GRiDCASE 1500 Series

OK, now on to my _other_, less successful GRiD find yesterday... I picked up a GRiDCASE "1500 Series" computer. It looks very similar to the Compass that I'm typing on, but with a larger screen, 3.5" floppy drive on the right hand side, standard PC ports, and mushy keyboard. Anyway, when I turn it on, the *fantastically beautiful* 10.5" (diagonal) display reads: Phoenix 80286 ROM BIOS Version 3.06 <blah blah blah copyright> GRiD Systems Corporation 3/17/88 640K Base Memory, 00384K EMS Memory Time-of-day clock stopped - please set current time A green LED comes on, next to the label reading "Lower/External disk in use". It sits there for a while, then beeps with the message: Hard Disk Diagnosic Failure Strike the F1 key to coninue OK, so this looks like a clock battery gone dead, making the machine forget the setup. I tried booting up with a 720K MS-DOS floppy, but that didn't work. There was a slight noise, and the "Upper disk in use" light came on momentarily, but it didn't boot. It went back to the other light and evntually complained about the hard drive again. Unless this thing uses some kind of Stealth Hard Drive, there doesn't seem to be a hard drive in there at all. No HD noises. Also, there is a lift-up trapdoor above the keyboard. Opening it reveals two empty 32-pin sockets. So, how the heck to I crack the case on this thing? The only screws I could find with a cursory inspection were the four screws under the carrying handle. How do I get to the suspected dead battery? -- Doug Spence ds_spenc(a)alcor.concordia.ca http://alcor.concordia.ca/~ds_spenc/
