Re: Psion Abacus
I have been playing with Abacus and Easel and I must say, even on a 128K machine with microdrives, it works pretty seamlessly. I can only imagine what 512K of memory, Choice, and a RAM disk would do the the experience. I guess I was ignorant of spreadsheets in the early 90s as I might have used Abac...

Psion Abacus
Does Abacus support the modulus operator? It has an int function and supports exponentiation both using ^ and the exp() function. I've tried all sorts of characters to no avail. I currently am computing a - int(a/n)*n, to compute a mod n, but it would be nicer to simplify it.

Re: Solid State Microdrive Cartridge?
So a small update on this. Just spoke to a colleague (a bit older than me) who, in the day, worked for Coleco helping design their version of the stringy floppy. He's going to look into some things I asked him regarding my plan and we may get together to test some things using my Spectrum and the sp...

Re: S3 Reset Switch replacement
The AliExpress link is to the user order page, not to a listing for switches. Can you post the correct switch?

Re: ntsc sinclar ql schematics ??
regarding the rgb output , will that still be the same as our uk versions ? The RGB is, yes. The one small difference is that the US QL's (as well as some other regions) don't seem to give a color composite signal on pin 1. Instead, it just outputs 5 volts. You can grab the composite off of the MC1...

Re: QL Pico VGA
Finally found the time to order a nice D-Sub hood for my miniaturized version. Type Conec 16-001810E. It has an optional side cable exit, the cable relief for it should be filed off a little. With the circuit fitted, it looks like this: qlminivga_case.jpg And the completed QL to VGA adaptor cable: ...

Re: Testing new pinch rollers solution...
I'd be interested in 4 to the US. Would love to see if my external drive would read better on both my QL and Spectrum.

Re: Get yourself a bargain (not) - £800 for an untested QL
Anyone who buys off of AliExpress ever go 5 or 6 pages deep and find $5 items for like over $1,000? What is going on there? I had to replace a mini AV-to-VGA converter that you can get for about $4, and I was trying to fit things into a "$10 and get free shipping" window and kept looking f...
