I've been making a debugging ROM board to test out the various
parts of the KIM-1. It is based on taking over the KIM at reset
and running test.
So far I've got two test working. One is a basic, is it running test
that just blinks a light on the debug board.
The next is a test of the first 1K of RAM.
A little tricky to do without RAM.
I expect to write some more for the RRIOT ics.
If anyone has interest, they can follow me on the Vintage
Computer Forum or contact me here.
The board has 3 ttl ICs, a 2764/27128 EPROM, a couple
LEDs and a dip switch. Also a few pullup resistors and capacitors.

Nostalgia...I really liked the NCD 19 I used many moons ago.
Reasonably snappy at the time, nice mono screen, quiet. Funny enough
I recently resurrected an NCD Explora 701 (much later MIPS-based
xterminal). It's wildly faster than the 19 (with 10/100 enet instead
of just 10), but it's interesting to see how far modern X
implementation has diverged from NCDs time: 8-bit pseudo-color is a
showstopper for a lot of things, various desktops (Gnome, KDE, etc.)
break in strange ways if they run at all, lot's of contemporary code
has issues on 64-bit systems (like my old xview/olvwm code). TWM
still works fine, as does the butt-ugly built in NCD Motif-ish window
manager. Haven't had much time to work on it, but I'd like to get
something like i3 running. I bet Mouse can add more color commentary.
Reminds me...need to see if I can still get the Mouse terminal
emulator to run. Probably also need to get an SCO ODT or SVR4 VM
running for that old school feel.
I know I've got at least one 3.x release, but not sure which one or
what's in it. FWIW, I've also got some 4.x, a 5.0.x and 5.1.x;
running 5.1.140 on the 700. I'm in Dublin until next week so won't be
able to check until then. Ping me directly if you don't hear from me
by, say, Thursday.
P.S. - If anyone has an NCD 700-series or HMX (esp HMXpro24) they
don't want, let me know.

Just on the off-chance... does anyone have schematics for the Perq 1
portrait monitor? Mine is sick... and there are none on bitsavers. On
first power-up there was a faint raster pattern but that quickly
vanished and now there's no sign of life from the tube heaters...
Thanks

In a box of my old stuff, I found a copy of the Mt. Xinu calendar for
1993, the last year that they did a calendar, and scanned it. Some of
you may fondly remember the Mt. Xinu calendars so I am hosting what I
scanned so folks can download it. It can be found at:

Hi all
I'm trying to resurrect my NCD19 for vcfe.ch but I can't find the firmware
for it (I have half a dozen different versions of NCDware, but most don't
contain the boot images, and none have the binary for the ncd19, only
ncd15b, ncd19r, ncd19c etc. which don't work). And all links I find on the
internet are dead ;(
I appreciate any help tracking that down.

One of the DC filter capacitors has gone open circuit in my Tektronix 4051.
It is a SPRAGUE 9600 uF - 30VDC with a little bit unusual foot print.
It might be common for other Tek equipment.
Google turned up one Ebay-hit for a completed auction but that's it.
Anyone has a reliable source for this type of capacitor:

The interest in video terminals has been awoken again, and I am again searching for one.
I like the look/size of the VT220s, very nice and compact!
Anybody have extra DEC or IBM terminals in Toronto (Canada) ? I?m probably somewhat interested!

I wanted to see if anyone has any more information or software distribution disks
than what I just put up on bitsavers under tsc and gimix. I have a hard disk image
for the GMX Micro-20 that I just bought on eBay, but no distribution floppies.
I didn't realize that the 68K version was so uncommon, since the 6809 version seems
to be everywhere.
The person working on Integral PC emulation in MAME asked for it, so it's up now under pdf/hp/hp150
Unfortunately, what he was looking for was info on the graphics ASIC, which isn't really talked about at all :-(
