Quoting (more or less) from a recent catalog: Processor 68000 Clock speed 8MHz (10 or 12.5 optional) DRAM 512 or 1024k (no wait states) SRAM 4k (optional battery backup) EPROM 32, 64, or 128k ROM monitor HUMBUG (tm) included Serial ports 4 (using two MC68681 DUARTs) Parallel ports 2 (using MC68230), usable for printer Floppy int'f on motherboard # of drives 1 to 4 tracks 35 to 80 sides/density single or double disk capacity to 720k per drive clock/calendar on board (with battery) Interrupt timer 2 (I'm not sure what they mean by this) Expansion 6 PC/XT compatible IO connectors "The unique feature of the PT68K-2 is that is it designed to be physically and electrically compatible with an 'XT-style' motherboard..." "Complete systems mount in an XT-sized 'baby-AT' sytle cabinet with a 150-watt switching power supply..." "The system is operated from an external full-sized keyboard and video display. You may use an RS-232C terminal... Alternatively, you may use an IBM XT/AT- compatible keyboard and either a monochrome or CGA video display board and compatible monitor (plugged into the expansion connectors on the system board)." "A floppy interface is mounted on the system board, or an inexpensive external hard disk controller may be used. The PT68K-2 supports the PC/XT-compatible Western Digital MFM controller card such as the WD1002-WX2 or WD1002-GEN, which will plug into one of the IBM-compatible io slots. Any ST506- or ST412 compatible hard drive up to 64 megabytes can be used;..."
