Someone just dropped off a mac g3 at the scrapyard I work at and I picked it up. It has a failing hard drive. Replaced the drive, downloaded and burned a disk with mac os 8 on it, but it refuses to boot to it. How do I go about installing the software on this machine? Not sure if this is the place to ask, but figured it would be worth a shot. Thanks.

DR-DOS

by lproven＠gmail.com

I hope this is vintage enough. I've been playing around some more with my projects to create VMs / bootable USB keys with PC DOS 7.1 and DR-DOS. Right now I'm focusing on DR-DOS 7.1 and the DR OpenDOS Enhancement Project, because that's FOSS and AFAICS it can be redistributed, which I can't with DR-DOS 7.02/7.03/7.04/7.05 or DR-DOS 8/8.1, which were commercially licensed. I found a download of the last build released: https://archiveos.org/drdos/ First, it's the wrong size. VirtualBox can't mount it. VMware can. I truncated it to exactly 2880 sectors using the advice from ``jleg094'' here: https://forums.virtualbox.org/viewtopic.php?f=4&t=39141 VBox mounts that. But it won't boot, nor in VMware -- it just displays 2 dots and freezes. Embarrassingly late in the troubleshooting process, I've found why. I didn't think to check what was on the image! Foolish of me. I mounted it on a pre-booted VM and looked, and it's blank! There's nothing in the image at all. So, I mounted the empty image file as a loop device, copied the boot files in there and then the rest of the files in the distro archive. And lo, it works! It boots my VM just fine, and it's now running 7.01-08. All I need to do now is work out how to make the hard disk bootable, and I'm in business. The DR-DOS 7 SYS command won't do it, as the files aren't named IBMBIOS.COM and IBMSYS.COM -- they're DRBIO.SYS and DRSYS.SYS. I copied them to the expected names. SYS completes but the disk won't boot. Next step will be to try with Norton Disk Doctor. Anyway, if anyone wants a bootable diskette image with DR-DOS 7.01-08, complete with FAT32 support -- apparently it can even boot from it -- let me know. -- Liam Proven ?

All I want for Christmas is an RK8E

by chd＠chdickman.com

About 15 years ago I told my girlfriend I wanted an RX8E controller board for Christmas. I was curious how far she might go to get it for me. I ended up with two packages: one from her 8 year old daughter with a bit of 1x8 pine plank (If he wants a board, I'll get him a board!), the other package was an M8357 that she probably paid way to much for... Now the girlfriend is my wife and the daughter is getting married. This Christmas I am asking for an RK8E. I doubt it can be found at a reseller. So does anyone have or know of an OMNIBUS RK8E boardset they are willing to part with? This is an M7104, M7105, and M7106 along with 4 over-the-top edge connector blocks. I have two RK05 drives for a PDP-11, but my goal is to build an RK05 emulator based on Dave Gesswein's ST506 disk emulator. Merry Christmas, -chuck

TI 99/4a It Lives! but extended basic? acts bizzare...Help?

by COURYHOUSE＠aol.com

TI 99/4a It Lives! but extended basic? acts bizarre... Great got the video cable 5 bucks from the UK - -SOLVED! Works and fires up with out the extended basic plugged in but when I pluged it in and selected the option for extended basic at book up just hangs no prompt on screen etc. I have the screed that TI had that was more of an industrial display rather than the screen that was converted TV that may have been earlier.. Heavy little monitor! It has a strong mesh looking internal mask on the screen compared to modern color CRTS/ We also have a Epson looking printer with TI logo to pair up The goal of course is to set up as a display at SMECC Museum with some of the other micros where it can be demo'ed I have the speech module too but have no idea what to do with that. Have a disc with cable but need some sort of an expansion to plug it in. The adventure continues... as always drop any ideas hits etc to us/// Learning as we go As I never used or sold any of these when in the biz back then!

Canon BN22 Laptop manual, anyone?

by binarydinosaurs＠gmail.com

Hi folks, I?ve been contacted by someone looking for the user guide for this particular beast, an early 90s mono laptop with built-in printer. The usual searches turn up nothing other than pictures and she says she?s found a PDF but in German. Any clues? ? Adrian/Witchy Binary Dinosaurs - Celebrating Computing History from 1972 onwards

Dec-10 Day announcement from Living Computers: Museum + Labs

by jnc＠mercury.lcs.mit.edu

> From: Ethan Dicks > I look forward to taking a stab at this. I suspect there are a number of people who'd be interested in MASSBUS storage devices (e.g. me - suddenly all those RH11's I've got are no longer boat- anchors :-). We should try and organize an group build, to share the load. Anyone else interested? Oh, one detail I didn't look at: what's the physical interface this uses? Hopefully three of the Berg/DuPont connectors (i.e. what's on the RHxx boards, with flat cables going to the adapter to the standard MASSBUS connector, a device rejoicing in the name 'Receptacle Housing Assembly'); the original MASSBUS cables (along with the 'Receptacle Housing Assembly' are now rare as hen's teeth). And there's also the MASSBUS termination... Noel
