Sinclair Research reports that production and distribution of both Interfaces 1 and 2 for the Spectrum are running smoothly.

According to a Sinclair spokesman there are absolutely no problems in supplying the Interface 2 which provides a games cartridge port and joystick facilities for the Spectrum. The product has already gone into retail outlets afte the usual Sinclair mail-order introduction. The more sophisticated Interface 1, however, is still a mail-order only product.

The good news is the production rate is now up to 10,000 interfaces a month. The accompanying Microdrive unit is produced at an equivalent rate - Sinclair is still specifying one Microdrive per interface.

The bad news is that nevertheless demand still outstrips supply.

The Interface 1 and Microdrive are still alotted according to the date of their Spectrum mail-order purchase. So far, Sinclair has worked through the customer list to about the middle of 1982.
