<Yes, it was a real 360K disk, I just reformatted it in Windows (it will let <you choose between 1.2Mb or 360 formats). <____________________________________________________________ <David Vohs, Digital Archaeologist & Computer Historian. A 1.2mb drive does not produce reliable 360k media. It will read it but it's not symetric. Some 360k drives have more than normal difficulty reading disks created by a 96tpi drive. Allison

Large qty of GRiD external floppy drives available

by mrbill＠mrbill.net

Going by the goodwill today, they've got a LARGE quantity of external floppy drives (probably 15-20 at least) for the 2260 and 2270 models for $2.95 each. If anybody needs one for their GRiD, let me know, and I'll pick one up for you (already got one for each of my 2270s). They look BRAND NEW - no scratches/wear, and the connectors that plug into the laptop have a little blue plastic bag still over them.... Now, if I could just find a power supply and/or a pen.

GRiD 2270s

by mrbill＠mrbill.net

Anybody know where I can get info on these? I picked up 3 of them today, complete with batteries, but no power supplies or pens (they can be used as a "flat pad" mode, with a pen, or the screen flips up to reveal the keyboard). Any info would be appreciated.

Parallel port hard drives?

by allisonp＠world.std.com

<>Are you using a 1.2MB floppy drive to write a 360K floppy disk? < <Yes, but I used the drive (1.2Mb) to format it to 360K. <____________________________________________________________ <David Vohs, Digital Archaeologist & Computer Historian. There lies your error. 360k floppies are 48tpi, 1.2mb floppies are 96tpi. The intertrack spacing is different, head width is different. Find a real 360k drive, try again. These young apprentices... ;) Allison

FOCAL (was: KIM/6502 code)

by earl_evans＠yahoo.com

Hey Cameron, I'd be one of your first customers if you did :-) Just read a little about this device in the book "Fire In The Valley". (Book review coming...) Sounds like it was kind of groundbreaking, being among the first kits to provide a keypad for input, as opposed to toggle switches, etc. They have one on display at Powell's Technical Bookstore in Portland, OR. Wish I had one that I could light up. Maybe someday...

TU58 Peripheral Emulation

by mew_jac＠swbell.net

I believe Tim Shoppa has a TU58 emulator product. Maybe Tim can tell us the state and cost of the product? I also have some code gathered up over the last few years for DOS and Linux.

laptop failure modes

by red＠bears.org

I have a laptop given to me by a former co-worker who claimed it was broken. It doesn't fall into the ten-year category, but I've heard people complaining of failures just like this one in many other laptops. The laptop won't run if the battery is in the unit. AC or DC. If the battery is pulled, it will run on the AC adapter just fine. The battery itself seems fine as does the charging circuit. I can discharge the battery, insert it into the machine and have it be charged later (according to the charge indicator on the battery; I haven't checked it out with a DMM or anything). What is likely to cause this sort of fault? ok r.

Slightly OT: Need IBM Penpoint install disks for ThinkPad 730t

by nerdware＠laidbak.com

Yes, I know it's not that old, but if anyone would have a copy of an oddball OS, it'd be you guys..... I have a couple of 730t's that work, complete with the cute little PCMCIA hard drives, and the suitcase docking station with the Kodak Diconix printer. Only problem is, the OS is password locked and there seems to be no way around it. A friend has one drive with a clean, unlocked OS, but there is something about the little drives that Ghost just doesn't like. The tech at IBM was clueless, so I need the original install disks so I can wipe my machine back into usefulness. Anyone able to help? Thanks.

TU58 Peripheral Emulation

by allisonp＠world.std.com

<I've already asked John Wilson this, but has anyone compiled the one <available on dBit's ftp site for Linux? Or know of another one for <Linux/Windows that's available online? I'd like to try it out... I've looked at it and it's a bit old but should work. All a tu58 is if you ignor the tape drive itself is a 256k block addressable memeory at the end of a serial line talking a packet protocal. It only took 2048 bytes (with selftest and autoboot) of 8085 code to do it so it's not rocket science. Now to do that on a PC or whatever running most any OS is to beable to create a datafile of 256k and address any 512bytes block within it. So if you look at that code most of the work is working aound the OS! Allison
