Not a COMPUTER but I have a Pro-log M900 EPROM burner that has a second source INS4004 on the board. This isn't my M900 (my INS4004 is white/gold), but here is a view of the board/chip: http://www.wolfgangrobel.de/programmer/img_m900/m900_06.jpg

Don't know about commercial products. But a classmate of mine got Honors in Independent Study for a project where he built a useable general purpose computer out of a 4004, plus a boatload of other stuff. It filled a wire-wrap panel board about 8 x 10 inches. He wrote some software for it as well, and took it to a summer internship at one of the National Labs (in the Midwest -- Argonne?) where as I understand it they liked it enough to ask him for a copy of the system. He graduated in 1975, so the work was done in the year or so leading up to that.
One complication was the terminal I/O (Teletype 33); originally he had a bit-banging interface for that, which isn't easy on a 4004. At some point he finagled a UART chip out of one of the DEC field service engineers, I think that was one of the first single chip UARTs, used in the earlier DEC PDP-11 terminal adapters.

what about that intel 3000 bit slice thing is it almost a microprocessor yes no and why? Ed#

No. 2:
Texas Instruments applied for a “computing systems CPU” in 1971 and awarded a patent in 1973. The question though is: did TI have a functioning processor based on the TMS1000. Not sure if they did!
No. 3:
“In 1969 Four-Phase Systems built the 24-bit AL1, which used multiple chips segmented into 8-bit hunks, not unlike a bit-slice processor. In a patent dispute a quarter century later proof was presented that one could implement a complete 8-bit microprocessor using just one of these chips. The battle was settled out of court, which did not settle the issue of the first micro.”
No. 4:
Is this the first microprocessor?
Here is a source:

No. 5:

It seems the answer depends on what is a microprocessor...I suppose when it comes down to capitalism patents count more than anything else!
Happy computing,

The 4004 was definitely the first commercially available single-chip CPU
on the market, but if you include multi-chip LSI designs, the lines get
blurry.
I just pushed two additions to https://github.com/pkoning2/decstuff :
In "patches" a new patch for the DEUNA driver. This fixes a problem seen when doing user (as opposed to DECnet) I/O, as well as two errors that show up when using units beyond the first.
Directory "ntp" is new. This is a simple NTP protocol client for RSTS, which will synchronize the system clock with an NTP server on the LAN. It includes handling of timezone rules, so the right thing will happen at daylight savings time (summer time) boundaries. The clock is maintained to the full RSTS resolution -- typically 1/50th or 1/60th second, but can be as low as 10 ms if the KW-11/P clock is used.

I'm working on some code where it would be handy to map the top of the I/O page along with the bottom of physical memory. An obvious hack is to point the APR to the I/O page address needed, then set the length so that the address modulo 2^22 also covers the low memory range.
It seems from the architecture manual that this would work, and SIMH seems to do this (since it adds VA and PAR then masks with a 22 bit mask). Would this work on real hardware?

Folks,
Trying to reduce the weight in my loft and I would like to donate my HP
Photoplotter to a good home.
. Photos of the plotter and some sample plots are on my OneDrive here:-
https://1drv.ms/f/s!Ag4BJfE5B3ongspXY7zySSZsDj-WMg
It has both serial and IEEE interfaces and uses HPGL like the GP and Roland
pen plotters.
The plots on there are the samples built into the plotter taken on a Fuji
XE-1 digital camera and are cropped because the Fuji does not have a full
frame sensor.
The tube is actually a white tube and the colours are generated by rotating
colour filters.
Its powered by a 68000 and you can see the various boards in the pictures.

Also had one other query. I will now keep things private...

I don't think I have any paper manuals.

I should have said the plotter came to me from France packed in expanded
foam. I think I may still have the packing.. I will check and report back...

OK I have shipped an IBM 3174 screen controller to Europe, and a E-Prom
programmer to the USA so I may also be reasonably experienced...
