I have a quantity of ARC(E) Ltd. boards, from a complex calculator, or small computer. They are in CHesham, Bucks, UK, collection only. A small donation would be welcome, but I'm not that bothered. There are a couple of largish boxes of the things. They go for scrap in acouple of weeks, if not claimed. Jim. Please see our website: www.g1jbg.co.uk

I have been daring and opened up the drive to clean it off. if this is the problem it can of coarse trash the drive if it gets off the stop post. Cleaning is on easy and takes some time. The next challenge is getting something to replace it with out taking the drive apart. (head alignment.) On some Quantumn 8" dives I spilt some tubing and rapped it around the post with contact glue. So far they still work Jerry Jerry Wright JLC inc.

Looking for old VMS and Ultrix releases

by sethm＠loomcom.com

Folks, I'm trying to hunt down old VAX/VMS releases (earlier than 5.4) and old Ultrix and ULTRIX-32 releases (earlier than 4.2, both for VAX and for RISC). Tape images or CD-ROM images (where appropriate) would be quite welcome, I don't need any original media. If you have any of this stuff lurking around, please do let me know. Thanks very much! -Seth

Kinda OT: LASCRs?

by mcguire＠neurotica.com

Hey folks. As a kid in the 1970s with access to only Radio Shack for parts and educational materials, I had a lot of Forrest Mims' books. I've dug up a lot of the ones learned from (new copies via eBay; my original ones are sadly long gone) and in fits of nostalgia I've built quite a few of the old circuits I played with when I was 8 or 9. One component that I really liked was the LASCR. I had one which I used in a few different circuits back then. While I still have some of my old stuff from that era, that one LASCR is nowhere to be found...Now it seems they've disappeared from the scene entirely. Has anyone seen any lately? Is anyone making them anymore? -Dave -- Dave McGuire Cape Coral, FL

I seem to recall reading about the Apple 1 in either one of my 80 Microcomputing mags or, possibly more likely, the book On The Edge: The Spectacualr Rise and Fall Of Commodore (published last year). Personally, I think it's good to mention rival computers and/or previous models when talking about specific computers. I can see nothing wrong with what you have put and can only say that you have unintensionally rattled a KIM-1 fan. Regards, Andrew B aliensrcooluk at yahoo.co.uk

ASR-33 conversion to 220V

by jos.mar＠bluewin.ch

I want to convert a ASR33 from 110V/50Hz ( yes , 50Hz) to 220V. Is it sufficient to swap the motor and fuses ? A nice touch of this particular machine is the unused "here is" option. I wonder if a small bootloader would fit in it... Jos Dreesen

What would it take...

by lee＠geekdot.com

> to make one of these in discrete logic: > (if you don't feel like looking, it's an Apple II > IDE/Cflash controller) > Just a rough chip count. Two 8 bit buffers, two 8 bit latches and one GAL20V8 or similar. The GAL isn't essential but saves four or more packages to do the address decoding. Lee.

TCP/IP, FTP, and MSDOS?

by julesrichardsonuk＠yahoo.co.uk

Out of interest, what do I need in the way of TCP/IP software / configuration and FTP client software so that I can connect to a remote FTP server from MSDOS? I don't think I've ever set up such a config from scratch. I can live with 10Mbps speeds if required (would DOS drivers even drive a card at anything more anyway?) NIC cards I seem to have available: Netgear FA310TX (PCI) HP 88809L (ISA) 3Com Etherlink III (PCI) 3Com Etherlink III (ISA) Asix NV100AM (PCI) 'Network Everywhere' NC100 (PCI) 3Com 3C905 (PCI) The ISA boards perhaps have the drawback that they're software configurable, so I have no idea what settings they'll want to use (or which interface), or how well they'll behave in the new-ish system I need to put a card in. The PCI boards on the other hand are newer so maybe DOS drivers don't even exist for them... (Etherlink III's were always reliable I seem to recall, but I never did like the idea of them being software configurable; it was much nicer to have jumpers on a card and *know* what it was configured as!) cheers Jules -- there's a carp in the tub there's a carp in the tub so nobody's taken a bath
