Retrocomputing
I'm interested in old computing devices. Mostly machines made before 1982,
but with a few exceptions. Some of these machines are well known and were
very commercially successful. Others have faded into obscurity, despite
having advanced the state of the art.
I've tried to provide some technical information of a few of the interesting
machines. Unfortunately I don't have very much time to spend on this
endeavor.
Generally speaking, nothing listed on this page is being offered for sale,
except perhaps the items in the trade section.

The Central Research Institute for Physics (KFKI) in Hungary made a series
of computers called
Stored-Program Analyzer (TPA). Many (but not all) of these machines were clones of DEC machines.
DEC module lists are available from:
- Field Guide to Q-Bus and Unibus Modules
originally maintained by Ronald Copley, this was stagnant for some time but now seems to have acquired two different maintainers:
- Yet Another DEC Module List of modules not for Unibus and Qbus, maintained by Zane Healy

- Calculating devices:
- Friden EC-132 desktop electronic calculator
This was one of the early electronic desktop calculators, ca. 1964.
It is very similar to the Friden EC-130, with the addition of a square
root function. It uses RPN logic and displays the four-level stack
on a small CRT. There is a mechanical interlock to prevent the user
from pressing keys while the calculator is "thinking". The logic
is implemented with discrete transistors, and the memory is implemented
by a magnetostrictive delay line. Originally sold for $1950, about
the same price as an automobile.

- Elf II —
The original Elf construction articles ran in Popular Electronics
in 1976-1977. The updated Elf-II design has a hexadecimal
keyboard wtih an MM74C922 encoder in place of the data toggle
switches. The Elf-II design was published in Popuer Electronics'
"Electronic Experimenter's Handbook", 1978 Edition, and a kit was
offered by Netronics. The expensive HP hexadecimal displays were
replaced by more common seven-segment displays, driven by DM9368
hexadecimal-to-seven-segment latch/decoder/driver chips.
