I know this is boring for all you rich A2000 owners but....
I remember hearing something about an Amazing Computing A1000 memory
hack that involved adding another 512K by soldering chips onto the
mother board. I finally have some chips, but am still too cheap
to buy an insider. Does anyone know where to find this article,
and has anyone tried this hack? Does it work?
Any info or advice would be gratefully accepted.
Cheers,
Stu

There was an article like that in AC Vol 2, #1, 1987. (This was before AC started putting real dates on their mags.) The technique involves soldering RAMs together to form RAM stacks, after first cutting their little toes off. Brrr, sounds scary! Want a copy of the article? - Cliff | |||||

Indeed does sound a little chilling....but what the heck... major
surgery never scared me off when I was working on other peoples
computers.
I'd love a copy of the article.
For anyone else out there who may be crazy enough to try this, I'll
post a report if I actually go through with it.

| 2199.3 | I did this one a few years ago.... | TIOGA::santiago | Drinking deeply of the Pierian spring | Sun Feb 12 1989 22:30 | 22 |
..it came out great. Still working fine these days. One hint: Stay clear of NEC RAMs. I had a *lot* of trouble with some, had to throw them away ($$ - ouch!). It turns out they were a bad batch, had different CAS/RAS timing. The date code on them was "L", so if you must go NEC be sure to avoid these. There're also a few mods you can make to get it to work under 1.2+. One of them involves latching on the drive LED, which is what I did. I don't recommend it. But if you do go this way, be sure to put the green LED in your console. One of the caps in the timing code (er, circuit) doesn't discharge well and when powering off/on quickly the circuit comes up enabled: Not Good. You have to keep power cycling until the green LED is off on startup, and everyone knows power cycling is a Bad Thing. Another way involves remapping the memory to $C0000000 with a few F parts, although I don't know how well it works, it sounds much better than what I have. PS I'm a software type, and that was my first exposure to a soldering iron. It was that easy. ^E | |||||
