=== 64K RAM Limit ===
1. Some Spanish companies may have lobbyed lobbied for a tariff on imported computers, calculators and other electronic machines during the first half of the eighties (*). As a result, the Spanish Government passed an Act (Real Decreto 1215/1985, dated on 17th of July, 1985) that established a tariff on headings 84.52 (calculator and accounting machines, cash registers, etc.) and 84.53 ("automatic machines for data processing", including computers) imported from foreing countries.
2. Foreing Foreign computer manufacturers lobbyed lobbied themselves as a response, and forced the Government to move to an equidistant position: the tariff would be charged only on "micro-computers", that is, "automatic machines for data processing with less than 64 KB of memory". The lobbying movement was so effective that the Spanish Ministro de Economía (equivalent to the head of the British Departments of Commerce and Treasury), Carlos Solchaga, gave up his summer vacation and travelled to Mallorca, were the king was having his holidays, to have the new law signed (Real Decreto 1558/1985, dated on 28th of August, 1985). The urgency of the trip gives an idea of how powerful were foreign computer manufacturers at that time.
3. The tariff charged on imported computers lasted one month only, from the 25th of July to the 3rd of September, 1985. The amount of the tariff per unit ranged from 15,000 to 300,000 pesetas (90 to 1,800 euro at current prices), depending on the type and the value of each particular model. From the 3rd of September, 1985, only computers with less than 64 KB of RAM were charged with the 15,000ptas./90€ tariff, leaving tax-exempt the rest.
4. Amstrad España ([[Indescomp]]) wasn't fully satisfied by the tariff discount, and started selling their allegedly 72 KB model (Amstrad CPC 472) on September 1985 to avoid the tariff. My guess is that Amstrad UK was aware of this movement (maybe not his engineers, but at least the sales department), since the computers should arrive at Spain with the legend "72 KB RAM computer" labelled labeled anyplace.
5. Spain joined the EEC on 1st of January, 1986. The Government had to align his tariffs policy with that of the EEC, and as a result it has to remove the charges on the heading 84.53 (EEC Comission Commission Decision 1985/80908, dated on 15th of November, 1985). There was no point in marketing the CPC 472 model from then on.
* (*) One of them may have been Eurohard, the Spanish company that bought the rights on the Dragon range of computers to Dragon Data at the end of 1984. Eurohard was manufacturing and selling 32 KB and 64 KB computers at that time -the Dragon 32, Dragon 64 & Dragon 200 models-, and developing a MSX-1 compatible computer with no more than 64 KB of RAM.
