>Of all the drives I could find in the store, only 3 worked. but now >Mr.StoreGuy has a pile of "Tested-BAD" drives! (Well good for steppermotors >anyway) Ah, but the store owner now had one more thing in the deal, an education, don't let anybody test your stuff at a fixed price. Its the kind of mistake easy for a basically honest person to make. OTOH Apple II drives are pretty hard to break, --- I still have a broken one, can I fix it myself? the only thing I know is when I put a diskette in and try to read it it goes rattttatt and gets an error... :^( ---- how did you test them? ----- I connected them to my apple II and put in a known good diskette, swapping the diskette to the other drive to verify it was still known good... :^) ----- Could it have just been incompatibility? Thats the second risk, customer tests your stuff pronounces it bad, but later on it turns out they (generic they, not you) didn't know beans and the stuff is just fine (which of course you find out after customer B buys it for parts and retests later).

I don't know where you got this misinformation from, but Power Macs do support 800K floppies (apart from recent models which don't have a floppy drive and perhaps the G3 models). Every Mac previous to the Power Macs also supports 800K floppies (apart from the very earliest ones which only had 400K drives). See the "Power Macintosh 7600 Series: Technical Specifications" at http://til.info.apple.com/techinfo.nsf/artnum/n19545 Other Technical Specifications documents on the TIL site for other Power Mac series computers also contain this text: * Internal Apple SuperDrive floppy disk drive -- Accepts high-density 1.4MB disks and 800K disks -- Reads, writes, and formats Macintosh, Windows, MS-DOS, OS/2, and ProDOS disks Also see http://til.info.apple.com/techinfo.nsf/artnum/n19545 This has a brief explanation on why access to 800K floppies is slower under newer Mac models. -- Mark

If your OS > isn't interrupt driven, you don't need these. hmmm.... then it is possible that some cards are missing because there are intermediate empty slots; here's the back cage configuration: Slot # card description ----------------------- 25 -empty- 24 BACI 12966A 23 Jumper 22 Jumper 21 BACI 12966A 20 BACI 12966A 17 BACI 12966A (note: no slots are labeled 19 or 18) 16 Jumper 15 Jumper 14 -empty- 13 -empty- 12 DISK INTFC 12821A (HPIB; why a second one?) 11 DISK INTFC 12821A (HPIB) 10 TIMEBASE GEN I was able to open the front panel (thanks, Eric) and found the following there: Slot # card description ----------------------- DCPC D.C.P.C. | Ribbon connector from front fingerpad to bckpln 111 MEMORY PROTECT 22-7931 112 MEM 22-2127 113 -empty- 114 -empty- . . . . 120 -empty- 121 256KW HSM 12749M | these three cards have their left front fingerpads 122 256KW HSM 12749M | joined by ribbon cable.

If this matches your situation, drop me an email > and I'll look it up for you. I did not move the cards around, but again, maybe some cards are missing. I don't know what OS the system was running. I guess that the first thing that I have to do now that I tested the power supply and verified that the machine (seems to) turn on, is to build a serial console cable for this. I have several cables that will fit the BACI boards, but the connectors at the other end have been cut off. Does anybody have the pin out for the finger pads in the front of the BACI boards? -- Carlos Murillo-Sanchez email: cem14(a)cornell.edu 428 Phillips Hall, Electrical Engineering Department Cornell University, Ithaca, NY 14853

TI Professional Computer

by rigdonj＠intellistar.net

I picked up one of these today but some of the files on the hard drive are messed up. Can someone send me the Command.Com file for MS-DOS 2.11A? Also how do you get one of these to boot from the floppy drive and not the hard drive? Joe

*Way* OT: Sale of Goods Act

by Glenatacme＠aol.com

Hey Tony: > ARD : 'If any part is missing or damaged then I intend to return it here > and now for a cash refund under the terms of the Sale of Goods Act. This is really off-topic for the list so feel free to reply directly to my e-mail address -- I'd like to know your (and the group's) opinion: What is this "Sale of Goods Act?" (I knew the UK paradise had to come with a catch) Here in Florida a merchant doesn't have to give a refund, period. Please advise. Glen 0/0

I just placed a low-hours H19 terminal, equipped with a Northwest Digital Systems "Graphics Plus" option (Tek 4010 emulation), up on Haggle (I refuse to deal with E-pay!) for those who may be interested in such.

Finds

by jbmcb＠hotmail.com

Went to Chicago to visit relatives over the weekend but couldn't find any decent used computer stores. Maybe they are in the suburbs? Highlight of the trip was I stayed in a hotel, room 1337. ph33r hax0rs! Went to the local salvation army and picked up an Atari 850 peripherial expansion box, a Disney Sound Sources paralell port sound box (Funny) a few assorted cables, and most importantly, a book on various expansion bussees circa 1983. Covers S-100, Tandy, Multibus, TI/99, Apple II./III. Interesting stuff, and cool pictures of wacky niche machines (The Heathkit LSI-11 Computer, The KIM-1) Happy Hunting!
