The new Superfo cloneHi In the spanish forum speccy.org some guys and me have optimized the superfo clon to have less ICs. The actual design has 39 ICs versus the 45 ICs…
You can use the ROM B of a +2A to boot in 48K mode, then load a tape with a program that writes into the EEPROM, and finally swap the ROM B with the AM29010. The 27c256 must fit between pins 3 to 30 of the socket, and you must supply VCC to the pin 30. -

No, sorry, it doesn't. That's a 16K?8 EEPROM and A13 [I]is[/I] wired up appropriately to allow selecting between two banks of 8K. -

Now I am working in a project that aims to use Multiface 1 for EEPROM programming. In my first attempt I have just succeeded in writing a 28C64 EEPROM.
I shall submit the software to WOS when it is finished. -

If the ROM(s) in your Speecy are in sockets (bases), it is also possible to program a EPROM or a EEPROM chip with the RAM test software. Then remove the Speccy ROM(s) and plug in the test EPROM / EEPROM chip.
