Behind in my email, but I note that the usual representation is that Al Gore “created” the Internet.  The ARPANET was something else (different protocols) and much earlier.  Al Gore didn’t make it into Congress until 1977; the Senate in 1985.  ARPANET was very much alive by the early 70’s.  Al Gore turned 22 in 1970 … just not precocious enough!

Not to take anything from the HP 2116A, but Computer Control Corp's (CCC) DDP-116 is generally credited as the first 16-bit mini. My main source is the Computer History Museum and the book "A History of Modern Computing," which says the DDP-116 was introduced in October, 1964. Although another source says it was introduced at the 1965 Spring Joint Computer Conference, here's a PDF data sheet from Honeywell (which bought CCC), that's dated September, 1964:

http://www.ddp116.org/products/ddp116/ddp116.pdf

I believe the HP 2116 was introduced at the 1966 Fall Joint Computer Conference by HP's Dymec division (again, using the Computer History Museum and my own HP9825.com as references). The DEC PDP-11 indeed came later, in 1970. It was third in the 16-bit race.

I actually designed and built a DAC card for the DDP-116 machine in the summer of 1973. It had served as a control computer to make cigarettes for Brown and Williamson before being donated to the Speed Scientific School at the University of Louisville. Of course a successor based on the same ISA, called the Honeywell 516, served as the IMP (interface message processor) for the original Arpanet that Al Gore created. That same Summer, I was introduced to the original Star Trek game written in Basic running on an HP 2100 series mini and a Teletype. This sealed my fate. I could work nowhere else but for the company that had made that computer. Exactly two years later, I joined HP's Calculator Products Division, which was making the 9830 at the time. It too could run Star Trek, in Basic.

Hi Paul

The MACRO/1000 Manual (92059-90001 Macro-1000 Reference Manual E1292) Chapter „C“ contains  the code compatibility matrix in between MX and A-Series.

About 21xx I have the Reference Manual. For 2100 and older I have to investigate the comparison. Currently I haven’t a list for this. Are you interested ?

Based on marketing literature I infer, possibly erroneously, that there is some coherent relationship among the instruction sets supported in all members of the HP-1000 family of processors: 21xx-series, 21MX-series, L-series, and A-series.

 

Is that correct?  Does anyone know where the relationship(s) are documented?

 

Have drawn a blank sifting through the HP Computer Museum documentation, and general search.  All that I find are scattered, general claims of software “upward compatibility”.  It’s not clear whether they mean binary compatibility or something else..

Re: 9825 I/O slot power budget?

Steve Leibson
 

The spec for the 5V bus on the 9825 I/O slot was 500mA. That's a number I recall off the top of my head. I doubt you'll find it written down anywhere. It was not that standardized and only half a dozen of us in the peripheral and I/O group needed to know. It was a real bear finding a microcontroller back then that could run from half an amp.

Before anyone asks, the +/- 12V spec for the I/O slot was 50mA for each supply.

A quick update to close this out.

I finally got round to using the extender boards to see what was going on inside this thing.
Started with RAM Bank 0, all the strobes and address pins looked to have sensible signals so I concluded the sundry drive chips were probably ok and guessed it was likely a stuck bit or something on one (or more) RAM chips.

Given the error code was 3080 and the service manual says 30XX is Bank 0 RAM and claims last two digits in an error code give an (unspecified) clue as to the type of error I took a chance and swapped out the '8th' RAM U39 and everything sprang into life.

With the addition of a couple of 'N' cells for the battery backup, all errors cleared apart from a POR '1000' boot failure indicating a touch screen issue, likely just a blocked beam or dead LED as actually all the touch buttons used by the P.A.M. screen seem to work ok.

Just formatted a 20MB 9133H hard disk successfully and have loaded and run GWBASIC so I reckon I'm close to having a working system?

If anyone need extenders for a 150 I have some spare boards.

A quick update to close this out.

I finally got round to using the extender boards to see what was going on inside this thing.
Started with RAM Bank 0, all the strobes and address pins looked to have sensible signals so I concluded the sundry drive chips were probably ok and guessed it was likely a stuck bit or something on one (or more) RAM chips.

Given the error code was 3080 and the service manual says 30XX is Bank 0 RAM and claims last two digits in an error code give an (unspecified) clue as to the type of error I took a chance and swapped out the '8th' RAM U39 and everything sprang into life.

With the addition of a couple of 'N' cells for the battery backup, all errors cleared apart from a POR '1000' boot failure indicating a touch screen issue, likely just a blocked beam or dead LED as actually all the touch buttons used by the P.A.M. screen seem to work ok.

Just formatted a 20MB 9133H hard disk successfully and have loaded and run GWBASIC so I reckon I'm close to having a working system?

If anyone need extenders for a 150 I have some spare boards.

9825 Manuals Available

Edited

I've somehow managed to acquire a surplus of 9825 manuals. I have 3 spare copies of the Operating and Programming Reference, 1 spare copy of the I/O Control Reference and 2 copies which combine the Operating and Programming and I/O Control Reference into a single binder. All the manual contents are in very good condition; the actual binders vary from good to not-to-bad.

They weigh about 5 to 8 pounds in a box; $10 each including shipping in the US via Media Mail.

Looking for informations about vintage circuits uPD135, uPD106, uPD102 made by Hitachi or NEC. Circuits are in dual-in-line packages, maybe TTL (not sure). Thank you for any suggestion.

Can't help you source any 12103L boards, I have never had any. But
that makes me wonder:

Are there many members out there who have or have had A400 / A600 /
A700 systems, and have any ever tried converting a 2MB 12103K board
into a 4MB 12103L board or an 8MB 12103M board?

It appears that could be done by populating another row of 17 TC511000
1Mx1 DRAM chips plus a bypass cap per chip to go from 2MB to 4MB, or
three rows (51 DRAM chips) to go from 2MB to 8MB. There is also a
PAL16L8 that differs between the 2MB, 4MB, and 8MB versions that would
need to be changed. The source code and JEDEC files for those PAL16L8
is available so that shouldn't be an issue.

The worst part of trying to do such an upgrade would be removing the
solder from all of the through holes so that new chips could be added.
