-------Commodore Trivia Edition #27 Questions and Answers Preface--------
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
publications (please see disclaimer). If you use the trivia, I would
appreciate knowing where it has ended up. If you intend to use this
information, please wait a few days after the posting date to allow for
major errors to be corrected.
Please mail any new questions for upcoming trivia (with answers) to my
address.

I try to post the answers for the questions shortly after the monthly
contest has ended. However, I usually wait a few days for any errors
I may have made to be worked out before scoring the contest.
-------Commodore Trivia Edition #27 Questions and Answers (BEGIN)--------
Q $1A0) Commodore produced an assembler for the 128 called HCD65. What
does HCD stand for?
A $1A0) Hedly C. Davis, the writer of the assembler.
Q $1A1) Who wrote most of RAM DOS?
A $1A1) Although many assume Fred Bowen wrote RAMDOS, Hedly Davis actually
wrote the bulk of it.
Q $1A2) What is the name of the first C64 disk copy program? (hint: it
sported a "gas gauge".)
A $1A2) 1541 Backup.
Q $1A3) What was the case color of the original Commodore 64s?
A $1A3) Ivory, just like the case color of the VIC-20. In fact, early
cases WERE VIC-20 cases.
Q $1A4) There are at least two ways to enter 64 mode from 128 mode on a C128:
go 64 and sys 65357. They produce the same result (64 mode), but
they differ in at least one noticable way. How?
A $1A4) sys 65357 doesn't ask the "Are You Sure?" question.
Q $1A5) What CPU powers the B-128 computer system?
A $1A5) The 6509 CPU.
Q $1A6) What type of drive mechanisms are in the D series hard drives from
Commodore?
A $1A6) The D9060 and D9090 drives used "Winchester" hard drive mechanisms.
Q $1A7) Commodore produced a 16kB RAM expander for the Commodore VIC-20.
What is its model number?
A $1A7) The VIC-1111.
Q $1A8) Commodore produced at least one disk drive with an optical track
one sensor. Which drive?
A $1A8) Certain early versions of the 1541C drive had a functional track
1 sensor. Later, due to compatibilitty problems, it was disabled,
and then later, the sensor was removed from the mechanism.
Q $1A9) The Commodore PET series used the IEEE bus to communicate with
peripherals. Each peripheral had a unique ID. What range of IDs
are supported by the PET?
A $1A9) IDs 4-15 are supported, although you cannot connect all 12 devices
up at one time.
Q $1AA) Many people have developed Commodore software with the PAL assembler.
What does PAL stand for?
A $1AA) Personal Assembly Language (PAL).
Q $1AB) Many people remember Compute's Gazette. This magazine is best known
for the word processor program it shared with thousands of
subscribers. Name the program?
A $1AB) SpeedScript.
Q $1AC) In some 6502 assemblers, the opcode "bge" is available. It stands
for "branch if greater than or equal to". What more common opcode
is this opcode referring to?
A $1AC) bcs (Branch Carry Set)
Q $1AD) If I wanted to do a "blt" (branch if result less than), what 6502
opcode would i use?
A $1AD) bcc (Branch Carry Clear)
Q $1AE) Each Commodore peripheral has a device number, which is associated
with a type of device. 8-15 implied disk drive, 4-5 implies
printer. These have remained constant from the PET to the C128.
However, one peripheral in the PET was phased out and its device
number was reused. What device number was reused?
A $1AE) Device #2. The PET systems used #2 as a second tape drive, but in
the newer computers, #2 referes to the RS-232 port.
Q $1AF) What is the maximum amount of general purpose RAM can one utilize
in a stock C64? (I need an exact number here)
A $1AF) In the Ultimax memory configuration, if you guarantee no interrupts
can occur, one can utilize all but the first two memory locations
for general purpose RAM, giving 65534 bytes of RAM. If you can't
guarantee you'll never receive an NMI, you lose 2 more bytes for that
vector, giving 65532 bytes available.
