James B says:
this patch marks the disk – Level 1K – my disk of 631 is Level 1H. Are there patches for levels 1I or 1J or were those levels just skipped (… Hmm is that an I or a one ? )
Matthew Reed (TRS80.org) says:
Level 1H was the final official version of LS-DOS. But there were unofficial patch sets that used 1I and 1J. I thought it was better to jump to 1K to avoid confusion.
Ronald Garbin says:
So far the 2012+ date extension patches work perfectly on our real Model 4ps, and the resulting LS-DOS631k has no trouble supporting a heavily-patched version of the old ProSoft word processor Allwrite. About the (registered) Emulator does occur a question.
To laser print documents with the maximum of formatting space, my patched Allwrite loads into the real 4p’s resident bank(s) character width tables each of only 2 bytes. Those bytes are really pointers to the various fonts' full-sized width tables, 283 of them, in the computer’s bank 3. Might the Emulator on a non-TRS-80 allow something similar?
