However, it does sound as though there is something special about your banked ram, or something. Do you unzip things off the ram drive (I would do this anyway because it is faster -- I only discovered the problem when I had a small ram drive (one bank, instead of the usual two))? This has no problems. It is only off the floppy disks, and it needs to be a pretty big file (in another post I mentioned it happening in 15 128-byte blocks out of about 2000 in a file) for the "random" chance to happen. > May I hazard a guess that you're running ZCPR or similar, or > something else non-standard? I am running CP/M+, as supplied, with a serial interface (no special patch), and a ram disk (and the patch for it). The ram disk consists of both banks of ram, although I have had the same problem with just one bank plugged in. I think I may even have had problems without any ram plugged in, but the patch installed. The serial interface is a possibility, I guess -- who else of those with problems has a serial interface attached to their system? This does make me think of the ram patch as being the problem, so I have started to disassemble it again. If anyone is interested in helping work on this, you will need a copy of PATCHER.COM (out of the ram disk rom), and a copy of DazzleStar. I will send a copy of the DazzleStar temporary file, which defines the symbols, etc. Anyway, it is amazing how many Amstrad users there are out there. Three of us have had problems, and one hasn't. There seems to be little difference between the setups. We have, however, learnt that there is no problem with using the ram drive, but there appears to be with using the floppy drives. On a random basis. Does anyone know different? -- Ewen McNeill. Email: ewen@actrix.gen.nz
