Notes The Epson was a neat little portable with tons of features. The plug-in application ROMs were a good idea in theory, but somewhat cumbersome in practice. The CP/M operating system, modified for the Geneva architecture, was probably implemented a few years too late. Competition with Tandy and PC compatible "notebooks" eventually killed the machine.
Related Items in Collection P-80 thermal printer, "Modem unit," most of the original manuals and paperwork except for the "Operations Manual" containing the CP/M, BASIC and system references. Four ROMs (BASIC, Wordstar, Calc/Scheduler, UTY (utility?)). The older Epson Lap top, the Epson HX-20.
Related Items Wanted External disk drive(s), Operations manual, additional ROMs.

The Epson Geneva in my collection is in excellent working condition with most of the original manuals and other items from the packaging (with the exception of the packaging itself and the main users manual.)

Cosmetically the machine is just about perfect with the possible exception of the keyboard cover which is slightly discolored, perhaps from manufacturing impurities.

The Epson Geneva Modem

The machine in the collection comes complete with the modem option which is a wedge shaped addition to the bottom rear of the case. Besides providing slow dial-up connectivity it has the added advantage of propping the keyboard up at a more comfortable angle.

Epson Geneva Micro-Cassette and ROM Module

The Geneva uses micro-cassettes for data storage and pre-programmed ROMs for most applications including BASIC and CP/M.

Epson Geneva PX-8 Documentaion

The machine came with most of the original documentation.

I'd love to get my hands on one of these... especially some of the add ons. This would be a great system to play with for embedded stuff....

I have one that I would like to find a good home for. You really can have too much stuff.

I also bought a HSN return, in 1985, PX-8 had the nicest feeling keyboard ever, mine still feels great, wish I could buy a PC compatable keyboard that feels this good! Mine has the 600 baud dial up modem and second battery backup wedge that screws on the bottom. Also the Wordstar, Basic, and Utility ROM chips.But the manuals were destroyed by mildew in storage. Ni-cad batterys removed because they started to corrode, but I saved the wire connections to them. Printer went away over 12 years ago and I trashed it...

I will give it to a legetimate museum if you cover cost to package and ship it from near Tampa, Florida, USA.

The PX 8 actually has 3 processors. The Z80 runs applications, while a 6301 handles the keyboard and screen, and a 7501 controll the other IO functions.

Bought one from DAK for about 300 bucks in the late '80s. Used it a lot on the road and acquired many cheap program modules including Wordstar and Dbase. Eventually the machine died; probably a bad battery. It's in my closet. I like the keyboard feel, the fact that you could also use the microcassette drive as a voice recorder and the accompanying printer. Sweet for its era.

I had in the Rome office two Epson Geneva PX-8 bought in the US since summer 1984 and I used them extensively to prepare documents. One of the two units was subsequently equipped with an additional RAM disk, which was attached to the bottom of the unit (like in the picture of the unit above a P - 80 thermal paper printer). I still keep them and the manuals. I should have also the thermal printer and the external 3.5' floppy drive somewhere in the cellar. Great machine for the time even if I thought its price was more than 1,800 USDlrs per unit. Good to know that there are people interested in these old computers which were the ancestors of our lap-top. I still keep all my PCs I had since 1984 because are part of my life.

I have a PX8, bought new in 1985. Still works, even after virtually living in a truck for 5 years- it was a gas having mobile word processing capabilities while my employer was still stuck with typewriters in their office.

I have one of these that I purchased on ebay. I'm looking for one of the elusive disk drives. If anyone has a disk drive for the PX-8 they would like to sell, please let me know.

I've got one of these too. I bought it from DAK. I also have the Seikosha pin printer.

I'll have to dig it out one if these days.

Since you have a PX-8 (I had one) y9u might know of a source for batteries for the HX-20. I'd appreciate reference to any battery sources.

I had one in 1987 . It was origanally sold on the Home Shopping Channel. I was working at a store that bought merchandise returned by customers. THe store received 3 of them and the owner of the store only wanted one of them. The person who checked them out kept one for himself and gave me one. Lasted a couple of years before moisture got into it and destroyed it. I had fun with it .

Oh wow! What memories. In 8th grade my parents bought me one of these from a DAK catalog. It was my first computer.

I bought one of these in 84' and used it to keep expenses and payroll on for my small electical contracting business. This little baby took all I could give with never a problem. I traveled all over the country with it and would keep every thing on the little cassettes then print out every thing when I returned. It was sold by mistake at a garage sale in the late 90's. Damn :-)

Ah...he machines I lusted after in my youth! I now own two, one with a full documentation set, modem, ROMS, soft shoulder case, external floppy drive, etc. Rarely used but always fun to take out and look! The things ran forever on a battery charge...regret that I have forgotten almost all of my Wordstar commands. Thanks for pictures!
