Isaac Traxler's Museum
I have been collecting computer hardware for a number of years
with the hope of either opening a museum one day or displaying
them one at a time at a local library. I am concentrating
primarily on microcomputers, their peripherals, and software.
While my wife is not real happy about the room all this "stuff"
takes, she does concede that it is a worthwhile cause, so if you
have old computer equipment or software, please consider donating
to my museum. This is not a profit based scheme, it is merely
an effort to save a little history that is quickly disappearing.
Currently I have 42 systems and 14 printers in
the museum.

Discussions of Selected Systems
The selections below have been written by Isaac to provide some information
about some of the systems.
The Tektronix 4051 is a Motorola 6800-based micromputer. Most versions
came with 16k of memory but could be upgraded to 32k. The machine came
with BASIC in ROM (supported variable names of a letter, a letter
followed by one digit, and a letter followed by a $ [for strings]; all
numbers were stored as real with 10-byte precision). This system includes
a serial port and an integral cartridge tape drive (600k per tape). These
systems also had two expansion slots that could hold I/O ports or ROM packs
(Matrix functions, editors). These systems also had a screen dump port that
could be connected to a behemoth device that imaged the screen on heat
sensitive paper (I have one). I also have a spare cpu board. the systems
also included a GPIB (General Purpose Interface Bus[also known as HPIB])port.
I have one external GPIB tape drive. The most unique thing about this system
is that it came with a classic Tektronix "Green Screen" (high resoultion
vector display). This made it a tremendous graphics tool (the first
computer I ever used).
A follow up to the 4051 was produced (4052) that was identical except
significantly faster. This was accomplished by producing a custom cpu
board based on multiple bit-slice technology cpu chips and then emulating
the Motorola 6800 cpu.

Also known as the VK-100, the GIGI was an early effort by DEC to
produce a personal computer and a usable graphics terminal. The GIGI,
like most PCs of the time, came with BASIC in ROM. Also like most
of the PCs from back then, it had its own graphics standard (ReGIS).
The GIGI looked vaguely like an Apple II (much wider because it includes
a standard VT100-style keyboard, but much less shallow because no slots
were included). The GIGI could be connected to composite video or a
RGB (BNC) monitor with sync on Green. It had a resolution similar to VGA,
but displayed 80-column acceptably via composite to large TVs (we used
them in classrooms for demonstrations).
The GIGI emulated a VT-52 plus a little more but not quite all of a
VT-100 (if it had, it would have been a wonderful box). As TPU came
along, the GIGI became very obsolete.
