I am trying to find out if anybody is interested in any of the
Micro/Elf expansion boards to see if it is economically feasable to do
a production run of them. The following expansions currently exist
for the Micro/Elf:
1. Expansion board, provides a 32k (.6") socket jumper selectable for
eprom, eeprom, sram, or nvram, decoded for addresses >= 8000h. There
is also an IDE/CF interface and a Q/EF? serial port. Note: this board
can also be used with other Elf systems to obtain the additonal
ram/rom socket and the ide/cf interface. the board uses processor
signals (D, A, N, TPA, TPB, SC0, SC1, Q, EF, MRD, MWR) as its interface.
2. Hexkeypad. This expansion provides a hexkeypad that can be plugged
into the 74ls244 socket on the Micro/Elf.
3. PS2 keyboard/1861 video board. This board provides an interface
for using ps2 style keyboards on the Micro/Elf as well as providing
1861 Pixie graphics.
If you are interested in any of these boards, please let me know.
If there is enough interest i will have the boards manufactured. If
there is not enough interest, the board design files exist on my
website and you are free to use the design files to have your own
