ISA Card? There were several. *very* expensive - maybe $500 or so for maybe 12-14 TTL chips on a short 8-bit ISA card. I've got one - been thinking (maybe not very seriously) of putting everything into an ASIC or FPGA as a do-it-yourself project. Realistically, how many tapes are there out there that need to be read? Found a Qualcom open style deck not long ago - it's a SCSI, and a lot lighter and easier to haul around than those F-880 Cipher pigs. Which are taking up space ''just in case''.

Which are taking up space ''just in case''. Heh. You've never moved a Fuji M2444AC, have you. The Cipher F-880 is tiny. The "right" way to do 9-track these days is the HP 88780. SCSI, caching, fast, quiet, self-threading, and as far as I'm aware, still being produced. -Dave McGuire

PC-ISA Pertec-Interface 9-Track Magtape Drive Controller Sought f or Rent/Lease

by dhquebbeman＠theestopinalgroup.com

Ok, Has anyone got a PC- (actually any bus will do except MCA) compatible controller card for Pertec-interface tape drives like the Cipher F880 that they would rent or lease to me for a while? Electrovalue has one for $250, but if I could spare that much I could get the Prime running and wouldn't need the controller. Of course, loans are acceptable as well. I'd need docs on how to address it in code, or some code that will talk to it, etc. Tia, -doug quebbeman

CD Eating Fungus?

Has anyone tried playing them backwards? I had thought it was common knowledge, the reflective layer in many CDs is sputtered aluminum. When exposed to oxygen (as can happen when oxygen migrates through the plastic or the plastic is cracked) the Aluminum oxidizes and turns black. It does look a bit like a fungus but only because it tends to follow the grain pattern in the deposited aluminum. Aluminum-oxide is black and quite hard actually. I've seen several examples of this in "real life" and while I have never seen the process to actually _remove_ Aluminum from the disk it is conceivable that the Al02 would form a different crystal matrix and thus change its orientation relative to the original sputtering. That could leave 'gaps' where the original reflective layer was. So folks to don't understand chemistry invent the 'fungus' idea and off it goes into urban legend-dom. --Chuck

Interesting British computer needs good retirement home

by vcf＠siconic.com

Roy Jenkins e-mailed me looking for a new home for his old "LSI System-M-Three" computer. The message below describes this machine. He lives in North Gloucestershire in the Village of Weston-sub-Edge near the small town of Chipping Campden. If interested, please reply directly to Roy.

Wave of the Future (Spam)

Another difference between junk snail mail and spam is that the junk mailers actually have to pay for each item they send out. Not true with the email spammers. The only thing that holds them back is the lack of addresses and those are readily available from companies on eBay and such. Anything that is free and readily accessible will always be exploited by some, regardless of how it affects others. Jeff

They didn't just change the name, they changed the format as well. I'd been a big ARC user, having switched from SQ/USQ/LU/LDIR etc. PKARC and PKXARC were so much faster, I switched immediately. You know the rest of the story. I kept DOS (for sure, and maybe CP/M) executables of them so if anyone needs them, let me know. However, they don't appear to run properly under CMD.EXE (maybe CONFIG.NT needs a tweak). Regards, -doug q

New finds in Houston

by jrkeys＠concentric.net

I just got back from 18 days down in Houston and in-between working (and the flooding) I was able to hit a few thrifts there. I got the following: 1. A handheld called Compact by Ultratec with a acoustic modem in the top cover. It's 8 1/2 x 3 1/2 and 1 1/8 inch tall. It has no other markings on it. 2. Six new in the box Vic20 game cartridges 3. R.O.B. by Nintendo robot 4. Something called a Xscribe that looks like a over grown C64. 5. A alphamicro 1000A model AM1000-47 6. Radio Shack TRS-80 TP-10 thermal printer 7. Several new in the box TI99 cartridges 8. And about 50+ more items that do not meet the 10 year rule. It was a good trip just wish the weather had been better.
