Sharp CE-515P - need more pens! (also: Multitech MPF)

Hi, A few of you might remember my Sharp CE-515P plotter. Well, my pens are almost completely devoid of ink and I need more. I know All Electronics sell a pack of 4x black pens, but I'm after the four coloured ones (blue, green, red and black). I'd really like to keep this thing running, but if I can't get the pens then I'm afraid I'm going to have to relegate it to the cupboard... Alternatively, if someone wants to donate a working flatbed (preferably A3-size) plotter to my collection... BTW, anyone got a Monitor ROM dump, memory map, schematic diagram, etc for the Multitech MPF-IB or MPF-I (the one with the green starburst display)? I'd like to have a go at rebuilding one. Just for the hell of it :-) Later. -- Phil. philpem(a)bigfoot.com http://www.philpem.btinternet.co.uk/
