Appendix C: MP1000 Memory Board

This memory board provides optional, add-on buffer expansion for the Caretaker Plus. Installing this board expands the Caretaker Plus buffer from the standard 64K to 256K, 512K, or 1 MB. "Stacking" two boards allows the buffer to be increased to 2 MB. This card requires the use of 256K x 4 DRAM chips (standard 20-pin DIP type; the speed doesn't matter).

About the Board

This unit consists of a socketed printed circuit board, with spaces for eight DRAM chips. Two 20-pin extensions on the unit's bottom plug directly into the Caretaker Plus motherboard (where the two DRAM chips for the basic 64K buffer go) or may be plugged into another board for expansion. Two threaded metal spacers are included to secure the board to the motherboard, or to another expansion board.

CAUTION! This board is sensitive to static electricity. Handle it only by the edges, and only if using a grounding strap or other commercial grounding device. The expansion pins on the underside of the board are delicate. Be careful not to bend or break them during installation.

Installation

Opening the Caretaker Plus

Unplug the Caretaker Plus power cord. Remove the two screws from either side of the unit, and remove the top cover.

Removing the Standard DRAMs

Remove the two socketed 64K DRAM chips from the Caretaker's motherboard. (They are numbered U13 and U14 on the board, and are positioned vertically near LEDs 7 and 8). These will not be reused.

Setting the Jumper Black

For each board you're using, position the jumper block's small wire jumper. If using only one board, it should be in Position 1 (far left). For two boards, the second (top) board's jumper should be at Position 2 (second from left).

Installing Jack Screws on the Motherboard

If your Caretaker Plus does not have threaded spacers (jack screws) on the motherboard. you will have to install them. Rose Electronics can supply you with the appropriate jack screws. Begin by removing the three screws from the lower rear of the Caretaker Plus. Remove any screws from the bottom of the cabinet, noting where they came from. The motherboard and back panel will now separate from the front/bottom cabinet. You may now install the jack screws onto the motherboard, using the memory board as a guide as to which holes to use. Be careful not to use metallic washers of a size such that they short together circuits on the motherboard. Reassemble the mother-board/back panel by reversing the steps taken to remove it.
