I’m remembering them being connected to terminals and microcomputers (HP 150, HP Vectra PC) at 9600 bps and needing some sort of flow control. I am thinking there was a jumper on the serial I/O board that needed to be set just so. And yes, they are mostly Diablo 630 printers. They’re nice daisywheel printers. Loud enough that HP sold an enclosure. Fancy enough that HP sold a simple tractor feed kit and a fancy cut-sheet feed unit with two input bins. The enclosure was big enough for either. -Frank McConnell

Re: Hewlett Packard 2601A Printer
I have an old daisy wheel printer by Hewlett-Packard, their 2601A. We got this from an estate cleanout and I would like to sell it. It has been powered up and the power light comes on and the carriage moves to the starting position. It is a large, very heavy machine. I have it on ebay for $150 (https://www.ebay.com/itm/223533138720) but that was just a shot in the dark. There is a better description and more pictures in the listing.

During the nominal cycle the address, then strobe, then data (from ot to an addresses device or memory) and controls asserted for the cycle type (ReadWord, Read ByteHigh, ReadbyteLOW, WriteWORD and so on. There are also transfers on the same lines for interrupt vector and priority. All that makes the BDAL lines busy... Generally the LSI-11 is a bit stranger as it also does bus level memory refresh for dynamic ram card that do not refresh themselves. The contemporary memory cards did not self refresh and used the early 4K or 16K 16pin devices. Memory used for 11/23 (f11) and later by then self refresh on the local card level was the norm and cut bus traffic load. Many of the functions were replicated as part of the T-11 CPU. > I'm going to look into that more, to try and understand what I'm seeing there, > but it won't be today, which is 'crane day'!

Nobody in a PDP11 is interested what Windows thinks about partitions. Most of the PDP11 SCSI Controllers could build two or more PDP11 disks out of one physical device. That is what I meant with partition in this case, if you dind'nt like it, call it slice. There is some logical information on the device, you simply don't get the entire raw device on the pdp as you possibly think. Shure, you can write to the entire disk on an PC with some tools, but what you write has to fit the CQD220 adapters idea how the data structure has to be if you would boot that. Tapes have no such restrictions, that's why I suggested using a tape. Regard's Holm -- Technik Service u.

Could the issue here be something as simple as a > break in the qbus due to a misplaced board? He did mention that he had the console card in the slot next to the CPU, which I think is what you're referring to - but it shouldn't matter for ODT, which doesn't use interrupts, only programmed I/O. A QBUS system will work fine without continuity of grant (interrupt, DMA) lines to boards which only respond to DATI/DATO (memory, non-interrupt I/O, etc). Just for grins, I took my -11/03, and plugged the console card in a bunch of slots down, leaving several empty slots between it and the CPU, and it worked 'fine': ODT was fine, and it would run "BR ." programs fine, too. So unless there's actually a break in one of the 'broadcast' bus lines (e.g. BDALxx, etc) on that backplane, between the CPU slot, and the slot the console card is in, or something like that... I suppose it would be worth while checking BDALn, BSYNC and BDIN _on the console card_ (I'm not sure where he was looking at them, before) just to rule out the broken bus line possibility. One thing that's bugging me, though; he said "BDAL3-13 .. are all active and jump around in some manner". But for the ODT microcode loop trying to read the console CSR, i.e. 0177560, BDAL7 (0200) and BDAL3 (010) should be 0, i.e. un-asserted. So why are they jumping around too? Is this somehow related to the odd behaviour I was seeing on my machine with no console card, where the BDAL line was behaving in a way I couldn't understand? I'm going to look into that more, to try and understand what I'm seeing there, but it won't be today, which is 'crane day'! Noel
