I have a PlayStation DTL-H1001H the grey version of the Programmers Tool. I can not confirm that is the correct unit. But, as far as I can ascertain from googling the info, is the PS1 I have is a DTL-H1001H. Also turns out they were used during Game Show demonstrations and had a very low production run vs the other color variants. Does anyone know what the going rate for this system? At the moment I am unable to take photos of the unit, but I will when I can! I was able to get my hands on this back when the PS1 was still going strong and at the time I was modding PS1’s and selling burned copies of games. My one friend said he has a coworkers PS1 he wants modded. When I finished and passed my testing, I would keep a record of the persons name and unit serial number. The serial number was very different to all the other PS1’s I’ve modded beforehand. When I took down the serial number, I wasn’t able to see the entire sticker, as a giant piece of Velcro was stuck to the bottom, covering most of the sticker. But when I got curious about the very strange and different serial number, I removed the Velcro, to be confused about seeing Programmers Tool. I didn’t know this meant, but after some time I thought if I remove the mod chip this thing is still going to play burned games. Turns out, what everyone in this forum knows, it still played the burned CD’s. This part of the story, is where I’m not proud of or am I bragging, so don’t judge me! I grabbed my PS1 and slapped that piece of Velcro on it and gave it to my friend to give back to his coworker. Several months later I asked my friend to see how everything is working out for his coworker. When I saw him the next day he told me he was happy and the PS1 works “great!” He must have received it as a gift, because he obviously didn’t know what he had to begin with! So I gave him my consumer store bought PS1 that was modded and in great working order and kept the Progammer PlayStation for myself. Fast forward 23 years later, with these units still having an interest in an era of PS4 Pro’s and XBox One X’s is crazy in my mind. But, what’s more crazy, the fact that 23 years has slipped by and no idea where it went, damn!
