Paper tape encoding scheme needed

by bill_r＠inetnebr.com

I've been doing some web searching and reading the "TV Typewriter" book concerning puched tape encoding schemes, and I'm a bit confused. I've written a program to punch tape on my PC, and a short bit of code to read the tapes on my IMSAI 8080, but there are some problems. Since the unpunched tape leader looks just like a "zero" to the tape reader, I usually end up with some extra 0's at the start of my programs on the IMSAI. Also, I have a feeling that the tape reader may "eat" some of the codes if they're things like X-ON, X-OFF, etc, although I may be wrong. If I'm going to do something along the lines of using two 4-bit values to represent each byte, or an escape code to distinguish real 0's from leading blanks, and maybe include a full-width (FF) punch every foot or so to allow for easy folding, while having the reader software ignore them, I'd like to follow some kind of established standard. Can anyone give me any pointers on this? -Bill Richman (bill_r(a)inetnebr.com) Web Page: http://incolor.inetnebr.com/bill_r Home of the COSMAC Elf Microcomputer Simulator, Fun with Molten Metal, Orphaned Robots, and Technological Oddities.

There's also an alternate alternate procedure that would involve not running sys$system:startup.com or whatever, and just trying to run "authorize," installing the proper images until it stops complaining about not having them ;) Of course, that's the long way around.

NEC Multispeed boot error... what now?

by rigdonj＠cfl.rr.com

Rose, I still have my MultiSpeed (the original non-hard drive, non-back lit screen version). First you MUST have a good battery. I you don't want to buy a battery just for testing then you need to hook up a good regulated power supply (not a wall wart!) in place of the battery. The MultiSpeed that I have doesn't have the hard rive so I don't know if my DOS disk will work or not but it should at least get it to boot. I know where's there's a hard drive version of the MultiSpeed (MultiSpeed HD) and I may be able to get disks there. However IIRC the MultiSpeed is very IBM compatible and will boot and run IBM DOS. But IBM DOS won't have all the utilities. Joe At 04:07 PM 4/11/02 -0700, you wrote: > I am hoping you can send me in the right direction for restoring >this very old laptop that my father gave me.

TSV05 supported in V7M?

by lists＠subatomix.com

Google tells me that the TSU05 interface board, itself a rebadged Dilog board, emulates a TS11. Does anyone know for sure if this emulation is good enough to fool V7M UNIX? Google also tells me that the TS05 is slow. Are there any other issues with this transport, such as tape eating, or might it be pretty dependable? -- Jeffrey Sharp The email address lists(a)subatomix.com is for mailing list traffic.
