Title: CP/M plus (cpm 3.1) on a CPC 464 with Ram Expansion
Post by: CraigsBar on 15:11, 26 April 21
Hi all.


I am sure I used to run CPM Plus on my expanded CPC 464. But now no matter which disc image I use I get a message stating that CPM Plus will not run in this environment.


I also vagely remember a "Universal" patched CPM Plus disc that would boot on any CPC with 128k or more memory.


Have I gone insane or am I remembering this correctly and if so where could i get this DSK?


Many thanks


Craig

There are some notes in the DK'Tronics expansion manual on patching CP/M to run on a 464 - see the CPCWiki page (https://www.cpcwiki.eu/index.php/Dk%27tronics_memory_expansion#CPM).


I sometimes run CP/M Plus on my 464 but I haven't patched my copy of CP/M. I have the CPC6128 firmware and BASIC ROMs installed, and then I load the DK'Tronics RSXes (download from the same page linked above) and type |emulate before launching |cpm.

I found it.... when I say I, I actually mean @Shaun M. Neary (https://www.cpcwiki.eu/forum/index.php?action=profile;u=728) found it... It'd on Richard Wilsons WinAPE Download Page, http://www.winape.net/downloads.jsp in the "Other Downloads" section, 4th file down.

I have now patched the patched version with the DKTronics Silicon Disc Installer so that the end result is a CPM Disc that maps all available expansion ram (over 128k) into a Ram disc up to 444kb in size and boots perfectly on any CPC I try it on. Perfect for my external Gotek "utilities" folder that is.
