Thanks, I figured it HAD to be a typo, otherwise it would be rather ironic for it to have more than 5x as much RAM as the standard 100 could support. On Mon, Jan 8, 2024, 12:05 Darren Clark wrote: > I think the 128K or RAM is a typo and should only be 128 bytes. Looking at > page 97 (set the dat

Geez, up-front the manual said 128K of RAM! I was thinking one could reprogram the ROM to make it a ram disk for a sec there, but the parts list only shows 2K of SRAM unless I missed something? Anyway, thanks much for the efforts, all! Great stuff. Tim On Mon, Jan 8, 2024, 10:23 wrote: > Th

Thanks for the Deoxit tip! I have a Casio VL-Tone that has two scratchy sliders but is otherwise pretty perfect for a 43-year-old device, may give that needle bottle a shot. On Fri, Jul 16, 2021, 22:56 Greg Swallow wrote: > Hey Earl, > > Welcome to the list. > > Deoxit on the pot. Amazon has it

Re: [M100] User number in CP/M for M-100?

2020-10-06 Thread Tim Russell
The "user number in prompt" and "execute from user 0" thing are BDOS extensions from a given manufacturer and not part of standard CP/M 2.2, if I recall correctly. It may have become standard in CP/M 3.0, but that's not really germane here. On Tue, Oct 6, 2020, 17:26 Bert Put wrote: > Hello, >

I still have one, and a PX-4 as well. Both can also use a battery-powered serial-connected 3.5 floppy drive, which I also happily still have. On Wed, Mar 11, 2020, 13:51 Tom Wilson wrote: > Also, if you're looking for an 8-bit CP/M laptop, the Epson PX-8 is > exactly that. It runs CP/M from ROM

I have both a PX-8 and a PX-4, and I /believe/ they run straight off power alone but am not positive. If you can't get an answer let me know and I can experiment for you, both are in a box in my room at home easily at hand. They both have ramdisks attached as well. Tim On Fri, May 8, 2015, 12:3
