Honeywell tps 3000 dcs system

Sir,

we have honeywell dcs system(tps 3000) since 2004.
Hardwares using in the GUS were obsolete and not available in the open market. It couldn't be rectified and informed by OEM . They recommend to go for upgradation.
Major issues in TPS are following:
1) Integrated key board not available.
how to convert qwerty keyboard inplace of IKB.
2) Which model of Dell make cpu suitable for honeywell tps3000 with windows 2000 professional OS
3) Alternative solution for 5 slot History module
