Ummm.. No.. I have some cards lying around here so unusual
I couldn't identify them even with the case open, let alone by
physical inspection of the back panel, and a few I couldn't
identify even with the card in my hand.. For example, what
would you expect a double width card in the ISA portion of the
board sporting a pair of DB9 to be a video card, especially after
seeing onboard VGA?

This is an important message about the upcoming Vintage Computer
Festival 5.0.
Due to budget constraints, VCF 5.0 has been restructured. The event
will begin as scheduled with lectures beginning at 10:00am on Saturday,
September 15 at Parkside Hall in San Jose. All lectures will be given
on Saturday, ending at 3:00pm. At 4:00pm, the event moves to The Computer
Museum History Center at Moffett Field in Mountain View. There, the
Museum staff will host a tour and reception of the Museum's "Visible
Storage" warehouse. The tour and reception will last approximately
3 hours. After that time, attendees are welcome to return to Parkside
Hall to attend the California Extreme classic arcade show at a discount
VCF rate of $20 after 5:00PM or $15 after 7:00PM (with your VCF badge).
Please note that attendees wishing to visit The Computer Museum History
Center must register in advance in order to be allowed through the
security gate at Moffett Field, which is a United States military base.
Please continue reading for instructions on registering.
On Sunday, September 16, VCF 5.0 will continue at the Alameda County
Computer Resource Center (ACCRC) in Oakland, California. The ACCRC is
a non-profit organization that accepts donations of computers and
computer equipment, refurbishes old systems that are then donated to
schools and charities, and recycles the remainder to help protect our
environment.
All exhibits and vendors will be set up at the ACCRC's facility. The
ACCRC will also be selling a large amount of vintage computers that
they have accumulated over the years, as well as modern day PC and
Mac parts in their inventory. There will be tours of the facility
to demonstrate the various community projects that the ACCRC conducts.
The ACCRC is currently undergoing a budget crisis, so your attendance
on Sunday will help this fine organization that serves a worldwide
community keep its operation viable. All admission fees on Sunday
will be donated to the ACCRC. All paying attendees will receive a
donation receipt for their admission.
Admission for the lectures on Saturday is $12 per person at the door.
Tickets for a shuttle bus which will take attendees to The Computer
Museum History Center will be sold separately for $5 per person.
The bus is mostly intended to assist out of town guests without their
own transportation but any guest is welcome to ride the bus as well.
However, seats are limited and priority will be given to out of town
guests. Tickets will be issued on a first come, first served basis.
Please continue reading for information on how to reserve a seat in
advance.
Admission to the exhibit and marketplace on Sunday, September 16, at
the ACCRC is $10 per person at the door for adults. Kids 17 and under
will be admitted free of charge. Parking is ample and free, but we
want to encourage attendees to use public transportation such as BART
to get to the event. The BART station nearest the ACCRC is the
Colesium/Oakland Airport station. Shuttle transportation between the
station and the ACCRC will be running every 15 minutes. Out of town
guests who will be staying in the San Jose area can use the bus to
get to the nearest BART station. If you wish to receive help in
planning the trip, please send e-mail to <vcf(a)vintage.org>.
Here is a breakdown of the new VCF 5.0 schedule:

The changes in this year's Vintage Computer Festival are the result
of budgetary constraints brought on in part by the sluggish Silicon
Valley economy. We hope to be back to normal next year. But for this
year, we believe we have put together an event that will still satisfy
our loyal VCF fans as well as first-time attendees. If you have any
questions, comments or suggestions about this year's event, please do
send them to <vcf(a)vintage.org>.
We hope to see you at this year's Vintage Computer Festival!

Do you remember any of the answers? I'm curious...

SOunds interesting. The SAA5243 is much easier to find in the UK, I
think.
It is, I've had five 5243s and no 5246s from scrap TV's recently.
How compatible are the 5243 and 5246 in software (as in register bit
allocations, etc). Wildly different?
A couple of extra bits in the registers to set PAL/NTSC and free run (VCO)
and a bit for VCR which was a pin on the 5231.
Also a new register with status bits for sync type (525/625), data quality
and signal quality.
Software for the 5243 should run on the 5246 if you set all the unused bits
as per the data sheet.
It does, it also has the video output drivers on board so needs far fewer
external components.
Adding the SAA5231 to an SAA5243-based display is overkill unless
you
need the genlock capability or you also want to decode teletext
data. A
As all my teletext chips come from scrap TVs I don't bother removing the
5231, only the Safari control processor if it's fitted.
Lee.

1) An SAA5243 (for the UK/Europe -- I think the 60Hz-vertical
version is
the SAA5245) This is actually a teletext display IC for televisions,
and
is controlled via an I2C bus (2 wires). The nice feature is that the
If you can get the SAA5246 you can do either PAL or NTSC video rates
(software selectable).
3) Some way of generating a 6MHz clock. A 74LS04 + a crystal, for
example.
The 5246 has an onboard clock generator so you only need a 27MHz
xtal.
You get a 40*25 text display (upper and lower case) with
teletext-style
block graphics and serial colour attributes. Not bad for 3 chips and
2
port lines.
You can, with the 5243 or 5246, have either 8 pages of 25x40 or four pages
of 27x40.
Another advantage is that the 5246 has the video processor (SAA5231)
integrated so you can genlock your display.
Lee.

I found a Tektronix 465 o-scope today for $50 - it's missing probes, and
the owner was going to look for the manual, but I'm wondering if this
would be a good scope for hobby purposes?
The previous owner feels that it probably needs a good cleaning, like some
of the knobs.
Any insights?
