$230) What control character would one send to a Commodore printer
to start double-wide character printing?
|
On the 1525 (and successors, like MPS 801, MPS 803, etc), chr$(14)
was used. A few IEEE printers also contained chr$(1), which printed
'enhanced' double wide characters.

$232) What control character would one send to a Commodore printer to
end double-wide character printing?
|
On the 1525 (and successors, like the MPS 801 and 803), chr$(15) was
used. On the IEEE printers and the 1526/MPS 802 (a 4023 IEEE printer
with serial bus connection, chr$(129) was used instead.

$233) How many registers does the VIC-I (6560/61) IC possess?
|
According to Commodore, the 6560/1 IC contains 16 addressable control
registers, which is the number we were looking for. How many registers
are actually used internally is anyone's guess. We also accepted 26
as the answer, since there are 26 differint configuration fields
within the 16 bytes of memory mapped I/O.

$234) How many registers does the Plus/4 TED IC have?
|
Multiple answers exist for this question as well. The TED contains
addressing to support 64 I/O registers, but only 34 are used.

$236) If a program opens a channel to tape, reads some data, and a check
of ST AND 32 is true, what error does that indicate?

$237) Depending on how many memory was added to a VIC-20, BASIC could
start in one of three locations. Name them.

$239) If one sees a directory listing that starts with:
"MY DISK OF STUFF,MY,2C" What CBM drives could have wrote this
disk?
|
8050 or 8250 or derivatives: 8250LP and SFD 1001.

$23A) Name a color available on the VIC-20 that is NOT available on the 64?
|
Any of the following qualify:
o Light Orange
o Light Cyan
o Light Purple
o Light Yellow
By the way, none of these colors can be used for text.

$23B) Name two CBM computer series that used a real 6551 UART to do
serial communications.
|
The Plus/4, the B128, The 700 Series. I suspect the 600 and 500
Series as well.

$23C) On the Commodore SX-64, is drive 0 above or below the built-in
storage bin?
|
It is below the storage bin. For those who created a DX-64 (2
drives, the standard placement is to instal Drive 1 above drive 0.

$23D) Without looking, which key is located to the direct right of the
semicolon ';' key on the C64?
|
With exception to the Swedish 64, The equals '=' sign. On Swedish
models, the return key sits next to the ';' key. On Swedish
keyboards, the key placement of the rightmost 4 columns is altered.

$23E) What does drive error number 72 mean?

Disk Full or Directory Full

$23F) What was the model number of the first serial drive Commodore
developed?
|
Technically, the 1010 was the first unit, but I have no reports
it ever made it past prototype stage. And I doubt it was serial.
The 2040 would qualify, but it was parallel (IEEE 488). Therefore,
the VIC 1540 is the first CBM drive to fit the criteria.
