Which TK2 version to use

[tcat]

Hi All,

I have a plain unexpanded QL, I wish to use toolkit TK2, I have a standard CARE cartridge and EPROM 16K.
I plan to program it with TK2, what version would you recommend for me?
My QL is JS ROM, one of the late SAMSUNG models.

Under uQLx emulator, I have tested these versions
V 2.12 - gives boot mesage CARE / QJUMP Toolkit
V 2.13 - seems not to recognize MDV2_
V 2.20 - gives boot message QJUMP Toolkit

I cannot really tell the difference, can you please advise?

Many thanks

Tcat,

I haven't seen any release notes (i.e. list of bugs fixed) beyond version 2.13 - TK2 has always been a pretty stable piece of software (with no known severe bugs or really new features), so I wouldn't care too much what exact version to use.

I'd probably use 2.20. (And I think that's the one I use on uqlx, too)

Tobias,

I see, the same file of my choice I use under uQLx, I can burn to EPROM, no tricks need to applied to the binary, correct?

Many thanks

Tom,

to be on the safe side, check the first 4 Bytes - They should be $4afb0001 - The start of a Standard QL ROM Header. If not, you probably have the RAM Version. (But if you're using the same thing in uqlx as a ROM - and not LRESPRing it, you should be all right.). Provided that's all right, it can directly be burnt into an EPROM.

All,

Hex dump shows $4afb0001 in all three files, I have freedom of choice, good.
It's a pity RAM disk is not part of TK2, but of floppy disk firmware, correct?
I use it as a separate extension.

Hi,

V 2.12 - gives boot mesage CARE / QJUMP Toolkit
V 2.13 - seems not to recognize MDV2_
V 2.20 - gives boot message QJUMP Toolkit

Just realised V 2.13 will only becomes active after TK2_EXT command is issued.

Hi,

Just saved Lightning ROM code from EPROM, I bought with CARE cartridge, and put version 2.20 of TK2 in place and it works.

QJUMP message appears in the initial screen after the boot.

Many thanks so far.

Hi,

I have a new observation.

I compared V 2.12 and V 2.20 roms, and in fact they differ only in a single byte (except having different version header), specifying, default DATA_USE and PROG_USE.

V 2.12 flp1_, flp1_
V 2.20 flp1_, flp2_

V 2.13 and V 2.12 as well as V 2.13 and V 2.20
differ in some 15767 bytes.

V 2.13 appears possibly a later version compared to V 2.20
