Description
ZX Spectrum expansion unit that shares some elements with the SAM Coupé and SamBus.
From Your Spectrum magazine, May 1985
The GORDON MICROFRAME plugs directly into the back of any Spectrum, allowing the user full control of over 256 I/O channels through its 5 slot motherboard.
It also has a floppy disc controller interface which boots the operating system into 16K of memory which shadows the BASIC ROM. The operating system supports basic commands
such as LOAD, SAVE, MERGE, ERASE, CAT, OPEN and CLOSE.
