do you actually need PAL?
because a lot of people just use a pc monitor and one of these.

Re: Oric-1/Atmos ROM Switch Information
it would be better to use a single 27c256 eprom and a pullup resistor (10k)
and a simpler spst switch.

Re: New Oric Phoenix or Pravetz 9D
how about using an emulator on a raspberrypi or beaglebone etc.
start with an oric, then add the extra ram etc using emulation - it's easier to debug.

Re: Oric hardware museum
caffexpress, like shirtinator and a number of others, act as manufacturers/printers & sales agents for others. in this case, it looks like they are contracted by "old-computers.com" and here it is - looks like they'v been busy!!!! http://www.old-computers.com/store/goodies/default.asp ...

Re: Simplest MMC Interface hardware
just thought i'd give an update, i'm generating the mcu-side schematic. just working out the best way to link 5v & 3.3v stuff at the moment. that, and trying not to design it with anything that will be hard to source. it may be a problem using fram, i think ramtron may be discontinuing 5v parts!...

Re: Simplest MMC Interface hardware
32k of ram - you mean as 2 banks for o.s.? i keep getting confused about why anybody wants a ram chip. and the mcu cant write an o.s. image without sitting on the whole address & data busses - that's gonna eat up all my i/o i'd rather have the expansion rom just written from the oric side. the s...

Re: Simplest MMC Interface hardware
well i'm not so sure, anyway - address decoding can be done later. on the mcu stuff, i looked into some detail. we can/will have ethernet, SD-card(micro-sd) and ps2-mouse. probably joystick - but not sure how. i may need to add a multiplexer because i/o is getting tight. any rom will be seperate fro...

Re: Simplest MMC Interface hardware
consecutive bytes. probably no more than 2 or 4. i want zero page because if you load a file, your gonna run a loop reading from the buffer byte and writing to consecutive destination bytes. just like loading from tape. and obviously reading from page zero uses less cycles so runs faster. also, i wa...

Re: Simplest MMC Interface hardware
o.k. well asuming using hardware address-decoding and an atmel AVR, the sd-card is there, if the atmel has a hardware spi port not used then ethernet is pretty much a given - just add software. if it has a hardware serial port then maybe rs232 or ps/2 serial mouse - again by adding software later. u...

Re: Simplest MMC Interface hardware
that's doable, but if you can show me the software for the ethernet-stack, the usb driver and so on, that still leaves room for an aplication program i'd be pretty surprised. the usb already exists on a number of atmel's, the ethernet is done via a serial port on the same mcu. see this for an exampl...
