[Aluminium coated paper printers] How did the original TRS-80 screen printer work -- the one that plugged into the expanison bus and read out video RAM? The 'Quick Print II' (or some very similar name) was a Radio Shack aluminium-paper printer certainly. IIRC it could be linked to an RS232 interface, Centronics interface or the M1 expanson bus where it responded to the same addresses as the normal Centronics port in the Expansion Interface. The thermal printers, like the ones in HP calculators from the HP9810 onwards become unreadable from age (fades out), heat (obviously darkens the paper, and it doesn't take much to do it, a soldering iron an inch or so away has a noticeable effect), propan-2-ol (causes a chemical reaction that darkens the paper, don't ask how I found that out), etc. If you want to preserve the output, scan or photocopy it -- any other process has a longer life!. Worryingly I had to tell this to a member of staff at the British Library who was archiving HP calculator printouts... Certainly not an aluminium-coated paper. -tony
