Ok, from what you've said about the monitors, their EHT sections work
(that's what the 'static' you hear is - the EHT starting up). What
particular type are the monitors? If they're old Hitachi HM-4119's, you
will have trouble keeping them going since this is a very old model. I
have a broken one here which cost me about A$150 to have fixed, but then
it failed again so I've abandoned it for now.

I presume the machines have cg3 colour framebuffers in them?  Setting
location 0x1F in the EEPROM to 0x12 should work, but you might like to try
setting that location to 0x20 instead.

The ESDI disk(s) will be attached to Emulex MD-21 ESDI-SCSI converter
boards. The MD-21 supports up to two ESDI devices. The first drive will be
sd0, and the second one will appear as sd1 if any of the shoeboxes have
two drives instead of just one. 

The tape drive in each shoebox will be attached to an Emulex MT-02
QIC-SCSI converter. The two common tape drive types Sun used are the
Wangtek 5099 and the Archive 5945C. The MT-02 is normally set to SCSI ID
4. 

If you have access to a SunOS 4.1.1 boot tape, you should be able to use 
some of the default drive format and partition table entries to configure 
the disk(s). The 'suninstall' program (run from the miniroot after it's 
loaded and booted from) takes you through all the steps.

Regards,

Craig.
