ASSUMED UPGRADES DURING CLAS OPERATION:
======================================

1. TDC Discriminators for old 1920 channels, or keep CAMAC:
      subtract from 5: discriminators (1920 x $75 = $144,000)
      subtract from 8: VME crates for discriminators (7 x $6,500 = $45,500)

2. HV system for existing EC(1296ch), SC(684ch) (3.0mA) and existing 240ch of 0.5mA:
      subtract from 7: A1535(24ch 3.0mA) (1980 x $252 = $498,960)
      subtract from 7: A1932(48ch 0.5mA) (240ch exist x $149 = $35,760)
      subtract from 7: SY1527LC (2 x $7,535 = $15,070)
      ---> $549,790

FADC SAVING:
============

If we can found 40 FASTBUS 1881M ADCs, we can avoid buying FADCs
and save ($1,232k+$144k=$1,376k), but we'll need delay cables
for 2188 new channels (must be included into detectors budget)
and pretrigger electronics; it will effect entire trigger system
design as well but probably make it not very smart and expencive
