> A SuperKIM? What's the difference?
The SUPERKIM is a neat little board, based on the KIM
design, but with a real lot of enhancements. It uses
the same 6530-002 and -003 chips to get the KIM software
the same keyboard And connectors. But unlike the KIM
all ICs are on sockets, free sockets are already provided
for 6 more 2114 to get 4 K of RAM (like on the SYM)
four sockets for (E(P))ROM (up to 16 K), four sockets
for 6522 VIAs (one already in place), a interrupt
priotity logic, buffered busses, wire warp connectors
for almost anything, complete memory decode, and last
but not least a huge prototype area and a 5V and 12V
regulator, so you only have to add a transformer, instead
of designing your own PS. And the LEDs are already
atop a seperate PCB (like the keyboard, but here is
no difference to the KIM), so a 'distant' mount of
keyboard and display is easy.
On the backside, the _list_ price of 395 USD was
almost twice the street price of a KIM and in
the same region of the AIM street price (~400 USD
in 1978/9). Shure, for a pure controller system,
you don't need the ASCII keyboard, ASCII display
and printer, but instead more I/O and interrupts,
but the price was still impressive - I don't know
if they sold a lot, but I guess, since the company
had payed advertisements over more then one and a
half year.

Hi,
I picked up a GRiD Model 1900 pen-based DOS machine today. HSC Electronics is selling
them for $20 each here in Californie. I haven't found much in the way of websites,
pictures, etc. of this machine. Does anyone know of any out there?
What I know so far is that they seem to be V20 powered 2 mb RAM based machines with
little expandability but a nice LCD display. It has a semi-standard [compatible but
weird pinout] port for a keyboard. There is a port on the side that I hope is a serial
port and not a CGA or some such thing. How do you get data in and out of these machines?
I was wondering what the little door on the bottom of the machine is. Someone in past
e-mails on the net mentioned that it was for an IDE hard drive connection. Might this be
true?
I haven't powered it up yet as I have yet to order a power supply for it [Monday] but am
intrigued enough to pour a few bucks into it to see if it works properly.
With piqued curiousity,
Thomas

This is very true. In the window of around 75 through now NEC, Hitachi,
Fujitsu, Yamaha and others have produce their own 4bit data path single
chip cpus. NEC had in the early days the uCOM-4 series and later the
uCOM75 series. While each had some similarities to 4004 they were not
compatable. They were also most widely used in games like Einstein,
Simon, VCRs (timer), Microwave ovens to name a few.

That would run nicely on my M76. ;)
The only reason that wasn't on my list is I have some nice z80 systems.
I wouldn't mind having that as it would be one more reason to use the vax
more.

OK, point taken. EHT wire is lighter and no more bulky than test lead
wire, though, unless you want to measure currents bigger than about an amp.
FWIW my Fluke only comes out of its rubber holster when I need to change
the batteries (seldom) or the ammeter fuse (far too often!)
Besides, if I can fly all the way from Birmingham UK to San Jose CA with a
Tektronix 4052 (80 lb) in my baggage...

Agreed 100% (as Tony would say). In the electricity industry, safety
procedures require you to test an EHT meter on a known good source before
_and after_ the measurement. While that's impractical if you're flying
around with no more test equipment than you can fit in a briefcase, a
useful principle to follow.

I agree but that adds weight and bulk to an already overstuffed and heavy
tool / parts case that I will not check through airline baggage. It is
something that I have to do only a couple times a year so I realize I am
taking chances and after the bite of 8Kv I tend to be even more careful. I
have some 40KV rated test lead which would work but it is bulky for use on
the road.
Keep in mind that I used to be in 2 to 4 cities a week. 99% of the time
with airline flights between each city. Weight and bulk is a BIG
consideration then.
The most important thing I was trying to point out with the first item in
that post is NEVER assume the meter is correct. It will bite you.

Servus,
does anyone of the members own a SuperKIM or know
a surviving unit ? I would like to get more informations
(and maybe the computer :)

Fujitsu (like NEC and a lot other companies) is
still producing several lines of 4 Bit controllers.
They also design _new_ 4 Bit singlechipers. But
AFAIR these are not compatible to the 4004 in any
way.

Especialy, are they able to do fast foreward, backward
under computer control ? Or maybe reverse read ?
Could be a great thing, Iand I would like to get a few.
Did you already fix a price range ?
