Hi Tony,
Saw your posts on the net regarding HX-20's. I was wondering if you would
be able to give me a couple pointers. I picked a hx-20 up a few years ago,
and am now getting a chance to play with it. I have downloaded and read the
3 PDF's on Epson's site. I have not been able to find a copy of the BASIC
Tutorial.
I have a ROM installed in the _bottom_ of the unit. Not in the expansion
slot, which is filled with the Cassette Unit.
Should the ROM be autodetected, or does it have to be loaded?
If loaded, how to I load it?
I have not been able to get things working experimenting with LOAD "PAC0"
and "LOAD PAC1".
When I first powered the HX-20 up years ago, it had a 3rd option, but then
I initialized it and of course, it is now gone.
Thanks in advance.

Wow! You guys are good. Maybe you can help me. I need some Fujitsu chip
information.
I have a bunch of Fujitsu MB15140 CR-G with a date code of 8809 I would
like to know what they are.
Picture at

I got them from Fujitsu, Hillsboro, OR, when they were discontinuing the 14" &
8" drive lines there. I suspect they are related to the 23XX 8" hard drives
but am not sure. Fujitsu made quite a few products there, POS stuff too.
Thanks for the help.

Wasn't that chip used in the Tandy TRS-80 Model 100 machines.
I remember playing with the Band Pass filters to convince the TRS-80 to work
with CCITT tones, instaed of the Bell tones that were used in USA. That was
a while ago
Boy, did I get myself into strife with the campus computer manager with
that little 300 baud modem.

thinking back some 18-20 years, you are right on this comment that the -YA -Yb
-YF variationd appley to the M9301 only, that module has no easy upgradable
proms, but standard multiboot configurations.
The keydifference is that M9312 stores one PDP11 instruction in 4 consecutive
nibbles of the prom, therefoere 1 Prom = 1 Bootdevice.
The 9301 has a conventional structure where the 4 proms are placed adjacent and
each prom provides 4 bits of the program. Therefore if you modify the 9301, all
4 proms must be changed at the same time. I had to do it once, adding a new
device to the boot routine, splitting it into the roms, burn those and get it
to work, and I remember it was a tedious job.

I just put up three docs at www.spies.com/aek/pdf/univac/univac3 that
will tell you more than you ever wanted to know about the Univac III
One of the reasons it wasn't very popular was they didn't maintain backwards
software compatibility with the I and II on the III.
A real computer doesn't know what the square root of negative one is? :-P

It significantly enhances its reality coefficient.
But a REAL computer has casters, (or a forklift)
A REAL computer dims the lights during power-up (for the NEIGHBORHOOD)
A REAL computer attracts attention from the Fatherland Security.
Hello Gene,
Even though RD-5x fit in there fine, what is probably an inexpensive
but more reliable solution than the RD-5x is to go with 5.25" FH
ESDI drives as some other "personal users" have done. They
come in larger storage capacities than the RD-5x drives too.
Pick up a Sigma SCD-RQD11/EC when it shows up on eBay
for around $35 to $50 ( or even less these days? ), and ask
Mark Green about an ESDI drive. He got all four ( some of them
around 600 Mb ) that I had a couple of years ago for what would
have averaged out to $10 each ( plus shipping ).
Best Regards

A friend of mine is getting heavily into building radios, digital clocks
(using nixie tubes and/or miniature vector displays), etc. from tubes.
I've been thinking that some of those nifty prototyping boards like we
used in high school would be great for him to use for testing new designs.
The ones I used had a base made of clear plastic with an array of
holes in the top which lead in sets of 5 or so to a common set of metal
contacts. There were dozens of sets of contacts on each board. The tubes
were mounted in sockets on small squares of PC board with traces leading
to pins along the edges. These pins would plug into holes on the base,
and you would plug wires into the other holes on the same contact strip to
connect something to that pin. There were also inductors, variable caps,
pots, etc. on small boards. Any idea where I might be able to buy
something like this setup these days?
Hi
I'm looking at buying a HP Apollo 9000 Model 710 32MB, can you give me a
price to buy??
