The vintage of the driver appears to be roughly 1/84. It is the one distributed by Adage on their AIDS tape. We have a relatively new ik11 board which the field service people apparently know only as "the latest rev". It was reputed to have a fix to some communications problem but in fact *seems* to have made things worse for us. The problem is that we can reproducably hang the kernel in one of several annoying ways by interrupting a program which is doing a transfer to(/from ?) the Ikonas. I've written to rdg about it and he had not heard of the problem. I suspect a timing problem between the the vax and the 3000, perhaps a side-effect of the vax's 750ness (as opposed to 780ness). So I ask you: 1) Does anybody else have a 750 with an RDS-3000 that does or does not manifest this problem? 2) Has anybody seen this before on any machine with an RDS-3000? 3) Does anybody else have the mysterious "latest rev" of the ik11? Does it work? 4) Does anybody else get *answers* to this sort of question from Adage? George W. Sherouse Radiation Oncology North Carolina Memorial Hospital Chapel Hill, NC 27514 (919) 966-1101
