- in the uuencoded .lzh archive which I'll send in my next mail message.

- A VIRTUAL DEVICE DRIVER FOR THE AMIGA
- or "THE POOR MANS FLOPTICAL"
-
- ALPHA APRIL 15th 1991
- By Anselm Hook
-
- Its amazing that the Amiga is 5 yrs old and yet still has the best
- operating system on the market. We all know that the Amiga supports a true
- multitasking operating system. But the real proof of the pudding is the
- fact that its extensible. The customer supported open architecture of the
- Amiga Enviroment makes it possible for me to extend the functionality of
- the entire system. The Virtual Device is in this sense, made possible by
- the excellence and forethought that went into the design of the OS.
-
- Matt Dillion wrote the original File System on which this one is
- based.
-
- The Virtual Device is simply another path on your system, like RAM:
- (except its called VIR:)....you can copy files to and from it like a RAM disk,
- and like a RAM disk all files are lost when you power off. But what you
- can also do, which you cannot do with a RAM disk is not copy a file, but just
- aquire a virtual reference to that files real location. This way the VIR:
- device can appear to have hundreds of megabytes of files online, but in fact
- it actually goes out and retrieves them from where they are really stored
- (sometimes prompting you to insert a disk). So it acts as a *transparent*
- disk manager as well. You can access VIR: from anywhere, from SID, from DPAINT,
- from anyplace you can access any other device (like RAM:, DF0: etc...).
-
- This is only an Alpha Version, there is no load save facility (although
- I have a version here which is struggling to do that). I will be upgrading.
-
- What I want at this point is to get feedback, inspiration, suggestions,
- and any assistance that you may be willing to provide.
-
- I can be reached on the AMUC VBBS in Calgary.
