I''ve got a PET2001 with the 8050 duel drive with the printer. My question is ,is the printer worth much? Haven''t seen any on line anywhere.

Got a bit of a story about the 2001-8. I got the opportunity to work in a lab that had an aging Friden EC-132 (first RPN calculator was EC-130). At that time I saw an advertisement in the back pages of Scientific American for this Commodor computer. I convinced my superior that with a bit of programming I could make the Pet replace the Friden. I did mention that I had only taken one introductory course in Fortran at college but Basic was similar to Fortran, so I was told. Also mentioned that since a card used up about 100 bytes we should go for the 8k version. Anyway Pet was purchased and I wrote the program which provided a bit larger stack but no better precision. I also added several other features but in all a success, my first at programming. Needless to say I ended up writing a lot more programs and left Chemistry far back in the rear view mirror.

My first computer, the 8K version with the insane chicklet keyboard. When I finally brought it home, I couldn''t plug it in the wall ''cause my father''s house had groundless duplexes. I had to go to a neighbour and get a "modern" duplex to replace the one in my bedroom. Then I sat at that keyboard for 24 hours straight! No, I did not become a programmer. But I still stay up all night, hell, I''m typing this at 01:00 in the morning...

Isin÷÷ri,
If these cassettes are still available and you are still around, then I''m interested.
Please email me random6000$at$mac.com

Can''t believe I paid some ú700 for this in 1978. I still own the later 32KB full keyboard version stored in my house loft.

When I got this 8KB PET home, was very excited to have a go at programming (BASIC). Worked great for some continuous 12+ hours use then the screen gradually faded slowly to all white (or was it green?) to almost unreadable text. Being an electronics engineer, I soon traced the fault to an Integrated Circuit (SN 74F02 was the faulty when hot chip) on the logic board, I replaced the IC and all was well again.

Still have the very bulky dual 5.25inch IEEE floppy drive - 160KB per disk side, speech synthesiser, IEEE dot matrix printer and third party sound box (Music 500) which was quite hard to programme in reality to get any sensible pleasing musical sound out. I dread to think what all this must have cost me in those days.

Hi, I recently found some old C-cassettes. BUT I have left my Commodore PET to a previous workplace about twenty years ago. Anybody interested?

Just bought a PET 2001. It is missing one of the shift-keys and i still have to find out whether it works. This was my first computer i used, and took the first babysteps in programming on. The PET i bought even has a "ram adapter" (i guess it is extra RAM)... I love how the hood pops open...

Wow! This was the first computer I ever used, at the age of 7. My grandfather (Commodore Canada CEO Ed Kelllow) brought it home for us in 1980. I brought it to school for show and tell. You could set a radio next to it and hear the game you played coming through the static. The wrong sort of 'wireless' technology. Wow. Got me started programming - a pursuit which now feeds my family. :D

I doubt that little programm turning the motor on and off quickly. The motor would just run slowly.
However if you'd insert somekind of delay so the tape would have to actually accelerate and stop you could slowly damage the tape-drive.

There might also be a capacitor in parallel with the motor, that could cause rather high currents when the voltage is turned on. That might cause problems. However none serious enought to cause a computer to burn. The worst which could happen is a burnt transistor or a defective motor. Both should be standard parts.

We had a 2001-8N in our computer science lab in high school. No one wanted to use it because of the keyboard and the somewhat peculiar graphic keys. Also, it only had a datasette - no disk drives. I was hungry for computer time and didn't want to compete for minutes on the TRS-80, so I learned how this machine worked (including how to type on one - believe it or not!). That started me down the Commodore path - a fun journey, which continued with the VIC-20 (the first computer I actually owned), and later a fine C-64 system with 1701 monitor, 1541s, etc. All because of that boxy little 2001 in the corner at school.

We had a couple of these in our 'computer room' at my prep school, Spratton Hall, Northants, UK. I remember writing some kind of platform game for it (I can't remember what I called it) which had some success with other pupils! The character in the game was an inverse double-quote! I also wrote a horse-racing game for it. If anyone out there has a copy of these games I'd be very interested to talk to you!!
cheers Richard

The PET 2001 is the computer upon which I learned BASIC in 1977 at the tender age of 13. The main library in downtown Columbus had 2 of the 4K models in little kiosks. One day I walked up behind some guy who was programming the 2001 and I was instantly enchanted - I'd never seen a real computer before. I stood transfixed staring at the wonderful output of his program (stars or something). Eventually he noticed me and invited me over to explain how he was programming the computer. I owe a huge debt of gratitude to this stranger who took a moment of his time to start me out on this, my lifetime vocation.

Hi!

I just got an original PET 2001 with datasette on my desk. I wonder if there is any software available for this beauty...

Any idea if you can dump a WAV from an original tape on a cassette and feed the PET with it?

And where can I get software for it?

Greetings from sunny munich!

This was my first computer. My school had some of these back in the late 70s. The ones we had looked like the PET 2001-8N. They had 8K RAM, Alumunum toped "chicklet" keys all crammed together with no offsets, but THEY DID NOT have the tape drive on the left side. The was a metal plate where the casset should have been. I also remenber being told that if we broke one our parrents would owe the school $6000. One of the PETs in the Lab was connected to a Punch card reader of some kind. When was a six or seven year old I would have done almost anything to get more time on the PETs.

I had one of these when I was twelve or thirteen--don't remember if it was "2001" model. Had a teeny tiny keyboard with all the keys crammed together; you had to type with the eraser end of a pencil. Worst of all, the damn thing wouldn't write data to the cassette storage medium because of some defect in the memory! completely useless except I did learn BASIC programming on it.
