The HxC Floppy Drive Emulator is a software and hardware system created by jfdn aka Jeff.
The aim of this project is to replace the floppy disk drive by an electronic device emulating the floppy disk drive (list of supported Computer/Hardware).
There are two differents emulators:
- A USB version which allows to connect the floppy disk drive interface of the computer to a PC via a USB cable.
- A SDCARD version which allows to emulate floppy disks which images are stored in a SDCARD.
Release notes for the HxCFloppyEmulator software v2.0.26.0:
- New Loader : PC Magazine (FLP) file format support added.
- GUI – Track viewer window : Track editing functionality added, internal sanity check added.
- libhxcfe : Casio FZF loader -> non sector-aligned file image size issue corrected.
- libhxcfe : Generic flux stream analyzer enhanced – Track encoding & RPM correctly reported.
- Batch converter : Now use the folder name for the output filename while converting KF stream files (raw).
- FAT12 Disk Browser: PC98 FAT disk support enhanced, free space reporting corrected.
- Raw Loader – Predefined raw formats added (XML) :
- Logical Interchange Format (LIF) 3″1/2 264KB (single side).
- Logical Interchange Format (LIF) 3″1/2 616KB (double side).
- Logical Interchange Format (LIF) 3″1/2 1232KB (HD).
- Logical Interchange Format (LIF) 5″1/4 264KB.

The Tandy Radio Shack TRS-80 DT-1 is a video terminal. It is ideally suited for communications with the TRS-80 Model 16 Multi-User Office System or with other host computers. With a low-cost Tandy acoustic coupler it can also access time-sharing information networks.

State-of-the-Art Design:
Unlike many terminals, you can easily set up and change the configuration on your DT-1 from the keyboard. A revolutionary non-volatile memory that retains your terminal configuration even with power off and without battery backup!
Multiple Emulation Modes:
The DT-1 is completely code compatible with four standard terminal protocols.
- Televideo 910
- Lear Siegler ADM-5
- ADDS 25
- Hazeltine 1410
The 30.5 cm diagonal CRT displays 24 lines of 80 upper and lower case characters per line. Special single-character symbols are used to display control characters.
Dual-Speed Repeat:
Any character can be repeated by merely holding down the desired key. After several characters are repeated, the DT-1 will automatically repeat the characters at a faster rate.
Two Printer Ports:
The TRS-80 DT-1 can be equipped for hardcopy output by connecting a printer to the built-in RS-232C serial interface or parallel interface.
Special Features:
A local monitor mode lets you enable printer ports and position the cursor using local control and escape modes. The carrige return key can be programmed with or without a line feed. Control key termination codes are also user programmable. An electronic bell is standard.
TRS-80 DT-1 Highlights:
- Data Transfer: 75,110,150,300,600,1200,2400,4800,9600,19200
- Cursor: Four keyboard-selectable types: Steady, Blinking Block, Steady or Blinking Underline.
- Video Attributes: Normal, reverse, Invisible, Blink, Underline and Half-Intensity Video.

Defects:
- Some keys are dead (X – Z – DEL – ])
- Sometimes the characters typed are uppercase and sometimes lowercase.
- The DT1 Terminal doesn’t turn on the first try.
- Horizontal scan problem. The right side of the image is rolled up on itself.
- Outside ground of the CRT disconnected.
The jobs that have been made:
- Replaced 1 x 74LS138 Demultiplexer (U1)
- Replaced 1 x 74LS240 Octal Buffer/Line Driver (U23)
- Replaced almost all capacitors on the power supply side with the wrong ESR/Capacitance.
- Cleaning keyboard switches. Fortunately these switches can be opened.
- Removed the filter capacitor (RIFA)
- CRT Linearity adjustment.
- Restored the outside ground of the CRT.
