Also used on the AIM65 (and, IIRC, the VIC20)
BTW, Issue 7 of the AIM Interactive mag (available on Rich's site) had the
schematic & software (in Forth) for a very simple 2716/2532(2732) EPROM
programmer; 2 TTL & CMOS chips and two relays (!).

Fellow CCTECH'ers, especially those in the Bay Area,
I just got an E-mail from a fellow scrounger. It seems that, though Mike Quinn Electronics is indeed closing their doors for good, they will be having a big liquidation sale this coming week. Hours for the event will be Tuesday (the 7th) through Friday (the 10th) from 10:00 to 16:00.
Regrettably, I have neither the available time nor the budget to make the trip down. I would appreciate hearing from anyone who visits during the final week to hear how it went. Please give Jay my regards if you see him.
Keep the peace(es).

Found another box of TK50 tapes, so figured I'd ask again if anyone is
interested, contact me.
Also have a couple of external SCSI tk50 drives I could part with, and a
VaxStation2000, with a 19" vax monitor (monitor is probably
prohibitively expensive to ship, but anyone near CT who wants both, and
keyboard/mouse, etc, I'd give preference to parting with both together).
Also tons of 90M DAT tapes, if anyone is interested.
Also for anyone near CT, I have a compaq 1600, dual 600mhz cpu's, all 5
drive trays (one 4gig drive dead, but I think I have one to replace it
with), and I'll toss in a 3200-raid controller. Free to anyone who
wants to pick it up, or meet someplace. I'd consider shipping it if
someone wants to cover the shipping costs.
And a pair of Mac IIsi's, and three MacSE/30's, all with NIC's (at least
one of the SE/30's has NetBSD on it). Free, just looking to clean
house (keeping my quadra 650).
And anyone who might be looking for TEK service manuals, the old job was
tossing several xerox-paper boxes of them out, I'll try to make a list,
but if you're looking feel free to ask.
Also have some plugins for the 7000 series O-scopes, probably take a few
bucks for those, but I can certainly come up with a list.

Misunderstanding between
"unsupported = not guaranteed to work by the manufacturer" (KZQSA disk drives on VMS, HP-UX 11i on G70)
and "unsupported = will not work or is not likely to work" (KZQSA on NetBSD, NetBSD on G70)
My read of an earlier thread was that KZQSA was not likely to support multiple devices or fixed disks under VMS, rather than merely "HP will not guarantee OpenVMS to support all disks on KZQSA".
It would be nice if a definite distinction was made between these two connotations of "unsupported", but I suppose it would be a lot of bother for anyone trying to do that, especially the companies.

Hi
I think ( but I'm not sure ) that this spacing was
used for the bus connectors on the KIM-1 and the SYM-1/2.

I just busted a recent myth. . . connected my KZQSA up to a RRD42 and a IBM 0661 Winchester - worked just fine booting, mounting, etc under VMS 7.2. Slow, but functional. KZQSA supports more than one device and works with HDDs
The subject line does not cover this reply, but I think it is good to
keep the reply in this thread.
I ran the 5 diagnostics (ZR6A - ZR6E) for the RK611 controller, and
let each diagnostic run for 2 passes. They all reported no errors.
So, time to connect the RK07 drive.
Then I ran ZR6H, the first diagnostic for controller -and- a drive.
After some 12 minutes I got a print out of the controller registers,
(as I had before ...), but this time I looked a bit better at the data
and went through the meaning of all bits. In RKCS1 bit 15 CERR was set,
this is the Combined Error flag, and you must look at the other bits
to find the reason.
Then I found that the BSE, Bad Sector Error bit was set ...!
I wondered "is the pack I'm using good?", and mounted an other pack.
To cut a long story short: I am now booting the 11/34 from DM0: !!!
Again, I learned a lot about the hardware, but more important:
- do not assume the worst, the problem is often simple.
- if the system gives you data, have a *very* good look at it.
thanks,
- Henk.

Hi Bill,
Two suggestions:
Check out Evan Koblentz's list of museums: http://www.snarc.net/c-places.php
Also,
There's a pretty cool Historical Electronics Museum near Baltimore-Washington International Airport
that has a broad range of gear and exhibits: www.hem-usa.org . You can see on their site, that
many of the exhibits are Defense-related. They have different areas:
Fundamentals Gallery
Communications Gallery
Early Radar Gallery
Cold War Radar Gallery
Modern Radar Gallery
Countermeasures Gallery
Under Seas Gallery
Electro-optical Gallery
Space Sensor Gallery
My kids love it. We also use their facility for our yearly Robot Fest. Nice folks to work with.

I've heard that the Computer History Museum in Mountain View CA is a good one. Any comments? If
one had to choose only one (pre-PC) computer history museum to visit in the US, would that be the
one to choose?
Please provide leads to any other good computer museums in the US that have good hardware
collections. I'm interested in pre-PC computer history only. The history of IC technology
development also interests me and I'd enjoy hearing about any US museums/exhibits which focus on
that topic.
Thanks,
Bill

Relax. Yahoo! Mail virus scanning helps detect nasty viruses!
One thing I've been concerned about for a while is what seems to be the
lack of electronics building skills. *My* feeling is the desire to work
on this stuff is going away and I'm not sure why. I DO NOT BUY the
argument that components are so small now that nobody can build or hack
equipment anymore as I view that more of an excuse for not building.
It also seems that most (not all) of the people I know that collect
computers now (and used them in the 70's and early 80's) are fairly
competent at working on electronics.
Are kits at all desireable to build by newer entries into electronics
and computers? Or existing builders?
Comments?
