95A Compatible Complexes
  Sorry, folks, but personal experience (supported with that of others, BTW) proves that running any other complex but a Type 4 (N, P, Q, or Y) WILL result in a 172 error code. And that's all you will get. The planar is fine. It just won't work. Replace the complex with a Type 4 and it will come up fine... 

JMP 6 Remote Maintenence Processor
   If you do NOT have a ServerGuard adapter installed, this header MUST have a jumper on the two pins on the right. Otherwise your system will NOT power up. Also look at JMP6. and also the power stuff. 

Hacking an 8595 Case
   Yes, you CAN put a 95A planar into a 95 case. Basically, you have to extend the port opening downward until it's 9 1/16" long. The metal frame port opening must be extended downward so it's 9 1/16" long. 
   First, pull the complex, adapters, power supply, drives, and planar. Then remove the rear bezel by removing the 5 hex head screws. The rear bezel will pivot upwards like the front bezel. Now you can hacksaw the frame opening downwards. I used a coping saw to cut across the bottom of the opening. 
   Do the same to the rear bezel. Take a file and smooth up the cut edges (or you WILL pay for it later!). The metal frame has a very thin web left next to the opening for the power supply. It bent on me when I tried to bend up a lip for the longer EMC spring on the planar. Just say the hell with it and cut both sides of the port opening straight down. 
   The real difficult part is to put the rear bezel back on. It SEEMS easy enough. You start by putting the "hinges" on the top of the pivots at the back of the case. Now try the delicate ballet of exactly lining the rear bezel up with the lips on the metal frame It took me a good 20 minutes. Note the bottom of the expansion slots has a lip that the rear bezel MUST fit onto. 
  I now believe that cutting the frame while the rear bezel is still screwed on will be the easiest way. I would still clean the fresh edges up with a file. Use compressed air to blow any metal fragments out. 
   Put in the new planar. Match up the spring clip with the lip on the frame. Push forward and pivot the planar downward onto the lip. Make sure the screw holes match up- the planar can be too far up or down on the lip. To adjust the height, pull the planar up and to the rear. When it comes loose, move it the correct direction then reseat it. 

Y2K Level 1 Compliant
   After arduous testing in the Fortress of Solitude, I have determined THE requirement for Level 1 compliance, and that is the Dallas DS1585S Serialized RTC. This chip has the required routine to accept the rollover all by itself. Other MBs that use the older Dallas DS1285 are Level 2 compliant. (all 90s, all M class 95s, possibly X class 85s). 

IEEE1284 Parallel Port
   LPT A (bottom parallel port) is IEEE1284 compliant. It is capable of transfer rates up to 2MB/S. It is also called Expressprint. There was a prototype multiplexor for it called the F/MUX. Parallel Port B (top parallel port) is a standard PS/2 bidirectional port. 

Serial Ports
   Both DB9 serial ports are capable of 345K/S. 

Synchrostream Capable
   This planar supports SynchroStream (for whatever good that does). The design lets both the 32 bit data bus and the 32 bit address bus be used for sequential data streaming after the initial data address is sent. Go to Data Transfers for more info. I haven't seen any suggestion that any particular OS fully uses SynchroStream, not even OS/2. 

LogicLock
   This interesting bit of security hardware is a mechanical switch that detects if someone has attempted to open the case without using the key to unlock it. First, you need to set the administrator's password. NOTE: If you forget the administrator's password, you will have a planar that will not work. There has been some attempts to replace the DS1285, but that's not the complete fix. A VPD error keeps occuring. It seems the password is stored in two locations? 
   Next you need to set the unathorized access monitor to "Enabled" under Set Configuration. NOTE: I do not advise you to set the unauthorized access monitor to anything BUT disabled. 
   I'm still trying to understand WHAT the LL will do after someone attempts to pry open your 95A system. It will definately log the attempt. But what does it do after? 

Wake on Ring
   This planar supports Wake-On-Ring, either from an external modem, or internal. The system will power up after detecting a ring on Serial 1 or on a modem. 

Wake On Time
   You can set the time and day you want this machine to power up. See Quick 'n Dirty Setup
