I need another operational HP 7970E mag tape controller (13183 - 2 board set). It appears that the spare board sets I have are 13181 which I believe is only for the 7970A/B. All my drives are 7970E, so is there any chance someone has a 7970A/B but has a 13183 and would like to swap my 13181 for it? J Or if anyone has a spare 13183 they want to sell/trade... Best, J
