    You should have about 63K IFF you have no RAM disk (ie you have an external RAM disk unit present), and you have no user bios space set in the configuration. If you changed the settings then after a...

    Run a comparison tool on them first if you are paranoid. It will at least guarantee that they are the same bits. chkdsk doesn't really help. It tells you the new drive is logically consistent, not...

    The Tandy MC10 is 6801/3 so that is one place and group to look for 6801 information. The 6801 is actually way better than the 6800 because it fixed a whole bunch of 'doh should have had an...

    CP/M was on the downslope but it was cheap. Epson had a good deal of success with the PX-4 and friends which ran CP/M, had a 40x8 screen and were launched 1985 onwards.

    The Amstrad PCW series were...

    I've found it varies a lot by machine. BBC micros the power supply caps explode and you also have to reseat all the ICs every few years. I've bought a number of "dead" BBC micros I fixed with nothing...

    It wouldn't be very hard to port some of the modern runtimes for Scott Adams to LSDOS. The C one I wrote fits in well under 32K including game file and the 6803 asm one I wrote to run them on the...

    LBX died in part because low bandwidth rapidly didn't become the problem - high latency did. There were other schemes that cached stuff better - like NX.

    Your scheme sounds rather close to VNC....

    If it's the same as the one shipped with Z80Pack then the cpmm2.2 disk for the 16FC is an utterly generic 128 bytes/sector 26 sectors/track 8" disk single sided single density disk.

    Are you trying to find an existing bootable CP/M or build and boot your own ?

    The 16FDC at least simply loads 128 bytes of memory at 0x0080 from the FDC and jumps to it. The rest is up to you. The...

    There were a tiny number of ISA to USB (and thus PCMCIA to USB) chipsets. The cards are rare as hens teeth and you'll need the right drivers and only get limited device support.

    CF adapters will...

    It would probably be far more productive to port EmuTOS to the retro style systems and get at least a large chunk of the Atari ST command line stuff running on it (as well as a FAT fs). GEMDOS is...

    Fire it up under Linux. It's not going to magically make it work but you'll get actual meaningful diagnostics and see how far the system got into finding it (if at all). There are so many reasons...

    The libraries build but it broke gcc and gnu binutils too much to proceed further. gcc appears to have been fixed but not yet binutils. In many ways it is not a good fit for the PDP anyway. One of...

    The Scott Adams games are entirely table driven, although apart from a very early adventtureland the interpreter ended up in asm. It still has some basic hangovers though like squashing everything...

    If you could that would be good - I turned on my 8512 to make the disk image for him and I've got no 12v line and 2.6v on most of the CPU lines on the expansion bus lines ... 8(

    The Memotech MTX CP/M systems do have an API for reconfiguring disks and commands to do it. In the olden days it let you tell the system what sort of disks you had attached after boot and what sized...

    The original ARM even more so. It's a thing of beauty and a tiny number of gates (25000 transistors) yet at the time it could do things like big memory manipulations at twice the speed of a 68000 on...

    The killer for a compiler is the extra registers and the indexing. That turns a pile of code doing lxi h,n dad sp, mov e, m inx h mov d, m into something much cheaper. In fact even more so because...

    Sadly 2019's list now contains 'repair Amstrad PCW8512'. Think the power supply has gone as I have no 12v line and most of the external interface bus lines are sitting at around 2.6v

    Two things to also check

    1. Is there a write protect jumper somewhere on the board that would match up to this ? You may have to trace it as it's quite likely to be one of those 'factory...
