Daisywheel Question
Typically, a daisywheel had 96 petals on it for 96 printable characters. Some had 94 characters instead, because that's all ASCII needed, and some had 88 characters. But there were daisywheels with more characters. The NEC Spinwriter, not technically a daisywheel, because it used thimbles

1961 electronics catalog
Allied catalog. The hi-fi revolution was in full swing, with many pages devoted to hi-fi equipment. Back then hi-fi was a big status symbol in the suburbs, with many people getting a huge expensive system 'cause it looked cool, not that they appreciated the sound out of it. Lots of electroni

The Selectric Golfball is Hard to Measure
The diagram of the Selectric printing element in the patent (US 2,895,584) on the Selectric typewriter shows four bands of letters going around the element which are vertically symmetric - the letters on the top band are opposite the letters on the bottom band. I had thought that the real

Fantastic Voyage on TCM On Demand
Speaking of this film, it may be viewed now for a few days. For its day, excellent special effects. Lots of computer images. The secret facility looks more like a subway concourse, but still neat. Some of the plot lines have obvious holes in them, but still interesting.
OT (Severely OFF TOPIC) What makes for a radio ham? (IMHO)
Taking a reductio ad absurdum, were a government to rule that anyone buying a packet of BandAid sticking plasters was now a doctor and could practice in any hospital, would such people actually be doctors? Of course not. BY the same reasoning, in amateur / ham radio, it is the individual's
Why did OS/2 fail?

Harking back
Now, I know this to be a folklore group, but harking back to my first experiences with PDP11 assembler***** in 1971 is something that was 48 years ago, and 48 years before that takes us back to 1923 and there's no way that I'd be interested in the computing technology of then, save that I have

CALL $FORK ----- really just a JUMP!
In 1978 I did the RSX-11 Systems Programmers course at DEC in the Butts Centre in Reading and I remain impressed to this date with D (Dave?) Cutler's ingenious mechanism for speeding up interrupt latency for nested (lower priority ) interrupts meaning that as little time as possible was spent
The PDP11 and subsequent influences
Has any other architecture influenced subsequent designs in the way as did the PDP11? 6809, 68000, to name but two, and excepting the whole of the Intel designs going back to the 4004? I often wonder if 4004 was chosen because it is the date that fundamentalist christian religionists claim
PDP8 Instruction Set
AIUI, because the design work was done for the Yank Dod, the PDP8 instruction set was in the public demesne? I'm curious as to whether the subroutine calling mechanism, that of storing the return address at the start of the subroutine, was modelled on the practice of mainframes at that time?
