Yes, that would be great. I haven't gotten around to digging through
my old Kilobauds yet. Which other formats should I research?
I remember CUTS, but someone else mentioned 88-ACR and I'd never
heard of that. I'm sure Bell 103 is quite simple. Then there's
all the other cassette formats: CBM PET, VIC-20, C-64, Sinclair, etc.

You can still recognize them "by ear"? :-)

I seem to be reading a lot of good things about OS/2 here apart from the
price. Since it looks as though I may have found a source of decent
hard disk drives for my Compaq LTE Lite 20 machines I shall seriously
consider OS/2 for one of them. The other one, of course, will run
either Linux or Free BSD - Linux seems to have the vote so far.
Thankyou everyone.

I wasn't into computers at the time (I was 6 or 7) But my father used to
take me on Dumpster Safaris at Charleston Naval Base, where he worked
(civilian). Man, they used to throw out all sorts of stuff, some of it just
had a few scratches on it. I remember seeing oscilloscopes, radio gear,
terminals, tools, office furniture, you could live in one of those
dumpsters (Hey, I was 6. I didn't have great expectations.) My big thing
back then was swapping wires on connections, juicing it up, and see what
explodes. Now I'm all grown up! :)

I think this RD54 may have died. It DID have the spin-up disease, (Wouldn't
spin up), but this was just a bad case of stiction. I spun the disk and it worked.
Now, I try to format the disk (test 70 on uVAX 2000) and it acts funny.
Before, it would only recognise as unit 1. It would fail
the RdMbb step, format would be OK, and the Checkpass would take eternity.
(I let it run overnight, it completed 3 dots.)
I set it to unit 0, same trick but the RdMbb is OK.
Jumper problem?

I came across a program yesterday called GRiDROM.EXE. Apparently, it was
used to drive an EPROM Programmer via the GRiDCase 3's serial port. My only
question now is this:
Would this most likley be a proprietary EPROM Burner or could I use any
model, as long as it talked through the serial port?
I know nothing of EPROM Programmers, so be gentle. :)

You Smart Folks:
Can anyone give me some clues on a minimal set up to program boot ROMs
for IBM PC & AT comps. I want to build DOS & ? boot roms, but I only
have a faint idea where to start.
What's the minimum and what are some good lowend chips to use that can
be easily reused as development goes on??
Thanks,
-Mike

I'd start with the cables and connectors... Also try loading ,9 10 or
11, it is possible that they rigged that 1541 to be a higher device
number than 8. Have you tried reading the error channel:
10 open 15,8,15,"i0":rem initilize disk (no, this is not a format
command...)
20 input#15,e,e$,t,s:rem read error channel
30 close 15: print e,e$,t,s
if the disk is alive and device 9 it should report something like "0
ok 0 0"
> Anyone have one or two extra 1541 floppy drives they want to sell?
I find them pretty regularly at thrift shops and flea markets for a
fraction of what the shipping would be. I would suggest you hunt about
a bit first.
If you want to brush up on Commodore 8-bit drive usage I have two guides

All of the binders that I have have grey covers.

Nope, I don't have either of these files. I got 4 RK05 packs with this
system, three of which work. None of these disks have these files on them.
I'd love to get a whole copy of the V4 distribution, if you have it
(since it would match the manuals that I have). Right now, the only media
that my machine has is the RK05 disk packs. I'm looking to get a paper tape
reader/punch, but I haven't been able to find one yet. I'd also like to put
an RX02 (??) dual-floppy on it. Maybe in February, when I go to my Temple
Univ. "supply house."
What interface boards do I need to hang a dual-floppy off of the
PDP-11/34a?
