3 <br />compatible as we thought from our look at the proposal in <br />1989. The M9255's operating system is "REALITY ", a combined <br />Pick based operating /data base system, while the P4055's <br />operating system is "PRIMOS ", with "PRIME INFO" running.under <br />that for the data base management system. The electronic <br />mail software, "CONNECTION ", was just not workable with our <br />PC based word - processing solution already in place. All <br />three.of these Prime products are proprietary - they only run <br />on Prime platforms. We have used the Prime platform for the <br />development of our new 1993 Tax Revaluation software and we <br />have moved several other applications, including Elections, <br />to this platform. We have also successfully interfaced the <br />GIS workstations with both platforms. <br />2. Current Equipment <br />The following list recaps our current mainframe capabilities: <br />M9255 <br />176 Open Ports <br />7 MB Memory <br />1 GB Disk <br />2 1/2 " Tape <br />Reality (Pic <br />P4055 <br />(All in -use) 48 Open Ports (20 in -use) <br />16 MB Memory <br />.5 GB Disk (All in -use) <br />Drives 1 1/2 Tape Drive <br />k OS) Prime Info (Pick OS) <br />Prime Connection (E -Mail) <br />98 Adds CRTs <br />17 Prism CRTs (MDCSC) <br />37 Printers (Mainframe) <br />115 PCs (35 emulate terminals - dual PC /CRT function) <br />The M9255 current user capacity is full with all 176 ports in <br />use. The last users added to this platform were put on a <br />switch so three users could share one port. I have requests <br />for three more users to have access to this platform. The <br />P4055 current disk capacity is full with the Revaluation <br />files and the Board of Elections files loaded. <br />Our first option for dealing with capacity problems is to <br />upgrade both platforms. We can add 32 ports to the M9255, to <br />increase capacity to 208, which is the maximum physical <br />limitation of the platform. We can add 1.5 GB of disk to the <br />P4055, increasing it to its maximum capacity of 2 GB. The <br />MDCSC platform would require additional memory along with the <br />new ports as it is approaching unacceptable response times <br />with the 176 active ports. To add thirty two new user ports <br />and an additional 2 MB of memory to the M9255 and an <br />
