I have been trying to decide the best way to get images into digital form.
Naturally, a digital camera is one way, but not the only. There's also the
photo/scanner method, camcorder/video capture, and probably others. As I
see it, the pros/cons are:
DigCam: + Easy to use, convenient
- Expensive to buy, somewhat limited capacity,
no hard copy of images (except printer output)
Photo/Scanner: + Hard Copy, can be used for other stuff too
- Film and Developing can be expensive, takes time
Camcorder: + Easy to use, Allows for selecting the right image
from several views
- Video capture hardware/software isn't cheap
So, does anyone have thoughts on which is best? I'd like a scanner for
other things, but they're expensive too. There's also the question of 35mm
vs. polaroid and type of scanner. (Not to mention where the heck would I
put it!) I've got a camcorder and my girlfriend's mac supposedly can do
video capture as is, but I've got to find software and figure it out.

Yes :-)
I remember the PCWs we used to have at school. They had small scanning
devices that replaced the print head on the printer. The computer
would make the printer scan the entire sheet of paper, line by line,
and in this way it built up the image...
Not the fastest of scanners, but fun to watch it go!

In the interests of getting an old DEC PDP-11 running, I've got an STC
9-track tape drive here, a model 2921. This is, apparently, one of the rare
few that StorageTek (aka, STC/Telex) manufactured with a Pertec interface
vs. their own.
Based on conversations with a company that still maintains these old
beasts, it appears that the CPU card has gone bad. I'd like to at least try
and confirm this by swapping said card with a known-good one.
So... anyone own a 2921 that they don't mind it being used as a guinea
pig? ;-)
Thanks in advance.

I have found what seems to be a decent supply of eproms. I was looking at
an old 2400 baud fax modem for my pc, and noticed that it had what looked
like an eprom on it. I pulled the chip and peeled off the label, and it was
a 27256 eprom. I also bought a 2400 baud modem at a thrift store for $2.00
and it had a 27128 eprom in it. This was cheaper than buying the eprom by
itself. I paid $3.00 for a 2764, and didn't even price a 27128. I am going
to start picking up all of the old cheap, almost worthless modems and
grabbing the eproms out of them. You can probably pick up the modem for
less than the price of the eprom that it holds. If anyone else knows of a
cheap source of eproms or other chips, share it with us.

No. first it was not an 8080 replacement. Though it may have subbed for
8085 as they were very similar. Two the system had to be configured to run
8088 code(wich is not 8080 or z80 compatable.
I had done this to an 8085 system as the signals from the 8088 are the 8085
are very close.
The extra plug was likely the remaining 4 address lines (16 bit vs 20 bit
addressing).
If I had one I could trace it out and regenerate the schematic.

Hi,
New here but here goes...
The module was a "upgrade product for those wating a 8088 and having only
z80 cpu. By unplugging the z80 and putting in the card you could run 16bit
apps.
qdos was not a clone it was and outright disassembly of CP/M80 v1.4 and
reassembly to 8086/8.

I have available several PC100B Memory Extension cards for the Rainbow
for giveaway, or for trade if you have something that interests me.
At the moment, the cards are unpopulated, but you can generally find
256Kbit chips to fill the board for about a $1 junk PC card. (A fully
populated board has at most 3 banks of 9 256Kbit chips for a total of
768K and a system total of 896K.) I can provide a copy of the memory
configuration pamphlet.
I will give preference to anyone who has something to trade, but feel
free to ask even if you don't. If you have something to trade I will
even go out and find the $1 junk board and populate the card!
Here's what I am looking for:
1) BCC17 cable for use with a VT241 color monitor
2) Documentation for Rainbow Concurrent CP/M-86, especially programming
references.
3) Venix/Rainbow software and documentation.
