remember that at the time the PS/2 came out IBM was trying to re-assert
their lead in the industry (they largely failed). they decided to move to
a completely new architecture which they hoped would set a new standard
(e.g. 3.5" floppy; Microchannel; VGA graphics). the microchannel failed
because they tried to license the technology, but people found ways to
breathe life into the old ISA bus instead. the small floppy and VGA were
obviously successes, but IBM underestimated the need for backward
compatibility to the larger floppies (obvious in hindsight).

I'm glad to see that I'm not the only one frying Disk II's although I only
seem to fry the 74LS125's on the drive.

The Commodore 1084 is a versatile, inexpensive monitor on the used
market. It has composite, Y/C, analog and digital RGB inputs with
front-panel switching, as well as built-in audio (the 1084S is stereo).
The Commodore 1702 is an older model that should be even cheaper. It
has composite and Y/C connections switchable only on the rear panel, and
monaural built-in audio.
I'm sure both of the above were available in PAL versions, probably with
the same features.
Many older systems can be wired to use Y/C connections (e.g. Atari 8bit,
C64) by using a custom cable on the video DIN connector instead of the
Ch3/4 TV output. Y/C connections (also known as S-video) will yield a
_much_ higher quality picture. The Commodore monitors use dual RCA
connectors instead of the mini-DIN4 connector more commonly associated
with S-video, but electrically it's the same. If you had a newer system
with S-video output (e.g. PlayStation/Saturn) it would be simple to make
a mini-DIN4-to-dual-RCA adapter cable.
I use a Commodore 1084S for my Amiga, Atari ST and IBM CGA/EGA
applications; a (ultra cool) Samsung GXTV (http://sosimple.com/gxtv.htm)
for various systems, including those that have only Ch3/4 output (e.g.
Mattel Aquarius, Timex-Sinclair ZX) and for watching TV in the computer
room :), and a Sony PVM-2030 broadcast stacking monitor for the modern
video game systems.
I'd like to find a Sony GVM-1311Q, which is a 13" monitor that accepts
composite, Y/C, digital and analog RGB, the latter at up to 1024x768.
That covers just about everything except Hercules Mono.

Recent finds...
Been adding to the Atari collection, last weekend snagged a 410 tape
recorder for 99 cents, noticed a bit of rattling and discovered a
plastic part had fallen off the rewind key mechanism (it triggers a reed
switch, probably to mute the signal when rewinding.) glue or tape
should fix it. Now all I have to do is find those games I have... I
think I have a Telengard tape that has atari on it, I wonder how it will
compare to the 64 version... And I also have an Automated Simulations
game somewhere (the science fiction one like apshai?), it could have an
Atari version on it as well...
I might have a possible candidate for a power supply for the growing
Atari collection (from a thrift store with a table full of various PSs,
and mention of boxes more in the back, gotta check there more often!),
it is a 9V AC 1.6 amp supply... so, how much difference is there
between 1.6 and 1.7 amps? The least rated supply (listed in the Atari
FAQ) to run on an 800/1200XL is a 1.7 amp, can the 1.6 cause problems?
(I have yet to try this as the plug is the too small and I will have to
solder on a more suitable one for it to work.)
Also got an 810 drive, did a power test tonite, the disk went through
a 'seek' of some sort (still one PS and no disks, so it's best I can do
for now) Now I have disk drives that match the 1200XL and 800!
Speaking of the 1200XL I mentioned earlier the keyboard was not
functional, a fellow user on the comp.sys.atari.8bit newsgroup suggested
checking the keyboard connector, and by-jimminy, it was loose! (Now who
would open a perfectly good computer...well..ok, who wouldn't open a
perfectly good computer. *grin*.)
Books,tapes,disks are nowhere to be found for the Atari (at thrift
shops/book stores/flea markets), so far (since a month or two ago) not a
one spotted, and I thought Commodore books were hard to find.
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Monochrome monitors are pretty cheap out there, picked up a basic
Zenith green screen for someone for $2.95, saw a few more similarly
priced.
-=-=-=-=-=--=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
My best find of the week: one thrift store had a 128D unit sans
keboard (a 128D is a Commodore C128 computer with built-in 1571 disk
drive, latest ROMs, and 64k video RAM) for $7.00. I figured it would be
a great 'parts source' for my flat C128 (which has only 16k VRAM and old
ROMs), I assumed the 128D was DOA, only to discover it is functional,
the drive seems ok too! (booted a CP/M system disk and Renegade, two
disks with 128 boot sectors I knew of). Now I'm gonna have to
scrounge/hack up a 128D keyboard. (dang it all!)

I got a couple LDs from thrift shops the first ($20) was the great
grandaddy Magnavox 8000, still has major tracking problems but it can't
interface to anything anyway.
The second ($9.95!) is a Poineer 6010? Anyway, it is an 'industrial
grade' LD player (had an Armstrong Flooring disc in it). I have some
articles for LD interfacing: one for the VIC-20 in a 1982 COMPUTE! and
one I think for RS-232 in a 1983 BYTE; but this LD player already has an
RS-232 inteface built-in so that point is moot... I am waiting to bail
it out of repairs (very minor ones fortunately). Anyone got a Dragon's
Lair LD lying around???

Still no joy on the Apple II+ boot problem.
The machine appears to definitely have 48K RAM; at least the NEC chips
have "416" on them. Any way I can tell in BASIC?
I have 3 disk controllers and 3 drives. The disk controllers have 2
different ROM versions; one is half copyrighted 1979 and half 1981,
while the other is all 1981. The card model is 650-X104. There's
another ID number, one is 820-0006-02 and the other card is 820-0006-D.
Help!!!!

I'm fairly new to the collecting scene and I'm looking for a monitor I
can use with some of my systems. I'm mainly interested in the 8bit home
computers, spectrum, c64, atari, dragon, bbc etc
I'd like to know if there is a particular type of monitor that can be
used on the above machines. I'd like to buy, say one, I can use with all
of the above.
I know there seems to have been a few different methods used in
producing the video signals and, from reading newsgroups, I get the
impression that it is sometimes possible to select video outputs/monitor
inputs such that, even if the monitor is not directly compatible, a
reasonable result can be obtained.
Any pointers would be greatly appreciated.
