Re: pdp11/84 PMI memory: What is the problem with Q bus?

Oh I'm using an MTI MQD13 card as my disk controller. It is a MCSP controller that can interface up to 4 ESDI drives to Q Bus. Pretty fast. Just checked the configuration and block mode DMA *is* off. Wonder what happens if I turn it on... It does have a lot of knobs to fiddle with, so maybe I

Sorry about the uNOTE confusion...  I was focused and just used the reference from the OEM version.  I was aware but had mentally excluded the older Microcomputer Products Group/Components Group version. If you look at the Memory Comparison table in this OEM uNOTE, it only lists Block Mode for

Oh, right. Still, it sounds from reports here like regular DMA doesn't work in QBUS mode either - and technically that table entry might mean than since it doesn't work for the QBUS _at all_, that includes no block mode. Regular Q bus DMA seems to be working fine. I can see the performance diff
