Everybody know the M4 wifi board by Duke for our Amstrad CPC. The M7-Galaxy board is an extended version of the M4 but intented for the Amstrad GX4000 as the board will interface inside the Z80 socket while le processor is on the board. It features :
disk drive emulation, it emulates the DFC765 chip so all read/write accesses are redirected to a .DSK image like a Gotek or HxC without the need of a FDC chip
RAM expansion, probably 320 Kb + the original 64 Kb
The Zen80 board is similar to the galaxy board, but is used as the M4 board : externally and not internally. It will feature 8MB SDRAM (and MCU with more GPIO's), which would be hard to fit in the internal version without going BGA.
The boards will have an approximative price of 60 euros, there is no preorder at the moment.
Kimo-Hachi, a hand-made MSX, anyone done the same with an Amstrad CPC ?
An interesting information, a japanese engineer built a hand-made MSX computer, not with FPGA but with hard wired general chips, with several main board each one having the role of a fonctionnality of the MSX (one mainboard for video for example).
Doragasu started a project in January 2017 about a ROM board interface with DMA transfert. The project is now a reality :
it can play digital audio with approximately 0% CPU overhead. The limits are the bits per sample ( 8 ) and the maximum sample length (64 KiB). Sampling rate can be configured on the fly, and ranges from 3906 Hz to 50 kHz (and beyond)
it can can transfer data from external ROM to internal CPC RAM at 1 byte per microsecond. While doing DMA the Z80 is stopped, but this is much faster than doing the copy using software routines
Amstrad CPC mini incoming, but it's a bad news finally
April Fool ALERT, April Fool ALERT
I have received the same email than Markus Hohmann as he announced it on Facebook.
So Alan Michael Sugar is asking to remove all ROMs of the Amstrad CPC firmware for a copyright reason as an Amstrad CPC mini will see the light later this year.
I was waiting for such a beast, but I didnt think about possible consequences. Though I will respect what he is asking as I have never wanted to put illegal programs on this web site.
New version 130318b of YANCC by SOS for the XMASS extension card
A new version of YANCC (Yet Another Norton Command Clone) is available (130318b). It's a text interface to manage your files on the X-Mass and the AcmeDOS ROM with an interface which looks like norton commander or midnight commander).
Fixed Unwanted starts of YANCC during Warm-Reset (e. g. Monty on the Run)
In rare circumstances, some files are copied empty.
In rare circumstances, the ROM-Init of YANCC makes nonsense... (e.g. in "12 Lost Souls")
It's this new version which is needed if you want to use the new ROM CubeIOS which replaces ACMEDOS.
CubeIOS, a FAT16,32 IDE-OS ROM for the Amstrad CPC's with XMASS
The XMASS mass storage extension card can now be used with another ROM, that is CubeIOS :
Detect (nearly) all Fat16+Fat32-Partitions on your CF-Card, DOM, etc. (1st Partition please). Prefered is Fat32 (should be faster with Save-Commands). You can format the media with e.g. Windows and fill it with data.
the usual RSX like |MD, |RD, |REN,....
|DIR + |CD accepts wildcards
Compatibility should be high (i hope so ;) ) - but i'm playing around with a lower-rom-patch to increase compatibility.
The ROM must be placed below AMSDOS and (if used) M4DOS, PARADOS. It's not compatible with ACMEDOS at the same time. YANCC-User should be update to the latest version.
