 Sinclair's persistence with the non-standard Microdrive and uncomfortable keyboard did not endear it to the business market; coupled with the machine's resemblance to a ZX Spectrum+, they led many to perceive the QL as something akin to a toy.Software publishers were also reluctant to support the QL due to the necessity of using Microdrive cartridges as a distribution medium.The QL's CPU, ZX8301 and ZX8302 ASICs and Microdrives formed the basis of International Computers Limited's (ICL's) One Per Desk (OPD) - also marketed by British Telecom as the Merlin Tonto and by Telecom Australia as the Computerphone.
