There's also the unusual, little known but readily available and
programmable TMS2564 (Vpp also 25V, alas); it (sort of) stayed with
the original ROM/EPROM pinouts when everyone else switched to the

It's a 28 pin 8K x 8 EPROM, but the upper 24 pins are pi

That's how Cromemco shipped their distribution disks, with both holes and a
sticker to cover the unused hole with arrows on it to show which way was

Flipping disks to use both sides in a single-side drive was really only
feasible in Commodore and similar drives that did not rely on an index hole
for locating the data on the disk; the notch was to allow writing to the
disk and had to be added on the opposite edge.

If anybody actually wants to build one I have the important part, motor
driven with solenoid operated cam driven punches; would only need a
suitable interface and maybe a cabinet.
Don't know if it would be worth while with today's shipping costs though,
unless you're local in the Toronto area.

I've got a NEC board here with 8 x 27C010 1megabit EPROMs which AFAIK is
the postscript firmware for a NEC laser printer; any interest?

I believe I still have an LJ III and might still have parts from a scrapped
LJ II; I'll have a look.

There's a small discussion on S100computers about the terms 'skew' and
'interleave'.
In CP/M documentation 'skew' refers to what's usually called interleave
these days, i.e. offsetting sectors on a track to compensate for the fact
that by the time the computer has processed a given sector the next

What's the length and the diameters at each end of the pin? I've got some
cables for Burroughs patch panels that might be useful.

We had our Votrax T&T on one of the spare ports of a Cromemco/Cromix system
being used as a mail/BBS system; sort of a talking Caller ID announcing
when various users logged in.
Fun times...

Same here. Also works for soldering header pins etc.; stick a matching
connector on the other side of the board and they stay flush and
perpendicular.

I guess the L series would be considered smaller, different but more or less
equivalent to the B80.
I thought there was an L4000 and/or an L7000 in a museum out east somewhere; I
think Bill Degnan would know.
