Re: Getting files off a 7300--Mission accomplished
Hm. Then I have a dillema. When I popped in the Miniscribe and tried booting it started reading the disk then popped out a boot error. Possibly a bad sector, but how can I read this disk to find the rest of the data? Hm Anyone got one of those Beaglebone/RPI to MFM readers I could borrow for a bit to slurp this drive?

The ethernet_hardware_diag.dd is bad. The files are in multiple locations on this site but any 10S image thats not 404480 is bad.

Re: Getting files off a 7300--Mission accomplished
That could be helpful. There seems to be a need for it (at least one), and it's going to take awhile to sift thorough everything to find all the disks. Also I'm wondering if this system had a 70mb disk originally and was replaced with a 40mb disk from another 7300. That could explain why the TCP drivers are not on it, they might be on a crashed disk somewhere in that pile of stuff. Dig we must...

Re: Getting files off a 7300--Mission accomplished
It did not seem to work and ping from the command line was not found. So it might not be on there. That said I picked up a bunch of manuals and one of them was on TCP for the 7300 (red ATT manual). Maybe some floppy disks in there. I'll also keep an eye out for loose 5.25 floppies if this is that rare (have focused on 8 inch as they seem to be the ones for the Perqs) C On 7/20/2020 4:20 AM, Al Kossow via cctalk wrote: On 7/19/20 12:42 PM, Chris Zach via cctalk wrote: Now I have a big crate with "Convergent technologies" sitting in my truck, I'll have to figure that one out next.

Re: Getting files off a 7300--Mission accomplished
Thanks David, and everyone else for helping me with getting these files off. Starting on Friday I hooked up a serial cable and null modem to my laptop PC, got getty running, and logged into this 7300 as install. Escalated to root and went over to his directory. The big problem is the system did not have kermit but it *did* come with an XModem like program that I could hook up to with a simple Xmodem protocol on the PC. Uploaded Kermit, and sure enough it works... From there it was a matter of copying the files and . files in his home directory, then tarring and compressing the big directories. This let me know just how far we had come: It would take 10+ minutes to compress a 6mb tar file, but when I decompressed it on my Mac Mini it would take well under a second. We have come a long way... After moving all the files and directories I patted the computer on the top of the monitor and said to it "Well Done, though good and faithful servant" then did a rm -r on the rdd directory. Now I can put it up for sale and give the money to his mom. Today I went over to her house with a 40 page folder of some of his writings. Bob was among other things an amazing author, and the items on this computer spanned his life from 1986 to about 1993. She was very happy to see his writings and poems, in a way it gave her a chance to get to know him again even after all these years Now I have a big crate with "Convergent technologies" sitting in my truck, I'll have to figure that one out next. Also more Perq manuals and floppy disks. It's never a dull moment. But it's nice I was able to use my forensics skills to bring an old friend to life again...

I thought the UnixPC kernel/drivers were smart enough to automatically detect the serial card(s) in any slot, but it's been almost thirty years since I dealt with that, so perhaps I'm misremembering. The built-in serial port is one port of an NEC uPD7201 (or Intel 8274) at a fixed address, so the driver for that should always be present.
Re: Getting files off a 7300
You might be able to use a terminal to pull/push files via the serial port. Log in using the "install" user (password = blank/none) and work your way to the Hardware setup window. From there find the RS232 section and if necessary change NONE to TERMINAL. With a null modem adapter plug a serial 9600/N/1. Worth a try. b On Tue, Jul 14, 2020 at 9:01 AM Patrick Finnegan via cctalk < cctalk@classiccmp.org> wrote: > This gets my vote too. > > Pat > > On Tue, Jul 14, 2020 at 3:00 AM Ian Finder via cctalk < > cctalk@classiccmp.org> > wrote: > > > David Gesswein's excellent MFM emulator will capture a full-fidelity > image > > of the disk- both flux and bits- if you want the ultimate possible > archival > > integrity: > > https://www.pdp8.net/mfm/mfm.shtml > > > > Every vintage computing household needs at least one. > > > > On Mon, Jul 13, 2020 at 11:39 PM Grant Taylor via cctalk < > > cctalk@classiccmp.org> wrote: > > > > > On 7/13/20 9:12 PM, Phil Budne via cctalk wrote: > > > > UUCP? > > > > > > I'm glad that someone else said UUCP.
