Bill Wrote: I will have to agree with you here. I find the spring car boot sales here in the UK tend to be very good, and the ones over this holiday weekend to be especially good. My find of the weekend was another Anita calculator that has a nixie tube display. (My dad is getting very good at spotting calculators at the bottom of a box.) It does have a few problems but more on this later. The Anita was among the dozen calculators, two Intellivisions (both with speech modules), various Atari XE & 2600 cartridges, a G7000 + a dozen carts and the first reasonably priced (3 pounds) Spectrum +2. I also picked up a couple of old Speak & Spell and a couple of Little Professors (one LCD & one LED) These last ones are educational things for my new daughter, well that's my excuse anyway. The Anita mostly works. The tubes all work, it is just the number keys produce the wrong numbers. One of the circuit boards looks like it has some water damage, and maybe some rust under the whiteish residue. What is the best way of cleaning this? -- Kevan Old Computer Collector: <URL:http://staff.motiv.co.uk/~kevan/>
