This page covers the modern hardware which can be used to replace Floppy Drives in a real TRS-80.
|HxC Floppy Drive Replacement for a REAL Model I/III/4|
The SDCard HxC Floppy Emulator designed by Jean-François Del Nero, emulates a 34 pin floppy drive and treats DSK and DMK images which are stored on a SD card as actually floppy disks. To be clear, this product is designed to be mounted in/on an actual TRS-80, as a drive on the floppy cable.
It can emulate one or two drives, and disk images are mounted using the three buttons on the lower right, which are NEXT, SELECT/EJECT, and PREVIOUS. The filenames are shown on the LCD, which comes in a variety of colors.
Current features of the SDCard HxC Floppy Emulator are:
|SVD Floppy Drive Replacement for a REAL Model I/III/4|
Eric Rothfus has developed a hardware device called the SVD (Semi-Virtual Diskette) which is a device which emulates a floppy drive.
The SVD connects to the serial port of a PC and to the floppy drive cable on your TRS-80, download a floppy image to the SVD, and then boot that image on an actual TRS-80 as if that floppy was actually in the TRS-80′s drive.
The SVD is actually bi-directional, so you can also save from the TRS-80 onto the PC.
The SVD is based upon a PIC micro-controller along with some memory. It listens to the floppy control signals from the TRS-80 and generates the appropriate signals back, so the TRS-80 believes that it is attached to a real floppy drive. It attaches to a PC through a standard serial port, operating between 9600 and 115200 baud. Through programs running on your PC, you down/up-load the SVD and control its operation. The PC interface includes capability to read/write “standard” diskette formats.
Current features of the SVD are:
You can get more information on the main SVD page found at http://www.thesvd.com/svd/index.php. That site is VERY VERY detailed.
