I've just been given an Epson HX20 laptop - it was not working when I got it, but it didn't take long to kludge over the damaged conductor in the keyboard flexiprint cable... Anyway, it came with some rather nice bits : The microcassette drive and 8 tapes A TF20 floppy drive unit and cable A pile of manuals - user manuals for the HX20 and TF20, BASIC reference manual, and _Technical_ manaul for the HX20. The latter is quite a find, and includes schematics of the machine, the tape unit and the ROM cartridge. I am lacking the systems disk for the TF20 - does anyone have one that they could make a copy of. I can supply a blank disk and pay postage, of course. I suspect that as I have the machine, I am entitled to have such a disk. I assume schematics for the TF20 don't exist anywhere... The TF20 contains a pair of 1/3 height voice-coil drives (like those in the QX10), and a controller board. The latter contains a Z80, 2K EPROM, 64K DRAM, the 765 disk controller chip, and TTL glue. There's a daughterboard with the serial chip on it to communicate with the HX20. This reminds me of another Epson object I have - a BM5 floppy drive. This looks like the TF20 (it's a white box, very deep from front to back, with a vertically mounted drive on the front). However, this drive seems to link to the internal controller using an ST506-like interface (34 pin and 20 pin cables), and the controller chips are hard disk controllers. Somebody told me that it stored 5 Mbytes/disk Does anyone know anything about this object? -tony
