1050 happy drive chips?

[E474]

Hi,

 

   The manuals are on archive.org -> https://archive.org/search.php?query=1050 duplicator 

 

   There's also a lot of info at : http://www.realdos.net/1050 Duplicator.html

 

   It looks like there is software for the Revision 3.0 board, images of both Front and Back of the utility disks (among others).

Happy 1050 Controller:

 

https://archive.org/details/Happy1050ControllerInstallationAndUsageInstructions
 

The LED on the CONTROLLER turns on and glows yellow whenever disk writing is enabled. This is a cautionary signal. It is suggested that you enable writing only when you actually intend to write.

 

The following information is for CONTROLLERS that have the original factory jumpers installed. The lower three position switch on the CONTROLLER provides manual control of the disk drive write protect system. The normal disk drive write protect sensing system works as usual with this switch in the NORMAL lower position. Disk writing is inhibited whether or not there is a notch in the disk when this switch is in the center PROTECT position Disk writing is enabled regardless of disk notch when the switch is in the upper WRITE position This allows formatting and writing to the disk back side without punching holes in the disk. Please note that some lower quality disks may not work on the backside, especially in medium or true double density It is necessary that you manually turn the disk over to use the back side. If a software command is issued to protect or unprotect, this command overrides the switch position and the diskette notch sensing system. The technical section of the software instructions rev 7 or later describes these commands These features are also available on the DRIVE PROGRAM OPTIONS MENU when you boot the WARP SPEED SOFTWARE and select item 1.

 

The upper two position switch of the CONTROLLER is the SLOW/FAST switch. With the two position switch in the lower position the ENHANCEMENT is in the normal fast buffered reading mode. With the two position switch in the upper position non-buffered (slow) operation is selected. Normally except as described below to enable fast writing, the only time you need to select slow mode is to boot a copy protected disk that will not boot in the fast reading mode that the HAPPY is in when you first turn the drive on. Please note that SLOW mode is not the same as UNHAPPY mode. In slow mode selected by the switch the HAPPY is still programable by the computer; slow mode has no effect on the HAPPY backup program The only way to completely lock out the HAPPY features is through the UNHAPPY mode selection of the WARP SPEED SOFTWARE, and this is usually not necessary.

Awesome information, thanks!

The header is indeed normally "intended" for a happy controller as @ratwell indicated. In the particular drive pictured above, there is a small modification: The controller header is used as a source of +5V, which is used to switch power to either the ROM on the happy board, or the original 1050 ROM on the 1050 motherboard. Both have pin 28 lifted and connected to the wire from the switch.

Oh, ok, thanks for the information.  Mine was actually setup with a modified version of 1/2 controller board...   It does the write protect but not the speed.
