I use longer Pendrive with SF3, i did not have any problem.

It was easier to find the problem than recreate the files, i do not know what István used for packing, by loader size it seemed DTF with -m0, but -m0 was not supported for loader by those versions what i tried, i used DTF -m2 to pack it back.
The zip file contains everything for the next modification. I had to patch only one byte to fix the space issue
Please test it.

IS-BASIC also "cheats" if both numbers in an operation are 16 bit integers. FOR I=1 TO 1000 STEP 0.1 is slower than FOR I=1 TO 10000 STEP 1. But the overhead of checking for everything being 16 bit integers, converting integers to floating point when they are not, and deaing with 16 bit result overflow, means it is still not as fast as you would like (and I can't remember if TVC has this!)

Regarding TVC, Zozo's test was running much faster on TVC until the screen should not be scrolled, did you perform optimalization in TVC Basic in calculation, or the reason is simpler OS, and can reach routines faster on TVC?

I tested Herbert's example on Videoton TVC also, it finished under 47 seconds.

It finishes at 31 seconds. 5 seconds slower than a real or emulated CPC.

Seems to me that the CPC emulation on the EP is not as fast as a real or emulated CPC. Still much faster than either exdos basic or altair basic.

CPC emulation on the EP is only a modified CPC ROM, and some modifcation can cause little slowdown, ex if the CPC ROM is placed into video RAM, and AY emulation routine can cause slowdown also, as i remember it is called in each 300Hz interrutp.

Still wondering why the basic interpreters are relatively slow on an Enterprise. I did some more testing with the compiled version on both the EP and the CPC, and while the EP takes ~1.86 seconds (including disk access), the CPC version finishes about 2.6 times faster (~0.7sec).

This basic testing is not the best measurement of capabilities of a computer, because it tells mainly that how fast the basic itself, IS-Basic handles differently the numbers (if i know well) than other Basics, it uses in BCD format, number handling is slower in IS-Basic, and it is much more complex than others.

With disc accessing included the EP takes ~4.87 seconds, and the cpc ~1.9 seconds. Disc accessing seems slower as well on the EP, but I can't be sure without physical machines.

Obviously different compilers, and can't be directly compared - but still. The CPC hardware architecture might be more efficient? Not sure.

Floppy Disk i/o is much faster on Enterprise than on CPC. Normally most of the things can be solved faster on EP than on CPC, because the CPC uses 16 bit I/O ports, Enterprise uses 8 bit I/O ports, and accessing 8 bit I/O ports needs less cpu time, and there is one thing which needs too much instruction on CPC, accessing the keyboard, and AY, 1st you need to program the 8255 PPI to be able to access them, then you can address the needed AY port, and at the end PPI should be instructed again.

Where can I find those cables?

Write to Judge , he produces Monitor cables of good quality, and jostick adapters also up to 6 joy capable joystick adapters.

haaat a legegyszerubb az LPT-s megoldas, bar nagyon sok fazis kell hozza, de hogy ne kelljen ketfajta loadert irni, en csak ezt tudom elkepzelni, kb mint az antiriadban, csak meg tobb fazissal.
16 kb-ba a leheto legrovidebb LPT-vel kb 128 frame belefer, a mozgas is egyszeruen megoldhato, vizszintesen minimum 4 pixellel, fuggolegesen akar 1-gyel.
