13. FLASH DISK PROGRAMMER BOARD
The Flash Disk Programmer Board accessory model no. ACC-IDEEXT may be used for several
purposes. Its primary purpose is to enable the simultaneous connection of both a flashdisk
module and a standard IDE hard drive or CD-ROM drive to allow file transfers to/from the
flashdisk. This operation is normally done at system setup. The board can also be used to enable
the simultaneous connection of two drives to the CPU.
J1 connects to the IDE connector on Prometheus-LC with a 44-pin ribbon cable (Diamond
Systems’ part no. 698004). Both 40-pin .1” spacing (J4) and 44-pin 2mm spacing (J3) headers
are provided for the external hard drive or CD-ROM drive. A dedicated connector (J2) is provided
for the flashdisk module. Any two devices may be connected simultaneously using this board with
proper master / slave jumper configurations on the devices.
The Flash Disk Programmer Board comes with a 44-wire cable no. (DSC no. 698004) and a 40-
wire cable no. (DSC no. C-40-18) for connection to external drives. The flashdisk module is sold
separately.
The 44-pin connector (J1, J2, and J3) and mating cable carry power, but the 40-pin connector
(J4) and mating cable do not. J5 and J6 on the accessory board may be used to provide power to
a 44-pin device attached to the board when the board is attached to a PC via a 40-pin cable.
These headers are compatible with the floppy drive power connector on a standard PC internal
power cable.
