I have 30 "older" IBM machines in my lab and three 486s. The older
ones are 8088s and 80286s.
You will need hard disks in the computers. First if you locate a reseller of
computers, look for leasing operations, they will sell "junk" CPUs for $15
each.
All of the junk older CPUs have hard disks, install hard disks in your
computers.
The same recycler will sell CGA and EGA monitors for $10, keyboards for $5.
You will have to invest some time, but most "as is computers" can be
made operational for total cost of about $50-$65.
We use the program Microsoft Works Version 3.0 for DOS. We have 125
copies and they cost $17 each with an educational discount. The DOS
version uses the same, menu bar system and commands as the Windows
version, so there is easy (or easier) transition to newer computers.
Works includes a very good wordprocessor, telecommunications, spreadsheet, and
database program.
Computer shopper has single speed CD-ROM drives for about $27.00.
This can be installed and then wonderful, CD_ROMs of sharewhare
programs can be perused with 10,000s of programs. These programs
include math programs, quiz maker programs, crossword puzzle makers,
tutorials, "print shop" type programs and lots and lots of games. Also if you
have any local BBSs they usually have lots of DOS software online.
On 80286s a 3.5" drive can be installed, a 3.5" drive can be
installed on a 8088, but you will need a driver. It is good to have
at least one machine with a 3.5" drive and a 5.25 inch drive, so you
can copy programs from one format to another.
We use manual 4 position printer switch boxes (cost was $8 from
computer shopper) , and have one printer for four machines.
Just an aside, these older computers are great for learning
"keyboarding." Several parents have donated "older" computers as
they know we are using them.
