Manufacturer: IBM
Machine Type: PS/2 Server 95
Model Number: 9595-1NT
Serial Number: 23Y5705
Current Status: Excellent. Complete and working
Acquired: Sep 1999
Remarks:
Although this PS/2 model is below the 10 year criteria for classic computers, it is being included in the collection due to its classic MCA bus. This Model 95 has all the easy to use features and advances of the PS/2 family and also includes a tamperproof cover, 300 watt power supply, security features, LED information panel, and selectable start options. Model 95s use a processor complex of which there are 486 50, 66 and pentium 60 and 66 Mhz speeds. Current configuration of the machine follows:
Type 4 486DX2/66 processor complex
64meg ECC memory
3 SCSI hard drives for a total of 4G total hard drive space
Toshiba (IBM badged) caddy-type CDROM
IBM 4/10G 4mm tape backup
IBM Lanstreamer NIC
Cabletron E31 Ethernet NIC
XGA-2 video
PCMCIA adaptor /A
This 95 has OS/2 Warp Connect installed and still sees active duty as a backup server for a small peer to peer network and also performs net access. All partitions are formatted HPFS except for one partition that remains FAT. The original SVGA video card was replaced with an XGA-2 video card which allows 1024x768x256 colours and improved video performance. The last addition was a M-ACPA /A which is a sound card. Once the .adf file was read in and sound support files were installed in OS/2, the sound card worked with no further changes after a reboot. The PS/2 has no problems attaching to Win9x computers when OS/2 Peer was installed. When setting up OS/2, the domain should match the windows' computer workgroup name and drives/directories should be shared out. Also, the machine should be given a name so that it may be located on the network.
This computer made the Y2K transition with no problems whatsoever. OS/2 only shows two digits for the year, so the date now reads as mm-dd-yy.
Effective 20sep00, this computer now runs Warp Server and uses TCP/IP to connect to Win9x machines.
Some time ago, the machine was put away and then brought back to life but strangely enough, it would hard lock. Diagnostice were run, but as soon as the WPS loaded, it would stop right there. After several reloads and swapping parts, it was determined the NIC was bad! Replacing it with an identical component fixed the problem. It's rare the Microchannel parts fail though.
