From: CHARM::SYSTEM
To: @SYS$MAIL:ENGINEER
The current Charm is actually one of the new Vaxen. It doesn't have ANY disks of its own. Instead, it is using GAWD's system disk for system, page and swap files. CHARM$USERDISK is located on Kim, so Kim does the file serving for Charm's userdisk. It may crash because DEC says the system can't be hooked up like this, but I did it anyway. You will know if they were right. For some things, you may notice that this system is about 3 times faster than the old Charm. However, since it does its page and swap access via Ethernet, it may slow down quite a bit for other things. Also, it won't run MAC65, the BSO assembler or TECO. I believe that the 780 Charm's system disk has some kind of problem which has been the reason for 780's crashes recently. I dual-ported Charm's disk controller last weekend so that you could get to the userdisk even if Charm was down. As it happens, the problem in the system disk seemed to cause both Kim and Charm to crash, so it has been disconnected. A 780 won't work without a system disk which is why I tried hooking things up this way. Perhaps by tuesday the disk will have been fixed and I can put things back to normal. dms
