Hello, I have a PET 2001 (original with 6550, 6540) which boots to a garbage screen, but rather than it being random it's actually very similar each time with just some characters changing. I have tried a ROM/RAM replacement board, as well as Vossi's 2001 PET TEST ROM, which I've used on...

As subject I would like to get hold of a serial CRT terminal. The older the better but would consider newer models too. Condition doesn't really matter, would prefer working but non-working is also fine. I'm up North but can travel / arrange courier :cool:

One of my PET 2001s screens has suddenly decided to go white and not boot. It was working OK, I left it running a simple test program for a while, came back to a totally solid white screen with the blank screen borders around it. Removed all the VIA/PIA and RAM and built it back up, still...

I have a PET 2001 with the fuse cap removed, it would be the same type as seen here: It takes the longer-length fuse compared to later PETs. I could of course replace the whole thing with a newer fuse holder, but it would be even nicer to know what type the original was :D Does anyone...

I might be wrong, but I am 99.9999% sure the floppies in that ad are fake... See how they all conveniently use the same size label, in the same position with the same iffy-looking white border, lacking copyright info. My jpeg-o-meter went into overdrive! A quick Google shows none of the...

Apropos of nothing... pointless trivia question alert... I was checking out my "COPYRIGHT 1977" 320008 PET just now, and it occurred to me; supposedly a number were sold in '77, many PETs have the '77 PCB, some have a selection of '77 components, but most also have later (factory installed)...

After help from AndyG on here, my PET 2001 monitor is fixed, so I've now turned attention to a spare board I have. A clean looking 320008 (dated 1977) is showing this funky prompt. You can type but nothing much happens other than duplicating what you type across the screen. Cassette motor...

Hi, I have at least a couple of issues with this PET, both should be apparent from the attached photo. Firstly, the screen is very bright. The picture is with brightness on the lowest setting(!), turning it up just results in an even brighter image. The board seems to be partially booting as...

I have a PET with no drive (boo!), I do have a cream Vic 20 style one, but it's not the same is it? I would like to purchase a black C2N therefore. Doesn't matter if the bracket isn't included. I can purchase, or trade (don't have much, some 8-Bit, some ISA boards, but ask if you need...

How are the bezels attached on PET monitors? Just glue? I'd like to remove mine without having to go through the CRT etc, if at all possible!

I have some C2N spares, including salvaged PCB, and was wondering if I could install this in a non-Commodore tape recorder? Assuming the motor used the same voltage etc?

I would like to buy this model, working or not, just as long as it's physically complete on the outside : I'm in England but would happily buy from anywhere in the world if the shipping is reasonable enough :cool:

Just as a sort of not-very-interesting update... I discovered they were also sold in Brazil under the brand CCE (who are still going) Following ad is from 1973:

What is the current best program(s) for testing a system? I've got Topbench, Speedsys, the Vogons benchmark tools, but these seem more geared towards speed rather than stability. Is there a program which will push the CPU and RAM to it's limits, revealing an unstable system through demanding...
