Subject: Simulating IBM serial port control?
Date: 13 Aug 92 17:16:59 -0600
Distribution: world
Organization: Memphis State University

  Here's an interesting question:

I'm thinking of buying a robotic controller card from MIT.
It's designed to be interfaced through an IBM serial port for code
transfer to the card memory.

Will PCTask or such handle the transfer okay?  (the code that performs
this is a modified C compiler specifically designed to use some special
libraries for actuator/sensor control and throughput... there is a 
seperate program that dumps the compiled control code through the serial
port to the robot.)

Any help appreciated,

I just bought a Conners 40sc drive....

my rpoblem is that I did not get any data sheet with it....

what I need to know is HOW TO CHANGE THE ID # OF THE DRIVE!!

THERE are 3 sets of jumpers.....

one back by the scsi connector which has 4 jumpers
one back (drive circuit board up SCSI at top) lower left corner
which has 9 jumpers which all look like they are on whith jumper that is
ONE piece.

and the last is in the right corner but the pins point sideways...
the 2 on the left are for the access LED then a blank then 4 pair and then
a single pin and the bottom....


can someone help me out and tell me HOW to change the device ID #

It's just to replace the whole power supply plus also replace a lot

3-4 kSEK, I don't know if it's cheaper now).

A much cheaper solution is to buy a 220-110V converter at Claes Olsson
(about 200 SEK). My PS gave in, though, but noone beleives it was
because of the voltage converter.

I would like to thank people who answered my questions, if you did so
by mail and didn't receive a reply, your mail bounced and I havent
had a chance to figure out why. 

Summary:

1000 keyboards cannot easily be taken apart.
 to remove the key actions to clean the contacts means you must de-solder
the contacts at the bottom of the key. this is not easy, and you can mess  
up the action rather severely. I personallly ran the keyboard through the  
dish washer (with a very tiny amount of liquid soap), but then my keyboard  
bottom was completely coated with hair, dirt and a couple of newly formed  
rare earth elements. This did not solve my problem (keys moved but did not  
cause "contact", in fact it caused the same problem on several keys.  
somebody suggested silicone, and since I had a can of spray silicone, (the  
very thin, drying kind), I shot the offending keys for several seconds,  
and then with generous pressing (banging?) of the keys, they all work. 

again thanks to all who responded,  sorry if I can't remember individuals
name, especially the one with the silicone solution, but thanks.

Hi Everyone,

my current project is to use my computer to control various real-world
devices.  I have hardware which connects to the serial port which lets me
send Amiga audio over the phone line and use a sampler to record audio from
the telephone line (the sampler is in the parallel port) and hardware which 
lets me decode touch tone signals from the telephone line which plugs into
the joystick port.  Unfortunately this use up the quota of ports on my 3000.

I can get a Commodore card (A2322) which has 7 serial ports, but serial ports
are less flexible that parallel IO ports.  

Does anyone know of a card which provides some general purpose bit
addressable IO ports for the Amiga?

Any info will be greatly appreciated.

Regards,

  Paul

It sounds like you're not using reselection.  This allows a SCSI device (like
a tape drive) to recieve a SCSI command (like FastForward) and then detach from
the SCSI bus.  Now other SCSI devices can be accessed.  When the tape drive is
finished it can reacquire the SBSI bus and continue.

I'm not familiar with the Supra controllers so I can't give you any specific
solution.  Check your Supra docs for info on reselection.

MMh, easy to do... You can simply solder the chips with the
"pick-a-back"-method so that the chips are one on top of the other.
Only pin 17 of the 68010 and of the 68000, too, mustn't be soldered
: These are the _HLT_-Pins. And now you need simply a switch
for switching the 68010 or the 68000-pin to the motherboard...
So only one of them is in function, the other is reciving the
_HLT_-signal

Luckily, C= managed to solder in the processors the right way round. This is
definetely *not* the case with the pullup resistor packs on the A2630. 
Maybe they should have been socketed :-( The cost of turning them round re-

I am an addicted Amiga user here in Ireland. The Amiga I have is the A500 and
was kindly lent to me by a friend of mine who has gone away for the summer.
However, as my friend will be coming back soon and will be wanting his
Amiga back - the only way I can see myself not suffering from severe
withdrawal syptoms is to buy my own Amiga!

I want to be able to program on my Amiga-to-be and the only way I can see
myself doing this efficiently is with a hard-disk. What I want to know is, is
the Amiga 500 and the A590 20MB hard-disk a good combination or could I do
better? My mother is going over to the US next week - so I would like to take
advantage of the cheaper hardware prices that the US has.

I can get an Amiga 500 quite reasonable second-hand here in Ireland so I 
would like to know what the US prices are for hard-disks (and also maybe an
add-on-driver) - hopefully not more than $350 (approx 200 Irish pounds).
I know very little as regards the multitude of hardware available for the
Amiga and I am just wondering would I be holding myself with an A500 with
respect to hard-disks, or should I think of a more powerful Amiga - again
money is the only thing holding me back!

I would very much appreciate any advise anyone can give - Thanks,

I'm looking for the simplest way to hook up an analogue to digital
converter to the Amiga, for audio digitizing experiments.

Memory-mapping the ADC using the expansion bus looks complex because
of the auto-config support.  Or can I bypass this and stick a latch in
the address space somewhere simply?

The simplest option seems to be to use the parallel port.  The RKM
describes the software interface, and the hardware manual labels the
pins, but I haven't found any description of the handshake sequence.
Can anyone tell me the handshaking required for READING data from the
parallel port?

It's no rumor.  I purchased this bundle directly from Moonlighter several
months ago, and it's been working flawlessly on both my machine (GVP

$375, not $475.

I recently received the flyer for the 'Touchdown' tape drive offer from

was still chuckling to myself as I threw it away.

Since the '040 has to emulate some '882 instructions with software, perhaps the
'040/'882 combo is legit... perhaps the '040 won't have to soft-emulate any
instructions, it can pass them on to the '882.  Not as fast as having those
instructions on-chip, but faster than software.

the RAM32 can hold 8Megs of memory.

Why to get a VXL over a MMR CPU max 50Mhz FPU max 60Mhz.  The 32bit
ram will auto-config so it is DMA'able no harddrive(DMA) slow down
accessing 32bit RAM.  The 32bit ram supports 68030 BURST access.
Also sence the the 32bit ram auto-configs the WHOLE OS is placed
in 32bit ram from startup.

>onto? (i.e. an exp. board, CPU, etc).  Also what is its ceiling.
