C & Assembler conundrum
Here's a straightforward bit of programming for you! Consider the following C code: char *p; for ( p=Fileend; p>Curschar; p-- ) { *p = *(p-1); } What it does is move a block of memory from Curschar to Fileend one byte up (to open a place in a buffer for a character that's about to be inserted). I re...

Re: CP/M Boot Menu?
You could get the menu program to inject the launch command direct into the CCP's command buffer then jump to the routine that interprets it.. Now that would be cool, but you would need to work out where everything is by disassembling the CCP and comparing with a copy of the source (such as the one ...

Re: Amazing homebrew ZX Spectrum & Amstrad CPC
That's true Mark and as I recall no one was worried about waiting for orders to come in - it was the lack of communication after handing over your cash that worried people. If Zaxon's improved in this respect that can only be for the good.

Re: Amazing homebrew ZX Spectrum & Amstrad CPC
Zaxon had an... errm... allegedly mixed reputation on the Atari forums with UltraSatan units. Just saying... Assuming it's the same guy.

Re: CP/M filesystem
CP/M 2.2 doesn't do them, no. CP/M Plus (3) does, I believe. You also get 16 user areas (0-15) which are sort of like directories. Sort of :) Anyway, thanks for confirming that. I am about to see if I can transfer my CP/M setup from the TRS-80 Model 4 to the Memotech. 512 files sounds limiting in th...

CP/M filesystem
Hi all
Quick question for you. What is the capability of the CP/M filesystem on REMemorizer? How many files, directories, users can it hold, and what's the macimum SD card size?
I know I shoukd know all this but I'm hoping someone can save me a trawl through the docs.
Cheers
JonB

Re: Suggestions
We had this discussion about FB when the forum was set up.
I'd personally love to retire the FB group as, like Dave here, I think it's BAD (Facebook, not the group). Perhaps we should move it to another less privacy-invading social network.

Re: Another one lost...
Wasn't that one "I'm selling for a friend hence untested" or some such? In other words, may or may not work properly?
Of course Mark, you'd would have no trouble fixing it. Maybe the buyer wants to build a Kelly generator?
