How to load ADVENT on PDP-8?

by djg＠pdp8.net

Not sure if this was resolved. I think the adventure on the diagpack2.rk05 was built for running off a floppy. It will not run directly from the rk05 image. The one on this image will run directly from it with RUN RKB0:ADVENT ftp://ftp.pdp8.net/images/os8/diag-games-kermit.rk05 It was built without EAE since my EAE wasn't working right at the time so should work on any machine. If you wish to put adventure on a different image/media follow these instructions http://www.pdp8.net/pdp8cgi/os8_html/ADVENT.DC?act=file;fn=images/os8/diag-… Start from the EXECUTION step since the files needed for the earlier steps no longer exist. If you are moving between an emulator and a real PDP-8 make sure that you disable things like EAE when building that you don't have on the real PDP-8.

Building M8027 hookup

by millercmp＠keyways.com

Here is a pinout for making a cable to connect an M8027 module to a standard Centronics 36 pin connector. We have used this cable on many of our in-house RT-11 systems and Epson-style printers. In addition to being a DEC dealer, we are a hobbyist in the areas of RT-11, OpenVMS, Oregon Software Pascal-2. Thanks. Mitch Miller Keyways, Inc.

Cromemco software available

by doc＠mdrconsult.com

Does anybody have a working Cromemco with 5.25" SSSD floppy drive[s]? I finally made it out to pick up my Z-2D, and it came with a lot of floppy diskettes. As it's going to be awhile before I bring up the Z-2D to boot - it hasn't been powered up in many years, so I'll be cleaning and then powering it up in stages - I thought I'd go ahead and image the diskettes. I've spot-checked a couple with 22Disk and they seem to have valid data, so I'm going to try my hand at Dave Dunfield's ImageDisk. I'd like for someone with a working system to try the images and see if they're bootable. Some of the diskette labels are totally incomprehensible to me, but here's a list (almost all hand-labeled): Cromemco CDOS SYSTEM DISK Cromemco 16K BASIC Cromemco Z-2D Test Disk 1 OF 2 CDOS 1.7 & Gen.

I'll be looking to suck the data off that soon, too, if it's alive. Doc

IRIX (Was RE: besl Linux distro)

by compoobah＠valleyimplants.com

Unfortunately, it seems that the end of IRIX is creeping closer- I was just poking around on the SGI website and it looks like they've dropped the big MIPS graphic systems (Onyxes) Linux is a fine system, but IRIX is very nice, too, and it's nice to have multiple sources of ideas to draw from (Indigo Magic is a pretty slick desktop, among other things SGI did.) The big advantage of Linux over xBSD looks to be filesystems- Linux has JFS and XFS. P.S.- I do know about 5dwm.org, and I look forward to seeing it.

But they and >a lot of the rest of us know that's really one of the only things >they have going for themselves. Therin lies the truth of the matter. It's why the VAX11/780 happend, DGs machine Eclipse, and many others. The investment of software and the desire for "customer retention" are often drivers of technology choices. Its basic to even chipsets be they 8080 to 8088 then on to 80286 and Motorola did the same with 6800, 6809 and 68K. Granted in many cases at the chip level they are not binary compatable the idea being everyone gets to keep what they learned and has an upgrade path. I don't think for one second that was missed in business 101. However, legacy can be an albatross, ones neck may be on the line if the choice is wrong. Allison

Notice that I didn't say "CP/M-86", which >uses int 224 to make system calls (which will not work under MS-DOS or >Windows of any flavor). I suspect this is an artifact of old SC-DOS/QDOS. And it works on W98 too. I know for a fact that old DOS DBASEII used it along with FCB support (another CP/Mism) with one caveat, the target drive or partition have to be less tha 500mb! I know because I was running a job costing system in DBASEII on a PIII running W98se and that was the trick. Allison
