I just concluded a swap with Joe Rigdon (rigdonj(a)intellistar.net) and wish
to mention that he followed through with his end promptly and completely.
It is a pleasure to trade with him, and other persons on the list may feel
confident in doing so.

I just picked up two of these at a thrift shop, 2 floppies, cassette jack,
no hd. On the mounting plate of the floppy card is a female 37 contact 'D'
connector. Can any one tell me what this was for?

Sorry but the mice are not compatible between the Amiga and the 64, the
only pins that are the same are the joystick ones... You may want to
check this site out:
http://www.blackdown.org/~hwb/hwb.html
This is the location for the Hardware Book, which lists a vast number of
microcomputer pinouts as well as adapter wiring guides.

Hi!
Another lucky find - a Memotech MTX500 for $2. :) Beautiful computer -
aluminium case, nice looking external power supply, and black.
Unfortunatly it didn't come with any software or manuals. Does anyone
have a spare manual, or a couple of spare cassettes for it? i would like
to see what it was capable of. :)
Thanks heaps,
Adam.
If I remember correctly, The 1.2M drive uses a track 1/2 the width of the 360K drive. If you format a disk and write data with the same drive, there is no problem. The 1.2 drive can read down the middle of a 360K fat track and all is OK. The 360K drive can read the 1.2M skinny track and all is probably OK. The problem comes in when you use a 1.2M drive to write on a diskette that was previously written by a 360K drive. The skinny track is now on top of the fat track. The 360K drive will certainly have problems. It will read the new data in addition to 1/2 of the old data.

I had an IBM 360k that I was using, no compliants. I started having
data problems moving stuff from a true 1.2M to the 360. Later, I put a
360 in the other computer and I still had problems. Finally, I figured
it out, the IBM was either out of alignment, or shot...
Could it just simply be the 360k drive?

Just came across an Amiga/Atari switchable mouse, and was wondering if it
would also work on my C-64. Does anyone know if c-64 and amiga had the same
pinouts for the joystick port?

I thought all the pixels that would go bad do so during the assembly
process. Do they go bad on their own over time?

With all the discussion of disk exercisers, now might be an
appropriate time to post this stuff.
I have found a number of DEC and DEC-associated test sets. I have
three in my possesion and will wait to see if there is any response
to get the rest of the units. They seem to be in good shape,
w/manuals and adapter cables. I cant really *test* any of them
because I don't own any of the drives they are for. O well.....
I have here field test boxes for:
RK07/07
TB216A (CDC) (2 available)
RM03/05 (3 available)
Also there are:
DEC TDR Analyzer
Wilson Labs SX-530 Disk Memory Exerciser
Information Storage Tech. 7330 DDU Tester
Memorex 800 Disc Storage System Tester (7 of these available)
Memorex Mecanical Alignment Kit
Magnetic Peripherals Field Test Unit TB3A2A for RM0 series (3 avail)
DEC RM06/07 Carriage alignment tool
DEC RM02/3/5 Head Carriage tools (2 avail)
Condition of the devices I have in hand appears to be good, the
others have not been inspected by me personally, but the owner says
they're all about the same.
Prices on these units: (US) $50? $75? More? Less?
I am in Southern California. These devices are all in 'Zero'-type
cases.. shipping should not be a problem.
