$111) At one time, Commodore attempted to manufacture a dual drive
version of the 1571 called the 1572. For what technical reason
did it utimately fail?
|
One must remember that the 1571 DOS was a descendant of the 1540
DOS, which was in turn a descendant of the earlier dual drive IEEE
drives. To make the 1572, Commodore engineers tried to re-introduce
the dual drive code that had been removed when Commodore started
producing single disk drives. Unfortunately, the re-introduction
did not ultimately succeed.

$112) Over what computer system did a User Group sue Commodore and win?
|
The Commodore B-128 line. Story has it that the B-128 User's Group
sued Commodore because they claimed to support the B-128 after CBM
had closed down production of the B series. The suit demanded that
all materials needed in manufacturing and supporting the machine was
to be handed over to the User's Group. This included masks of the
ICs, source code for BASIC and DOS, and schematics.

$113) In $103, the question asked how to create a graphic of a small box
on the 1525. In this quesrtion, we have made a different design.
If you wanted to create the following graphic using individual
dots on the printer, what bytes would you send to the printer after
turning on graphics mode?
** * *
* ***
* ** ***
* * * * *

$116) What is the alternate name for the Commodore 65?
|
Some versions of the prototype C65 are referred to as the Commodore
64DX.
|
| Top |
$117) How many processors does the internal 1581-compatible drive
on the C65 contain?
|
none. This is interesting, as Commodore started with two CPUs per
drive (IEEE 8050, etc), went to 1 (1540, etc.), and finally cost
reduced the CPU completely out of the drive electronics.

$11D) What CBM disk drive DOS was used as the template for the internal
C65 drive DOS?
|
The Internal DOS in the C65 was based on DOS 2.7, found on the
CBM IEEE 8250 Drive. This DOS was adapted to the Commodore 65
by Dennis Jarvis.
