Oh!! A PCjr question! Oh oh!!! A stock PC keyboard will not hook up to the Jr because the Jr is, well goofy. There is a technical description behind goofy and I can take an hour to paraphrase the technical reference manual, but not right now ... You have three options: [1] Find a real PCjr keyboard, either the original chiclet or the improved keyboard. These show up on (gasp) ebay once in a while, without the rest of the computer. [2] Find a pseudo-real PCjr keyboard - Keytronic made some really nice keyboards and numeric keypads for the PCjr. [3] Find an adapter. Several companies made these, but I think they are very rare. I've never seen one, and I'm sure that not many were sold. Good luck. PCjrs are wonderful little machines. Here is my contribution to classic computing: http://pws.chartermi.net/~mbbrutman/PCjr/ Mike PS: The gun discussion is rediculous. Please stop. Wading through the digest is hard enough. Wading through it when half the messages are about gun control and life vs. death situations is even more difficult. A newsgroup or discussion list probably is not a good place to discuss this, especially a discussion list dedicated to classic computers!

Need help with retrieving data from a DOS 2.11 formated floppy disk

by jtsai＠vortek.com

Hi everyone: I need help to solve a problem. Could anyone lends a hand? The company I work for has a machine that runs on DOS 2.11 There are some data on that machine that we need to retrieve. The information is transfered from that old machine to a 1.44mb floppy. When we put the floppy into our pentium winNT4 computer , we can not read the information on the floppy. The NT os simply says it does not know what format the files are at. Now do I need to install a dos 2.11 or is there anyway around it ? What is the format the dos2.11 writing its files in? Are there any program that reads in that type of format? Does any one here have DOS 2.11 that I can download? Even if I do have DOS 2.11, will I be able to install it or do I need very old hardware as well? Jimmy Tsai SFU engineering 3rd year

A good shell for ProDOS

by RCini＠congressfinancial.com

Hello, all: I've got my Diamond TrackStar working well now and have worked out most of the kinks. So, I'm playing around with the supported ProDOS volumes (two 10mb volumes). I'm running ProDOS 1.1.1. I still have to copy either 1.9 or 2.0.3 to the volume from various floppies that I have. Anyway, what's a good shell for ProDOS? I have Sneeze running, but there seems to be a problem with it recognizing the volume (maybe it's an issue with running 1.1.1), so I see no volumes on the screen. Rich

Dissed by DSSI

by jeff.kaneko＠juno.com

To everyone who responded: The DSSI adapter has been spoken for. The other adapter was some brand-x thing that I haven't identified yet (I *thought* it was DSSI, but it definitely isnt . . .)

Multi-Z80 system design

by kebabthesheep＠yahoo.com

Hi all, When going through my stash of older ICs, I identified about four complete Z80 chipsets, and well as many perhipheral devices. For some pervese idea I have decided it would be fun to get back into hardware and software co-design. I intend to construct a multi-z80 machine, based upon a plane backplane, identical cpu cards, and perhipheral cards. I will also design an RTOS for this or port a unix. I have most of the information I require, except for data on the Z80 DMA and CTC. The only files I can find on the web are a two page summary from Zilog, and a large and very broken datasheet from Farnell. Does anybody have any (digital) copies of the datasheets I could copy? I'll tease for now, until I have made a few more design decisions, and decided exactly how I intend to pull this stunt off. Details to follow - should be loads of fun :) Many thanks, Dave. ____________________________________________________________ Do You Yahoo!?

The thing that struck me about SDI was the *square* coaxial wiring they used. Wierd. I've seen alot of SDI's (mostly in little pieces), but never a DSSI (I just made some wild assumptions about DEC hardware :^).
