[comp.sys.cbm] C64 IEEE-488 9090 Harddisk

bjh@cbnewsj.ATT.COM (bernard.j.hudson) (02/14/90)

Maybe this is digging up the past, but I am experimenting with
IEEE-488 interfaces to the C64 for disk drives.  I need help.
I am aware of the following interfaces:

Interface   Maker          Load+   Save+   Features
---------   -----          ----    ----    --------
BuscardII   BatteriesIncl   27      27     Cart pass-thru, printer,device switches
G-Link      Transactor      13      11     * Serial/IEEE488 switch, no passthru
MSD CEI     MSD              ?       ?     ** Cart Pass-thru                 
Quicksilver Skyles       ***fast    fast   C64 and C128/64 versions (ROM change)


+   BASIC LOAD and SAVE on C64 and a fresh 9090 Harddrive: 99 blk PRG file
*   How do I access the serial-bus devices when in IEEE mode ? Switching modes
    often causes a lockup. A Serial <-> IEEE copy program is available.
**  What SYS to enable the MSD interface?  Does it work with non-MSD drives?
*** What is the speed of this interface ? Does it work with FLASH! ?
    Do any co-exist with a serial-bus drive Speedup (FastLoad, JDOS) ?

Does anyone have a Quicksilver for sale  cheap ?
After I have my fun, does anyone want to buy a 9090 7.5M harddrive ?
(How do I change (hardware or software) the device number on a 9090 ?)

Help/comments ?                  ....BJ   att!mtgzz!bjh
