Call for final Elf99 design input

< Options under consideration: < < o Sockets for two 1822/2101 256x4 SRAMs, the same style used by < the original Elf. < one 2116 outweighs that. <o A 1851 programmable input/output port -or- a pair of 4508 latches Use the one that is available. < wired as one input and one output port (as in the COSMAC VIP) Handy and useful, do the ports. < o A 1854 UART Desirable. < o A protoyping area of .1" spaced plated-through holes, nominally < a few inches long by one or two inches wide. < < o Either a dual 4042 address latch or a single 4508 latch. One or < the other is needed to implement more than 256 bytes of memory. < This would be optional in a machine built with dual-256x4 SRAMs. Consider 74hct373. < o A pre-programmed 27256 with a "library" of simple programs < (Accessible by enabling the ROM switch, setting the program < number in the switch register, then setting the control switches < to "run"). Good idea! I have sources for minimonitor and UT4(RCA) plus a buch of others in hex from articles. < Did I miss anything? Any other suggestions? I will not be including sp < for an 1861 because I have been entirely unable to locate a source. Long gone. < Do we still have any interested parties? I have saved the addresses of < all who have initially expressed interest, so I only really need to know < these features are attracting people or putting them off. Yes! Allison
