Not many bits of a 7502 system were suitable for re-use in hobbies mode, which was a shame as keyboards were extremely expensive back in the 1980s. The 7561/1 VDU was a straightforward monitor, quite at home with composite video input. The improved 7561/2 had an interlaced scan and was quite useless. The early model of VDU can always be recognised by its tacky, aluminium brightness control.
