I have a module that plugs into the side of the HHC and contains four
ROMs containing the SNAP (Forth-like) programming language for the
HHC. I sent Roger Merchberger a copy of the ROM images and he has
been trying to get this to work on internal ROMs but I don't think
he's been successful yet. Unfortunately, the pins were brittle on one
of the ROMs that I pulled from my module and several have broken off.
Until I find a machined pin socket to repair the broken ROM, I no
longer have a working module. The ROM image files are okay though.
The checksums on the image files match the checksums on the labels on

By coincidence, last week I spoke with guy who was software manager at
Friends Amis. He was moderately helpful; the best information he
was names of other Friends Amis people who were higher up and / or
the company earlier than he did. So now I'm trying to contact
and, of course, I will post updates here if / when I reach them.

Subject: Panasonic RL H1400 handheld computer
Can anyone tell me useful stuff about the Panasonic RL H1400
believe it was also sold under the Quasar brand name.
I've just bought one. As well as the machine (which I've not tested
got a little thermal printer/cassette interface, the AC adapter
mains), and 13 EPROMs in carriers. These seem to be insurance
a suprise -- NOT), but are at least UV-erasable EPROMs.
A few things :
I have of course taken it apart, it is painful to dismantle with wires
soldered between everything. The contemporary HP machines are a lot
With the bottom cover removed, you see the component side of the
I recognise the 6502 processor, some TTL and 4000-series CMOS
chips, 2 8K
ROMS soldered in, and 2 6116 (2K each) SRAMs. There's also a square
chip, looks to be custom (I/O???). Alongside that board is a 6V
with a fuse in series.
A bit more desoldering and unscrewing let me flip that board out of
On the underside is another TTL chip and a lot of SMD passives, etc.
The other PCB carries the keyboard contacts, the display, half-a-
PQFP chips (display drivers?) and a couple of 4071s, which IIRC are OR
There's an expansion connector on the end of the CPU board. 44
Looks to be the 6502 bus + power some others.
The printer also comes apart from the bottom. Its PCB contains a 4K
80 pin PQFP ASIC, a driver chip, and a few small logic chips.
the rest of the machine is a bit more tricky, all it contains is
mechanism and 4.8V-worth of NiCds.
I also cracked open the mains adapter.More complicated than I thought,
there's a regulator chip in there. And a fuse mounted in clips
(what is the
point of a clipped in fuse inside a glued case??).
Anyway, I've done a web search. Nothing very useful turned up. I
did read a
user manual on one site, which told me little that wasn't obvious.
Anyone got any technical information on it? Any useful software?
