     Hi -
     My name is M. David (Dave) Johnson and, like many of you, I just
     rediscovered the CoCo after many years of absence.
     I got my toes wet with the VCC Emulator, and now I've purchased a
     64K CoCo2
     from the colorcomputerstore. I also picked up a floppy controller
     and a 7"
     TFT LCD monitor on ebay, some cables from Cloud9, and a CoCoSDC and
     (on
     order) a CoCoVGA from Zippster.
     When I voided my Warranty and opened the CoCo to verify that the
     MC6847 was
     socketed, I had a stray thought concerning a possibly different
     method of
     emulation.
     So, I also I checked the other IC chips and then went out to the
     internet to
     try to locate DataSheets on them. I was successful with most, but
     some I
     could not find. Would anyone here happen to have (or know where I
     might
     locate) DataSheets for the following:
     U1 - SC77527P 8345 SALT (possibly custom by Tandy),
     U3 - SC77526P 8352 DAC (possibly custom by Tandy),
     U12 - 8040364B 8340 ROM Basic (perhaps vaguely similar to a M2764A
     8K x 8
     EPROM ??),
     U13 - SCM92135P 8042364A 8343 ROM Extended Basic (perhaps vaguely
     similar to
     a M2764A 8K x 8 EPROM ??),
     U14 through U21 - 8040665 PQD8350 64K x 1 DRAM (possibly similar to
     a 4164)?
