compatible drives the TEAC drives were rather noisy in operation, compared with the other 96 TPI drives. They are even noisier when used with either of Gemini’s FDCs. [Ed – this is probably so with the early Gemini CMB09 FDC board, but with the GHa29 and GM849 boards the drives may be stepped at their mazimim rate (3mS) (With the VFC and GM809 only Gu 1 possible, which resulta fnithe nolse.)

‘CONCLUSIONS

As far as most software is concerned, the use of the VEC poses no problems In

Y view, the VEC represents » good, reasonably Low-cost attempt to bring the -nloubted advantages of disk operation to Nascom 2 owners; for someone starting Gp with CP/M, the purchase of s Gemini CMO13 or MAP CPU card and the VFC Fepresents « considerable cost saving on the minimum ‘all Gemini” system where 3 Boards are required Some useful features available with Gemini‘s current video and floppy disk controllers are not found on the VFC but both che extent of One’s purse and the type of application may well be the deciding factors,

The ceady-bullt full version costs £214 + VAT: other versions are about half thie price In kit form, the full vereion is £175 + VAT and would take a couple of evenings to build; the video-only and floppy-only versions cost £99 + VAT. Mar 60 Systems are now in Egham (0780 37674),
