- Newell Industries used to / does sell a little board that would switch
- between OS ROMs on an XL/XE. It's called a Ramrod. I bought one along
- with an OmniView chip and destroyed my first 130XE trying to solder it in
- myself (I was ignorant of the damage that even a 25W soldering iron can do
- to a multi [dual] layer PC board). It would have cost about 3/4 of the
- cost of a new 130XE to repair it, said the repair shop, and we can put a
- socket in a new 130XE for the cost of the socket (plus the up-front fee
- that this place charges at the storefront). So I bought a new 130XE (this
- was around 1985/86) and had the shop put the socket in. I wrote off the
- Ramrod (it was soldered into the old XE board) but I sometimes wish I'd
- bothered to put it in. (I still could, but I'd have to desolder it from
- the old XE's board first, and cut a hole in the new XE's shielding, a
- switch hole in the case to avoid "hangy wires", etc.) But there are few
- programs that I have tried (not that I've tried thousands, but...) that
- just won't run under the OmniView OS. The @#$%^&* Electronic Arts _______
- Construction Set programs won't: "Remove Custom OS" is what the protection
- kludge told me. So I 'removed' the EA programs - sold/gave-away all two of
- them I had been given by a former 8-bitter. Letter Wizard won't, but it is
- a yukky WP anyway, OmniWriter 80 is better. And so on. The only regret is
- that Ace of Aces (cart.) wouldn't work.
