I have an Apple II Workstation Card that will let my Apple IIe, using ProDOS 8, talk to ASFS. It is possible, but I have not done it yet myself.

I just missed it once on Usenet; by the time I contacted the owner it was already gone. It had version 2 and 3 with all the disks and manuals, too. For more help, try Usenet at comp.sys.apple2. That's where I learned most of what I know about networking Apple IIs. Paul R. Santa-Maria Ann Arbor, Michigan USA paulrsm(a)ameritech.net

If classic computers were cars...

Yes, I think the first upgrade was very soon after the launch. Ours all came with 4400's or 4600's. Anyway, if you still have any R5000's going spare, I can find homes for a couple.... :-) -- Pete Peter Turnbull Dept. of Computer Science University of York

Only the very first Indys; SGI very quickly (a few months) moved from R4000 to 4400 and then 4600, which are the same speed as, or slightly faster than, the R4K Indigo. But yes, I'd forgotten about the original R4000PC Indy, and that would account for the story. > Certainly the Indy was available in configurations which are a good deal > quicker than the fastest Indigo (150 MHz R4400), though there are > operations for which the Indigo's Elan graphics are quicker than the > Indy's top-of-the-line XZ graphics... That's certainly true, so I'm glad that one of mine is an XS24 and another is an Elan, although the R5K might make a difference even then, or so I hear on comp.sys.sgi. -- Pete Peter Turnbull Dept. of Computer Science University of York

Looking inside before you buy etc.

by rhudson＠ix.netcom.com

>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).

Mac 800K floppy support (was Re: AppleTalk on the hoof)

PowerMacs certainly won't > do it, and I was pretty sure that most, if not all, of the '90s Macs > wouldn't either. 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 is interrupt driven, you need the jumpers for open slots. 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. Right front fingerpads 123 MEM CNTLR 2102E | not connected. And yes, the big board underneath everything is the mainboard with not a piggyback but a "piggytummy" smaller board attached to it. > Most typically in this system, the OS was genned for each card in a certain > slot.

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
