which 8" drive are most likely to work w/a stock high density controller?

by rampaginggreenhulk＠yahoo.com

one other question - shouldn't it be relatively easy to write a program that recognizes another IBM pseudo compatible's MS-DOS format? If for instance you wanted to read NEC APC disks on a Canon AS-100. The Leading Edge Model M (fully peecee s/w compatible) tech ref manual states it not only can use quads but 8" drives. I forget the specifics, but it has an 8272/NEC pd765 (so does the NEC APC. Funny that the aftermarket board/5 1/4" drive set that I have for it uses a WD chip).

Cambridge Digital 11/73 system questions

by jplist2008＠kiwigeek.com

Greetings; I have a Cambridge Digital "94/23-70S" that I'm trying to bring back to the land of the living, filled with cards I can find little information about. I was hoping someone might be able to point me in the right direction. QBus cardcage with: Chrislin Industries CI-1173-EDC Emulex SU0210401 Technical Magic Inc 4S I think it's fairly clear the Chrislin is an 11/73 SBC, I know the Emulex is an SMD controller, and the 4S is a four-port serial card. I can't find manuals on either the Chrislin or the Emulex, and although I can't find a manual specifically for the 4S 4-port serial card, BitSavers has one for its bigger brother - the 8S 8-port card. Hopefully they're close enough. System also comes with a CPI tape drive (BY5A3-B) and an 8" Fujitsu M2312K. I'd really like some PSU pinouts so I can test it prior to plugging the cardcage in and seeing if it works. The boards are also covered in a fairly thick layer of mold, which is something I'm not used to seeing. Trying to decide what I can use to safely clean them - possibly Isopropyl, a QTip and some patience. Any help would be greatly appreciated; - JP

Reading Floppies

by cool1＠thecoolbears.org

Hey Everybody, Is there anybody in the San Francisco Bay Area that could create images of three 5.25" floppies for me? I think that they are 720k with 256 byte sectors, but I'm not sure. In any case, I've not been able to read them so far.

>>> I'd be curious to see any examples of prior art. >> Although not exactly the same, Kay's "Dynabook" concept would surely be closely related prior art. No, I meant prior art of clamshell designs. If I wanted merely prior art of a laptop computer, then there commercial examples before the Compass, such as the Husky Hunter (1981). Beside, and as you noted, Dynabook is only a concept. Not to insult PARC, but you might as well have cited something from Star Trek.

DOS era chatterbot nonsense-generator

by dgriffi＠cs.csubak.edu

I'm trying to remember and locate a chatterbot program from the heyday of DOS. I think it was called "jabber". What made it particularly interesting is that you could feed three text files of stuff (like novels, scientific papers, etc) and then control the proportions of how much of each input file made it to the output. When all were set to zero, it would just emit "jabber" over and over. Google isn't particularly helpful in finding this. I'm getting false hits on the Jabber IM protocol and denial of service attacks. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?

Kaypro PC ? == Micro 1

by dflowers＠gmail.com

I don't know if anyone is still interested in this. I have a Kaypro Micro1 with monitor and keyboard. It has a 10 MB hard drive and runs on MS DOS 5.0 and Windows 3.1. It has 2 3.5" floppy drives. I've never seen another one anyplace. Dave

68k Mac diagnostics?

by fraveydank＠gmail.com

Hello all, I have a Quadra 700 which I've mentioned before which is in a poor state. I've finally gotten it to power on with a replaced power supply, but it dies with the chimes of death at various points before and after the boot chime; it never appears to initialize the video. I'm aware that the Q700 is quite reliant on the monitor sense pins, so I'm using an Apple 12" RGB monitor that I've verified working on an Apple IIgs. Since I can't see any video (there is no activity on any of the pins on the monitor port, not even sync pins), I'm wondering if there's another diagnostic tool that can be used aside from building something to hook into the '040 PDS and attach to a logic analyzer. I suppose it would be too much to hope that it can be made to spit something out on a serial port? The fact that the chimes come at different points in the process, and that it seems to change when I poke things on the board, leads me to believe it may be beyond help, but if there's something simple I can do to check it out, I'd be glad to. I've already tried swapping out for a known-good '040 and removed all the RAM (so it runs on internal RAM) to no avail. - Dave
