In the WinOSI download I think Dave.

Grant Use TK0 standard format 65U transitions from 8E1 to 8N1 after byte 3 of subsequent tracks. (I think this is where our noise byte comes from) TK1-76: wait index, set ACIA 8E1 $80,TKLO,TKHI delay some ms, set ACIA 8N1, write data $E00 bytes ie each track header as 8E1, sector data as 8N1 use the...

Im looking for a copy of the manuals for BASIC5 and Toolkt if you can help please. I wonder who received this UK101 with Premier Roms and manuals: http://www.ebay.com/itm/Working-Vintage-UK101-Computer-similar-Superboard-600-Challenger-1P-/131546581003?pt=LH_DefaultDomain_3&hash=item1ea0c9880b#ht_10...

Mike, are you near this interesting looking vintage computer museum at all : http://www.computinghistory.org.uk/det/6983/OSI-UK-User-Group-Newsletters/ I believe they loan gear out. I used to have those UK newsletters but they are lost in the mist too. Would be great to get scans of those for Daves ...

Well done Mike. I had a peek at Comp Shop on Google maps. Doesnt look like you will find caps lock key there now ! On to the Kim ? Will be interested to see your progger design. Do you have any software or other hardware for the UK101 ? In particular I am looking for info or manual on Premier Public...

remove the NB and add a byte at the end of the noisy track to maintain its length.

Thanks Danny. Just shows I cant rely on my (late night) memory any more!

43 57 01 58 NB 76 01 08 ... 65D
80 00 TK NB 1F code .... 65U

Well done Rich. Look forward to your updated version.
