I made a 9pin serial link for my 86 and it works fine with cal in dos except when try to make a memory backup, it always ends saying 'Header too large'. Also, it doesn't work at all under windows. A friend of mine said that I should use a parallel link, but I'd rather use this, since I have an available serial port, but not a free parallel port... Markus Räty (markus.raty@usa.net)
