P112 Photos
This is a photo of the prototype GIDE adapter installed in the case. The P112 CPU board is under the GIDE adapter:

This is the P112 with a 1MB RAM module, replacing the two 512K RAMs on the P112. It has two 512K RAMs in the SOP surface-mount package style (second RAM is underneath.) You can see the 3-pin header in place of the battery holder used for an external battery:
This is the production GIDE Printed Circuit Board:
The final 'Top Mount' assembly with P112 on the bottom, and two GIDE adapters stacked above it. Note that the P112 battery holder has been removed and replaced with a three-pin right angle header for an external battery. The external battery wire can be seen on the left side of the top photo. The primary GIDE adapter (middle PCB) handles two CF-IDE adapters with 128MB CF modules; the secondary GIDE (top PCB) handles a Seagate 850MB IDE drive and a 32x CDROM drive. Supplied software allows you to read/copy files from a CD. A backup program is being written that will copy the entire contents of both primary GIDE drives (Master and Slave) to the Master IDE drive on the secondary GIDE adapter.
The P112 (semi-hidden), GIDE, external battery, and a dual Compact Flash IDE Drive setup, all on the ATX Mount Plate, in a standard, mid-tower PC case. Also installed are two 3.5" Floppy drives, a CDROM drive, and an 850MB hard drive.
The GIDE mounted UNDER the P112. This is Ken Harty's P112 & prototype GIDE, showing a method of mounting that does not require removal of the too-tall battery holder. Barely visible on the left, the P112's 3x16 expansion connector is mounted to the underside of the P112 PCB. This appears to provide a neater installation with easier access to the various P112 header connectors, but must be provided for during the initial build of the P112, since the 3x16 expansion connector would have to go on the bottom of the P112 PCB instead of the normal location on the top. The GIDE-supplied headers and mounting standoffs for this type installation will work without trouble.
