Hi Tony,
I worked extensively in Dap16 in the 70's and
still
have a working H316 at home plus plenty of spares.
What a strange posting...
At the moment I have three H316 machines sitting around me. One (my
first and official one) is a 16K machine with PTP/PTR, ASR, RS232 (!),
"parallel channels" (docs needed!!).
The second unit doesn't actually belong to me - but it will. It is a 4K
machine without any options. Just the processor in the box, no peripherals.
The third machine is a H316R with 16K and ALL (!!!!!!) boards (mem
lockout, mem exp blah blah) installed in the CPU card cage. And some
unknown peripherals. Could be very special.
I tried the memory and standard CPU boards in my first machine. Except
that one F-04 on the ASR pcb is mechanically damaged (lid off, bonding
wires broken), all cards and the memory work fine. I just ran more than
100 rounds of CCT-4 without stop today.
The chassis and all the rest haven't been tested yet. There's a very
tiny PSU inside the machine. It is nearly unserviceable and I have no
schematics. A very compact block with multiple separate small
transformers inside. It could be a switching PSU (date code 1972) or a
400Hz power supply. Both are ugly. It is 110V according to a warning sign.
Further I have a Honeywell 4210 "very low cost" tape drive unit, an
empty H316 expansion box with PSU and the tape drive controller.
But the tape drive needs some vacuum switch magic and some stupid idiot
has stolen all the cards out of it. So I will have to construct
something someday...
--> I have NO spares :-(
And I need at least an F-04 for my third ASR33 board to work again.
Beside that damage I have not yet had any failure on one of the
machines. Of course, the PSUs are part of another story. They needed
some service. But I repaired three units. And one is in badly working
condition, still has to be fixed (Just one small capacitor failed in the
three other units..).
What do you think about taking some pictures? If you don't have the time
or will to put them online, I could do for you.
What docs do you have? Please supply an index. Some docs are urgently
needed. Same for software.
I have (most important stuff):
FORTRAN IV (source on PC, objects, original listings)
DAP-16 (objects, SLSTs, original listings)
CCT-4, CMT-5 (SLSTs, original listings)
BASIC SLST
Original and custom IO libraries (made routines for my printer
interface), with listings and partially machine readable sources
CPU schematics, manuals, blah blah
Same for DDP-516 (!)
etc....
I appreciate to get in touch with every X16 owner around the world!
Known people with more or less working X16 equipment:
Adrian Wise (H316, DDP-516)
Bill Maddox (H316)
Michael Umbricht (H316)
Sergio Izquierdo Garc?a (H716)
Erik Brens (DD-516 parts, might still sum up to several complete
systems. Is selling them)
Would nice to hear from you.

Best wishes,

P.S.:
I have attached a 16K auto-start SLST of my mandelbrot fractal program.
The SLST is made using my selfmade DAP-16 written PAL-AP replacement (no
4/6/6 code, only PTR support, autostart facilities). Try to boot it on
your machine. Or in SIMH. Both should work... :-)
