Hi everyone,
Not sure if anyone has seen this yet, but it's a real (new) Z80 microprocessor retro computer which also utilises the Esp32 as a coprocessor. It also runs BBC BASIC. Oh, and in benchmarks it's much faster than the very much anticipated Spectrum NEXT!
It's available for €50 and £58 from the links at the bottom of this message.
From the OLIMEX website:
OLIMEX Argon Light V2

hi, my unit it's a shugart 8" with a 50 to 34 pin converter and a jumper to set Ready signal.
It's a Single Side / Simple density unit and only test format in data / system 178-169 kb's....
To connect power supply it's another war: 110v, +5 -5 +24 and -24v
Nothing special, but format 8" floppy disc with an amstrad cpc it's magic

OK, this seriously has to happen.
ICs are getting easier and cheaper to find again now, so mark me down for one.
You're the only man that can do it, Duke!

So... Looking forward to this arriving!
C'mon Mr Postman, hurry up!
Quick question.
Near the beginning of this thread, someone found an enclosure (box/case) on eBay that was nearly perfect for the M4. Unfortunately that listing was a while ago now and the it's gone.
Does anyone know which case it was - the manufacturer and ideally the case number?
I'm not too keen on printed cases as they always look rough with a bad finish - certainly not worthy of putting an M4 in! 😂
Many thanks.
Steve

Last post by CPC 72 - Yesterday at 20:05Thanks for the good advice On the cpc 664, the disc drive is located above the power switch. It may be some work to remove it first and I will not risk ruining anything either. I rather wait until the problem gets a litte worse than it is right now

I'd just do:
LD HL,0
LD DE,0
LD BC,#4000
LDIR
At the start of the startup ROM. At which point it won't matter if it gets paged out, since ROM and RAM from #0000 to #3fff will contain the same data anyway.

I guess a concern doing this is that you can't do this running code from the mapped low rom as it'll disappear once you remap it... So the bootstrap sequence will be
- Enable Plus features
- Copy bootstrap to ram (at &4000 seems convenient)
- Jump to bootstrap
Bootstrap:
- Map X low-rom bank at &8000
- Copy &8000 to &8000
- Unmap bank
- Jump to &8000
- Enable Plus features
- Copy bootstrap to ram (at &4000 seems convenient)
- Jump to bootstrap
Bootstrap:
- Map X low-rom bank at &8000
- Copy &8000 to &8000
- Unmap bank
- Jump to &8000

Quote from: Bryce on Yesterday at 17:12If the cassettes aren't welded closed then just loosening the cassette screws can help.No screws.... I'm just now "twisting" the tapes and rewind+FF in another cassete deck... Gonna try again in a few minutes in the CPC
