- uTape Transfer
- Introduction
-
- Almost all of the Commodore 8 bit
- computers have a Datassette
- connection. The only exceptions I can
- think of are the C64 Games System and
- it's successor the C64 DTV. The
- Datassette was a cheap alternative to
- the diskdrive and was sold by the
- millions. Most (budget) games for the
- C64 were sold on tape.
-
- So you have a great collection of
- original tapes or made programs
- yourself on tape and want to use them
- on an emulator. This page will
- describe how it is possible to read
- the tapes into your modern PC. You
- need to build (or buy) a interface
- that connects an original Datassette
- to your PC.
-
- Specifications This are the
- specifications I personally use to
- transfer my tape's. Any PC will do
- that can run MS-DOS and has parallel
- port and a floppy. PC: Pentium III,
- 256 MByte, 4 GB HD OS: MS-DOS 6.2 +
- Windows 2000 SP4

- Software: MTAP + PTAP: Markus

- Hardware: C64S interface 1530

- Disclaimer: Every thing you will do is
- on your own risk. I have made a great
- effort to get the info on this page
- right but there could be a mistake on
- this page that I am not aware of. If
- you find an error please let me know
- The interface
-
- First you will have to build yourself
- a C64S interface. It's not very
- difficult to build. This interface
- will give you a Datassette and a IEC
- (diskdrive) connection. You can see
- the schematics bellow. The interface
- needs a regulated powersupply of
- exactly 5 volts DC to power the
- Datassette. There are a few ways to
- connect a power supply, choose one of
- the following.
-
- It can be done by a external power
- adapter and a voltage regulator as is
- shown in the top left corner of the
- schematic. The external powersupply
- can be anything from about 9 volts to
- about 24 volts AC or DC. The regulator
- will make a perfect 5 VDC voltage.
- Another way of getting the 5 VDC is by
- connecting the interface to the
- gameport of the PC this is shown at
- the top right corner of the schematic.
-
- The way I did it is to make a
- connection to the PC powersupply
- directly. I did this because my PC
- didn't have a gameport. You can see
- the connection bellow. After soldering
- the wire be sure to isolate the
- connection with isolation tape.
-
- In a PC the red wire is the 5 volt DC,
- but to be sure test the voltage. Use a
- rubber grommit where the wire leaves
- the PC housing to prevent damage to
- the wire. On the photo bellow you can
- see my first version of the C64S
- interface.
-
- Instead of a connector were you can
- plug in a IEC cable I connected a IEC
- connector that plugs into the
- diskdrive (top). From a piece of PCB I
- made a Datassette connector. I made
- cuts with a junior saw in the copper
- layer. And made the notch in the PCB.
- Use a PCB with only copper on the top
- side. After that I soldered all the
- wires to the connectors. Put some
- insolation tape on the PCB for the
- Datassette were the wires are
- soldered. Don't forget the connection
- in the D25 connector between 2 and 15.
- If you can't make the interface
- yourself take a look at the website of
- Markus Brenner. There is a link to
- order a complete interface.
-
- The PC. The software that is used for
- the transfer is written for MS-DOS so
- you won't need a state of the art PC
- to do this. I had an spare Pentium III
- 600 MHz, a couple of 2 GB HD, a CD-ROM
- and this is perfect for the job. I
- installed Windows 2000 on the second
- hardisk (D:).
-
- So you have access to an emulator
- like VICE os CCS64, zip, internet and
- much more. But Windows 2000 can't do
- MS-DOS. After installing everything I
- installed MS-DOS 6.2 on the first
- harddisk (C:). After doing this the PC
- will boot to MS-DOS. Don't panic about
- the Windows 2000 part. Put in the
- installation CD of Windows 2000 and
- preform a repair of the system. When
- you now boot the PC it will ask which
- operating system to start (Double
- boot). Don't forget to format your
- harddisk(s) with FAT. If you use NTSF
- you can't use MS-DOS. Go to the
- website of Markus Brenner and download
- MTAP (Read tape's) and PTAP (Write
- tape's) unzip the programs on the
- MS-DOS part of the harddisk. After
- this you have to get hold of a little
- program called CSDPMI.EXE and put this
- in the same directory as MTAP and
- PTAP. If you don't have CSDPMI.EXE try
- Google.
-
- Shut down your PC and connect the C64S
- interface and a Dattassette to the
- interface. Boot the PC to MS-DOS and
- go to the directory with MTAP. Start
- the program MTAP.EXE. The program will
- list all possibilities. If you use the
- C64S interface connected to the LPT1
- port the command is very simple:
- mtap.exe game.tap [ENTER]
-
- The program will check if the
- interface is connected and ask to
- PRESS PLAY ON TAPE. If you press play
- on tape the program will record the
- data from the Datassette to a .tap
- file named game in the same directory
- as MTAP.EXE. With very big tape's such
- as compilations you need to increase
- the buffersize. On the photo above you
- can see the program in action. The
- border of the screen will show lots of
- colors while recording the data. After
- all the data is recorded to the
- harddisk reboot the PC to Windows. And
- start your emulator and load the
- game.tap file. On the photo's above
- you can see the emulator in action.
- The very cool wallpaper is from Ingo
- Ruhnke aka Grumbel.

- The program FinalTap from Subchrist
-
- http://www.coder.pwp.blueyonder.co.uk/
- software can be used to scan the
- imported .tap file. It will identify
- the speedloader and can export the
- program to a .prg file. Also it can be
- used to repair a .tap file.
-
- If you want to write a .tap file back
- to a tape you can use the PTAP
- program. For the users of the 264
- series of Commodore computers there is
- a special interface available. Source
