A customer of ours has to buy an industrial PC for shop-floor debugging of control systems. They have to buy an industrial model, so recommending just buying a Dell or a Compaq would not be helpful. For various reasons, some of the tools used by the customer are best run under true DOS rather than a DOS box under NT / 2000. Some of the DOS tools are old fashioned in that they do not support any type of DOS extender or even EMS and run only in the 640K area -- requiring an aggressive memory manager to free up as much low memory as possible. They need the following: - Must be able to support an external keyboard, or preferably, have a 100+ keyboard built in so that they can use the older S5 software with the number pad keys [! CP/M ! ] - Must be able to support DOS with a memory manager (a lot of machines with the new fancy BIOSs lock up after the memory manager is installed with enough UMBs freed up to make it worthwhile OR a lot of machines have weird memory assignments in the upper memory blocks to make memory management useless) -- this also really means being able to turn off advanced features such as automatic power management since it may lock up DOS - Also support Windows NT / Windows 2000 - PCI connectors - ISA connectors for legacy interface cards I would appreciate any feedback. We are located in Canada. Regards, RJ
