Today was a good day at the hamfest in Pomona, Cal. Unfortunately I should have written my name on my butt, cause that was the only part of me sticking up for the first hour or so. 6 boxes full of cards later I had five totally lame cards in my hand, and ended up putting all but one back. Just for yucks I started poking in some boxes of cables and found just what I needed. I bought 124 mac video cables, split between three rare types Radius Pivot, DB15 to 13W3, and 13W3 to 13W3. New Toy I found a TRS 80 pocket computer in the original box with software manual and cassette interface. Cute little monster, but it wants to eat Type 675 batteries at a rate of 4/300 hours. It warns against using a type 675E, but Radio Shack carried neither a plain 675 or a 675E, just a "replacement" for a whole slew (hee hee) of 675 this or thats called a RS675. Any ideas on a common modern equivalent battery? I bought one feeding of 4, and the thing comes right up, but regular feeding needs to be on a bargain brand of battery chow.

It's a pretty full-featured scientific calculator that you can also program in BASIC. They are in fact re"branded" Sharp pocket computers. In fact, Sharp still makes pocket computers, only nowadays they have agenda/phone book/stuff and aren't programmable in BASIC via a tiny QWERTY keyboard. What model do you have? I have a Sharp PC-1403H... with 32KB RAM! I bought 2 of them for 20 $ CAD each in a thrift shop. They were sold as-is, without manual, interface, nothing. I gave one to my brother. We are both searching high and low for the manual. I took mine apart and notice there's a pezo speaker in it. Only I haven't found out how to use it. Ideally, I want to write a video game for it :) About batteries : are you talking about batteries in the interface or in the PC itself? Mine came w/ 2x Sharp CR-2032 batteries. I had some problems with it, so I went to a watch store to get replacements to see if the battery was the problem (it wasn't, it was the power switch that had been put back on wrong) and am now using Renata CR-2032. When I bought mine, it had a program in memory for calculating taxes or something. I had to use the ALL RESET function to clear it from RAM and be allowed to program in BASIC. I'm wondering if this wasn't written in assembler or something. -Philip PS : be very wary taking it apart. The keycaps aren't attached to anything and will all fall out if you aren't careful :)

Any chance to get a copy (electronic or other) of the tech manual for the 1500? I did some search on the www to no avail.
