Has anyone got a couple of the white plastic rivets which are used to
hold the Jupiter Ace case together?
They consist of a 4-point clawed rivet of about 5mm long, and a pin
which pushes down the centre to open it out.
I need five of them ideally - but even two or three would get the case
buttoned up, if not perfectly.
I've checked the local plastic supplier catalogues and haven't found
anything which quite matches up.
Cheers,

Hi,
Some years back, I was asking if anyone had information about the speech
synthesizer
developed for the Altair 8080 by Wirt Atmar of AICS (in New Mexico).
No "hits".
Most places on the web claimed the Computalker was first, given the date as
1976 or 1977.
(Earlier speech synthesizes existed, but they were external boxes that one
interfaced to,
or were standalone (often with a large/weird keyboard).)
Today, I stumbled over a fairly bad OCR of Byte magazine from August, 1976
at
https://archive.org/stream/byte-magazine-1976-08/1976_08_BYTE_00-12_Speech_…
It has two articles about speech synthesizers for S-100 bus systems.
The first is by the Computalker people, who say:
At the time this article
goes to press, a synthesizer
module incorporating several
detail refinements and im-
provements over the circuits
of this article is being de-
veloped by the author and
associates.
and
A detailed user's
guide will be supplied with the
Computalker module
Note the future tense!
The second is by Wirt Atmar, whose product *was already shipping*.
Near the end of his Byte article, Wirt lists currently available products:
At the present time, two speech synthesizers
are both commercially available and affordable by
the hobbyist.
One is the Votrax produced by:
Vocal Interface Division
Federal Screw Works
500 Stephenson Dr
Troy Ml 48084
Price, approximately $2,000
Interfacing: Parallel or Serial (RS-232)
The second is the Model 1000 manufactured by:
Ai Cybernetic Systems
PO Box 4691
University Park NM 88003
Price, $425
Wirt had told me (twenty years ago or so) that he thought his was the first
for microcomputers (e.g., a user installed card, not an external box).
Now, I'm sure ... but it was realllly close!
Wirt demonstrated his product at the earlier MITS World Altair Computer
Conven-
tion, where it won first prize.
He advertised it poorly/infrequently, since it was mostly a side business.
And, that shows, since history doesn't remember it.

You probably know this already, but if you're willing to pay, there are 'pack
and ship' services who will show up at a location, take the stuff to be
shipped, go pack it up, and ship it. I have used PakMail:
http://www.pakmailcanada.com/
several times to retrieve things in this way (they shipped my PDP-11/45 from
Ontario, although the seller did a lot of the packaging in that particular
case), and have generally been happy with them. I don't see a London location,
but maybe one of their other Ontario locations:
http://www.pakmailcanada.com/pakmail-canada-locations
is close enough to be useable?

Were you the winner of the eBay auction? It went for a very reasonable price. It was very difficult for me to not bid on it - those are great boards for use with early S100 systems :)

Hi,
I'd like to apologize for referring to the OCR of the Byte article as a
"fairly bad OCR".
I was thinking of the garbled sections that may be the result of trying to
OCR graphics.
The vast majority of the text comes across clearly, and I don't want to
insult whoever volunteered their time to do the OCR'ing ... I know how
tedious it can be!
I've been spoiled by OCR programs that produce their output as pdfs with
searchable text,
and should have remembered the results I get when I look at just their text!

display.
Although he carefully specified 'general overstrike', I'll still mention
how the HP 2641A (an APL terminal) did it. When about to enter a newly
received character into memory, the terminal checked if a non-blank was
already in that spot ... if yes, it looked up the pair in an internal ROM
table and replaced the existing character code with a new character code
designed for APL\3000 (a code that, when received, would display as the
appropriate overstrike).
That meant that we couldn't use the terminal at Burroughs, because our APL
had a few overstrikes that weren't in the table.

I came across this among some junk I had.

Hi,
First, apologies if I asked this years ago (I've searched my archives, no
hits :)
When was the concept of memory "above" the screen invented for terminals?
I.e., previously displayed data that had scrolled up and off the screen ...
but could be retrieved (usually by scrolling down).
(Sometimes called "scrollback", or "offscreen memory".)
(BTW, I'm talking about terminal-local memory, not a scrollback implemented
by the computer to which the terminal is connected.)
The HP 2640A, 1974, had (IIRC) several pages of memory available ... the
user could scroll
backwards and see what had been on the screen before it scrolled off (as
long
as it hadn't been lost by having too much subsequent output).
I suspect the DEV VT100, 1978, had it, but I can't find definitive proof
online (sure, I can find VT102 emulators that have scrollback, but reading
an old VT102 manual doesn't make it clear that it has it.)
thanks,
Stan
