[vcf-midatlantic] ADM3a parts at System Source March Workshop...

[William Sudbrink]

Hi,

I will be at the System Source Workshop on March 30,31.  I will be 
bringing a bunch of ADM3a parts, including:

(Names are to help identify pictures, web site below)

Chassis1 - this blue chassis is an original, serial number 6961 with the 
115 volt transformer.

Chassis2 - this blue chassis is a type 2 (with the extra venting and 
cardboard interior), also 115 volts.

Chassis3 - this brown chassis is a late type 2.  It has no speaker (the 
speaker was soldered to the mainboard in late type 2). This is a 230 
volt transformer unit.  Its fuse holder and switch were donated to 115 
volt machines a long time ago. Otherwise complete.

Clean board - this mainboard has no keycaps but is otherwise physically 
complete and in good condition.  It powers up to a cleared screen with a 
cursor but shows no activity on key presses.  Note that the key switches 
are present on the board.

Dirty board - this mainboard has seen better days.  There is some light 
corrosion on some chip pins and component leads.  It has some but not 
all keycaps.  Definitely does not work as it stands. I got it this way 
and only took it for the lower case ROM which is being used elsewhere.

Good monitor - well, good in that it works and has no visible burn in.  
But... it has terrible cataracts.  It has not, fortunately, started 
leaking.  Complete with driver board.

Zenith monitor - Has a little screen burn and a couple of scrapes on the 
glass.  I have no compatible driver board for this monitor.

Mounting hardware - these mounting "ears" and band were taken from a 
Ball CRT with a broken neck.  Could be used to mount a different CRT in 
an ADM3a.

Driver1 - This is a complete driver board for a Ball CRT. Unfortunately, 
the anode cap was smashed, but I am including a replacement that will 
need to be installed.

Driver2 - This CRT driver board is incomplete.  It has had its HV 
transformer taken.  I _think_ this is also for a Ball CRT but it is 
different from driver1.  Could be useful for repairs.  Bracket for 
mounting the HV transformer is included.

Finally I, of course, would like some money for this stuff but more 
importantly, I do not want to take any of it home with me!  I will deal 
and if it gets late in the day and you're nice, you may take it home for 
free.
