RE: More tapes - This time all Tektronix 405x series

[Monty McGraw via cctalk]

I was successfull at capturing all the files from a Tektronix 4051 Graphics
T1 tape last weekend.

Here is the link to a couple of photos of the process:

Capturing Tektronix 4051 Graphics T1 tape files to laptop


First I replaced the disintegrated drive belt with one from a NOS 3M DC6250
cartridge.

I used my 4051 to PC serial transfer program on my recently repaired and
upgraded 4054A.

I set the comm speed of the 4054 serial interface to the maximum 9600 baud,
but as it is 7-bit, my program changes all 32 Tektronix control characters
to "~X~" where X is the ASCII character corresponding to that control
character.

This way I don't lose any of the Tektronix 405x text formatting in the
transfer.

I was using ExtraPutty on the laptop to capture the program text strings,
then copied the statements into Notepad++ and saved each file.

I am also working on a Tektronix 4051/52/54 compatible GPIB MicroSD flash
drive that will emulate the Tektronix 4924 tape drive - for all of us with
these computers to use - since both the tapes and drives are very
problematic after all these years.

This flash drive contains an Arduino with my code - based on the GPIB
flowcharts and info in a 4051 and 4052 GPIB manual.

You will be able to use the existing 405x program statements with @Y for
the drive GPIB address - since I don't know how to write a ROMPACK for any
of the series :)

I plan to organize the different captured tapes in directories on the flash
- and that may mean using a non-4924 GPIB secondary address for that
command.  It also likely means I need to change any tape commands in each
program to use the flash drive GPIB address.

That's why I wanted to capture one of the Tektronix tapes with a menu - is
to ensure I could get those files to work on my flash drive design.

Wow, good job Marty.


Now there are three of us.  Brad Sebrink has a 4051, and also written an 
emulator.

The Tek guys in Beaverton have another, VintageTek.  I will contact one of the 
guys there, he may have a RAMPACK and MAXIPACK for you, his software speeds up 
the graphics incredibly, and give you a non-volatile EEPROM program store.  He 
has put all of the collected programs we have so far on there, mostly games.


I have to cut into my 4051, it quit a few weeks back, I think it is just a 
supply problem.  I can run a simple basic loop, but what it draws on the screen 
is garbled, on of the analog supplies is messed up screwing up the vector 
drawing, but the computer itself is running.


I did the elastiband transfer when I first got the machine, from NOS tapes to 
the one that was in the machine.  Tricky, but I got it working, and WEATHERWAR 
off of it and a few others, biorhythm, etc.

Re: More tapes - This time all Tektronix 405x series

[Randy Dawson via cctalk]

Hi Pete,


Send them to  Monty - my 4051 is crippled with no serial port.  I currently 
have no way to get data in and out of this, except via Micheal's RAMSTORE 
modules.


Monty, I also looked at emulating the tape drive, or the floppy disk over GPIB, 
that would be great, have the PC with a NI USB dongle.

I could not figure out how to make the National Instruments dongle act like a 
slave, its normally the master.

Re: More tapes - This time all Tektronix 405x series -SERIAL PORT

[Bob Rosenbloom via cctalk]

I used an GPIB to serial converter to get serial data out of my 4052. 
This allowed me to get 8 bit serial data, not just the seven the 
Tektronix serial port allowed for.
I used it to drive a paper tape punch/reader, just for fun. There are 
some on ebay. Also, an USB to GPIB converter should work.


Might help with transferring tapes.

Kurt,

I tried e-mailing you at the address in the header to let you know I never
received an e-mail from you but then I never heard back from you.  Are you
receiving me?

I searched my entire Gmail account and found no messages from you.  Please
