallace had his paper describing the Wallace Tree adder published in 1964. The IBM STRETCH computer, of course, dates from 1961, and it employed a small tree of carry-save adders. So the
PDP-11 question
I *think* I know the answer to this, but I'd like to be sure. What was the first PDP-11 model marketed? As far as I can remember, it was the 11/20. Is this correct? (I used DOS/BATCH and RT-11 on our 11/20, and I also installed Mini-UNIX on it) -- Using UNIX since v6 (1975)... Use the

Your own PDP8/I clone?
Probably about 50 years ago, my school (Nailsea (Grammar) School) was presented with one of these plastic binary adding machines, and it fell to me as the prototype computer nerd***** to assemble it. I do remember the stick-on paper binary symbols for 0 and 1 ! It was somewhat like an Airfix

Microsoft to keep PAINT program after outpouring of support

What is missing?
What IMHO is missing from the vastness of today's operating systems and languages is an instant access language along the lines of those present in various home computers, and, indeed, the PDP10 (Did my final year assignment on a PDP10 teletype in BASIC) I suggest that what is needed is a
Dell vs. Lenovo for a PC
Anyone have an option which is better-built hardware--Dell or Lenovo for a PC (tower type)? Thanks
The missing link?
Most historical works seem to jump from Babbage to Turing with nary a mention of Conrad Zuse.
The changing times?
Back in the days when I was fortunate to be introduced to the world of minicomputers, it seemed that manufacturers were falling over each other in their eagerness to describe every aspect of their creations, with copies of the processor manual on free issue. Nowadays? What of the graphics
Were we the lucky ones?
Were we the lucky ones, we who experienced mini computers in the late 1960s and early 1970s because with little more assistance than editors and assemblers, we got to understand our machines in some depth and if we wanted operating systems then we wrote our own? I am grateful for that

off topic. excerpt from CNN Boeing (BA) earlier this month flew a 747-8 Intercontinental back to the company's base in Washington state from a paint shop in Portland. It was wearing the colors of Korean Air Lines and it is extremely likely that it is the last passenger 747 to ever be built.
