[net.micro] simple/cheap Z80 systems

gvw1 (10/20/82)

I would (and will when I have saved up my paso's) go with the
Big Board II by Cal-Tex Computers (780 E. Trimble Rd., San Jose, CA
95131). It has some of the following features:

4 MHz Z80-A and peripheral chips

64K Dynamic RAM + 4K static CRT RAM + 24K E(E)PROM or static RAM

single or double sided, single or double density 5.25 or 8 inch floppy
disk interfaces

80X24 7x9 dot matrix video

STD bus interface

DMA

SASI interface for winchester disks

Runs CP/M (registered trademark of Digital Research)

Advertised prices are 895 assembled, 696 full kit, 245 PC board with
EPROM & PALS

I plan on going with the kit, but I have a computer hardware/software
background. If one didn't have a lot of electronics background, I think the
assembled (& tested) one would be the right one to get.

However, as I said before, I don't have one yet, but it sounds
good to me because I am also looking for inexpensive but powerful micro-
computer.

There's a relatively new magazine called Micro Cornucopia (11740 N.W.
West Rd, Portland Oregon 97229, (503) 645-3253) that contains lots of good
information on the original Big Board, and I suspect that they will have
information on the Big Board II. (I do have the magazine, and I find it to
be very interesting reading!!!)
