Is that because it's using memory in the low 64k? Is there any reason a GS version couldn't be placed in a higher memory bank?

I've had no probelm with P8 device drivers on the GS as long as they are allocated in higher memory banks. Is the memory space on a 6502 system what you are referring to as the Prodos driver problem?

I was primarily thinking of using it to copy data from OS X to my HD after each build, so I don't need much memory.


I did a quick test using a USB serial connection between OS X & the GS via ADT Pro VSDrive.2.0.1.

Copy II+ was able to access the virtual drives in s2 like a normal Prodos volume and copy files between my HD & the virtual volume.

One odd thing though is that Prodos had already assigned s2d1 & s2d2 to my other devices at boot. When I ran VSDrive, it grabbed slot 2 and overrode the existing mappings, but also added 2 more volumes.

Here is my Copy II+ device list prior to installing VSDrive:

S3D2: /RAM DISCONNECTED
S5D1: 3.5" d1
S5D2: /RAM5
S2D1: 3.5" d2
S4D1: /HD1
S4D2: /HD2
S1D1: /HD3
S1D2: /HD4
S2D2: /HD5
S7D1: /HD6
S7D2: /HD7
S6D1: 5.25" d1
S6D2: 5.25" d2

And after running VSDrive:

S2D2: /VIRTUAL2
S2D1: /VIRTUAL
S3D2: /RAM DISCONNECTED
S5D1: 3.5" d1
S5D2: /RAM5
S2D1: /VIRTUAL
S4D1: /HD1
S4D2: /HD2
S1D1: /HD3
S1D2: /HD4
S2D2: /VIRTUAL2
S7D1: /HD6
S7D2: /HD7
S6D1: 5.25" d1
S6D2: 5.25" d2

So now the 2 virtual drives are mapped to 4 slot/drive devices, displacing the 2nd 3.5" & the 5th HD partition. It's also showing 15 mounted Prodos volumes when the max is 14. I haven't seen that before.

Bredon's Cat Doctor (Prosel8 utility) crashes with vsdrive installed.

Apple's ProDOS filer utilities seems to work fine with vsdrive and will catalog, copy files, etc.

Looks promising, particularly with ethernet instead of serial and a GS driver.
