Not to leave you in the dark for too long, here are the trivia
answers to the previous edition of Commodore Trivia. I am posting the
answers at this time, and will post the scores and winners in a few
days. This time frame is set up to allow time for any discussions on the
correctness of these answers. By this time, the newest edition of
trivia has been posted. I encourage you to enter it.
This edition of trivia answers has been posted to the USENET newsgroups:
comp.sys.cbm, alt.folklore.computers, and comp.sys.amiga.advocacy. It
has also been posted to the FidoNET CBM Echo.
Feel free to use these trivia answers in newsletters, magazines, and other

-------Commodore Trivia Edition #25 Questions and Answers (BEGIN)--------
Q $180) Most people know what CPU is in a Commodore disk drive, but what
CPU powers the venerable CBM 1525 printer?
A $180) You had better sit down.... The 1525 is powered by an Intel 8039
8-bit microcontroller. Actually, this isn't so hard to believe,
since Commodore didn't actually develop the printer, but used a
Seikosha GP-100 printer mechanism for the unit, and most likely
contracted Seikosha to develop the firmware.
Q $181) What is the maximum number of characters per line on a CBM 1520?
A $181) 80. 22 columns per inch times 3.63... inches of usable paper width.
Q $182) Commodore rarely manufactured its own printer mechanisms. Who's
mechanism did Commodore use in the DPS 1101?
A $182) The Juki 6100 printer mechanism.
Q $183) What is unique about the DPS 1101 printer?
A $183) It is daisy-wheel, but Commodore made other daisy-wheel printers. what
makes it unique is that it is the only such serial daisy-wheel made
for the Commodore line.
Q $184) Which was the first Commodore modem with DTMF dialling capabilities?
A $184) The first to offer some kind of DTMF support was the Commodore 1660
modem. The modem itself didn't provide any DTMF support, but included
a cable to allow the SID to output to the phone line. Thus, with the
SID's ability to reproduce DTMF tones, the modem could tone dial.
Note that this was only possible on the C64, which has a SID. The
first mode to INCORPORATE DTMF into the modem itself was the 1670.
Q $185) Which was the last Commodore 8-bit peripheral drive developed?
A $185) By develop, we are referring to actually produced models. With that
definition, the 1581 holds this title. For models not actually
produced, The prototype 1590-D-1 3.5" 1.44 MB model owned by Jack
Vander White probably was the last under development.
Q $186) What is the maximum size of RAM available for use for program
storage on an expanded VIC-20
A $186) If you discount the screen area (512 bytes) and Color RAM (512 bytes),
up to 28159 bytes can used for BASIC programs and variables (original
3583 bytes and 3 banks of 8192 bytes each), and up to 40448 bytes can
be used for ML programs. (0-32767 minus 512 bytes for screen and
40960-49151).
Q $187) One of the most poular magazines for computers in the 1980's was
COMPUTE! What Commodore content magazine did it give birth to?
A $187) COMPUTE!'s Gazette.
Q $188) In a strange twist of irony, COMPUTE! was itself descended from a
Commodore content magazine. Which one?
A $188) The PET Gazette. The PET Gazette was started in April 1978 by Len
Lindsey. For the first year, the magazine was sent out for free to
at times 4000 people. In August of 1979, Small Systems Services,
headed by Robert Lock, purchased the magazine from Len and changed
the name to COMPUTE. The focus changed from PETs to all computer
systems at that time. The first issue of COMPUTE. appeared in the
Fall of 1979. It seems the relationship between Len Lindsay and
Robert Lock was less than ideal, but I refer readers to INFO #15,
page 8 for the scoop.
Q $189) COMPUTE! underwent a name change very shortly after introduction.
What subtle change was made to the name?
A $189) COMPUTE. changed to COMPUTE! Notice the change?
Q $18A) How were LOADSTAR and Commodore Microcomputing-Power/Play once
connected?
A $18A) In the mid 1980's, LOADSTAR distributed the type in programs for
both magazines in the disk magazine.
Q $18B) What is the fastest Commodore ever clocked a 6502 or derivative
CPU in a machine?
A $18B) The CSG65CE02 CPU, clocked at up to 3.54 MHz in the Commodore 65
(64DX) prototype.
Q $18C) Name one byte that yields the same character when printed and poked
to a Commodore screen.
A $18C) Any byte between 32 and 63 will produce identical results.
Q $18D) Quick, which chr$ value flips to uppercase/lowercase mode?
A $18D) chr$(14)
Q $18E) Quicker, which chr$ value flips it back to uppercase/graphics?
A $18E) chr$(142)
Q $18F) How do you get INPUT to not display a question mark?
A $18F) open 1,0:input#0,a$
