2800 HD (250-3550) Memory Management Under 1 Meg Faxback Doc. # 16794 The Tandy 2800 system has 1 meg of internal memory. Only 640K of this memory is available to the sandard MS-DOS operating system. The memory can be accessed and used as a RAM-Disk with the VDISK command: DEVICE=VDISK.SYS 384 /A Where VDISK.SYS is in the root directory. If VDISK.SYS is in the DOS directory, your statement would look like this: DEVICE=C:\DOS\VDISK.SYS 384 /A This will give you a 384K RAM-drive as drive D: if you add it as a line in your CONFIG.SYS file.
