A number of experimenters at the Advanced Photon Source 
have been using the OMS VME58-8 since I have been here
(1/98) without any major problems.

Of course, there are always changes.

Support for the OMS VME58-8 extends back to at least
Motor Record version 2.3; I don't know if any earlier
versions of the Motor Record supported the VME58.

The differences between the "oms" and "oms58" device
drivers are minor in terms of the "st.cmd" file.  Simply
add an additional setup line for the "oms58" as follows,
	

# OMS VME driver setup parameters: 
#     (1)cards, (2)axes per card, (3)base address(short, 16-byte
boundary), 
#     (4)interrupt vector (0=disable or  64 - 255), (5)interrupt level
(1 - 6),
#     (6)motor task polling rate (min=1Hz,max=60Hz)
omsSetup(5, 8, 0xFC00, 180, 5, 10)

# OMS VME58 driver setup parameters: 
#     (1)cards, (2)axes per card, (3)base address(short, 4k boundary), 
#     (4)interrupt vector (0=disable or  64 - 255), (5)interrupt level
(1 - 6),
#     (6)motor task polling rate (min=1Hz,max=60Hz)
oms58Setup(5, 8, 0x3000, 190, 5, 10)


Please be aware that there are some known problems with
earlier Motor Record releases (i.e., anything before
Version 3.4).  See below for problem description,

As long as we are on the topic of OMS VME58 boards;
Attention anyone out there with OMS VME58-8S boards.
				-------------------
OMS has upgraded EPROM U78 to BV52.2-8S.  This
fixes a bug that caused the VME58-8S board to be
unavailable on the VME bus every other time after
a VMEbus System Reset.
