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

Q $152) The Commodore 6510 CPU has two internal I/O registers. Where in the
Commodore 64 are these two registers located at?
A $152) Location $0000 and $0001
Q $153) The Commodore 64 cotains 64kB of memory. How many bytes is in
64kB?
A $153) 65536 bytes
Q $154) What is the name of the Commodore employee responsible for much of
the Commodore 128 and 65 software development, among other
accomplishments? (hint: initials are FB)
A $154) Fred Bowen.
Q $155) In question $13F, we found out the message that was displayed after
typing SAVE "",2. Why did Commodore change that message on the
VIC-20?
A $155) The original message, as detailed in Q $13F was:
PRESS PLAY AND RECORD ON TAPE #2
Commodore found that people were pressing the play buttopn BEFORE the
record button, which would prevent the record button from functioning
in some cases. So, Commodore changed the message to:
PRESS RECORD AND PLAY ON TAPE
To circumvent the problem. Note that the VIC did not have 2 tape
interfaces, so no cassette number was needed.
Q $156) What was the number of Commodore 64 machines sold, within 4 million?
A $156) 17 million (This information came from Dave Haynie)
Q $157) What was the number of Commodore 128 machines sold, within 1 million?
A $157) 4.5 million (This information came from Dave Haynie)
Q $158) In 1985, Commodore previewed the Commodore LCD Laptop computer at the
January CES show. How many software packages were to be built-in?
A $158) 8:
Word Processor
File Manager
Spreadsheet

Memo Pad
Telecommunications Package
Q $159) In the Commodore LCD unit, what were the text screen dimensions?
A $159) 80 coumns by 16 rows. 1200 characters on screen.
Q $15A) What is the version number of the only known "bug-free" VIC-II
IC?
A $15A) 6569-R5. What's funny is that this chip was manufactured after
the Commodore 128 was introduced, so they used the 6569-R3 for the
development of the Vic-IIe chip (8563 series), which is buggy.
So, the newest PAL 64s have a better VIC than the C128.
Q $15B) Machine language programmer typically use the .X register to index
into small arrays. What is the largest byte-array size that can be
handled in this way?
A $15B) 256 bytes.

One of the models had a name which was a type of horse. Name the term.
A $15C) The Commodore "Colt" PC.
Q $15D) What is the model number of the first mouse introduced for the
Commodore 64?
A $15D) The 1350.
Q $15E) What was the problem with the mouse in question $15D?
A $15E) As Commodore was either still developing the (now more
popular) 1351 mouse or the 1350 was designed as a lower cost
alternative, this mouse could only emulate a joystick. When you
rolled it up, the joystick "UP" pin was triggered. Likewise for the
other directions.
Q $15F) If you hold down the cursor key on the CBM 4000 series machine and it
does not repeat, what fact about the machine do you now know?
(other than the key doesn't repeat)
A $15F) It is a thin 40XX machine, meaning it could not be upgraded to an
80XX machine via chip swaps.
