- Subject: HD-DOS+
-
- Just wanted to let everyone know
- that the new HD-DOS+ is close to being
- ready and is just one more thing to
- look forward to at the upcoming EXPO
- in May.
-
- If all goes well over the next two
- months, HD-DOS+ should be ready to
- ship to those who have pre-ordered it
- and also to those who have purchased a
- new CMD-HD since August 2001. It will
- be installed into all new CMD-HD's
- that are built once it's completed.
-
- From the way it looks, the only
- way it might not be ready to ship at
- EXPO time is if there are any bugs in
- the system. And even if that is the
- case, I plan to put on a good
- presentation of the new system at the
- EXPO.
-
- Here's a brief rundown of the new
- features:
-
- * Native partitions operate a little
- faster.
-
- * Built-in print spooler is
- functional. The HD watches for data
- being sent to device 4 (or 5) and
- captures the data to a PRINTER
- partition and while data is still
- coming in, it gets spooled out to
- the printer or printer interface
- attached to the AUXILIARY port on
- the back of the HD. The HD can
- capture the data much faster than
- most printers can. Even while data
- is still being sent to the printer,
- the HD can be accessed normally for
- loading and saving, etc.
-
- * New features are implemented to aid
- programmers in accessing SCSI
- devices attached to the system.
-
- * Two new partition types are added.
- Extended Native partitions and
- Extended Foreign partitions.
- Extended native partitions can be up
- to 4gb in size and include features
- that help new software operate more
- efficiently. Extended foreign
- partitions can be up to 8gb in size
- and are designed mainly for data
- storage that does not require a file
- system.
-
- * As for the maximum size of SCSI
- mechanism allowed, nobody makes one
- that big yet.
-
- * There is a reserved 2048 byte
- buffer in memory for future CD-ROM
- usage. Or for software that needs a
- large buffer.
-
- * Disk images are supported. For
- instance, you can copy as many D64
- images into an Extended native
- partition as you like and be able to
- access any of them as though they
- were a real partition. A D64 image
- can be attached to an existing 1541
- partition. It will remain there
- until the drive is reset and then
- the original partition will once
- again be visible there. You can do
- this for as many partitions as you'd
- like up to the maximum of 254. You
- can store thousands of image files
- into an extended native partition.
- Over 23,000 D64 files will fit into
- a 4gb partition. D71, D81, and FD
- disk images are also supported.
-
- * We've always been able to select a
- partition from the front panel
- switches, but there is also a new
- combination you can use. Press and
- hold the SWAP 9 button to move to
- the next partition or press and hold
- the SWAP 8 button to move to the
- previous partition. This feature
- allows you to have two or more disk
- image files visible in adjacent
- partitions and perform the same
- operation as if you were to switch
- disks in a real 1541.
-
-
- The new system includes a new rom
- module that looks like a 1541 JiffyDOS
- rom with a switch. This allows you to
- use either the new HD-DOS+ or the last
- one that CMD introduced. The
- installation utility will install both
- software versions onto the hard disk
- without losing any existing data in
- your partitions. An original HD
- Utilities disk is included along with
- a new disk with new utilities
- specifically for the new HD-DOS+. It
- also includes a manual supplement to
- go along your existing HD manual.
-
- Hope to see everyone at the EXPO
- on Memorial Day weekend.
