If you look straight down, with the handles at the top, the card with the
23-243E5 and 23-244E5 ROMs has a pair of jumpers to to the right of the
ROMs. These aren't on the cards I've got with the 23-216E5 and 23-217E5
ROMs, nor are they on the documentation that Bruce Lane provided last
weekend.

The card with the later ROMs will in fact support my home made RX33's. I
pulled all the cards out of the chassis tonite and stuck in a /23+ some RAM
and the late model RQDX3, and was able to boot off of floppy. I was also
able to boot off of the RX50 drive.

However, no matter what I try I can't get them to work when the ESDI
controller is in place. On that note I'm giving up on this line of attack
at least for the time being.

Thanks to the information that Megan and Tim provided on partitioning a
drive I've just finished that. I took Tim's advice and went with the hard
partitioning. Assuming I can find enough time tomorrow I will bring the
RL02 drive into the house, play swap the RLV12 and transfer everything from
the one system to the other that way.
