TASM for Windows

Author: Borland
Email: None
Website: http://www.borland.com/
Released: Feb 20 1996
Platform: Windows
Source: www.phatcode.net
Binaries: Yes

Summary:

Turbo Assembler 5 is the last version of the popular assembler by Borland, with both DOS and Windows assemblers.

TASM has full 8088, 8086, 80286, 80386, i486, and Pentium support, as well as interface support for C, C++, Pascal, FORTRAN, and COBOL. A full-screen interactive debugger (Turbo Debugger) is also included.

The download below includes the original install disks for TASM 5.0, along with patches to upgrade to version 5.3.

Note: TASM is no longer sold or supported by Borland. Therefore, I am making it available for download here. If you represent Borland and want this download removed, please contact me.

To get TASM version 5 for 32-bit windows, link on the below link!

DOWNLOAD TASM 5.0 (32-bit)

(Total size: 5.2MB)

Steps to install TASM for 32-bit:
1) On unzipping the files you'll get a folder named tasm5 which will have the folders:
DISK1
DISK2
DISK3
DOCS
PATCHES
phatcode

2) Copy contents of DISK2 AND DISK3 in the DISK1 folder.
2) Copy the entire tasm5 folder to C:
3) Open folder DISK1 and Run "INSTALL.EXE" as administrator. Press Enter
4) Enter the source drive to use: C
5) Press Enter, it will show you the path for installation.
6) Press Enter and select start installation.
7) It will ask if you wish to create groups and icons, click yes.
8) Congratulations! You're done!

Oh, ignore the rest of the files. TASM 5.3 patch is also available. If you can install it, well and good but it's totally unnecessary.

Steps to install TASM 64-bit:

1. Go to Start, and My Computer. Click on (C:) Local Disk C (or any desired location you want).

2. On the directory, create a folder and name it TASM ( or any name you want). 

3. Download THIS file.

4. Extract the contents of the .zip file.

5. Copy the extracted files to the folder TASM (or to the folder you've made awhile ago). Also, don't forget to extract the DEBUG125.zip to the same folder.

6. Download DOSBOX HERE

8. After installing the DOSBox, run it and type the following lines:

MOUNT E C:\TASM    
E:


If you chose a while ago a custom drive besides the directory of C:

LET X be your drive letter:

MOUNT E X:\TASM
E:

9.Done!!

If nothing works then take the file from me in college via Bluetooth :-P
