Two ESDI drives available

by kelly＠catcorner.org

Well, I've made up my mind. Actually, I found a controller for these drives and have installed them in a computer I use to emulate the old Tandy's I collect. How's that... Emulating a 20 year old computer on a 10 year old computer with 15 year old hard drives. Now, on to the next question. I need a 34 conductor flat cable with male IDC on one end and socket on the other. Anyone know of a good source for these? Thanks, kelly -----Original Message----- From: Kelly Leavitt [mailto:CCTalk@catcorner.org] Sent: Thursday, March 27, 2003 6:29 PM To: 'cctalk(a)classiccmp.org' Subject: Two ESDI drives available I have two: Imprimis 94166-182 (150 MB) Maxtor XT-4170E (170MB) Any one need them? I collect mostly old Tandy stuff. Model II, 12, 16, 6000 is my main focus. Any interesting uses for these boat anchors? Thanks, Kelly

Victor Keyboard Identification

by thosmm＠yahoo.com

Rob, It's an enhanced keyboard from a Victor 9000 system. They were built in the early 80's and were pretty good machines. 80 track 5.25" disks held 1.6MB and ran CP/M-86 or MS-DOS. 800x400 graphics mode, although most were monochrome. You can also see them labeled as Sirius machines from time to time.

H89 CP/M hard-secored boot diskette

Since it is a standalone, I don't know how one could easily transfer it with HDOS. Still, I think I can come up with a simple serial to disk boot strap that would allow one to dump it from a PC onto the H89 disk, through the serial port of the H89. I've done this for several other processor ( like my Poly88 for tape images and my IMSAI to bring it back to life ). It has been a long time since I've looked at the disk EPROM's access methods. I'm sure I can figure it out and get something going. That way you could save the disk as an image file and all one would have to do is enter a small boot strap program from the monitor to get it going. I've always felt that this was the way you should be maintaining the library since it is simpler than sending media around the world. It does require that the machine in question have a code monitor or possibly a location to install a bootstrapping EPROM at worst. In any case, it would be good to get my Forth and the HDOS stuff I have transferred to something that can be easily distributed. Dwight > >> It has been a while since I had the machine running.

Gernsback Publishing closing

by RCini＠congressfinancial.com

Hello, all: I just got my latest copy of Nuts & Volts last night and to my surprise, there's a note from Larry Steckler of Gernsback, the publisher of Radio-Electronics and Popular Electronics (merged into Poptronics). He says in the note that Gernsback Publishing is closing after 94 years and N&V will be fulfilling the balance of the subscriptions. I pass this on to the list with mixed emotions. For many years I subscribed to both R-E and PE but once I found Nuts & Volts, I did not renew either subscription. They strayed too far from the content I liked and N&V had some interesting regular columns -- Amateur Robotics and BASIC Stamps -- that more closely followed my interests. I had the same feeling when Byte, well, bought it, in 1995 -- a formerly great publishing that lost its way and its relevance to its core readership. Rich ========================== Richard A.

software mentioned in March

by xtguy＠mindspring.com

Last month, someone mentioned some old software they had found in an old house. Listed among the items was a copy of Word Perfect 3.0 for DOS. I've been trying to find that for a while and if it's still available, I'd be interested. I'm also trying to find a copy of Word Perfect 2.0 for DOS, and a copy of Wordstar 2x for CP/M. Thanks.

There you type "abo at." at. is the indirect task executes the startup.cmd file. If you'r luckey, you have now an open console that is also priviledged. If you're unluckey then a smart sysadmin may however have build some precautions into the startup.cmd file to prevent this to happen. Frank

I have a Victor 9000 (a.k.a. 'Sirius') with a keyboard that looks identical to that. (just joined the list a couple of days ago.) Kevin

Z-Star 433 VL info/parts

by jmaranon＠ing.unlp.edu.ar

Hello Ray: I've got one notebook like that you have. I think is difficult to run win95 in this machine, because it has 2 Mb RAM memory, but if you get about 10 Mb RAM more you can run win95. I haven't got the battery pack, maybe you can build one buying the adecuate batteries. But, now, I am asking something to you. Do you have the owner manual of the machine (better if you have an archive with this and the technical information)? The machine that I have is not working and I am looking for technical information. thanks, Julio
