Greetings ... I am still working on my TCP/IP for DOS. It has been over five years now. :-) For the past few days I've been testing an FTP server. The server is running on a PCjr with DOS 3.3, a SCSI Zip 100 for mass storage, and a Western Digital WD8003 Ethernet card. (The Zip is attached using a parallel-to-SCSI adapter and the WD8003 is on an ISA bus adapter.) The FTP server supports most of the standard commands. If you use anonymous FTP you will be limited to a 'sandbox' on the Zip drive that is 30MB in size. You can leave files in the '/incoming' directory - everything else is read only Six people can be connected at a time, but the machine can only transfer data at about 25KB/second so if multiple people start data transfers it will get painful really fast. That's just a limitation of the machine - a faster machine would do a much better job. (A TCP/IP socket with this machine can transfer at data rates up to 100KB/sec. The Zip drive can so sequential reads at around 50KB/sec. So I figure that 25KB/sec isn't that unreasonable.) If you'd like to try out some of your favorite FTP clients I'd appreciate the extra testing. You can get to it at 96.42.228.74 on port 2021. Browser users can use ftp://96.42.228.74:2021/ for a URL. If you are curious as to how the machine is performing or who is on the machine try the 'SITE STATS' or 'SITE WHO' commands. Chuck(G) has already broken it once by using DOS reserved names that I forgot to filter. That bug, and an obscure timing window related to passive data connections have been fixed. If I can keep it running for another day or two with reasonable traffic I'll consider it a success. Thanks! Mike

I have the 8 meg disk system: http://www.xs4all.nl/~fjkraan/comp/trs80m2/8megDisk.html, but still haven't found time and space to properly test it. Replaced some blown capacitors, but that is all sofar. The authorative source for most things TRS-80 is Frank Durda's site: http://nemesis.lonestar.org/computers/tandy/hardware/storage/mfm.html. The original 8 Meg controller emulated the WD1000 chipset even before it was on the market. So it should look like something familiar :-). Fred Jan

HP Portable+ disks

by ard＠p850ug1.demon.co.uk

Although the HP Portable+ Technical Reference doesn't contain anything on the physical disk formats, there's a table in the usner manual for the FORMAT comamnd (I've changed the headings a bit, but the data is the same) : Specifier #sides Secotr size Capacity Files in root dir /w 1 256 264192 128 /x 2 256 618496 304 /y 2 512 700416 176 /z 2 1024 780288 96 none 2 512 700416 176 The default seems to be the same as other HP MS-DOS double-sided disks. I wonder if Chuck (I think) got a disk formatted wit hthe /z option from a Portable+ and sassumed it was the defualt? -tony

The case & PS are in use for one of my Cromemco external hard disk drives, but I do also still have the controller card; PS connector, LEDs and the DIP sw were removed, but otherwise it looks complete. mike

S: SNA.PS/Mac (Classic) and/or AppleTalk PTF for OS/400

by poc＠pocnet.net

Hello, I recently saved an old AS/400 box from being dumped to learn a bit of the system and OS. Since I'm also a long standing Mac user, I'd like to experiment with sna.ps on old boxes of mine. I have a IIfx with a Apple Token Ring 4.16 board and also the AS/400 has Token Ring up and running. The ring itself works ok for TCP/IP and IPX with some devices attached. I'm searching for the original Apple sna.ps software in any version for getting the two worlds together. Anyone has it? Unfortunately, the code has been sold multiple times to different companies. Copyright is now held by MochaSoft. There has been no response to my inquiry there. So I think thy just don't care for old stuff. I'm also searching for the AppleTalk PTF for OS/400 V4R4M0 to enable the AS/400 speaking AppleTalk natively. Anyone can provide a SAVF of that? IBM doesn't support V4 in no way anymore. Thanks for any hints or help! :wq! PoC

seeking LT-1 floppy

by dgriffi＠cs.csubak.edu

Is there someone out there with an LT-1 floppy disk or two they'd be willing to sell or trade? -- 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? A: Top-posting. Q: What is the most annoying thing in e-mail?

Ahhh, it does have that early Mac look to it. What did Omninet use for media? There is no other connector beside the 9-pin. Is it the three little pins?

OT: Scrapper question

by cclist＠sydex.com

Does anyone know if tantalum is recovered from electronic waste? No particular reason for asking, other than pure curiosity. Thanks, Chuck

Apple/Corvus Whatsit

by silent700＠gmail.com

While sorting through my voluminous Apple // hoard today I uncovered this device: http://silent700.blogspot.com/2010/12/what-is-it.html Anyone have any idea what it is? There in only the ribbon cable with 9pin male connector on it and the cutout which has 8 DIP switches and a 3-pin connector. I am somewhat familiar with the Corvus hard drive and networking systems for the Apple // line but I have never seen this. I also uncovered a boxed (board, manual, sw inside) Apple Turnover kit. The floppy is (c) 1985 F. Cisin. Is that our own Fred Cisin on this list? I have at least a couple dozen (so far) mystery Apple // cards in this box....I *know* if I approach the search correctly, one will be a Swyft ;) -- jht
