I'm thinking of heading over to frys this weekend to pick up an LCD TV for use with a few classic computers and maybe classic gaming consoles. I'd like something that will have good image quality for use with things like Amigas and c64s. I'd like to avoid things like submarining mouse pointers, ghosting around letters (ringing?) and aspect ratio problems. A VGA port would be nice also. Bonus for being able to use the NTSC frequencies when the signal is coming from the VGA port so I can attach the amiga right to that. Obviously, I'd want a composite and svga input also. Even coax would be useful in case I pick up a 2600 or colecovision. Can anyone suggest a make and model that has all of this? brian

PDP-11 card set M-215

by wdonzelli＠gmail.com

I have a set of cards installed in a PDP-11/24 I am readying for sale, and I can not ID them. They are a pair of quad heights, linked by a ribbon cable, and the etch says M-215 INTERFACE. The logo is a B with eight arrows coming out, sort of forming a square. The logo looks familiar, but I just can not place it. There is a place for an external cable or two to connect. Any ideas? M215? There is also a mystery hex height CDC card in this thing - possibly the mythical Unibus Cyberchannel card. -- Will

Eric is correct, at least in my experience on the XMP-48 that was at PSC. VAX/VMS front ends were used to edit programs and submit them to to the Cray (running COS), and some time later the results would return. I sent code to someone else on a different front end, and as I understand, all he had to do was mod the script to submit the jobs for the local toolset. No changes to the code. KJ

SuperPet add on board

by rborsuk＠colourfull.com

Hi All, I was chasing some links this morning when I got wondering if anyone reverse engineered / upgraded the superpet add on board for the 8032 PET? 8032 PET's are pretty common and it would be pretty cool to get an upgraded add on board to turn it into a Superpet. Maybe with an SD slot on it or a networking port. Rob Rob Borsuk email: rborsuk at colourfull.com Colourfull Creations Web: http://www.colourfull.com

Well if I do eventually donate my mainframe it will be on the proviso that it remains my property until I die so that they cannot do that even if the machine is in storage in the hanger in Dorset. If I didn't mind it being messed with I could sell it for a lot of money myself. Spare parts I donate with the machine are a slightly different matter, provided they are swapping for things to be used on my machine. I am still amazed at the price of punched cards on eBay. I've got enough we make notes on them and that horrifies some people, but I bought 110,000 of the for 11 pounds back in the late '70s, though I did break the suspension on my father's Daimler transporting them.

p112 thoughts

by dgriffi＠cs.csubak.edu

After getting another inquiry about the P112 kits, I started wondering how many people would be interested in putting down money for a pre-order before I actually order the parts and boards. That's partially the way it ran for the run of 100 I did a few years ago. More recently, I made an expensive mess running a prepaid group order for FP-6120 toggle switches, so I'm bit shy about taking preorders again. If anyone out there has deep pockets to help me finance something like this, I'd be glad to get the help. I could use the business too. Unless and until I get a new job, this is probably the only way I can get P112 kits made. See me at 661.org if you have any questions. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing?

Anyone off to VCF-UK?

by classiccmp＠philpem.me.uk

Hi guys, Just out of curiosity, is anyone planning to attend the UK Vintage Computer Festival this year? The one that's running on the 19th and 20th of June at Bletchley Park? I'm toying with the idea of booking some time off work and going down on the train for either the Saturday or the Sunday; I'd rather like to see the talks by Sophie Wilson and Tony Sale, although it'd be nice to meet up with a few of the UK-based classiccmp'ers as well. The mailing list is fine, but it'd be nice to put names to faces :) I also figure the "VCF Flea Market" might be a good way to get my sticky paws on some 8-inch floppy drives, discs and possibly an MFM hard drive and controller pair or two. I still don't have a working 8in drive to test the DiscFerret with... Speaking of which, I could be persuaded to bring the current "circuit test" prototype down with me, though booking a table will probably be a real pig at this late stage, and I'm willing to wager it's probably going to be too expensive for my budget anyway (I'm saving my last ?150 to get a run of prototype PCBs made!)... Cheers, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/
