I have an operational H/Z-110 low profile computer with the Zenith Color monitor. Unit has dual hard drives and a floppy installed internally. MB is the last revision produced and has 768K loaded. The optional Gemini card to run PCDOS (IBM) native programs is also installed. Outboard Zenith 8" floppy drive in the factory enclosure. Original User Manuals, Technical Manuals and Service Manual set with all service bulletins included. ZDOS, MSDOS version 2, CP/M-80, CP/M-86 operating systems. Several applications software items including Wordstar, Multiplan, Condor, and others (15 original 3 ring binder documentation sets) and other user software totalling over 200 5.25" disks. $150 for the whole lot. Pick up in the St. Louis area. I need to get this system out of the way and into a new home for someone to use. Help! Thanks Mike Stover, Florissant, MO

iOpener

This now appears when you begin a purchase transaction on the Netpliance web site. By purchasing the i-opener you are agreeing to use the i-opener Internet service. The fee is $21.95 a month and will be billed to your credit card approximately 2 days after the i-opener is shipped to you. i-opener Internet appliances shipped after March 20, 2000 can no longer be reconfigured in the manner described in recent reports. Modification of the i-opener in any way is in violation of our terms and conditions. >From: Brian Roth <broth(a)heathers.stdio.com> >Reply-To: classiccmp(a)classiccmp.org >To: classiccmp(a)classiccmp.org >Subject: Re: iOpener >Date: Fri, 24 Mar 2000 22:29:30 -0500 > >Its possible that they could goo the area with epoxy which will make it >very >difficult but not impossible to add the drive.

Do you have this archived: PDP-1 source code. PDP-11 source code - Dos/Batch-11 , RT11. I also have source code to most of the packages they released. If you have this stuff then I won't bother archiving all the source code I have and pass it on.

IC ID help needed

by ethan_dicks＠yahoo.com

I've done the basic digging (www.chipdir.com, etc.) and can't find info on the following chips I found in a box of stuff some one gave me a while back: AMD 91L02 - I know it's some kind of SRAM but not the size or pinout. The 9101 is 256x4. This one is likely to be either 1024x1 or 1024x4 but I don't know which. NS 74C921 - The 74C922 and 74C923 are somewhat common keyboard encoders, one of which was used on the Netronics Elf-II design. I can't find any info on the pinout of the 74C921, but I did find several places selling them from $6 USD to 72 Danish Kroner (however much that is) I have a few of each, along with 2Kb of 21L02 chips (-2L and -4L speeds, whatever they are), all with 1979 - 1983 date codes. Any clues? Thanks, -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away. The permanent home is: http://penguincentral.com/ See http://ohio.voyager.net/ for details. __________________________________________________ Do You Yahoo!? Talk to your friends online with Yahoo!

Qbus cards that need ID

by Innfogra＠aol.com

I have four Qbus cards that I am interested in finding out what they are. One is a Micro Technology QTS25. It has a 50 pin header. I was wondering if it was a SCSI card? The second is an Emulex QD331040100 Rev. J. This has a 60 pin header and two 26 pin headers. I was wondering if this was a SMD drive controller? The third is a Dilog DQ696-20.vThis has a 34 pin header and two 20 pin header. My guess is that it is a MFM or ESDI hard drive controller. In the same group of cards is a DEC M7546 which I believe is a TK50 tape drive controller. Why is it called a Maya Controller? Thanks for the help. Paxton

I believe that Maya was the DEC development code-name for the TK50.

I need some PDP-11 RT11 archiving software

They're fairly different "inside". For example, kermit assumes an "unreliable" connection, and does it's own error-checking, while FTP relies to some extent on a transport layer that already has error-checking. I suppose they naturally have some similarities on the "outside" because they serve similar purposes, though. Anyway, kermit predates FTP by a few years. -- Pete Peter Turnbull Dept. of Computer Science University of York
