Cst Thor

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The CST Thor series of personal computers were Sinclair QL-compatible systems designed and produced by Cambridge Systems Technology during the late 1980s.The original Thor PC (also called Thor 1, sometimes also retrospectively referred to as the Thor 8), was launched in 1986, as a logical progression of CST's QL peripheral business after production of the QL was halted. The remaining stock of QL parts were purchased from Sinclair, and the standard QL motherboard (including a 7.5 MHz Motorola 68008 CPU and 128 KiB of RAM) was augmented with a CST-designed expansion board providing 512 KiB of additional RAM, extra ROMs, a non-volatile real-time clock, floppy disk, SCSI, Centronics parallel, IBM PC/AT-style keyboard and mouse interfaces enclosed in a low-profile metal desktop case with a built-in power supply. Mass storage options consisted of one (Thor 1F) or two (Thor 2F) 3.5-inch floppy drives or one floppy drive and one 20 MB Rodime RO652 SCSI hard disk (Thor 2WF).
