Programming on metal cylinders?
I was assisting an older client the other day, a former Yale prof, and he's been programming since the late 1950s. He knew people who worked at Bletchley Park. He also mentioned he knew people who had manually scribed their programs on some sort of metal cylinder. Which computer system was that? Part of what he'd like me to help with is a circa 2001 Compaq / DIGITAL version of a FORTRAN programming environment. He had not yet found the installation media so we could try to get it running on Windows 10. I wonder if it will... - John

Made a clone of the floppy with a SuperCard Pro board and it IMLs far enough that I can get into some diagnostics. Don't know what to do without docs. I suspect the configuration goes through the RS-232 port, since all of the configuration string are in ASCII. Today's project is to go through the later-gen 1174 controller docs to see if there is some hint of how to configure the thing and try that on the earlier model.

If by "masthead" you mean the thing DEC calls a "Logo Panel" (see 11/70 Engineering Drawings, 'Unit Assembly', pg 1 of 5), it's the same as all the other PDP-11 etc logo panels, the -11/70 just has an inlay (thin metal sheet) which is painted differently. And yes, there's a 5mm gap between the top of the top 10-1/2" blank panel, and the bottom edge of the logo panel. Noel

'Same physical shape' is what I meant; just different stuff painted on the insert. > thanks for the confirmation. Sure, glad to help. Noel

Cool, do you happen to have schematics for the keyboard or a description of the signaling? I could help make a hardware convertor that takes in a USB keyboard and spit out DW keystrokes... A POST logic trace would be helpful I'm sure - where are you located? We can take this off-list if you prefer. =] -- Anders Nelson +1 (517) 775-6129 www.erogear.com On Sun, Apr 21, 2019 at 12:24 PM Al Kossow via cctalk wrote: > > > On 4/20/19 3:47 PM, Anders Nelson via cctalk wrote: > > I haven't found any more info on the signaling that goes > > over the DB37 data cable, and I would like to use my portable logic > > analyzer to sniff out some basics: > > I could help you, I have several DWs and I want to document the hardware, > but thanks to kb vultures I've not been able to find a complete keyboard. > I have the PCB and cable but none of the mechanical parts. > > I guess I could try hooking that up to try to get past POST. > >

Looks like this guy has the Displaywriter keyboard protocol on his to-do list: http://www.kbdbabel.org/ -- Anders Nelson +1 (517) 775-6129 www.erogear.com On Sun, Apr 21, 2019 at 10:15 PM Anders Nelson wrote: > Cool, do you happen to have schematics for the keyboard or a description > of the signaling?
