There was a GPIB version of the drive used in the 405x that I have. The service manual goes into more detail than the service manual for the main unit. I also have a couple of the bare drives and had intended to hook them up to the same sort of interface that I've been using to deal with other cassette media.

Commodore PET

Date: Fri, 09 Nov 2007 10:22:41 +0100 From: Jos Dreesen / Marian Capel <jos.mar at bluewin.ch> Subject: Re: Commodore PET <snip> >To think I left a chicklet keyboard pet in a dumpster, just a few years >ago. "Too much stuff, it's just a PET, I can always get another.." >Jos ------------ I probably put it there ;-) Just one of many things I dumpstered before I saw the light; the North Star and CDC terminal I tossed because I only wanted the desks, the Cromemco Z-2 because I only wanted the PS, the calcs I wanted the Nixies and core out of, the Selectric and Diablo printers, Burroughs L, F and E stuff because I figured no one would ever 'collect' one, etc. etc. Regrets, I've had a few... Fortunately I kept my original PET 'cause I was (and still am) using it occasionally. m

Commodore PET

by dm561＠torfree.net

Date: Fri, 9 Nov 2007 20:24:38 +1300 From: Ethan Dicks <ethan.dicks at usap.gov> <snip> If someone tried to hack DRAMs in place on a static board, I'll bet that's a mess. I have a 2001-16N board with factory perforations on the high 16K RAM pads that I'd like to eventually reburbish to a full 32K. If you really are interested in finding someone who is willing/able to make that one live once again, I am entirely willing to give it a go. I don't have a shell here, but I already have a 3032 board on the way here >from Sweden, so I was planning on trying to build a keyboard adapter of some kind and an XOR-based composite-out adapter with a closed-circuit TV monitor to get it all working. Doing the same for an old PET wouldn't be that much of a stretch (I was planning on using a C2N232 adapter for mass storage, eliminating the need to send down a real floppy drive). -ethan --------Reply: I was going to do the same thing, sort of a PET in an AppleII-type case, but it'll never happen so you're welcome to it. I've also got a keyboard for it (the later version) and video's a no-brainer. I also have a case (no monitor) but I think I'll keep that in case I _do_ decide to do this one day with another less needy mobo. Mind you, the plug-in chips are missing, so by the time you've hacked in a 32K RAM chip and EPROM there wouldn't be much left of the original PET... We'll talk off-list. m

Date: Thu, 8 Nov 2007 22:36:27 -0800 (PST) From: Cameron Kaiser <spectre at floodgap.com> Subject: Re: Commodore PET >>> The last PET 2001 with the chiclet keyboard I bought cost me $35. >>> Clearly, there are bargains to be had. $150 is a fair price though. > >> Shhhh! >> I wanna find another Cameron that'll give me $900! >In all seriousness, I think it was worth it and I'm happy to have it. >Wouldn't drop that kind of coin on just anything. More power to ya, I say. The value of this kind of thing is purely subjective, depending solely on what it (and $900) are worth to *you*, and I too feel that there's something very special about that model and the community that grew up around it (especially here in Toronto, Commodore's birthplace and home of Jim Butterfield, TPUG, The Transactor, Batteries Included etc), as opposed to AppleIIs & R-S M1s. Remarkable that TPUG (Toronto PET Users' Group) is still around, and even with some of the original members (although scaled down somewhat from its glory days). Of course it was my 'first' and I have many warm memories and pictures of me and family playing with it, not to mention all the doodads & mods I made for it, so I'm somewhat biased. Then again, from the point of view of the 'collectors' on this list, it should be worth $0... m

the Alpha Micro Phun Machine

by spectre＠floodgap.com

One line of systems I see very little about on the web or in vintage computing circles are the Alpha Microsystems units (not! DEC! Alpha!~). Now that I have my own Alpha Micro Eagle 300, I've compiled together most of my notes on various models, a primer to AMOS, some software and a link library and put the E300 into the server rack so that a real AMOS/AlphaTCP system can serve it itself. Hopefully this will be useful to other people who have been curious about Alpha Micro boxes. http://ampm.floodgap.com/ -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- I'd rather be a lightning rod than a seismograph. -- Ken Kesey -------------

Is it worth $150? Just curious, since I saw one today with that price tag on it. Looked to be complete, at least. Doc

After about a year it continually needed opening up and the chips reseating, got so frustrated with this that we replaced ALL the Ic sockets with "turned pin" types and never had anymore problems with that machine ever again.
