I am interested in any information that people would have concerning network workstations. I am adding to a network for a small business. They are interested in purchasing 4 extra workstations. Since this is for use in a non-technical environment, they don't need or want a whole lot. Basically, the people using the 4 workstations will be using them to post transactions to a RealWorld Database. The base machine I am interested in is as follows: 286-12 with 1 meg of ram, 1.2meg 5-1/4" floppy with hercules graphics. The questions I have are follows: 1) Do you think a hard disk (even a small one) is necessary? 2) Is a floppy drive even needed, or should I look into diskless workstations? 3) What companies might you recommend. The business I am dealing with wants to spend as little as possible. (They spent good money on the server and have a Dell workstation currently.) In a case like this would you risk going with the lowest price (since if one goes down its not a GREAT loss)? 4) What experience do people have dealing with the RealWorld Software Package, specifically Version 5 for networks. (They are upgrading to this from a single station version 4.) 5) One of the machines will be in the warehouse section. This means it will be subject to smoke (this is a smokehouse) and grease from fingers when typing. What steps should be take to protect it? Thanks in advance for any information that people may have. I will post a summary of information if people are interested. Greg_d._Moore@mts.rpi.edu

It is certainly worth taking a look at Novell. You can set up a machine as a server, and connect all the wrkstations to it. You would ideally need a large fast hard disk on the server. The workstations then need only have a floppy drive so as to boot them up. There is no need to have hard disks on the workstations. With this configuartion you could have for example 4 XT workstations and a 286 server with say, a hard disk with access time of 20mS. You would find this more than adequate. A good database to use in a network environment is Borland's Paradox 3.0. -- ------------------------------------------------------------------------------- jagrogan@vax1.tcd.ie@cunyvm.cuny.edu ----------- --- jagrogan@vax1.tcd.ie / / / / jagrogan@unix1.tcd.ie ---- ---- / / jagrogan@maths.tcd.ie / / ------ / / jagrogan@tcdmath.uucp / / / / / ------- /--------- jagrogan@lanczos.tcd.ie -- / / / / / ---- / / ---- / --------------------------- / / / / / / / / / / / / 3rd Year Computer Science ------ ------ --- --- --- --- Trinity College, Dublin. --------------------------- "I haven't lost my mind.....I'm sure it's backed up here somewhere!"

Well, most Ethernet (and many ARCNET) cards allow a boot-prom to be installed. This means you can remove (or not buy) floppy drives/controller, install the boot prom, tell the server about them (and install DOS), and boot without the floppy at all. It will save power (and thus heat), prevent employees from installing unwanted/untested software, prevent the removal of sensitive data by floppy (they can still print it), and maybe save some money. The proms are about twenty to fifty dollars U.S. and are EASY to install. They boot MUCH faster and don't wear-out like floppies can. We use them in educational networks where we can boot 100 workstations in the time 10 booted with floppies. This strongly limits what the students can do to 'crack' the network and prevents the theft of courseware. ---- James Wyatt (KA5VJL) - Standard disclaimer applies...

Keep in mind that new chips must be installed with any software upgrade, whereas with floppies one only need cut a new boot disk) They are faster, and save the expense of providing boot floppies. As far as security with boot proms, since our LANs are on a backbone network and users can FTP software in and out of the file server scratch space anyway, we saw no advantage to removing the floppy drives, and the disadvantage of a lot more user hastle. Our newest site has 50 IBM PS/2 model 55sx machines w/30 meg hard drives. The hard drives are the boot device. For security the file server erases all files off the local hard disk with every login. Hope this helps, John. ---------------------------------------- John Early | jearly@lehi3b15.csee.lehigh.edu | I was just a child then; JPE1@Lehigh.Bitnet | now I'm only a man.
