First of all.
Anybody know where the pinout diagram is?
I've looked in the usual places and nothing.
Comments
Anybody know what board this is?
Schematic for this would show what pinout of Stamp 1 DIP is.
Here is article about board.

The ad has Parallax PIC programmer, compiler and 8051 like language info in it.Fascinating!
That was Parallax's claim from day one.One click programming.Interesting.
Everything you need to get the pinout is probably in here:
https://www.parallax.com/sites/default/files/downloads/BS1-IC-Schematic-Rev-D.pdf
That is technically a SIPP. Also it's a module.
Here's the link for the version of Stamp 1 for pinout we're looking for.
https://www.parallax.com/product/pbasic1_p
If you look at it tho, you can see the wiring INSIDE the sip, which shows how they interfaced to the interpreter, thus the pinout, they even have the detail of the interpreter chip inside the sip, the pins are labeled for the pic16c56.
Parallax documentation says SSOP stamp 1 and DIP have different pinout.
They say to to see PIC 16c56 datasheet.
I am a little leary of connecting up like a PIC.
'Note: The 18-pin DIP package of this chip has a different pinout than the 20-pin SSOP package; pay close attention to the package shown in schematics and refer to Microchip datasheet for PIC16C56A for pinout information.'
It was right on the sell page.
Still not gung ho about connecting it like a PIC!
Here's the datasheet.
http://ww1.microchip.com/downloads/en/DeviceDoc/30453E.pdf
I guess they are using Port B for the 8 I/O pins.
Then Port A for serial communication.
Then OSC pins for 4 mhz crystal.Then VDD and VSS.
Still not going to go for it and just start hooking it up.
Well, look at that, I missed that obvious difference..
OOPS! Looks like you got it!
'Well, look at that, I missed that obvious difference..
OOPS! Looks like you got it!'
It is a tough one!
Well. On monday parallax should come up with a pinout diagram.
How do they expect me to buy one if there is no way to connect it?
Most people use the pre-built modules and the interpreter chips are for people that want to incorporate the Stamp into their product.
I personally wouldn't risk releasing the magic smoke until I was experienced in using the Stamp.
'the interpreter chips are for people that want to incorporate the Stamp into their product.'
How about people that want to use a breadboard?
'I personally wouldn't risk releasing the magic smoke'
The odds will go way down once we get the pinout.
That info must be the hardest to find in Stampdom.
It was more available in the Nuts & Volts article era.
When the Stamp 1 was the only game in town.
Note the ad.Parallax total Stamp products? One.
Basic Stamp 1.Stamp DIP on a proto board.
Here is Stamp 2 DIP schematic.
https://www.parallax.com/sites/default/files/downloads/27291-BS2OEM-Schematic-Rev-2.pdf
From this you can pretty much figure out how to connect Stamp 1 DIP.
Download the PIC16C56A datasheet as referenced on the Stamp1 Interpreter chip page.
On page two of that datasheet, in the Pin Diagrams figure, both the 18-pin DIP and 20-pin SSOP parts are shown.
The only difference between the DIP and SSOP parts is that the SSOP part has two less pins; one for VSS and one for VDD. The organization and names of the remaining 18 pins are the same.
My bad.I did not update post after getting ahold of Support at Parallax.
They confirmed no handy pinout guide hanging around from 90's.
Using the datasheet is as good as it gets.
Support said use that to connect up VDD and VSS.
The pinout for Stamp 1 module can help you guess where the rest of the connections are.
My guess is Port B 8 pins are Stamp 0-7 pins.
I would say your assumption that the "port B" pins are Stamp 0-7 pins is correct.
Comparing the PIC16C56a datasheet pin-out and the BS1-IC Module Schematic makes this assumption very clear.
***Oh, and I misspoke in my previous email...the 18-pin DIP has the two fewer pins (Vss, Vdd), not the SSOP. Apologies for the error.
That's okay.
Thank you for your interest.
We came to our senses about this.
There is not much need to breadboard a DIP version.
We will just jumper over from Stamp 1 Project board.
This link might be what you are looking for.

Thank you Genetix
Okay.Saved all documents.
Here is the schematic and the manual.
Now this to to build a module that you stick in the breadboard.
But it is the right module because it uses 18 pin Stamp 1 DIP in an IC socket on board.
The BSI modules that are still available at Parallax are surface mount 20 pin PIC's.
They are CSI 93LC56P's.
Will also pickup up some Microchip 56kb EEPROM's for backup.
That's the progress report.
Just remembered to put the EEPROMS on parts order.Done.
Have a better idea.
Better to breadboard the Stamp SX DIP than Stamp 1 or 2.
For a bunch 'o reasons.
Will do that instead.
EEPROM for Stamp 1 DIP version.
The one in schematic for surface mount Stamp 1 is a Microchip 93LC56B. 256 kb.
Will report on how it works with DIP Stamp 1.
Stamp 2SX and Stamp 2 DIP's have EEPROMs on bottom of page at Parallax store.
Stamp 1 page the EEPROM is MIA.They are probably out of them.

They are readily available at your favorite electronics parts house.
Came up with a now project.
Breadboard the Stamp 1 SIPP we have already.
At first glance it looks like all we need is power and serial connection.
Will post progress.
We ended up with a new Stamp 1 SIPP module.

Plan is to breadboard that.
Will test it first on Super Carrier board we unearthed here.
DB9 Female Serial Port Breakout Board.Second one from top.

Then it just need power and should be all said.
Don't think it needs an RS232 IC.
Forgot all about the Stamp 1 adapter.
The Stamp Project board works with a regular serial connector on it.
I will stick it out with the serial breakout board.
Yes we do have a Asus motherboard w/serial and parallel ports system running XP.
It's for the old software and boards.
Have a proprietary PIC programmer that is parallel port and that is about it.
Parallax was just parallel port at the very beginning.
Then they switched over to serial port.
I forgot which board the Stamp 1 adapter connects to with the 3pin header.
I don't like using it because it's rickety standing straight up the way they have it.
Same thing with the Stamp 1 SIPP module.
