From 9f7a66a7a20518b4caadeea4171b2652c82eb839 Mon Sep 17 00:00:00 2001 From: Mark Pizzolato Date: Thu, 17 Dec 2015 06:38:31 -0800 Subject: [PATCH] PDP11: Fix Unibus boot of RSX-11M+ systems from RQ devices The RSX-11M+ boot driver expects a slower response from the simulated UDA50 controller. This response is only in during the MSCP initialization sequence, so normal protocol interactions for read and write I/O are unchanged. Updated value determined by John Forcast. Fixes #216. --- PDP11/pdp11_rq.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/PDP11/pdp11_rq.c b/PDP11/pdp11_rq.c index fe641db2..f0962a9c 100644 --- a/PDP11/pdp11_rq.c +++ b/PDP11/pdp11_rq.c @@ -754,7 +754,7 @@ static struct ctlrtyp ctlr_tab[] = { extern int32 int_req[IPL_HLVL]; -int32 rq_itime = 200; /* init time, except */ +int32 rq_itime = 450; /* init time, except */ int32 rq_itime4 = 10; /* stage 4 */ int32 rq_qtime = RQ_QTIME; /* queue time */ int32 rq_xtime = RQ_XTIME; /* transfer time */
