I need to read some 8 hole paper tape, and I also need to read some
5.25" floppy drives, in both instances to transfer the data onto a
more current media. Any suggestions??? (The data is machine parameters
and test programs from a long defunct manufacturers of milling
(who only got rid of the facilities a couple of years ago when packing
up to move!!!!!!!)
Find a machine with a tapereader and an RS232 port.Read the tape in
and download to a laptop or just read direct of the tape,slow but
5.1/4" floppy to something else? email@example.com can
do it.He`s in the Midlands.
I know the problem, still have some old game programs on 5.25 discs
which I forgot to move across. I think I still have an old 5.25 disc
drive in a box, which could probably be fitted to a recent PC; let me
know if you are stuck and you can have/borrow it.

Why bother I have always assumed it would be happy on the std fd
ribbon. But I may be wrong!!!!! Mind you the panels are always OFF the
sides of my desktop.
I also have a 5 1/4 drive should you need it. No borrows or swaps it
is yours! Also a 1200 baud modem should you need it.
I think I have some 5 1/4 floppies as well, for backup <G>

I worked on process control systems in the '70s that were programmed
from paper tape - we kept the archives for each system in large
cardboard archive file boxes in a quiet corner of the factory.
Customer had a mishap with his master tapes and asked for a fresh set
from the archive - unfortunately, their archive box & contents had
been eaten by rats...
When I worked for Ferranti in process control we used miles of the
stuff. I remember Mobil's Coryton refinery one night when a total
reload was needed, the masters were in Coral 66 (or maybe Fortran)
and had to be complied onto the hard disk. The (Borroughs) 2 Mb disk
had 100 tracks and a head per track. I worked out we had loaded 14.2
miles of paper tape to generate the binary image on the disk, and that
must have been less than 2mB - a long night. But those were the days
when you could load a test program into core store in the office, and
take it to site to run.

That sounds very familiar...except that this was Kent Process Control
& we wrote everything in PDP-8 and PDP-11 assembler. I seem to recall
Ferranti was a major competitor. Generating a full set of listings &
binaries was a very long process - two passes through each source
tape, making sure they were all loaded in the right order...tedious in
the extreme. You had hard disks?? Luxury!!
I did a year with paper tape only, developing a control system. It
was hard work on paper tape, about 4-5 hours for an edit, assemble,
load cycle. At least it was ASCII, not 5 hole stuff. DECtape was the
way forward, just the right size for control system development in
assembler, and sufficiently robust to survive at the customer's site.
DEC were quite happy to extend our maintenance contract to cover site
work, but no way would they countenance an RK05 on site.
Pity about the RX01 floppy, already smaller than DECtape, but they
threw away 25% of what remained by writing 12 bits to two 8-bit bytes,
and another 4% by not using track 0. We had to wait until 1977ish for
RX02, for a DECtape sized floppy, by then the -8 was effectively dead.
Anyway, I liked the PDP-8 sufficient that I bought a secondhand
DECtape system 1979ish for home/business use. Just fitted in the
ingle nook by the fireplace.
I can remember my dad bringing old punched tape back from Grumman to
keep me amused in the early 1970s, paper tape was boring, the good stuff
was mylar?, blue on one side, bright shiny on the other. More permanent
I suspect and less palatable to small furry creatures.
If you're interested, there's a DOS program that'll let you read/ write/
format strange floppies. About the only things it won't do are format a
disc written in a 1.2Meg drive to be readable in a 360K drive, or
format/ write to a 3.25" HD floppy in a DD drive.
DOS only, unfortunately, but it'll fit on a 720K boot floppy with DOS 5.
<Looks> The same function's built in to Penguin based machines, if you
can jbex out how to do it.
