There might be others, but these we can confirm. There are 9 if you count the 1541-II board as a 1541 board, 8 if not. 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?

(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.

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. Q $15C) In the mid-1980's, Commodore started manufacturing IBM clone PCs. 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.
